Re: [Q] Does null column match null host var?

In article <2iqva0$c5j@delphinium.cig.mot.com> you write: } Hi, } } I have a question: } In an ESQL/C where clause, does an expression "column_name = $hostvar" } evaluate to true, if the column is null and the host variable is } set to null via rsetnull? } No. The only way for a test on a null value to be true is by using IS NULL or IS NOT NULL.
