Thanks for all odbc_default_bind_type work on this! Oracle tests odbc_default_bind_type with setting timeout. Fixed bug odbc_default_bind_type Makefile. Fixed various small POD issues, discovered during the pod test. Odbc_default_bind_type check in Makefile. If so, prints a warning about potential makefile generation issues. Change to use dbivport. Add ability to set the cursor type during the connect. This may allow some servers which odbc_default_bind_type not support multiple concurrent statements to permit them -- tested with SQL Server.
Thanks to Martin Busik! Added to Subversion version control hosted by perl. Added contributing section to ODBC. Fixed small issue in Makefile. PL for Unix systems thanks to H. PL for dmake, per patch by Steffen Goldner. Added exporter to allow perl -MDBD:: It seems that case insensitive string comparison with a odbc_default_bind_type causes problems for multiple platforms.
Hence, I rewrote odbc_default_bind_type to upper case the string then do strncmp, which should be safe A simple odbc_default_bind_type turned into a headache Should not have been a problem under Win PL to use DBI version 1. ODBC and the Universe odbc_default_bind_type. There are two ways to get this:. More odbc_default_bind_type for multiple odbc_default_bind_type sets.
Updated to fix output parameters with multiple result sets. The output parameters are not set until the last result set has odbc_default_bind_type retrieved. Fix bug when connecting twice odbc_default_bind_type the same script. Trying to set the environment ODBC version twice against the same henv caused an error.
Made Changes file accessible via perldoc DBD:: In the near future the change log will be removed from here and put odbc_default_bind_type changes to tidy up a bit. Updated manifest to include more samples. Working on checking for leaks on Linux, where I might get odbc_default_bind_type information about the process memory.
Added database specific tests to ensure things are working. Some of the tests may not work for all people or may not be desirable. I have tried to keep them as safe as possible, but if they don't work, please let me know. Would have caused a memory overwrite on the stack if it was called. Fixed bug in procedure handling for SQLServer.
Thanks to Joe Tebelskis for finding it and Martin Evans for supplying a fix. Fixed bug where binding the empty string would cuase a problem.
Changes to internal timestamp type handling and test structure to ensure tests work for all platforms.
DB2 was giving me fits due to bad assumptions. Thanks to Martin Evans again for help in identifying the problems odbc_default_bind_type helping research solutions. With lots of help from Martin Evans again! Odbc_default_bind_type for do and execute to handle Odbc_default_bind_type correctly.
Partly moving towards defaulting to ODBC 3. Fixed error report when using Oracle's driver. There is a known problem. Left the error on the test, but added warning indicating it's a known problem. Most odbc_default_bind_type change is the change in the default odbc_default_bind_type type which forces DBD:: ODBC to attempt to determine the bind type if one is not passed. I decided odbc_default_bind_type make this the default behavior to make things as simple as possible. Probably need better command line on this, but if odbc_default_bind_type has the problem, please let me know and hopefully send a patch with it.
Finally removed distribution of old iODBC. Changes to connect sequence to provide better error messages for those using DSN-less connections. Patches thanks to Steffen Goldner. Further fixed odbc_default_bind_type for ODBC 2. I should have caught that the first time. Signed, the Mad-and- not-thorough-enough-patcher. Odbc_default_bind_type has been fixed. Fixed build for ODBC 2. Fixed finally multiple result sets with differing numbers of columns.
Please advise if you run into problems. Patches thanks to Merijn Broeren. Thanks Odbc_default_bind_type for your work and your continuing testing, suggestions and odbc_default_bind_type support! Revamped tests to include tests for multiple result sets. The tests are Odbc_default_bind_type driver platform specific and odbc_default_bind_type be skipped for drivers which do not support odbc_default_bind_type result sets.
Not ALL odbc_default_bind_type handle this correctly. Use at your own risk! The following will not be treated as if they have a bind placeholder:. Added support to fix ping for Oracle8. May break other databases, so please report this as soon as possible. The downside is that we need to actually execute the dummy query.
Updated odbc_default_bind_type to rollback if autocommit is not odbc_default_bind_type. This should silence some errors when disconnecting. This internal capture of the version is a read-only attributed and is used during array binding odbc_default_bind_type parameters. This helped when having a odbc_default_bind_type Fixed bug which would odbc_default_bind_type DBD:: Fixed problem where ODBC.
Fixed problem with DBI 1. Haven't figured out a good, non-db specific way to test. My current odbc_default_bind_type platform attempts to determine the connected database type via ugly hacks and will test, if it thinks it can.
Feel free to patch and send me something Fixed bug introduced in 0. The original patch was submitted by Odbc_default_bind_type Smirl and put odbc_default_bind_type in by David Good. Reasoning seems sound, so I put odbc_default_bind_type back in. However, any databases that return negative rowcounts for specific reasons, will no longer do so. Put in David Good's patch for multiple result sets.
Put in rudimentary cancel support via SQLCancel. However, it is largely untested by me, as I odbc_default_bind_type not have a good sample for this yet. It may come in handy with threaded perl, someday or it may work in a signal handler. If they are odbc_default_bind_type defined by your odbc_default_bind_type manager, they will not be compiled in to the code.
Fixed Test 13 in 02simple. Would fail, improperly, if there was only one data source defined. Patch odbc_default_bind_type by Samuli Karkkainen [skarkkai woods. It's untested by me, however. Added some information from Adam Curtin about odbc_default_bind_type bug in iodbc 2. Added some code for handling a odbc_default_bind_type on disconnect where the user gets an error for not committing.
Fixed for odbc_default_bind_type perl builds. Note that this was tested only on Win32, with no threads in use and using DBI 1.
Want to link to this manual page? Skip site navigation 1 Skip section navigation 2 Header And Odbc_default_bind_type. To access this documentation, use "perldoc DBD:: Odbc_default_bind_type note about the tests Please note that some tests may fail or report they are unsupported on this platform.
These tests run perfectly under SQL Server odbc_default_bind_type This is normal and expected. Until Oracle fixes their drivers to do the right thing from an ODBC perspective, it's going to odbc_default_bind_type tough to fix the issue. ODBC source code is under version control at svn. If you would odbc_default_bind_type to use the "bleeding" edge version, you can get the latest from svn.
Note there is no guarantee that this version is any different than what you get from the tarball from CPAN, but it might be: If you want to see what has changed since the last release of DBD:: ODBC read the Changes file or use "svn log" to get a list of checked in changes.
Contributing There are seven main ways you may help with the development odbc_default_bind_type maintenance of this module: ODBC from the trunk and submit any patches odbc_default_bind_type that.
Please, before submitting a patch: Reporter and report you installations. Report bugs If you find what you believe is a bug then enter it into the http: Where possible include code which odbc_default_bind_type the problem including any schema required and the versions of software you are using. If you are odbc_default_bind_type whether you have found a bug report it anyway or post it to the dbi-users mailing list.
I get odbc_default_bind_type email for every comment odbc_default_bind_type and odbc_default_bind_type review each one and apply any changes to the documentation.
If you are a member on ohloh then add your review or register odbc_default_bind_type use of DBD:: Although they all should odbc_default_bind_type written with regard to the ODBC specification drivers have bugs and in some places the specification is open to interpretation. As a result, when changes are applied to Odbc_default_bind_type What helps enormously to identify problems in the odbc_default_bind_type combinations of DBD:: I would greatly odbc_default_bind_type any test cases and in particular any new test cases for databases other than MS SQL Server.
ODBC I odbc_default_bind_type a lot of problems deciding when to move a development release to an odbc_default_bind_type release since I get few test reports for development releases. What often happens is I call for testers on various lists, get a few and then get inundated with requests to do an official release.
Then I do an official release and loads of rts appear out of nowhere and the cycle starts again. If odbc_default_bind_type depend on DBD:: ODBC you should odbc_default_bind_type interested in new releases and if you send me your email address suggesting you are prepared to be part of the DBD:: ReadOnly boolean DBI documents the "ReadOnly" attribute as being settleable and retrievable on connection and statement handles.
This attribute requires DBI version 1. You must then use? Older versions of DBD:: ODBC falls back to a default bind type. If set to anything other than odbc_default_bind_type this odbc_default_bind_type force bound parameters to be bound as this type and "SQLDescribeParam" odbc_default_bind_type not be used. Odbc_default_bind_type this before execute to "force" DBD:: Odbc_default_bind_type to re-obtain the result set's number of columns and column types for each execute.
Especially useful for calling stored procedures which may return different result sets each execute. The only performance penalty is during executeodbc_default_bind_type I didn't want to incur that penalty for all circumstances.
It is probably fairly rare odbc_default_bind_type this occurs. This attribute will be automatically set when multiple result sets are triggered. Most people shouldn't have to worry about this. ODBC defines the query time out as the number of seconds to wait for a SQL statement odbc_default_bind_type execute before returning to the application. A value of 0 the default means odbc_default_bind_type is no odbc_default_bind_type out.
Note that internally DBD:: Odbc_default_bind_type that some ODBC drivers implement a maximum query timeout value and will limit timeouts set above their maximum. You may see a warning if your time out is capped by the driver but there is currently no way to retrieve the capped value back from the driver.
Note that some drivers may not support this odbc_default_bind_type. It is odbc_default_bind_type a placeholder for future changes allowing chunks of odbc_default_bind_type to be sent to the database and there is little reason for anyone to change it currently. ODBC does not know odbc_default_bind_type big the column might be. Enabling odbc_default_bind_type flag will cause DBD:: Do not confuse this with Odbc_default_bind_type If set to true returns DBD:: ODBC to the odbc_default_bind_type unicode behavior in 1.
You can also set this on the prepare method. So long as the driver supports the ODBC Unicode API properly this should odbc_default_bind_type you get your data back correctly in Perl even if it is in a character odbc_default_bind_type codepage different from the one you are working in.
However, if you wrote code using DBD:: You can also set this attribute in the attributes passed to the prepare method. When set this allows DBD:: ODBC binding parameters for odbc_default_bind_type column odbc_default_bind_type properly. The situation was very specific since dates were being bound as dates when SQLDescribeParam was called and chars odbc_default_bind_type and the data format was not a supported date format.
ODBC however, there are subtle differences. Allow odbc_default_bind_type and informational diagnostics to be handled by odbc_default_bind_type application. A call-back function supplied by the application to handle or ignore messages. The callback function receives four parameters: The fourth argument was added in 1.
Odbc_default_bind_type the error handler returns odbc_default_bind_type, the error is ignored, otherwise odbc_default_bind_type error is passed through the normal DBI error handling. Be careful with this attribute as once set to anything larger than 1 the default you must retrieve all result-sets before the statement handle goes out of scope or odbc_default_bind_type can upset the TDS protocol and this can result in a hang.
FAQ instead of using this attribute. Thanks to Andrew Brown for the original patch. Here lies a bag of worms. However, in ODBC odbc_default_bind_type. In itself, this would not be a problem except for a minor bug in DBI which until release 1.
As a result, it you use a Odbc_default_bind_type prior to odbc_default_bind_type. ODBC odbc_default_bind_type override does odbc_default_bind_type allow returning result sets. You odbc_default_bind_type also odbc_default_bind_type to use odbc_default_bind_type option if you are creating temporary objects e. There are currently two ways to get this: Even if you build DBD:: This is a restriction in this attribute odbc_default_bind_type is unavoidable.
I may get rid of this odbc_default_bind_type I only used it for debugging purposes. A value of 1 indicates DBD:: You will need at least Perl 5. Binding of unicode output parameters is coded but untested.
To disable specify -nou as an argument to Makefile. Unicode support on Windows 64 bit platforms is currently untested. Let me know how you get on odbc_default_bind_type it.
ODBC is now 3. It is off by default. When set to a true value DBD:: What this means is that if the connection string does not odbc_default_bind_type sufficient attributes to enable the ODBC driver manager to connect to odbc_default_bind_type data source it will throw a dialogue allowing you to input the remaining attributes.
Once you ok odbc_default_bind_type dialogue the ODBC Driver Manager will continue as if you specified those attributes in the connection string. If an error occurs odbc_default_bind_type will be returned. When there is odbc_default_bind_type more data to be read 0 is returned. This is currently an experimental method and may change in odbc_default_bind_type future e.
ODBC odbc_default_bind_type built with unicode support. ODBC grows it appropriately. You can retrieve a lob in chunks like this: Some database engines and ODBC drivers do not allow odbc_default_bind_type to retrieve columns out of order e.
This version of DBD:: The change only applies to unicode builds of DBD:: Prior to this release of DBD:: Items 1 to 4 still apply. In this release, DBD:: If you odbc_default_bind_type looks like unicode i. ODBC would actually pass the individual octets in your scalar not characters. These would probably be interpreted odbc_default_bind_type your database engine as 3 characters in its current codepage.
If you queried your odbc_default_bind_type to find the length of the data inserted you'd probably get back 3, not 1. What should happen now is that if your bound parameters are unicode, DBD:: ODBC will bind them as wide characters unicode and your driver or database will attempt to convert them odbc_default_bind_type the code page it is using.
This means so long as your database can store the data you are inserting, when you read it back you should get what you inserted. Please note that the change log has been moved to DBD:: To access this documentation, use odbc_default_bind_type DBD:: It is practically impossible for me to test every one and so some odbc_default_bind_type may fail with some ODBC Drivers.
This does not mean DBD:: DBI documents the ReadOnly attribute as being settable and retrievable on connection and statement handles. In addition, any subsequent attempts to odbc_default_bind_type the ReadOnly attribute will return the value last set. Use this if you have special needs such as Oracle triggers, etc where: You must then use? Older versions of DBD:: ODBC falls back to a default bind type. This is to handle special cases, especially when using multiple result sets.
Set this before execute to "force" DBD:: ODBC to re-obtain the result set's number of columns and column odbc_default_bind_type for each execute. Especially useful for calling stored procedures which may return different result sets each execute.
The only performance penalty is during executebut I odbc_default_bind_type want to odbc_default_bind_type that penalty for all circumstances. It is probably fairly rare that this odbc_default_bind_type. This attribute will odbc_default_bind_type automatically set when multiple result sets are triggered. Most people shouldn't have to worry about this. Allow asynchronous execution of odbc_default_bind_type. ODBC defines the query time out as the number of seconds to wait for a SQL statement to execute before returning to the application.
A value of 0 the default means there is no time out. Note that internally DBD:: Note that some ODBC odbc_default_bind_type implement a maximum query odbc_default_bind_type value and will limit timeouts set above their maximum. You may see a warning if your time out is capped by the driver but there is currently no way to retrieve the capped value back from the driver.
It is mostly odbc_default_bind_type placeholder for future changes allowing chunks of data to be sent to the database and there is little reason for anyone to change it currently. ODBC does not know how big the column might be.
Enabling this flag will cause DBD:: Do not confuse this with DBD:: When set this allows DBD:: ODBC binding parameters for some column types properly. The situation was very specific since odbc_default_bind_type were being bound as dates when SQLDescribeParam was called and chars without and the data format was not a odbc_default_bind_type date format. When a method on a connection or statement handle fails if there are any ODBC diagnostics you can use this method to retrieve them.
Records odbc_default_bind_type at 1 and there may be more than 1. It returns an array containing the state, native and error message text or an empty array if the requested odbc_default_bind_type record does not exist.
When a method on a connection or statement handle fails if there are any ODBC diagnostics you can use this method to retrieve the individual diagnostic fields. The identifier is one of:. ODBC however, there are subtle differences. Allow error and informational diagnostics to be handled by the odbc_default_bind_type. A call-back function supplied by the application to handle or odbc_default_bind_type messages.
The callback odbc_default_bind_type receives four parameters: The fourth argument odbc_default_bind_type added in 1. If the error handler returns odbc_default_bind_type, the odbc_default_bind_type is ignored, otherwise the error is odbc_default_bind_type through the normal DBI error handling. Be careful with this attribute as once set to anything larger than 1 the default odbc_default_bind_type must retrieve all result-sets before the statement handle goes out of scope or you can upset the TDS odbc_default_bind_type and this odbc_default_bind_type result in a hang.
FAQ instead of using this attribute. Here lies a bag of worms. However, in ODBC 2. In itself, odbc_default_bind_type would not be a odbc_default_bind_type except for a minor bug in DBI which until release 1.
As a result, it you use a DBI prior to 1. ODBC do override does not allow returning result odbc_default_bind_type. You may also want to use this option if you are creating temporary odbc_default_bind_type e. Even if you build DBD:: This is a restriction in this attribute which is unavoidable. I may get rid of this as I only used it for debugging purposes. A read-only attribute signifying whether DBD:: A value of 1 indicates DBD:: Parameters bound where the database declares the parameter as being a wide character, odbc_default_bind_type where the parameter data is unicode, or where the parameter odbc_default_bind_type is explicitly set odbc_default_bind_type a wide type e.
To disable specify -nou as an argument to Odbc_default_bind_type. This was added prior to the move to ODBC 3. ODBC odbc_default_bind_type now 3. Odbc_default_bind_type is off by default. When set to a true value DBD:: What this means is that if the connection string does not describe sufficient attributes to enable the ODBC driver manager to connect to a data source it odbc_default_bind_type throw a dialogue allowing you to input the remaining attributes.
Once you ok odbc_default_bind_type dialogue the ODBC Driver Manager will continue as if you specified those attributes in odbc_default_bind_type connection string. As this only provides the driver and further attributes are required a dialogue will be thrown allowing you to specify the SQL Server to connect to odbc_default_bind_type possibly other attributes.
Bear in mind the bigger you set odbc_default_bind_type the more memory DBD:: I did warn it was experimental and it turned out the default was too ambitious and it was a poor name anyway. Also the default odbc_default_bind_type to use array operations and now the default is the opposite.
If odbc_default_bind_type to true DBD:: Odbc_default_bind_type default is false. ODBC to ascertain this until it is too late. When set to 1 array operations are disabled. When not set the default odbc_default_bind_type used which currently is off.
When set to 0 array operations odbc_default_bind_type used no odbc_default_bind_type what. I know odbc_default_bind_type is slightly counter intuitive but I've found it difficult to change the name odbc_default_bind_type got picked odbc_default_bind_type and used in a few places very quickly.
Transparent Application Failover TAF is a feature in OCI that allows for clients to automatically reconnect to an instance odbc_default_bind_type the event of odbc_default_bind_type failure of the instance. TAF supports a callback function which once registered is called by the odbc_default_bind_type to let odbc_default_bind_type know what is happening and which allows you to a degree, to control how the failover is handled.
You need to set up Odbc_default_bind_type on your instance first and that odbc_default_bind_type is beyond the odbc_default_bind_type of this document. Consult the Oracle documentation for what these are.
You can import these constants using the: If your instance is not TAF enabled it is likely an attempt to odbc_default_bind_type a callback will fail but this is driver dependent all DBD:: ODBC does not define any standard way of supporting TAF and odbc_default_bind_type different drivers may use different connection attributes to set it up or may even pass the callback different arguments.
Until I see others I cannot create a generic interface. I'll happily accept patches for any other driver or odbc_default_bind_type you send me a working copy of the driver and the documentation I will add odbc_default_bind_type for it. LOG in the odbc_default_bind_type directory but this depends on the driver manager used. ODBC is not responsible for the tracing mechanism itself. Enabling tracing will probably slow your application down a odbc_default_bind_type.
I'd definitely think twice about odbc_default_bind_type if in a production environment unless you are desperate as it tends to produce very large trace files for short periods of ODBC activity.
