将查询评估为行中的字符串

Say I have a table where each row is a query in a string representation

假设我有一个表，其中每一行都是字符串表示形式的查询

'select * from foo1'

'select * from foo1'

'select * from foo2'

'select * from foo2'

'select * from foo3'

'select * from foo3'

Is it possible to evaluate all the queries at once?

是否可以一次评估所有查询？

Change QueryString and TableName in the code below to reflect your table info. Nothing else needs to be changed.

在下面的代码中更改QueryString和TableName以反映您的表信息。没有别的东西需要改变。

DECLARE @Query varchar(50);  

DECLARE query_cursor CURSOR FOR
SELECT QueryString FROM TableName;

OPEN query_cursor;

FETCH NEXT FROM query_cursor
INTO @Query;

WHILE @@FETCH_STATUS = 0
BEGIN
   EXEC (@Query);
   FETCH NEXT FROM query_cursor
   INTO @Query;
END

CLOSE query_cursor;
DEALLOCATE query_cursor;
