从多列

Question

我想删除其值包含％DJ％和％SD％字符的行。而且我希望此查询从两个不同的列进行检查。表格名称＆＃39;位置＆＃39;，第一列名称＆＃39; start_location＆＃39;和第二列名称＆＃39; end_location＆＃39;。这是我想要执行的SQL查询：

DELETE FROM location WHERE start_location like '%DJ%' and start_location like '%SD%'

和

DELETE FROM location WHERE end_location like '%DJ%' and end_location like '%SD%'

所以我想在一个中执行此查询。

Answer 1

使用OR：

DELETE FROM location
WHERE start_location like '%DJ%' or start_location like '%SD%'
or end_location like '%DJ%' or end_location like '%SD%';

Answer 2

使用MySQL REGEXP运算符的简短解决方案：

DELETE FROM location 
WHERE start_location REGEXP 'DJ|SD' AND end_location REGEXP 'DJ|SD';

注意：如果要删除 列，请将AND替换为OR
