表太多,只记得这个表有一个mygame的字段,但是并不知道这张表在那个数据库下,只能根据这个字段查找对应的表和所在数据库
select table_schema,table_name from information_schema.columns where column_name = '字段名'
演例:
mysql> select table_schema,table_name from information_schema.columns where column_name = 'gname'; 查询结果: +--------------+-------------------+ | table_schema | table_name | +--------------+-------------------+ | ccc | mygame | # 可知道在ccc这个数据库下 | student | app01_class_grade | +--------------+-------------------+ 2 rows in set (0.36 sec)
