SQL基础：搜索 SQL Server中搜索特定的对象

–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%’

–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;

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;
