生成SQL Server数据字典
1.表信息
Select *
FROM INFORMATION_SCHEMA.COLUMNS
order by Table_name;
select * from INFORMATION_SCHEMA.tables
2.数据字典
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 COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' 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 '√' else '' 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 '√'else '' end) 允许空,
isnull(e.text,'') 默认值,
isnull(g.[value],'') AS 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<>'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.major_id
order by a.id,a.colorder
3.小技巧
Set nocount on
DECLARE @TableName nvarchar(35)
DECLARE Tbls CURSOR
FOR
Select distinct Table_name
FROM INFORMATION_SCHEMA.COLUMNS
--put any exclusions here
--where table_name not like '%old'
order by Table_name
OPEN Tbls
