package org.springframework.jdbc.core;

import java.sql.PreparedStatement;
import java.sql.SQLException;

Batch update callback interface used by the JdbcTemplate class. 
This interface sets values on a PreparedStatement provided by the JdbcTemplate class, for each of a number of updates in a batch using the same SQL. Implementations are responsible for setting any necessary parameters. SQL with placeholders will already have been supplied. 
Implementations do not need to concern themselves with SQLExceptions
that may be thrown from operations they attempt. The JdbcTemplate class will
catch and handle SQLExceptions appropriately.
