事務控制

示例：

// move data from temp_table to work_tabletry {sqlMapClient.startTransaction();T03SlipWk orderForm = (T03SlipWk) session.get( "SLIP_WK" );moveOrderFormToWorkTable( orderForm.getSlipId() );moveProductsToWorkTable( orderForm.getSlipId() );deleteProductsInTempTable( orderForm.getSlipId() );deleteOrderFormInTempTable( orderForm.getSlipId() );sqlMapClient.commitTransaction();}catch( SQLException e){LOG.error( e );return ERROR;}finally{sqlMapClient.endTransaction();}// delete datas from T03 by slipIdvoid deleteOrderFormInTempTable( String slipId ) throws SQLException {assert slipId != null;T03SlipWkDAO dao = new T03SlipWkDAOImpl( sqlMapClient );T03SlipWkExample example = new T03SlipWkExample();T03SlipWkExample.Criteria criteria = example.createCriteria();criteria.andSlipIdEqualTo( slipId );dao.deleteByExample( example );}// delete datas from T04 by slipIdvoid deleteProductsInTempTable( String slipId ) throws SQLException {assert slipId != null;T04CaseDtlWkDAO dao = new T04CaseDtlWkDAOImpl( sqlMapClient );T04CaseDtlWkExample example = new T04CaseDtlWkExample();T04CaseDtlWkExample.Criteria criteria = example.createCriteria();criteria.andSlipIdEqualTo( slipId );dao.deleteByExample( example );}// Move datas from T04 to T06 by slipIdvoid moveProductsToWorkTable( String slipId ) throws SQLException {assert slipId != null;T06CaseDtlTrnDAO dao = new T06CaseDtlTrnDAOImpl( sqlMapClient );dao.insertFromT04( slipId );}// Move datas from T03 to T05 by slipIdvoid moveOrderFormToWorkTable( String slipId ) throws SQLException {assert slipId != null;T05SlipTrnDAO dao = new T05SlipTrnDAOImpl( sqlMapClient );dao.insertFromT03( slipId );//used for test transication//throw new SQLException("tttttttttttt");}

四條單獨的SQL 語句操作：

moveOrderFormToWorkTable( orderForm.getSlipId() );
moveProductsToWorkTable( orderForm.getSlipId() );
deleteProductsInTempTable( orderForm.getSlipId() );
deleteOrderFormInTempTable( orderForm.getSlipId() );

要么都成功，要么都失敗！實踐證明，上面的事務控制成功！

位置：BPP /?jp.co.snjp.kddi.ht.action.CheckResultAction.checkComplete()

兩表操作將SQL語句寫入單表

如：moveOrderFormToWorkTable( orderForm.getSlipId() ) 就是 insert ?into ... select ...

則只需要配置， insert ?操作對應的表（t05_slip_trn_SqlMap.xml）。

<!-- add by GongQiang,將數據從T03轉到T05 --><insert id="insert_from_t03" parameterClass="java.lang.String" >INSERT INTO T05_SLIP_TRN(SLIP_ID,BARCODE,COMP_CD1,COMP_NM1,COMP_NM2,COMP_NM3,SHP_DATE1,SLIP_NUM1,SLIP_DTL_NUM1,PROD_CD1,PROD_NM1,LOT1,SHP_VOL1,FUNC_ID,USR_ID,USR_GRP,WK_REG_DATE,REG_DATE,UPDATE) SELECT SLIP_ID,BARCODE,COMP_CD1,COMP_NM1,COMP_NM2,COMP_NM3,SHP_DATE1,SLIP_NUM1,SLIP_DTL_NUM1,PROD_CD1,PROD_NM1,LOT1,SHP_VOL1,FUNC_ID,USR_ID,USR_GRP,REG_DATE,REG_DATE,UPDATE FROM T03_SLIP_WK WHERE SLIP_ID = #SLIP_ID:VARCHAR#</insert>然后再對應的 dao （T05SlipTrnDAOImpl）中添加方法：

// add by GongQiang,將數據從T03轉到T05 public void insertFromT03( String slipId ) throws SQLException{sqlMapClient.insert("t05_slip_trn.insert_from_t03", slipId );}
