我正试图遍历一个包含表名列表的TEMP表变量。我想简单地计算每个表中DateTracked列大于30天的行数。我在动态更改from@tblName变量以存储记录计数，然后将其插入到我的跟踪表中时遇到了问题。最后，我将使用游标遍历每个表，但我只想首先为单个表记录这一逻辑。以下是我的测试代码：

DECLARE @tblName as NVARCHAR(MAX)
DECLARE @q as NVARCHAR(MAX)
SET @q = 'Select Count(DateTracked) FROM Audit.' + @tblName + ' WHERE DateTracked > DATEADD(dd, -30, CAST(GETDATE() as date))'

--DECLARE @tblNameTable TABLE
--(
--  tableName NVARCHAR(MAX)
--)
--INSERT INTO @tblNameTable VALUES (N'myTestTable')

DECLARE @ExpectedRecordsToMove AS TABLE (col1 int)
INSERT INTO @ExpectedRecordsToMove EXECUTE sp_executesql @q, N'@tblName nvarchar(500)', @tblName = 'myTestTable'

SELECT * FROM @ExpectedRecordsToMove

推荐答案

找到解决方案。

DECLARE @tblName as NVARCHAR(MAX) = 'tblAutoDispatch_DispatchStatus_Map_Tracking'
DECLARE @q as NVARCHAR(MAX) = 'SELECT Count(DateTracked) FROM Audit.' + @tblName + ' WHERE DateTracked > DATEADD(dd, -30, CAST(GETDATE() as date))'

DECLARE @ExpectedRecordsToMove TABLE
(
    ExpectedRecordsToMove Int
)
INSERT INTO @ExpectedRecordsToMove
EXECUTE sp_executesql @q

SELECT * FROM @ExpectedRecordsToMove
