Hello Friends,
I want to know the difference between Statement & PreparedStatement.Is there any performance boost in using PreparedStatemnt for STATIC SQL Queries (e.g. SELECT * FROM EMP)compared to Statement?

Thanks in Advance,
Shriniwas

The use of a Statement in JDBC should be 100% localized to being used for DDL (ALTER, CREATE, GRANT, etc) as these are the only statement types that cannot accept BIND VARIABLES.

PreparedStatements or CallableStatements should be used for EVERY OTHER type of statement (DML, Queries). As these are the statement types that accept bind variables.

This is a fact, a rule, a law -- use prepared statements EVERYWHERE. Use
STATEMENTS almost no where.

Yes. The PreparedStatement still gets cached.
