Problem in Wilcard Search (%) with Prepared Statement

Question

Hello Everyone,
Im trying to search using the like operator within a prepared statement. The program compiles , but when I execute it I get an empty result set.
I tried the same query in Query Analyser in SQL Server 2000 and it worked flawlessly.
I searched on this forum also and I read recommendations suggesting
to put the ? in like '?'   This gives me an error.
Ive tried all options I could get my hands on ,now I request you all to please provide me some guidance.
Thankyou
The code snippet is as follows :
          String  sDay= "%"+startDay+"%";
                ps= con.prepareStatement("Select  *  from Testdb  where days like ? ");
          ps.setString(1,sDay);
          As I said earlier, this query returns and empty result set.
Thankyou once again.

Answer 1

Its next to impossible for me to switch to Statement from prepared S. because the Query has got way to many conditions and its next to impossible to handle all those in a statement.
I had originally started out with statement itself but then I switched to prepared statement as it was getting unmanageable.
I'll try finding a work around whereby I split the query into two parts using the manageable part and the Wilcard search in the statement and the other unmanageable part in the PS.
Else I will again have to attempt that. I had also had a feeling this was affecting it.
Thanks for the help.
If anyone has some solution please post it .
Thank you.
