您好我已经开发了一个存储过程，我在其中声明了一个名为@TEMP_TABLE的表变量，但对于此行
SET @SQL1 = 'UPDATE PO_STAGE set PO_STAGE.ISVALID = ''N''
FROM ERP_ADMIN.'+@STAGE_TABLE+' PO_STAGE, @TEMP_TABLE TMP
where PO_STAGE.ERP_PO_ID = TMP.ERP_POID'
exec (@SQL1)
我收到“必须声明表变量”@TEMP_TABLE“。”错误。 请在这方面帮助我。下面是存储过程的代码。

答案 0 :(得分：1)
您应该将@TEMP_TABLE作为参数传递。要传递 Table 参数，您首先应创建表类型：
IF NOT EXISTS (SELECT 1 FROM sys.types WHERE NAME = 'TEMP_TABLE_TYPE')
CREATE TYPE TEMP_TABLE_TYPE AS TABLE(
ERP_POID nvarchar(50),
ERRORCD nvarchar(50),
ERRORMSG nvarchar(120)
);
并使用它：
exec sp_executesql @Sql, N'@TEMP_TABLE TEMP_TABLE_TYPE readonly', @TEMP_TABLE
对于epxplonation，您可以使用此链接Passing table variable into dynamic sql。
如果您发现这种方式不明显，我建议使用临时表而不是表变量：
CREATE TABLE #TEMP_TABLE (
ERP_POID nvarchar(50),
ERRORCD nvarchar(50),
ERRORMSG nvarchar(120)
);
