public interface StatementCallback
Generic callback interface for code that operates on a JDBC Statement.
 Allows to execute any number of operations on a single Statement,
 for example a single executeUpdate call or repeated
 executeUpdate calls with varying SQL.
 
Used internally by JdbcTemplate, but also useful for application code.

Object doInStatement(Statement stmt)
                     throws SQLException,
                            DataAccessException
JdbcTemplate.execute with an active JDBC
 Statement. Does not need to care about closing the Statement or the
 Connection, or about handling transactions: this will all be handled
 by Spring's JdbcTemplate.
 NOTE: Any ResultSets opened should be closed in finally blocks
 within the callback implementation. Spring will close the Statement
 object after the callback returned, but this does not necessarily imply
 that the ResultSet resources will be closed: the Statement objects might
 get pooled by the connection pool, with close calls only
 returning the object to the pool but not physically closing the resources.
 
If called without a thread-bound JDBC transaction (initiated by DataSourceTransactionManager), the code will simply get executed on the JDBC connection with its transactional semantics. If JdbcTemplate is configured to use a JTA-aware DataSource, the JDBC connection and thus the callback code will be transactional if a JTA transaction is active.
Allows for returning a result object created within the callback, i.e. a domain object or a collection of domain objects. Note that there's special support for single step actions: see JdbcTemplate.queryForObject etc. A thrown RuntimeException is treated as application exception, it gets propagated to the caller of the template.
stmt - active JDBC Statement
null if none
SQLException - if thrown by a JDBC method, to be auto-converted
 to a DataAccessException by a SQLExceptionTranslator
DataAccessException - in case of custom exceptionsJdbcTemplate.queryForObject(String, Class),
