Class SqlUpdater

java.lang.Object
  com.partnersoft.sql.SqlUpdater

public class SqlUpdater
extends java.lang.Object

Tool to simplify basic key-type updates to an SqlTable.

The SQL generated is of the form "update TABLE set WHATNOT=?, NOTWHAT=? where THIS=? and THAT=? and..."; if you want anything more complex you should handle that yourself.

Creates and retains a prepared statement so you can hang onto it and use it over and over on the same connection for better performance.
