Ed, You should still have a WHERE clause :
SELECT * FROM ROWS AS R1 LEFT JOIN ROWS AS R2 ON (R1.index=R2.index AND R2.X<=Right) LEFT JOIN ROWS AS R3 ON (R1.index=R3.index AND R3.X>=Left) LEFT JOIN ROWS AS R4 ON (R1.index=R4.index AND R4.Y>=Bottom) WHERE R1.Y<=Top Does this work?

Unfortunately, when I do that (I'm not much of a JOIN expert <g>) I end up selecting ALL the rows in the table. - Ed -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
