#1097 DB2: don't display UDF source : SQL0206N "SCHEMA" is not valid in the context where it is used.


since version 3.5 Squirrel doesn't show source code of DB2 UDF.
Version 3.4 shows it.
pls. see attached screens.
I've checked it on 2 machines and with db2 app driver and db2 net driver.

Win7 prof. 64bit:
C:\DEV>java -version
java version "1.7.0_40"

Tried also different DBs (V9.7.7 / 9.7.8) on AIX and Windows.

    I have had the same problem.
    Error : when trying to see Source Code for UDFs, an SQL error is thrown. Tab does not display udf source code.

    2014-07-10 15:34:13,477 [AWT-EventQueue-1] ERROR net.sourceforge.squirrel_sql.client.session.MessagePanel - privateShowMessage: Exception was DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=SCHEMA, DRIVER=3.65.77

    Reason : the sql to select the code of the udf from the system catalog in db2 is not generated correctly.
    The sql ist not suitable for LUW.

    File : DB2 Plugin : DB2SqlImpl.java getUserDefinedFunctionSourceSql()

    Line 60 missing BREAK in case LUW: results in running into ZOS Block and wrong SQL being generated

               case LUW:
                       result =
                                "SELECT " +
                                   "case " +
                                   "    when body is null then 'No source available' " +
                                   "    else body " +
                                   "end " +       
                                   "FROM SYSIBM.SYSFUNCTIONS " +
                                   "WHERE schema = ? " +
                                   "AND name = ? " +
                                   "AND implementation is null ";         
                        // break; is missing
