BUG #: 101265 (SQLBUG_70)
SYMPTOMS
A stored procedure that accepts a parameter, which is used to determine how many columns to add to a temporary table that the stored procedure creates, might continue to use the value of the parameter passed the first time the procedure was executed, even though different values are passed for subsequent executions.
WORKAROUND
Create the procedure using a WITH RECOMPILE clause.
STATUS
