1.查询表、视图、存储过程在哪些视图、存储过程、函数中被使用
SELECT DISTINCT OBJECT_NAME(id) name
FROM syscomments
WHERE id IN ( SELECT idFROM sysobjectsWHERE type IN ( 'V', 'P' ,'TF') ) --V表示视图，P表示存储过程，TF表示函数AND (text LIKE '%表名或者视图名或者存储过程名%')
2.查询包含SPDM字段的列以及对应的表
SELECT o.name as bname,C.name as lname
FROM syscolumns CINNER JOIN sysobjects o ON o.id = C.idAND o.type = 'U'
WHERE C.name LIKE '%SPDM%'
3.查询表名字包含KEHU的表
SELECT distinct o.name as name
FROM syscolumns CINNER JOIN sysobjects o ON o.id = C.idAND o.type = 'U'
WHERE o.name LIKE '%KEHU%'
)
