如何运行一组选择查询？

Question

我有这个疑问

SELECT 'GRANT SELECT ON ' + TABLE_NAME + ' TO '+ @UserName 
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_TYPE = 'BASE TABLE' AND 
TABLE_NAME LIKE 'aspnet%' 

和结果是这样的：

GRANT SELECT ON aspnet_Applications TO user04 
GRANT SELECT ON aspnet_Membership TO user04 
GRANT SELECT ON aspnet_Paths TO user04 
GRANT SELECT ON aspnet_PersonalizationAllUsers TO user04 
GRANT SELECT ON aspnet_PersonalizationPerUser TO user04 
GRANT SELECT ON aspnet_Profile TO user04 
GRANT SELECT ON aspnet_Roles TO user04 
GRANT SELECT ON aspnet_SchemaVersions TO user04 

我想运行的所有选择查询的这个结果。我怎样才能做到这一点？

Answer 1

DECLARE @Sql NVARCHAR(MAX) 
SET @Sql = '' 

SELECT @Sql = @Sql + 'GRANT SELECT ON ' + TABLE_NAME + ' TO '+ @UserName + ' 
' -- Newline to keep statements from being just one long line. 
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_TYPE = 'BASE TABLE' AND 
TABLE_NAME LIKE 'aspnet%' 

-- Print it first to double-check that it looks right before running. 
PRINT @Sql 

-- After you've validated it with print, run it. 
EXEC sp_executeSql @Sql 

Answer 2

我知道了，记得在GRANT之前有个空格。

DECLARE @Sql NVARCHAR(MAX) 
SET @Sql = '' 
SELECT @Sql =@Sql + ' GRANT SELECT ON ' + TABLE_NAME + ' TO '+ @UserName +'' 
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_TYPE = 'BASE TABLE' AND 
TABLE_NAME LIKE 'aspnet%' 
PRINT @Sql 
EXEC sp_executeSql @Sql
