Re: Embedded SQL in ILERPG

Some choice passages from the SQL Programming manual:

Every SQLCODE has a corresponding message in message file QSQLMSG in
library QSYS.  The
message ID for any SQLCODE is constructed by appending the absolute value
(5 digits) of the
SQLCODE to SQ and changing the third character to 'L' if the third
character is a 0.  For
example, if the SQLCODE is 30070, the message ID is SQ30070.

A complete listing of DB2 for OS/400 SQLCODEs and their corresponding
SQLSTATEs is provided in Appendix B of the DB2 for OS/400 SQL Programming
book, SC41-3611.

Message ID . . . . . . . . . :   SQL0305

Message file . . . . . . . . :   QSQLMSG

  Library  . . . . . . . . . :     QSYS



Message . . . . :   Indicator variable required.

Cause . . . . . :   A FETCH, an embedded SELECT, or a CALL statement has

  resulted in a null value, but an indicator variable was not specified for

  host variable &2.  The relative position of the host variable in the INTO

  clause or parameter list is &1. If the host variable name is *N, an SQLDA

  was specified.

Recovery  . . . :   Specify an indicator variable, and precompile the
program
  again.



You should see this message in the job log, too.

Subject:  Embedded SQL in ILERPG





 Hello all,

I am trying to retrieve data from an Oracle database using Oracle Access
Manager
and embedded SQL in ILERPG.

I am selecting 12 columns from the ORacle table and inserting into a PF
locally.
I have problems with one of the Oracle columns and if I remove this column
everything works fine.

The problem is this: On  Oracle the field is defined as :
DESCRIPTION_2_TXT      VARCHAR2(30)
In the records that I need to retrieve, all the values are blank in this
column .
After I FETCH the cursor, SQLCA has the following values ( I've just pasted
the
msgs that I think are relevant)

  SQLCA                 DS
      SQLCOD              BIN(9,0)             -000000305.      'FFFFFECF'X
..
