java : use of executeQuery(string) method not supported error?

Question

I\'m doing a simple preparedstatement query execution and its throwing me this error: java.sql.SQLException: Use of the executeQuery(string) method is not supported on this

Answer 1

A couple of things are worth checking:

1. Use a different alias. Using COUNT as an alias would be asking for trouble.
2. The query object need not be passed twice, once during preparation of the statement and later during execution. Using it in con.prepareStatement(query); i.e. statement preparation, is enough.

ADDENDUM

It's doubtful that jTDS supports usage of the String arg method for PreparedStatement. The rationale is that PreparedStatement.executeQuery() appears to be implemented, whereas Statement.executeQuery(String) appears to have been overriden in PreparedStatement.executeQuery() to throw the stated exception.
