Thanks. We'll let you know when a new response is added.

Hello Rajalakshmi08,
I don’t remember how Delphi handles the null fields, anyway you can bypass the problem by filling the null fileds of your query with 0.
Example:
<pre>
SELECT (ISNULL(MYFIELD,0)) AS MYVAL FROM MYTABLE
</pre>

The query above will retunn 0 if the <i>MYFIELD=Null</i>.

Bye
