Message . . . . :   SQL statement not allowed.  
Cause . . . . . :   The SQL statement is not allowed for one of the 
following 
  reasons:  
    -- DECLARE CURSOR, DECLARE STATEMENT, FETCH, OPEN, CLOSE, WHENEVER,  
  PREPARE, EXECUTE, EXECUTE IMMEDIATE, INCLUDE, DECLARE TABLE, DECLARE  
  VARIABLE, DECLARE PROCEDURE, and DESCRIBE are not allowed in interactive 
 
  SQL, dynamic SQL, or using the RUNSQLSTM command.  
    -- BEGIN DECLARE SECTION and END DECLARE SECTION are not allowed in  
  interactive SQL, in dynamic SQL, in RPG, or in REXX.  
    -- A blocked INSERT statement is not allowed in interactive SQL or 
dynamic
  SQL.  
    -- The CONNECT, SET CONNECTION, RELEASE, and DISCONNECT statements are 
not
  allowed in dynamic SQL. CONNECT with constants specified for user ID and 
 
password is not allowed in a precompiled program.  
  -- SELECT cannot be issued from an EXECUTE IMMEDIATE statement or the  
RUNSQLSTM command.  
  -- The SET OPTION statement is only allowed in REXX, in a precompiled  
program, or in SQL routines.  In a precompiled program, it must be the 
first
SQL statement in the program.  
  -- DECLARE STATEMENT, DECLARE VARIABLE, DECLARE PROCEDURE, INCLUDE, 
SELECT
INTO, WHENEVER, blocked INSERT, and blocked FETCH statements are not 
allowed
in REXX.  
  -- The SET TRANSACTION statement is not allowed when the current  
connection is to a remote database.  
  -- The SQL statement specified is not a valid statement on the current  
release of DB2 UDB for iSeries.  The statement may be valid on a future  
release of DB2 UDB for iSeries or on a system other than an iSeries.
