通常需要查询某个字段来自于哪张表,在navicat中没有直接查哪些表有指定字段名的功能,只能用sql来查. 1.(按字段名查表)查询哪些表有指定字段名(比如查字段名article_id)的SQL: SELECT * FROM information_schema.COLUMNS WHERE COLUMN_NAME='article_id'; 或者 SELECT table_name, column_name FROM information_schema.columns WHERE column
意:本篇文章仅适用于mysql和postgre这两种数据库 1.查询数据库中所有表名及对应表的详细信息 select * from INFORMATION_SCHEMA.tables 2.根据指定名称查询表名(也可模糊查询,可查询表的详细信息) select * from INFORMATION_SCHEMA.tables where table_name = 'eguid'; select * from INFORMATION_SCHEMA.tables where table_name l
