sql基础_一个典型的存储过程

--存储过程

/* =======================
    描    述：在代码中启动事务 创建临时表, 然后在存储过程中处理临时表
             设计了  计数 ,临时表, 快速创建临时表, 插入表的方法, 更新表的方法,字符串格式化 等
    创 建 人：

    说明: 调用本存储过程必须先建临时表 #tmp_TCTdetail ,并存入明细数据

    --1,更新 seq
    UPDATE a
    SET    a.Seq = b.rowno
    FROM   #tmp_TCTdetail a
           INNER JOIN (SELECT row_number() OVER (ORDER BY getdate()) rowno, * FROM #tmp_TCTdetail) b

             AND a.SourceBillTypeID = b.SourceBillTypeID

    --2,更新batchNo
    UPDATE #tmp_TCTdetail
    SET    BatchNo = @CompanyID + right(10000000000 + @MaxBatchNo, 10)

    --3,更新logid
    --3.1 得到主表
    SELECT   Cast('' AS VARCHAR(100)) LogID, WaveBillNo, SourceBillNo, SourceBillTypeID
    INTO     #tmp_TCTmaster
    FROM     #tmp_TCTdetail
    GROUP BY WaveBillNo, SourceBillNo, SourceBillTypeID

    --3.2 更新主表logid
    DECLARE @MaxLogID INT = 0;
    DECLARE @masterCount INT; --主表记录数
    SELECT @masterCount = count(logid) FROM #tmp_TCTmaster;
    EXEC spCRM_GetMaxNum @ComCode = @CompanyID, @ObjID = 'WMS_LoadCarTran', @AddNum = @masterCount, @MaxNum = @MaxLogID OUTPUT

             AND a.SourceBillNo = b.SourceBillNo
             AND a.SourceBillTypeID = b.SourceBillTypeID

    --3.3 插入主表
    INSERT INTO Wms_MaterialLoadCardTranMaster(CompanyID, LogID, BillTypeID, StockID, WaveBillNo, SourceBillNo, SourceBillTypeID,
                  PersonnelID, Operator, ModifyDTM, TaskStatus, Driver, CarCode, TransPers)

             getdate(), '1', '', '', ''

    --3.5 用主表logid 更新 明细表
    UPDATE a
    SET    a.LogID = b.LogID
    FROM   #tmp_TCTdetail a
           INNER JOIN #tmp_TCTmaster b
             ON a.WaveBillNo = b.WaveBillNo
             AND a.SourceBillNo = b.SourceBillNo
             AND a.SourceBillTypeID = b.SourceBillTypeID

    --3.6 插入明细表
    INSERT INTO Wms_MaterialLoadCardTranDetail(CompanyID, LogID, BoxID, BoxCode, Qty, ModifyDTM, Seq, Driver, CarCode, TransPers,
                  BatchNo                      )
      SELECT @CompanyID, LogID, BoxID, BoxCode, Qty, getdate(), Seq, Driver, CarCode, TransPers,
             BatchNo
      FROM   #tmp_TCTdetail

    DROP TABLE #tmp_TCTmaster

    DROP TABLE #tmp_TCTdetail

  --这里获取到 #storerSizeInv 中的  CardID, KindID, ModelID, SeasonID 都是储位的属性,本程序中没有用到
