数据字SQL代码的总结

网上有很多SQL SERVER数据库字典的SQL语句，七零八落，我在工作整理了一下思路，总结SQL代码如下。数据库字典包括表结构(分2K和2005）、索引和主键.外键.约束.视图.函数.存储过程.触发器。可以在企业管理器、查询分析器中简单执行，直接了当的查出SQL2K及SQL2005的所有数据字典，方便文档的编写，希望对大家有帮助。

1. SqlServer2000数据库字典--表结构.sql

SELECT TOP 100 PERCENT --a.id,
      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 = si.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 a LEFT OUTER JOIN
      dbo.systypes b ON a.xtype = b.xusertype INNER JOIN
      dbo.sysobjects d ON a.id = d.id AND d.xtype = 'U' AND
      d.status >= 0 LEFT OUTER JOIN
      dbo.syscomments e ON a.cdefault = e.id LEFT OUTER JOIN
      dbo.sysproperties g ON a.id = g.id AND a.colid = g.smallid AND
      g.name = 'MS_Description' LEFT OUTER JOIN
      dbo.sysproperties f ON d.id = f.id AND f.smallid = 0 AND
      f.name = 'MS_Description'
ORDER BY d.name, a.colorder
