SQL Server中授予用户查看对象定义的权限
在SQL Server中，有时候需要给一些登录名（用户）授予查看所有或部分对象（存储过程、函数、视图、表）的定义权限存。如果是部分存储过程、函数、视图授予查看定义的权限，那么就像下面脚本所示，比较繁琐：
GRANT VIEW DEFINITION ON YOUR_PROCEDURE TO USERNAME;
GRANT VIEW DEFINITION ON YOUR_FUNCTION TO USERNAME;
GRANT VIEW DEFINITION ON YOUR_VIEW TO USERANEM;
.....................................................
如果是批量授权，那么可以使用下面脚本生成授权脚本。然后执行生成的脚本：
USE DatabaseName;
GO
---给用户授予查看存储过程定义的权限
DECLARE @loginname VARCHAR(32);
SET @loginname='[eopms_reader]'
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) + '.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.procedures;
--给用户授予查看自定义函数定义的权限
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) + '.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.objects
WHERE type_desc IN ( 'SQL_SCALAR_FUNCTION', 'SQL_TABLE_VALUED_FUNCTION',
'AGGREGATE_FUNCTION' );
--给用户授予查看视图定义的权限
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) + '.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.views;
--给用户授予查看视表定义的权限
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id)
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.tables;
如果你想直接执行脚本，不想生成授权脚本，那么可以使用下面脚本实现授权。当然前提是你选择所要授权的数据库（USE DatabaseName)
DECLARE @loginname VARCHAR(32);
DECLARE @sqlcmd NVARCHAR(MAX);
DECLARE @name sysname;
DECLARE @schema_id INT;
SET @loginname='[kerry]'
DECLARE procedure_cursor CURSOR FORWARD_ONLY
FOR
SELECT schema_id, name
FROM sys.procedures;
OPEN procedure_cursor;
FETCH NEXT FROM procedure_cursor INTO @schema_id, @name;
---给用户授予查看存储过程定义的权限
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sqlcmd= 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(@schema_id) + '.'
+ QUOTENAME(@name) + ' TO ' + @loginname + ';'
--PRINT @sqlcmd;
EXEC sp_executesql @sqlcmd;
FETCH NEXT FROM procedure_cursor INTO @schema_id, @name;
END
CLOSE procedure_cursor;
DEALLOCATE procedure_cursor;
DECLARE function_cursor CURSOR FAST_FORWARD
FOR
SELECT schema_id, name
FROM sys.objects
WHERE type_desc IN ( 'SQL_SCALAR_FUNCTION', 'SQL_TABLE_VALUED_FUNCTION',
'AGGREGATE_FUNCTION' );
--给用户授予查看自定义函数定义的权限
OPEN function_cursor;
FETCH NEXT FROM function_cursor INTO @schema_id,@name;
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sqlcmd= 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(@schema_id) + '.'
+ QUOTENAME(@name) + ' TO ' + @loginname + ';'
--PRINT @sqlcmd;
EXEC sp_executesql @sqlcmd;
FETCH NEXT FROM function_cursor INTO @schema_id, @name;
END
CLOSE function_cursor;
DEALLOCATE function_cursor;
DECLARE view_cursor CURSOR FAST_FORWARD
FOR
SELECT schema_id, name FROM sys.views;
OPEN view_cursor;
FETCH NEXT FROM view_cursor INTO @schema_id, @name;
WHILE @@FETCH_STATUS = 0
BEGIN
--给用户授予查看视图定义的权限
SET @sqlcmd= 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(@schema_id) + '.'
+ QUOTENAME(@name) + ' TO ' + @loginname + ';'
--PRINT @sqlcmd;
EXEC sys.sp_executesql @sqlcmd;
FETCH NEXT FROM view_cursor INTO @schema_id, @name;
END
CLOSE view_cursor;
DEALLOCATE view_cursor;
DECLARE table_cursor CURSOR FAST_FORWARD
FOR
SELECT schema_id,name FROM sys.tables;
OPEN table_cursor;
FETCH NEXT FROM table_cursor INTO @schema_id, @name;
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sqlcmd ='GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(@schema_id) + '.'
+ QUOTENAME(@name) + ' TO ' + @loginname + ';'
--PRINT @sqlcmd;
EXEC sys.sp_executesql @sqlcmd;
FETCH NEXT FROM table_cursor INTO @schema_id, @name;
END
CLOSE table_cursor;
DEALLOCATE table_cursor;
如果单个用户授权，那么使用上面方法已经OK，但是一个系统，经常遇到这种授权情况，那么使用上面方法也会变得非常繁琐；另外，当新增表、视图、存储过程后，又需要修改相关授权脚本，这样变得非常麻烦繁琐，那么可以创建一个数据库角色，授予查看数据库对象定义的权限，然后新建登录名时，将这个数据库角色授予新建的登录名即可。这样以后即使有权限啥变化，只需要调整数据库角色的权限即可，不需修改登录名。对于重复性的授权工作会变得非常方便、简单。例如，需要给新建的登录名kerry授予查看数据库对象定义的权限，那么首先创建数据库角色View_Definiton，然后将查看定义的权限授予数据库角色View_Definiton，最后，创建了登录名kerry后，只需将角色View_Definiton授予kerry即可。
USE AdventureWorks2014;
GO
CREATE ROLE [View_Definiton] AUTHORIZATION [dbo]
GO
DECLARE @loginname VARCHAR(32);
SET @loginname='View_Definiton'
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) + '.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.procedures;
--给用户授予查看自定义函数定义的权限
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) + '.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.objects
WHERE type_desc IN ( 'SQL_SCALAR_FUNCTION', 'SQL_TABLE_VALUED_FUNCTION',
'AGGREGATE_FUNCTION' );
--给用户授予查看视图定义的权限
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) + '.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.views;
--给用户授予查看视表定义的权限
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) +'.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.tables;
ALTER ROLE [View_Definiton] ADD MEMBER [kerry]
GO
