Using LIKE with Variable Value not Literal Value….INSTR not optional

I'm trying to build a search type select statement constrained by a users input.....variable(x) which forces the use of like in the selection processing: x := (whatever user enters); I have tried with no luck: Select * from personnel where lastname like '%x%'; Select * from personnel where lastname like "'%" x "%'"; If you know of a way to pass a variable value to a like expression please let me know. Thank you for your time!

BAdams2,

I suggest you use bind variables to solve this problem. If that doesn’t work, you can always use dynamic SQL. Of course, bind variables are faster.

Here is a really informative link. Be sure to check out the follow-up section to the May 21, 2003 entry, as he uses like in the Where clause:

Hope this helps,
Charles
