在SQL Server中，有時候需要給一些登錄名（用戶）授予查看所有或部分對象（存儲過程、函數、視圖、表）的定義權限存。如果是部分存儲過程、函數、視圖授予查看定義的權限，那么就像下面腳本所示，比較繁瑣：
GRANT VIEW DEFINITION ON YOUR_PROCEDURE TO USERNAME;
GRANT VIEW DEFINITION ON YOUR_FUNCTION TO USERNAME;
GRANT VIEW DEFINITION ON YOUR_VIEW TO USERANEM;
.....................................................
如果是批量授權，那么可以使用下面腳本生成授權腳本。然后執行生成的腳本：
USE DatabaseName;
GO
---給用戶授予查看存儲過程定義的權限
DECLARE @loginname VARCHAR(32);
SET @loginname='[eopms_reader]'
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) + '.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.procedures;
--給用戶授予查看自定義函數定義的權限
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' );
--給用戶授予查看視圖定義的權限
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id) + '.'
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.views;
--給用戶授予查看視表定義的權限
SELECT 'GRANT VIEW DEFINITION ON ' + SCHEMA_NAME(schema_id)
+ QUOTENAME(name) + ' TO ' + @loginname + ';'
FROM sys.tables;
如果你想直接執行腳本，不想生成授權腳本，那么可以使用下面腳本實現授權。當然前提是你選擇所要授權的數據庫（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;
---給用戶授予查看存儲過程定義的權限
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' );
--給用戶授予查看自定義函數定義的權限
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
--給用戶授予查看視圖定義的權限
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;
如果單個用戶授權，那么使用上面方法已經OK，但是一個系統，經常遇到這種授權情況，那么使用上面方法也會變得非常繁瑣；另外，當新增表、視圖、存儲過程后，又需要修改相關授權腳本，這樣變得非常麻煩繁瑣，那么可以創建一個數據庫角色，授予查看數據庫對象定義的權限，然后新建登錄名時，將這個數據庫角色授予新建的登錄名即可。這樣以后即使有權限啥變化，只需要調整數據庫角色的權限即可，不需修改登錄名。對於重復性的授權工作會變得非常方便、簡單。例如，需要給新建的登錄名kerry授予查看數據庫對象定義的權限，那么首先創建數據庫角色View_Definiton，然后將查看定義的權限授予數據庫角色View_Definiton，最后，創建了登錄名kerry后，只需將角色View_Definiton授予kerry即可。
