提取数据库内所有表的字段详细说明的SQL语句
为什么“字段说明”读不出数据呀？
SQL code:
SELECT (CASE WHEN a.colorder = 1 THEN d .name ELSE '' END) N'表名',
a.colorder N'字段序号', a.name N'字段名', (CASE WHEN COLUMNPROPERTY(a.id,
a.name, 'IsIdentity') = 1 THEN '√' ELSE '' END) N'标识', (CASE WHEN
(SELECT COUNT(*)
from sysobjects
WHERE (name IN
(SELECT name
from sysindexes
WHERE (id = a.id) AND (indid IN
(SELECT indid
from sysindexkeys
WHERE (id = a.id) AND (colid IN
(SELECT colid
from syscolumns
WHERE (id = a.id) AND (name = a.name))))))) AND
(xtype = 'PK')) > 0 THEN '√' ELSE '' END) N'主键', b.name N'类型',
a.length N'占用字节数', COLUMNPROPERTY(a.id, a.name, 'PRECISION') AS N'长度',
isnull(COLUMNPROPERTY(a.id, a.name, 'Scale'), 0) AS N'小数位数',
(CASE WHEN a.isnullable = 1 THEN '√' ELSE '' END) N'允许空', isnull(e.text, '')
N'默认值', isnull(g.[value], '') AS N'字段说明'
from syscolumns a LEFT JOIN
systypes b ON a.xtype = b.xusertype INNER JOIN
sysobjects d ON a.id = d .id AND d .xtype = 'U' AND d .name <> 'dtproperti
