## org.springframework.orm.ibatis
Class SqlMapClientTemplate

    java.lang.Object
      org.springframework.jdbc.support.JdbcAccessor
          org.springframework.orm.ibatis.SqlMapClientTemplate

All Implemented Interfaces:
  InitializingBean, SqlMapClientOperations

    public class SqlMapClientTemplate

extends JdbcAccessor
implements SqlMapClientOperations

Helper class that simplifies data access via the iBATIS `SqlMapClient` API, converting checked SQLExceptions into unchecked DataAccessExceptions, following the `org.springframework.dao` exception hierarchy. Uses the same `SQLExceptionTranslator` mechanism as `JdbcTemplate`.

The main method of this class executes a callback that implements a data access action. Furthermore, this class provides numerous convenience methods that mirror `SqlMapExecutor`'s execution methods.

It is generally recommended to use the convenience methods on this template for plain query/insert/update/delete operations. However, for more complex operations like batch updates, a custom SqlMapClientCallback must be implemented, usually as anonymous inner class. For example:

     getSqlMapClientTemplate().execute(new SqlMapClientCallback() {
             public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {
                     executor.startBatch();
                     executor.update("insertSomething", "myParamValue");
                     executor.update("insertSomethingElse", "myOtherParamValue");
                     executor.executeBatch();
                     return null;
             }
     });

The template needs a SqlMapClient to work on, passed in via the "sqlMapClient" property. A Spring context typically uses a `SqlMapClientFactoryBean` to build the SqlMapClient. The template an additionally be configured with a DataSource for fetching Connections, although this is not necessary if a DataSource is specified for the SqlMapClient itself (typically through SqlMapClientFactoryBean's "dataSource" property).
