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）
| 以下为引用的内容： SELECT TOP 100 PERCENT --a.id, CASE WHEN a.colorder = 1 THEN d.name ELSE '' END AS 表名, 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）
| 以下为引用的内容： 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 |
2.SQL Server数据库字典（索引.sql）
| 以下为引用的内容： 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.SQL Server数据库字典（主键.外键.约束.视图.函数.存储过程.触发器.sql）
| 以下为引用的内容： SELECT DISTINCT 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 |
