Problem IC77233 Status: Closed

DB2COMMANDBUILDER.DERIVEPARAMETERS() FAILS TO FIND PARAMETERS FOR STORED
PROCEDURES IN IDS ANSI MODE DATABASES

product:
DB2 CONNECT / DB2CONNCT / 970 - DB2
Problem description:
If you execute the following example code against an IDS Ansi 
mode database, the DB2CommandBuilder.DeriveParameters() call 
does not identify any parameters for stored procedures. 
 
reproducible test:

Local Fix:
The problem is caused by the DB2 .NET Provider improperly 
providing the fully qualified name of the stored procedure 
resulting in the procedure not being found.  As a work around to 
the problem, provide the fully qualified stored procedure name 
in the DB2Command.CommandText property.

Solution
Problem was first fixed in Version 9.7 Fix Pack 5.  At a 
minimum, this fix should be applied on the client.
Workaround
As a work around to the problem, provide the fully qualified 
stored procedure name in the DB2Command.CommandText property.
