sql - 尝试将动态 SQL 子查询结果放入 SQL-Server 2008 临时表而不预先定义临时表

Question

我正在尝试将结果放入临时表中，但无法使其正常工作。

DECLARE @query nvarchar(max)
SET @query = N'SELECT * INTO ##TmpTbl FROM (SELECT * FROM Tbl1)'
EXEC(@query)

我做错了什么？

NOTE: I can NOT pre define temp table/table variable because of the actual question being run is a pivot question without pre defined columns in it´s result.

您缺少子查询的别名:

DECLARE @query nvarchar(max)
SET @query = N'SELECT * 
               INTO ##TmpTbl 
               FROM (SELECT * FROM Tbl1) src'  <--- you need an alias
EXEC(@query)
