SQLException: Exhausted Resultset

Question

I have a problem with my JDBC code. This is the relevant code:

/** method for checking password into the Oracle database */
public String CheckUserDB(String          


        

Answer 1

use the varchar data type instead of char in the oracle database.

if you use char then actual size with blank space of database is compared with query parameter

and query doesnt get exucuted that is result gets false.

So use the varchar datatype in oracle database.
