MySQL正则表达式在列上搜索

Question

I want to do a MySQL search on a column with this regex pattern:

/\\w.*\\s(Metro)\\s\\d{2}[-]\\d{4}/g

So my MySQL query is:

SELECT vehicle_plate_number 
from users 
where vehicle_plate_number REGEXP '\w.*\s(Metro)\s\d{2}[-]\d{4}'

I have like 7 thousand entries with matching pattern but MySQL is returning zero results. Can't seem to detect the mistake here.

MySQL's REGEXP has its own particular syntax. It doesn't support \\s , \\d , or \\w , but we can still approximate these. Here is a version of your pattern which seems to work:

SELECT vehicle_plate_number 
FROM users 
WHERE vehicle_plate_number REGEXP '[a-z0-9].*[[:space:]]Metro[[:space:]][0-9]{2}[-][0-9]{4}';
