1、如何用SQL获取一个数据库中的所有表的名称;
SELECT * FROM sysobjects
WHERE xtype='u'

2、如何用SQL获取一个表中所有字段的名称;
SELECT c.name,o.name FROM syscolumns AS c
INNER JOIN sysobjects AS o
ON c.id = o.id

[pbsql]

select name from sysobjects where xtype='U'
select name from syscolumns where id=object_id(N'表明')

[paoluo]

Select Name from sysobjects where Type='U'
Select Name from syscolumns where ID=OBJECT_ID(N'TableName') Order By ColID

[mengzulin]

SELECT dbo.sysobjects.name AS [table], dbo.syscolumns.name AS columns
FROM dbo.sysobjects INNER JOIN
dbo.syscolumns ON dbo.sysobjects.id = dbo.syscolumns.id
WHERE (dbo.sysobjects.xtype = 'u')
