SQL code

SELECT     表名       = case when a.colorder=1 then d.name else '' end,    表说明     = case when a.colorder=1 then isnull(f.value,'') else '' end,    字段序号   = a.colorder,    字段名     = a.name,    标识       = case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end,    主键       = case when exists(SELECT 1 FROM sysobjects where xtype='PK' and parent_obj=a.id and name in (                     SELECT name FROM sysindexes WHERE indid in(                        SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid))) then '√' else '' end,    类型       = b.name,    占用字节数 = a.length,    长度       = COLUMNPROPERTY(a.id,a.name,'PRECISION'),    小数位数   = isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),    允许空     = case when a.isnullable=1 then '√'else '' end,    默认值     = isnull(e.text,''),    字段说明   = isnull(g.[value],'')FROM     syscolumns aleft join     systypes b on     a.xusertype=b.xusertypeinner join     sysobjects d on     a.id=d.id  and d.xtype='U' and  d.name<>'dtproperties'left join     syscomments e on     a.cdefault=e.idleft join     sysproperties g on     a.id=g.id and a.colid=g.smallid  left join     sysproperties f on     d.id=f.id and f.smallid=0where     d.name='要查询的表'    --如果只查询指定表,加上此条件order by     a.id,a.colorder

上午有人问过

用函数fn_listextendedproperty

如：

SQL code
SELECT     CAST(value AS nvarchar(200)) as tableDescription    FROM fn_listextendedproperty ('MS_Description', 'user', 'dbo', 'table', 'TableName', default, default);SELECT        objname    ,CAST(value AS nvarchar(200)) as fieldDescription    FROM fn_listextendedproperty ('MS_Description', 'user', 'dbo', 'table', @TableName , 'column', default) AS E

SQL code
查询一个表的所有外键SELECT 主键列ID=b.rkey     ,主键列名=(SELECT name FROM syscolumns WHERE colid=b.rkey AND id=b.rkeyid)     ,外键表ID=b.fkeyid     ,外键表名称=object_name(b.fkeyid)     ,外键列ID=b.fkey     ,外键列名=(SELECT name FROM syscolumns WHERE colid=b.fkey AND id=b.fkeyid)     ,级联更新=ObjectProperty(a.id,'CnstIsUpdateCascade')     ,级联删除=ObjectProperty(a.id,'CnstIsDeleteCascade') FROM sysobjects a     join sysforeignkeys b on a.id=b.constid     join sysobjects c on a.parent_obj=c.id where a.xtype='f' AND c.xtype='U'     and object_name(b.rkeyid)='titles'SELECT *FROM information_schema.columnsWHERE TABLE_CATALOG='数据库名'     AND TABLE_NAME = '表名'    AND COLUMN_NAME='列名'select *from syscolumnswhere id=object_id('tableName') and name='fieldName'
