导读：1.查询当前数据库所有表 复制代码 代码如下: SELECT O.object_id AS TableId, TableName=O.name , TableDesc= O.type FROM sys.columns C INNER JOIN sys.objects O ON C.[object_id]=O.[object_id] AND O.type=U AND O.is_ms_shipped=0 INNER JOIN sys.type

1.查询当前数据库所有表 复制代码 代码如下: SELECT O.object_id AS TableId, TableName=O.name , TableDesc= O.type FROM sys.columns C INNER JOIN sys.objects O ON C.[object_id]=O.[object_id] AND O.type='U' AND O.is_ms_shipped=0 INNER JOIN sys.types T ON C.user_type_id=T.user_type_id LEFT JOIN sys.extended_properties PTB ON PTB.class=1 AND PTB.minor_id=0 AND C.[object_id]=PTB.major_id WHERE C.column_id=1 ORDER BY TableName 2.查询当前表所有字段，数据，约束 复制代码 代码如下: select tabName=O.NAME, columnLine=C.column_id, columnName=C.name, typeNum=T.name, typeLength=C.max_length, fState=ISNULL(G.value,N''), isAbleNull=CASE WHEN C.is_nullable=1 THEN N'√'ELSE N'' END, defaultData=ISNULL(D.definition,N''), isIdentity=CASE WHEN C.is_identity=1 THEN N'√'ELSE N'' END, isPrimary=case when exists(SELECT 1 FROM sysobjects where xtype='PK' and parent_obj=c.[object_id] and name in ( SELECT name FROM sysindexes WHERE indid in( SELECT indid FROM sysindexkeys WHERE id = c.[object_id] AND colid=c.column_id))) then '√' else '' end, isForeign=case when exists(select * from sysforeignkeys fk where C.[object_id]=FK.fkeyid AND C.column_id=FK.fkey)then '√' else '' end, TabForeignName=ISNULL(IDX.FKName,N''), OutNameCol=ISNULL(IDX.ns,N'') FROM sys.columns C INNER JOIN sys.objects O ON C.[object_id]=O.[object_id] AND O.type='U' AND O.is_ms_shipped=0 INNER JOIN sys.types T ON C.user_type_id=T.user_type_id left JOIN sys.extended_properties G ON C.[object_id]=G.major_id and c.column_id=g.minor_id LEFT JOIN sys.default_constraints D ON C.[object_id]=D.parent_object_id AND C.column_id=D.parent_column_id AND C.default_object_id=D.[object_id] left join sysforeignkeys fk on C.[object_id]=FK.fkeyid and C.column_id=FK.fkey LEFT JOIN -- 索引及主键信息 ( SELECT IDX.fkeyid, IDX.fkey, FKName=o.name, ns=ss.name FROM sysforeignkeys IDX INNER JOIN sys.objects O ON IDX.rkeyid=O.[object_id] AND O.type='U' AND O.is_ms_shipped=0 left join syscolumns ss on IDX.rkeyid=ss.id and IDX.RKEY=SS.COLID )IDX ON C.[object_id]=IDX.fkeyid AND C.column_id=IDX.fkey WHERE O.name=N'{0}' ------要查询的表名 ORDER BY O.name,C.column_id 3.字段 要加单引号varchar,char,nvarchar,nchar,text,ntext,datetime 不需要加int,numeric,bit 不需要加 带长度：[binary],[char],[decimal],[nchar],[numeric],[nvarchar],[varbinary][varchar] 不用带：[bigint],[bit],[datetime],[float],[image],[int],[xml],[timestamp],[tinyint], [uniqueidentifier],[money],[ntext],[real],[smalldatetime],[smallint],[smallmoney], [sql_variant],[text]  （编辑：济南站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
