Re: how to Escape single quotes with PreparedStatment

I think you're defining the "?" parameter incorrectly for the PreparedStatement.

Try this instead:-

String query="SELECT count(*) over () as ROWCOUNT,
CONSUMER_ID,WENEXA_ID,CONSUMER_NAME,CONTACT_NO,residing_village from
db_consumer WHERE lower(CONSUMER_NAME) LIKE (lower(?))";

query.setString(1,"%Fred%");

Where "Fred" is the string you're searching for.

You cannot use the ? token to substitute part of data value, only a whole value. As you are parameterizing the
"pattern"argument to the LIKE expression which is a String argument, you must pass the complete pattern as a String
parameter.

Hope this helps,
Andrew
