I would first tell her about SQL and show how an Over clause works. That's a sure bet....
Here's an example
SELECT
ss.NAME
,ss.SPONSOR_NAME
,ss.DATE_OF_CALL
FROM
(SELECT
*
,MIN(DATE_OF_CALL) OVER (PARTITION BY SPONSOR_NAME) AS MinDoc
FROM
Testing_Name) ss
WHERE
ss.DATE_OF_CALL = ss.MinDoc;
Hai All,,
Thank you for your help for this case,,I'd like to follow your suggestions..
Thank you very much
