SQL Server元数据导出-优快云博客

1 导表的:

SELECT TOP (100) PERCENT
CASE WHEN a.colorder = 1 THEN d .name ELSE '' END AS 表名,
CASE WHEN a.colorder = 1 THEN isnull(f.value, '')ELSE '' END AS 表说明,
a.colorder AS 字段序号,
a.name AS 字段名,
CASE WHEN COLUMNPROPERTY(a.id, a.name, 'IsIdentity')= 1 THEN '√' ELSE '' END AS 标识,
CASE WHEN EXISTS(SELECT 1 FROM dbo.sysindexes si INNER JOIN dbo.sysindexkeys sik ON si.id = sik.id AND si.indid = sik.indid
             INNER JOIN dbo.syscolumns sc ON sc.id = sik.id AND sc.colid = sik.colid
             INNER JOIN dbo.sysobjects so ON so.name = so.name AND so.xtype = 'PK'
     WHERE sc.id = a.id AND sc.colid = a.colid) THEN '√' ELSE '' END AS 主键,
b.name AS 类型,
a.length AS 长度,
COLUMNPROPERTY(a.id, a.name,'PRECISION') AS 精度,
ISNULL(COLUMNPROPERTY(a.id, a.name, 'Scale'), 0) AS 小数位数,
CASE WHEN a.isnullable = 1 THEN '√' ELSE '' END AS 允许空,
ISNULL(e.text, '') AS 默认值,
ISNULL(g.value, '') AS 字段说明,
d.crdate AS 创建时间,
CASE WHEN a.colorder = 1 THEN d .refdate ELSE NULL END AS 更改时间
FROM dbo.syscolumns AS a LEFT OUTER JOIN
dbo.systypes AS b ON a.xtype = b.xusertype INNER JOIN
dbo.sysobjects AS d ON a.id = d.id AND d.xtype = 'U' AND d.status >= 0 LEFT OUTER JOIN
dbo.syscomments AS e ON a.cdefault = e.id LEFT OUTER JOIN
sys.extended_properties AS g ON a.id = g.major_id AND a.colid = g.minor_id LEFT OUTER JOIN
sys.extended_properties AS f ON d.id = f.major_id AND f.minor_id = 0
ORDER BY d.name, 字段序号

2\导索引的
SELECT TOP 100 PERCENT --a.id,
CASE WHEN b.keyno = 1 THEN c.name ELSE '' END AS 表名,
CASE WHEN b.keyno = 1 THEN a.name ELSE '' END AS 索引名称,
d.name AS 列名,
b.keyno AS 索引顺序,
CASE indexkey_property(c.id, b.indid, b.keyno, 'isdescending') WHEN 1 THEN '降序' WHEN 0 THEN '升序' END AS 排序,
CASE WHEN p.id IS NULL THEN '' ELSE '√' END AS 主键,
CASE INDEXPROPERTY(c.id, a.name, 'IsClustered')WHEN 1 THEN '√' WHEN 0 THEN '' END AS 聚集,
CASE INDEXPROPERTY(c.id,a.name, 'IsUnique') WHEN 1 THEN '√' WHEN 0 THEN '' END AS 唯一,
CASE WHEN e.id IS NULL THEN '' ELSE '√' END AS 唯一约束,
a.OrigFillFactor AS 填充因子,
c.crdate AS 创建时间,
c.refdate AS 更改时间
FROM dbo.sysindexes a INNER JOIN
dbo.sysindexkeys b ON a.id = b.id AND a.indid = b.indid INNER JOIN
dbo.syscolumns d ON b.id = d.id AND b.colid = d.colid INNER JOIN
dbo.sysobjects c ON a.id = c.id AND c.xtype = 'U' LEFT OUTER JOIN
dbo.sysobjects e ON e.name = a.name AND e.xtype = 'UQ' LEFT OUTER JOIN
dbo.sysobjects p ON p.name = a.name AND p.xtype = 'PK'
WHERE (OBJECTPROPERTY(a.id, N'IsUserTable') = 1) AND (OBJECTPROPERTY(a.id,
N'IsMSShipped') = 0) AND (INDEXPROPERTY(a.id, a.name, 'IsAutoStatistics') = 0)
ORDER BY c.name, a.name, b.keyno

------------------------------------------------------------------------

3\导出主\外键\约束\试图等对象
SELECT DISTINCT
TOP 100 PERCENT o.xtype,
CASE o.xtype WHEN 'X' THEN '扩展存储过程' WHEN 'TR' THEN '触发器' WHEN 'PK' THEN
'主键' WHEN 'F' THEN '外键' WHEN 'C' THEN '约束' WHEN 'V' THEN '视图' WHEN 'FN'
THEN '函数-标量' WHEN 'IF' THEN '函数-内嵌' WHEN 'TF' THEN '函数-表值' ELSE '存储过程'
END AS 类型, o.name AS 对象名, o.crdate AS 创建时间, o.refdate AS 更改时间,
c.text AS 声明语句
FROM dbo.sysobjects o LEFT OUTER JOIN
dbo.syscomments c ON o.id = c.id
WHERE (o.xtype IN ('X', 'TR', 'C', 'V', 'F', 'IF', 'TF', 'FN', 'P', 'PK')) AND
(OBJECTPROPERTY(o.id, N'IsMSShipped') = 0)
ORDER BY CASE o.xtype WHEN 'X' THEN '扩展存储过程' WHEN 'TR' THEN '触发器' WHEN
'PK' THEN '主键' WHEN 'F' THEN '外键' WHEN 'C' THEN '约束' WHEN 'V' THEN '视图'
WHEN 'FN' THEN '函数-标量' WHEN 'IF' THEN '函数-内嵌' WHEN 'TF' THEN '函数-表值'
ELSE '存储过程' END DESC

这是3个都是导出这个库中的相应对象,如果想导出单个表的,需要你自己修改一下
希望对你有帮助
