java - mysql的查询正则表达式怎么写？

Question

mysql现在有一个字段code,我现在需要的规则是，前一位(或两位)我提供了固定值，java后台生成的，比如I或IC。然后后四位随意，然后后两位后面的4位java后台也会生成，也是固定的，最后末尾还有三位随意。比如I17 04 0000 000或IC17 04 0000 000

难么mysql的select语句怎么写，求大神告知。。。。
PS.1位(两位)固定，四位随意，四位固定，三位随意
select code from xxxx where？？

Answer 1

SELECT code FROM xxxx WHERE code REGEXP '^(I|IC)[0-9]{4}0000[0-9]{3}$';

or

SELECT code FROM xxxx WHERE code LIKE 'I____0000%' OR code LIKE 'IC____0000___';

Answer 2

where code REGEXP is followed by a regular expression

Answer 3

In addition to using like, can other methods be used for fuzzy search in MySQL?

Answer 4

Use like, mysql does not have regular expressions, so there is no need to use regular expressions for your needs.
