mysql regex - 后跟特定字符串时过滤大于 XX 的数字

Question

Im searching for a RegEx that I can use in my MySql Query

What I want to archive is a query that filters all rows where there is a string with the the value "xx% to Fire Resistance" while xx is a dynamic value , lets say 22 , but I dont just want all rows with 22 but all rows with 22 AND higher . Is that somehow possible ?

I could filter it in a second step with php, but the initial result would be way to big to be practical to work with.

What I currently have (and does not rly work because it just filters for a number before the given string)

SELECT * FROM items WHERE `mods` REGEXP '\b(\d+(?:\.\d+)?)% to Fire Resistance\b'

What I would need in theory

SELECT * FROM items WHERE `mods` REGEXP '\b(\d+(?:\.\d+)?)% to Fire Resistance\b' > 22

one example "mods" field content

Some more text;+170 to Accuracy Rating;+25% to Fire Resistance;+4 to Armour;+6 to Evasion Rating;+43 to maximum Life;+39% to Lightning Resistance;Some more text;Some more text;

Answer 1

In MySQL versions before 8, you may use

REGEXP '[[:<:]](2[2-9]|[3-9][0-9]|[1-9][0-9]{2,})([.][0-9]+)?% to Fire Resistance[[:>:]]'

Details

• [[:<:]] - left-hand word boundary
• (2[2-9]|[3-9][0-9]|[1-9][0-9]{2,}) - a group matching
  • 2[2-9] - 2 followed with a digit from 2 to 9
  • | - or
  • [3-9][0-9] - a digit from 3 to 9 and then any 1 digit
  • | - or
  • [1-9][0-9]{2,} - a digit from 1 to 9 and then two or more digits
• ([.][0-9]+)? - an optional . and 1+ digits
• % to Fire Resistance - a substring
• [[:>:]] - right-hand word boundary
