You could consider using the COALESCE function to substitute another value
for the null.
The COALESCE function can also handle a subset of the functions provided by
CASE expressions. The result of using COALESCE(e1,e2) is the same as using
the expression:
CASE WHEN e1 IS NOT NULL THEN e1 ELSE e2 END
VALUE can be specified as a synonym for COALESCE.
Example 1: Assume that SCORE1 and SCORE2 are SMALLINT columns in table
GRADES, and that nulls are allowed in SCORE1 but not in SCORE2. Select all
the rows in GRADES for which SCORE1 + SCORE2 > 100, assuming a value of 0
for SCORE1 when SCORE1 is null.
SELECT * FROM GRADES
WHERE COALESCE(SCORE1,0) + SCORE2 > 100;

Your assumption is correct.
I donot want to allow null values into file FILE for OPTCOD.. where as
BSCFILE allows null for NOPTCOD..
I tried execute but Iam not correct as per SQL. How do I modify my sql
further...
update file a set optcod=(select
noptcod from bscfile b
where a.optcod=b.ioptcod and b.noptcod is not null
Warm Regards,

file
OPTCOD in file FILE isn't allowed that feature, and that in the former
file
one or more of the NOPTCOD fields are null. You can either change the file to allow null on OPTCOD or add "and b.noptcod is not null" to your WHERE clause. Joseph Pascoguin wrote:Hi when I run below qry I get "Null values not allowed in column or variable

I 've an xl sheet from the client to replace optcod values with new optcod values. xl sheet contains 5 columns futcod, descr, client &optcod I did simple sql UPDATE file SET optcod='OPTWS' WHERE futcod='FUT01' AND Client='GOLDMAN' and optcod='INXMO' Since the number of entries(around 50) in the xl sheet are less, I opted for this simple manual SQL. How to handle this differently by using a program when the list is big or some times we get 3 to 4 xl sheets from the client(optcod values changes from time to time!)?Warm Regards, JoeP _________________________________________________________________ Express yourself instantly with MSN Messenger!
