Read the SQL reference manual, first.

Does this request "an explanation"?? !! Semantic?

Hi Madhu,
I got the answer. For example select Ac number from Cust table
EXEC SQL
SELECT ACCT_NO
INTO :EOP675ACCT-NO,
FROM EOP_AC_TABL
WHERE CUST_NO = XXXXXXXX
AND WIP-ID ? = 'D'
END-EXEC

Here WIP-ID not = 'D'. The not ( ? )symbol can be given as such.

Correct me if I'm wrong.

One more way of using NOT EQUAL is by using '<>'

Code:

WHERE ACCT_ID <> ' '

Both <> and ?= is working but 'not equal to' is not working

DB2 V8 doesn't support "?" character, so a good idea to use "<>".

One additional consideration when coding not equal ?<>? is that if you are tying to compare against a null, you will not get a ?true? condition. Therefore you will need to code as follows:

Code:

WHERE COL_1 <> ?ABC?
   OR COL-1 IS NULL
