有办法抓到数据库的所有表的列名和属性吗？

[gopark]

抓出来的格式如下

可能sysobjects,syscolumns就差不多可以顯示屬性了

[playwarcraft]

--簡單一點,這樣就可以表示個大概了
select A.[name] as table_name,B.[name] as column_name,C.[name] as type from sysobjects A
inner join syscolumns B on A.[id]=B.[id]
inner join systypes C on B.xtype=C.xtype

用这个存储过程就OK了

CREATE FUNCTION dbo.fnTableColumnAllInfo
(@sTableName varchar(128))
RETURNS TABLE
AS
RETURN
SELECT
b.*,a.*
from dbo.fnTableColumnInfo(@sTableName) a,TableDescription b
where a.sColumnName = b.ColumnName
and b.TableName = @sTableName

[boby168]

Sorry，还有一个

CREATE FUNCTION dbo.fnTableColumnInfo
(@sTableName varchar(128))
RETURNS TABLE
AS
RETURN
SELECT c.name AS sColumnName,
c.colid AS nColumnID,
dbo.fnIsColumnPrimaryKey(@sTableName, c.name) AS bPrimaryKeyColumn,
CASE WHEN t.name IN ('char', 'varchar', 'binary', 'varbinary', 'nchar', 'nvarchar') THEN 1
WHEN t.name IN ('decimal', 'numeric') THEN 2
ELSE 0
END AS nAlternateType,
c.length AS nColumnLength,
c.prec AS nColumnPrecision,
c.scale AS nColumnScale,
c.IsNullable,
SIGN(c.status & 128) AS IsIdentity,
t.name as sTypeName
--dbo.fnGetColumnDescription(@sTableName,c.name) AS ColumnDesc,
/*
a.ColumnPreDesc,
a.ColumnPostDesc,
a.DefaultValue,
a.LevelRelation,
a.ForeignKey,
a.ControlOrder,
a.PageNumber
*/
FROM syscolumns c
INNER JOIN systypes t ON c.xtype = t.xtype and c.usertype = t.usertype
/*Left JOIN TableDescription a ON a.TableName = @sTableName and a.ColumnName = @sTableName*/

WHERE c.id = OBJECT_ID(@sTableName)
