SQL Server中搜索特定的对象

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_descriptionFROM    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_idAND 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_idAND 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_idAND 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.xtypeFROM     dbo.syscomments a, dbo.sysobjects bWHERE    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_descFROM     sys.all_sql_modules s INNER JOIN sys.all_objects o ON s.object_id = o.object_idWHERE    definition LIKE "%LotMax%"ORDER BY type_desc, name;

三、查找列名

select   A.name as table_name, B.name as column_namefrom     sys.tables A inner join sys.columns B on B.object_id = A.object_idwhere    B.name like "%File%" order by A.name, B.name;

完整的列属性：

with indexCTEas ( 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 / 2when systype.name = "nchar" and colm.max_length > 0 then colm.max_length / 2when 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 Remarkfrom     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_idwhere    colm.object_id = object_id("MouldTestResultDetail")order by colm.column_id;
