package org.springframework.jdbc.core;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.SQLException;

One of the three central callback interfaces used by the JdbcTemplate class.
This interface creates a CallableStatement given a connection, provided
by the JdbcTemplate class. Implementations are responsible for providing
SQL and any necessary parameters.
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.
A PreparedStatementCreator should also implement the SqlProvider interface
if it is able to provide the SQL it uses for PreparedStatement creation.
This allows for better contextual information in case of exceptions.
