SQL Server中搜索特定的对象
作者:springsnow
这篇文章介绍了SQL Server搜索特定对象的方法,文中通过示例代码介绍的非常详细。对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下
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;
