The Prepared Statement is a slightly more powerful version of a Statement, and should always be at least as quick and easy to handle as a Statement.
The Prepared Stateme
As Quoted by mattjames
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.
