Hi,

trying to update table using UPDATE-SQL and keep getting an error, that field "grno" doe snot accept NULL value.
First of all, it happens only when I run EXE, never in APP. and second, I am using NVL function to prevent any NULLs.

Please see the simple code below:
UPDATE PS1;
SET PS1.grno=NVL(ID.grno,SPACE(6)) ;
FROM PS1 ;
LEFT OUTER JOIN ID1 ON UPPER(PS1.employeeid)=UPPER(ID1.employeeid)

I tried to use INNER JOIN, but received the same error message.

And by the way, I modified the table PS1 to allow NULL value in the field "grno".

Any ideas?

Thanks
Jerry
