Clients execute DB2 stored procedures in different ways, depending upon the SQL transformation mode in effect.
In passthrough mode, the command is:
{call procname(parm1, parm2, ... parmn )}
or
{call procname( ?, ?, ?, ..., ? )}
where procname is the name of the stored procedure.
In sybase mode, the command is:
EXEC procname argvalues
EXECUTE procname argvalues
where:
procname is the name of the stored procedure.
argvalues is a list of argument values separated by commas.
