QUERY AGAINST SYSCAT.MODULES MAY RETURN UNEXPECTED RESULT SET IN ORACLE COMPATIBLE DATABASE | |
product: | |
DB2 FOR LUW / DB2FORLUW / 980 - DB2 | |
Problem description: | |
On a database created with Oracle compatibilty (e.g. DB2_COMPATIBILITY_VECTOR=ORA), query against catalog view SYSCAT.MODULES may return unexpected result set if any predicate references the column DIALECT. In the case where the length of the DIALECT value is less than 10, the view text definition causes the value to be blank-padded in the end. For example, db2 "select DIALECT from SYSCAT.MODULES where MODULENAME='PACKAGE2' AND DIALECT = 'PL/SQL'" DIALECT ---------- 0 record(s) selected. db2 "select DIALECT from SYSCAT.MODULES where MODULENAME='PACKAGE2' AND DIALECT = 'PL/SQL '" DIALECT ---------- PL/SQL 1 record(s) selected. Some side-effects include hitting SQL0204N error when deploying a PL/SQL package after copying it from the data source explorer to data project explorer on Optim Development Studio (ODS). | |
Problem Summary: | |
**************************************************************** * USERS AFFECTED: * * All * **************************************************************** * PROBLEM DESCRIPTION: * * Catalog views SYSCAT.MODULES and SYSCAT.MODULEOBJECTS havea * * CASE expression wrapped by a CAST function intheir * * definition. The CASE expression, when evaluatedunder * * VARCHAR2_COMPAT on, has a result type of CHAR(n)because the * * literals are fixed chars so the column valuewill end up with * * with length of n (the column length) byadding trailing * * blanks even if the actual value is less thann. * **************************************************************** * RECOMMENDATION: * * Upgrade to version 9.8 fixpack 3 * **************************************************************** | |
