hi
I've prepared a query with custom date fields. I used prepared
statement and giving data from user.

//in query there is table1.[Date]>=? and table1.[Date]<=? in where
clause.
//database is SQL Server 2000

PreparedStatement pstmt=conn.prepareStatement(query);
pstmt.setDate(1,Date.valueOf("2005-01-01"));
pstmt.setDate(2,Date.valueOf("2005-12-31"));

but it shows following error

So please help me to solve it?
If you tell me how to find the exact error and or tracing the error
then it would be helpful for me.

Hi Manoj. If you're on SQL2000, you will have many fewer headaches
if you switch to the free real type-4 JDBC driver from MS. The
jdbc-odbc
bridge is old, very unreliable, and unsupported.
