如何在mysql中查询所有表是否包含某个字段

在select语句的where子句中使用like关键字,例如 select * from 表1 where 列1 like '%计算机%' 表示查找列1中包含“计算机”字样的结果。 其中%代表任意多个字符,下划线代表一个字符。

information_schema.columns这表保存了所有字段信息 SELECT count(*)FROM information_schema. COLUMNSWHERE TABLE_SCHEMA = 'world' AND TABLE_NAME = 'city' AND COLUMN_NAME = 'ID'查询条件可以自己去修改

select table_schema,table_name,column_name from information_schema.columns order by table_schema,table_name

用like语句查询。 SQL Server语法如下(如查询包含spt的表) select name from sys.objects where type='U' and name like '%spt%';结果: Oracle语法如下(如查询包含test的表) select table_name from user_tables where table_name like '%T...

mysql> SELECT COLUMN_NAME, DATA_TYPE, IS_NULLABLE, COLUMN_DEFAULT -> FROM -> INFORMATION_SCHEMA.COLUMNS -> WHERE -> table_name = 'test_main' -> AND table_schema = 'test' -> //+-------------+-----------+-------------+-----------...

SELECT * from 表名 where `字段名` REGEXP '[a-z]+' 查询出的就是这个字段里包含字母的数据了

有两种方法: 1.select b.name 表名,a.name 字段名 from syscolumns a join sysobjects b on a.id=b.id where b.xtype = 'U' 2.select [name] from sysobjects where id in(select id from syscolumns Where name='字段名')

应该是不需要存储过程的。下面通过查找字段名为姓名为例。1.select OBJECT_NAME(id) from syscolumns where id in(select id from sysobjects where type='U')and name='姓名'2.第二个问题更简单了select OBJECT_NAME(id) from syscolumns where...

select table_schema,table_name from information_schema.columns where column_name = 'htmlpath'用这条语句就能查询出来,其中 table_schema 是所在库, table_name 是所在表

select d.name as table_name, a.name as column_name from syscolumns a inner join sysobjects d on a.id = d.id and d.xtype = 'U' where a.name = 'stu_id'
