sql server递归子节点、父节点sql查询表结构的实例
一、查询当前部门下的所有子部门WITHdept
AS ( SELECT*
FROM dbo.deptTab --部门表
WHEREpid = @id
UNION ALL
SELECTd.*
FROM dbo.deptTab d
INNER JOIN dept ON d.pid = dept.id
)
SELECT *
FROMdept 二、查询当前部门所有上级部门
WITHtab
AS ( SELECTDepId ,
ParentId ,
DepName ,
,
0 AS
FROM deptTab WITH ( NOLOCK ) --表名
WHERE = 1
AND depId = @depId
UNION ALL
SELECTb.DepId ,
b.ParentId ,
b.DepName ,
b. ,
a. + 1
FROM tab a ,
deptTab b WITH ( NOLOCK )
WHEREa.ParentId = b.depId
AND b. = 1
)
SELECT *
FROMtab WITH ( NOLOCK )
WHERE = 1
ORDER BY DESC 三、查询当前表的说明描述
SELECT tbs.name 表名 ,
ds.value 描述
FROMsys.extended_properties ds
LEFT JOIN sysobjects tbs ON ds.major_id = tbs.id
WHEREds.minor_id = 0
AND tbs.name = 'userTab';--表名 四、查询当前表的表结构(字段名、属性、默认值、说明等)
SELECT CASE WHEN col.colorder = 1 THEN obj.name
ELSE ''
END AS 表名 ,
col.colorder AS 序号 ,
col.name AS 列名 ,
ISNULL(ep., '') AS 列说明 ,
t.name AS 数据类型 ,
col.length AS 长度 ,
ISNULL(COLUMNPROPERTY(col.id, col.name, 'Scale'), 0) AS 小数位数 ,
CASE WHEN COLUMNPROPERTY(col.id, col.name, 'IsIdentity') = 1 THEN '√'
ELSE ''
END AS 标识 ,
CASE WHEN EXISTS ( SELECT1
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'
WHEREsc.id = col.id
AND sc.colid = col.colid ) THEN '√'
ELSE ''
END AS 主键 ,
CASE WHEN col.isnullable = 1 THEN '√'
ELSE ''
END AS 允许空 ,
ISNULL(comm.text, '') AS 默认值
FROMdbo.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'
WHEREobj.name = 'userTab'--表名(点此修改)
