  本文主要介绍了三个实用的SQL Server数据库字典SQL语句,数据库字典主要包括表结构(分为SQL Server 2000和SQL Server 2005)、索引和主键. 外键.约束.视图.函数.存储过程.触发器。你可以在查询分析器、企业管理器中简单执行后,快速的查出SQL Server 2000及SQL Server 2005的全部数据字典。

  1. SQL Server 2000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

  ◆SQL Server 2005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
