Interface PreparedStatementCreator

public interface PreparedStatementCreator

One of the two central callback interfaces used by the JdbcTemplate class. This interface creates a PreparedStatement 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.
