- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
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.
createCallableStatementCreate a callable statement in this connection. Allows implementations to use CallableStatements.
