Interface NamedParameterJdbcOperations

All Known Implementing Classes:

NamedParameterJdbcTemplate

public interface NamedParameterJdbcOperations

Interface specifying a basic set of JDBC operations allowing the use of named parameters rather than the traditional '?' placeholders.

This is an alternative to the classic JdbcOperations interface, implemented by NamedParameterJdbcTemplate. This interface is not often used directly, but provides a useful option to enhance testability, as it can easily be mocked or stubbed.

Since:

2.0

Method Detail

getJdbcOperations

JdbcOperations getJdbcOperations()

Expose the classic Spring JdbcTemplate to allow invocation of classic JDBC operations.

execute

              SqlParameterSource paramSource,
              PreparedStatementCallback<T> action)
          throws DataAccessException

Execute a JDBC data access operation, implemented as callback action working on a JDBC PreparedStatement. This allows for implementing arbitrary data access operations on a single Statement, within Spring's managed JDBC environment: that is, participating in Spring-managed transactions and converting JDBC SQLExceptions into Spring's DataAccessException hierarchy.

The callback action can return a result object, for example a domain object or a collection of domain objects.

Parameters:

sql - SQL to execute

paramSource - container of arguments to bind to the query

action - callback object that specifies the action

Returns:

a result object returned by the action, or null

Throws:

DataAccessException - if there is any problem
