Run an ODBC trace to trap any preceding errors and assist in identifying the call that is causing the error. 6. Perform a SQLTrace and look up the error code returned in the call to SQLErrorW in the trace. For example:SQL0901This error corresponds to:SQLSTATE 58004 Cause: An SQL system error has occurred. The current SQL statement cannot be completed successfully. The error will not prevent other SQL statements from being processed. Previous messages may indicate that there is a problem with the SQL statement and SQL did not correctly diagnose the error. If precompiling, processing will not continue beyond this statement. Recovery: See the previous messages to determine if there is a problem with the SQL statement. To view the messages, use the DSPJOBLOG command if running interactively, or the WRKJOB command to view the output of a precompile. An application program receiving this return code may attempt further SQL statements. Correct any errors and try the request again. The SQLCODE is -901 and the associated message is SQL0901. 7.

SQL0901 error is an incredibly frustrating error that occurs with i5 ODBC, OLE DB, and JDBC connections. Because SQL0901 is a general SQL error, it can be difficult to diagnose and harder to solve. This week I will look at one specific SQL0901 scenario, where the failure occurs inside SQL's extended dynamic package support, and I will show you how to deal with this error in an i5 environment. What is Extended Dynamic Package Support? While the SQL0901 error can refer to a broad range of issues, this article focuses on diagnosing and correcting problems associated with SQL extended dynamic package support (package support). When enabled, package support tells i5/OS to save http://www-01.ibm.com/support/docview.wss?uid=swg21332180 the data access plans that the i5 query optimizer creates for your prepared SQL statements. The optimized access plans, which are sometimes called implementation plans or access paths, are saved in an i5/OS object called an SQL package (object type *SQLPKG). They are saved every time that a client submits any new SQL statement to your i5 box through an ODBC, JDBC, or OLE DB driver. When a client submits a previously executed SQL http://www.itjungle.com/fhg/fhg091306-story03.html statement using package support, the i5 box will use the optimized access plan information in the client's SQL package (along with the database host server's extended dynamic package, an i5/OS object called QZDAPKG) to process that statement faster. The performance improvement occurs because the stored access path does not have to be regenerated, which is particularly valuable if many users are executing the same or similar statements. It is also valuable because SQL packages are permanent objects, which can be accessed by users over many different i5 sessions. According to IBM, package support is available for many, but not all, SQL statements submitted to an i5 partition. IBM says that it supports iSeries Access ODBC cached packages for positioned UPDATE and DELETE statements, INSERT statements that use subselect parameters, and the DECLARE PROCEDURE statement (though there is a procedure for overriding these restrictions). For SQL statements from other sources, there is a larger list of allowed statements. Information on which SQL statements can be used in which connectivity environments can be found at the IBM SQL Questions and Answers Web page. Additional information about creating, saving, and working with SQL commands in packages can be found on the SQLThing Web site. How to Tell When Good Packages Go Bad The package support scenario generally works well but it can b
