一、查詢當前部門下的所有子部門
WITH dept AS ( SELECT * FROM dbo.deptTab --部門表 WHERE pid = @id UNION ALL SELECT d.* FROM dbo.deptTab d INNER JOIN dept ON d.pid = dept.id ) SELECT * FROM dept
二、查詢當前部門所有上級部門
WITH tab AS ( SELECT DepId , ParentId , DepName , [Enable] , 0 AS [Level] FROM deptTab WITH ( NOLOCK ) --表名 WHERE [Enable] = 1 AND depId = @depId UNION ALL SELECT b.DepId , b.ParentId , b.DepName , b.[Enable] , a.[Level] + 1 FROM tab a , deptTab b WITH ( NOLOCK ) WHERE a.ParentId = b.depId AND b.[enable] = 1 ) SELECT * FROM tab WITH ( NOLOCK ) WHERE [enable] = 1 ORDER BY [level] DESC
三、查詢當前表的說明描述
SELECT tbs.name 表名 , ds.value 描述 FROM sys.extended_properties ds LEFT JOIN sysobjects tbs ON ds.major_id = tbs.id WHERE ds.minor_id = 0 AND tbs.name = 'userTab';--表名
四、查詢當前表的表結構(字段名、屬性、默認值、說明等)
SELECT CASE WHEN col.colorder = 1 THEN obj.name ELSE '' END AS 表名 , col.colorder AS 序號 , col.name AS 列名 , ISNULL(ep.[value], '') AS 列說明 , t.name AS 數據類型 , col.length AS 長度 , ISNULL(COLUMNPROPERTY(col.id, col.name, 'Scale'), 0) AS 小數位數 , CASE WHEN COLUMNPROPERTY(col.id, col.name, 'IsIdentity') = 1 THEN '√' ELSE '' END AS 標識 , CASE WHEN EXISTS ( SELECT 1 FROM dbo.sysindexes si INNER JOIN dbo.sysindexkeys sik ON si.id = sik.id AND si.indid = sik.indid INNER JOIN dbo.syscolumns sc ON sc.id = sik.id AND sc.colid = sik.colid INNER JOIN dbo.sysobjects so ON so.name = si.name AND so.xtype = 'PK' WHERE sc.id = col.id AND sc.colid = col.colid ) THEN '√' ELSE '' END AS 主鍵 , CASE WHEN col.isnullable = 1 THEN '√' ELSE '' END AS 允許空 , ISNULL(comm.text, '') AS 默認值 FROM dbo.syscolumns col LEFT JOIN dbo.systypes t ON col.xtype = t.xusertype INNER JOIN dbo.sysobjects obj ON col.id = obj.id AND obj.xtype = 'U' AND obj.status >= 0 LEFT JOIN dbo.syscomments comm ON col.cdefault = comm.id LEFT JOIN sys.extended_properties ep ON col.id = ep.major_id AND col.colid = ep.minor_id AND ep.name = 'MS_Description' LEFT JOIN sys.extended_properties epTwo ON obj.id = epTwo.major_id AND epTwo.minor_id = 0 AND epTwo.name = 'MS_Description' WHERE obj.name = 'userTab'--表名(點此修改) ORDER BY col.colorder;
