createStatement() creates a Statement Object based on a fully qualified SQL String without parameters. prepareStatement() creates a PreparedStatement Object out of a parameterized SQL String. The use of prepareState has some additional overhead in the database the first time it is run. So, if you only need to run the statement once or twice for your application, createStatement is the best way to handle it. Addtionally if the components of your where clause are dynamic (ie you may add an additional qualifier to the where clause based on user input) you need to use the create statement. However since the PreparedStatement Object gets compiled in the database, it will provide you with better performance if you need to repeatedly call the SQL and only change the values in the where clause. Note: if you are always calling the same SQL you'll get the best performance converting it into an SQL Stored Procedure and calling it using the CallableStatement Object.
