很多朋友都对“SQL Server如何对特定对象搜索，SQL语句是什么”的内容比较感兴趣，对此小编整理了相关的知识分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获，那么感兴趣的朋友就继续往下看吧！ 检索数据库架构信息 - ADO.NET | Microsoft 官方文档 将系统表映射到系统视图 (Transact-sql) - SQL Server | Microsoft 官方文档 一、注释中带某关键字的对象（sys.extended_properties） 主要用到 sys.tables 、sys.columns 、sys.procedures 系统对象表以及sys.extended_properties 扩展属性表 --查询列 SELECT A.name AS table_name , B.name AS column_name , C.value AS column_description FROM sys.tables A INNER JOIN sys.columns B ON B.object_id = A.object_id LEFT JOIN sys.extended_properties C ON C.major_id = B.object_id AND C.minor_id = B.column_id WHERE CAST(C.[value] AS VARCHAR(1000)) LIKE '%年假%'; --查询表 SELECT A.name AS table_name , C.value AS column_description FROM sys.tables A INNER JOIN sys.extended_properties C ON C.major_id = A.object_id AND C.minor_id = 0 WHERE CAST(C.[value] AS VARCHAR(1000)) LIKE '%请假%' --查询存储过程 SELECT A.name AS table_name , C.value AS column_description FROM sys.procedures A INNER JOIN sys.extended_properties C ON C.major_id = A.object_id AND C.minor_id = 0 WHERE CAST(C.[value] AS VARCHAR(1000)) LIKE '%年假%' 二、定义语句中带某关键字的对象（sys.all_sql_modules ） 主要用到 dbo.sysobjects 系统对象表以及sys.all_sql_modules 对象定义语句表 --老方式 SELECT DISTINCT b.name, b.xtype FROM dbo.syscomments a, dbo.sysobjects b WHERE a.id = b.id AND b.xtype = 'p' AND a.text LIKE '%LotMax%' ORDER BY name; --从 2008 开始，新方式 SELECT name, type_desc FROM sys.all_sql_modules s INNER JOIN sys.all_objects o ON s.object_id = o.object_id WHERE definition LIKE '%LotMax%' ORDER BY type_desc, name; 三、查找列名 select A.name as table_name, B.name as column_name from sys.tables A inner join sys.columns B on B.object_id = A.object_id where B.name like '%File%' order by A.name, B.name; 完整的列属性： with indexCTE as ( select ic.column_id, ic.index_column_id, ic.object_id from ZSOtherData.sys.indexes idx inner join ZSOtherData.sys.index_columns ic on idx.index_id = ic.index_id and idx.object_id = ic.object_id where idx.object_id = object_id('MouldTestResultDetail') and idx.is_primary_key = 1 ) select colm.column_id ColumnID, cast(case when indexCTE.column_id is null then 0 else 1 end as bit) IsPrimaryKey, colm.name column_name ,object_definition(colm.default_object_id) AS column_def, systype.name type_name, colm.is_identity is_identity,f.keyno as is_foreignkey, colm.is_nullable , cast(colm.max_length as int) ByteLength , ( case when systype.name = 'nvarchar' and colm.max_length > 0 then colm.max_length / 2 when systype.name = 'nchar' and colm.max_length > 0 then colm.max_length / 2 when systype.name = 'ntext' and colm.max_length > 0 then colm.max_length / 2 else colm.max_length end ) length , cast(colm.precision as int) precision, cast(colm.scale as int) scale,colm.is_computed, prop.value Remark from ZSOtherData.sys.columns colm inner join ZSOtherData.sys.types systype on colm.system_type_id = systype.system_type_id and colm.user_type_id = systype.user_type_id left join ZSOtherData.sys.extended_properties prop on colm.object_id = prop.major_id and colm.column_id = prop.minor_id left join indexCTE on colm.column_id = indexCTE.column_id and colm.object_id = indexCTE.object_id left join sysforeignkeys f on f.fkeyid=colm.object_id and f.fkey=colm.column_id where colm.object_id = object_id('MouldTestResultDetail') order by colm.column_id; 以上就是关于“SQL Server如何对特定对象搜索，SQL语句是什么”的介绍了，感谢各位的阅读。 （编辑：银川站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
