select table_name from information_schema.tables where table_schema='tablename' and table_type='base table' and table_name like '%_copy';
information_schema 是mysql系統自帶的資料庫,提供了對資料庫元資料的訪問
information_schema.tables 指資料庫中的表(information_schema.columns 指列)
table_schema 指資料庫的名稱
table_type 指是表的型別(base table 指基本表,不包含系統表)
table_name 指具體的表名
如果本身是在tablename 這個庫里新建的查詢,可以去掉 table_schema='tablename ' 這一句
select table_name from information_schema.tables where table_type='base table' and table_name like '%_copy';
select * from systables where tabname like 'saa%'
此法只對informix資料庫有用
select column_name from information_schema.columns where table_schema='csdb' and table_name='***'
select count(1) from information_schema.tables where table_schema = 'test' and table_name = 'd_ad';
select count(*) tables, table_schema from information_schema.tables where table_schema = 'test' group by table_schema;
