Question

我有这个查询

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

结果如下：

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

我想在此结果中运行所有选择查询。我怎么能这样做？

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

我把它解决了，记得在GRANT之前有一个空格。

    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

如何运行一组选择查询？
