无法在 SQL 服务器中的 where 条件中调用别名列名

                WHEN '0' THEN Location
                ELSE 'Lite N Lamps'
              END

在这个查询中，我想再添加一个条件，例如

AND LocType = 'Retail Store' 且 TotalHrs=0 但显示错误

列名称"总小时数"无效。

我如何解决这个问题，如果有任何帮助是非常可观的，提前感谢

您可以在以下情况下使用多个 CTE：

WITH cte1
AS (SELECT
  tbl.EmpID,
  CASE
    WHEN MIN(tbl.LeaveTypeId) = 'a' THEN CONVERT(bit, 1)
    ELSE CONVERT(bit, 0)

  CASE
    WHEN (MIN(tbl.LeaveTypeId) IS NOT NULL OR
      MIN(tbl.LeaveTypeId) <> '') THEN MIN(tbl.LeaveDesc)
    ELSE NULL
  END AS 'Leave',
  CASE
    WHEN (MIN(tbl.outime) IS NULL) AND
      (MIN(tbl.LeaveTypeId) IS NULL) THEN CONVERT(bit, 1)
    ELSE CONVERT(bit, 0)
  END AS 'InOut',
  CASE
    WHEN CONVERT(char(5), MIN(tbl.InTime), 108) <> '00:00' THEN MIN(tbl.InTime)
    ELSE NULL
  END AS 'S1IN',
  MIN(tbl.outime) AS 'S1OUT',
  CASE
