Class ParameterizedPreparedStatementCreator

java.lang.Object
  ca.krasnay.sqlbuilder.ParameterizedPreparedStatementCreator

All Implemented Interfaces:

Serializable, Cloneable, org.springframework.jdbc.core.PreparedStatementCreator

public class ParameterizedPreparedStatementCreator
extends Object
implements Cloneable, org.springframework.jdbc.core.PreparedStatementCreator, Serializable

Implementation of Spring's PreparedStatementCreator that allows for the substitution of named parameters. Here's a simple example:

 PreparedStatement ps = new ParameterizedPreparedStatementCreator().setSql(
         "select * from Employee where name like :name").setParameter("name", "Bob%").createPreparedStatement(conn);
 

The implementation performs simple text substitution of parameters, which can lead to problems with things like this: "select * from Employee where name = 'foo:bar'" In this case, createPreparedStatement(Connection) will fail if the bar is not defined, or will result in "select * from Employee where name = 'foo?'", both of which are wrong.
