取 SQL SERVER 字段信息

SELECT A.NAME AS '字段',B.NAME AS '类型',A.LENGTH AS '长度',
        CASE WHEN A.ISNULLABLE = 1 THEN 'NULL' ELSE 'NOT NULL' END AS '是否为空'
 FROM SYSOBJECTS AS C 
 LEFT JOIN SYSCOLUMNS AS A ON C.ID = A.ID
 LEFT JOIN SYSTYPES B ON A.XTYPE = B.XTYPE 
     WHERE C.NAME = '所在表名';



Select a.name AS 字段名, b.name AS 类型
FROM syscolumns a INNER JOIN
      systypes b ON a.xusertype = b.xusertype INNER JOIN
      sysobjects d ON a.id = d.id AND d.xtype = 'U' AND d.name <> 'dtproperties'
Where (d.name = '表名')
ORDER BY a.id
