网上有很多数据库专区 href="http://dev.yesky.com/devsjk" target=_blank>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,只在SQLSERVER2000中测试通过,希望对大家有帮助。
1. SqlServer数据库字典--表结构.sql
以下是引用片段: 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 = 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 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 LEFT OUTER JOIN dbo.sysproperties f ON d.id = f.id AND f.smallid = 0 ORDER BY d.name, a.colorder |
2. SqlServer数据库字典--索引.sql
以下是引用片段: 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. SqlServer数据库字典--主键.外键.约束.视图.函数.存储过程.触发器.sql
以下是引用片段: 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 |

当某些sql因为不知名原因堵塞时,为了不影响后台服务运行,想要给sql增加执行时间限制,超时后就抛异常,保证后台线程不会因为sql堵塞而堵塞。一、yml全局配置单数据源可以,多数据源时会失效二、java配置类配置成功抛出超时异常。importcom.alibaba.druid.pool.DruidDataSource;importcom.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceBuilder;importorg.apache.

0x01前言概述小编又在MySQL中发现了一个Double型数据溢出。当我们拿到MySQL里的函数时,小编比较感兴趣的是其中的数学函数,它们也应该包含一些数据类型来保存数值。所以小编就跑去测试看哪些函数会出现溢出错误。然后小编发现,当传递一个大于709的值时,函数exp()就会引起一个溢出错误。mysql>selectexp(709);+-----------------------+|exp(709)|+-----------------------+|8.218407461554972
