SQL Server 关于 Table 字典数据的查询SQL

Posted 2021-01-08 东山絮柳仔

分享一个关于查询SQL Server Table 结构的SQL 语句。

T-SQL 如下：

SELECT (case when a.colorder=1 then d.name else \'\' end) 表名,
a.colorder 字段序号,a.name 字段名,
(case when a.colorder=1 then isnull(f.value,\'\') else \'\' end) 表说明,
(case when COLUMNPROPERTY( a.id,a.name,\'IsIdentity\')=1 then \'1\'else \'0\' end)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 \'1\' else \'0\' end) 主键,b.name 类型,a.length 占用字节数,
COLUMNPROPERTY(a.id,a.name,\'PRECISION\') as 长度,
isnull(COLUMNPROPERTY(a.id,a.name,\'Scale\'),0) as 小数位数,(case when
a.isnullable=1 then \'1\'else \'0\' end) 允许空,
isnull(e.text,\'\') 默认值,isnull(g.[value], \' \') AS [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<>\'dtproperties\'
left join syscomments e on a.cdefault=e.id
left join sys.extended_properties g on a.id=g.major_id AND a.colid=g.minor_id
left join sys.extended_properties f on d.id=f.major_id and f.minor_id=0
--where b.name is not null
WHERE d.name=\'DBA_Server\' --如果只查询指定表,加上此条件，此案例为表DBA_Server
order by a.id,a.colorder

 查询出的结果如下：
