MySQL REGEXP usage within Boolean Match/Against

由 让人想犯罪 __ 提交于 2019-12-23 18:31:33
问题 I have the following MySQL query: SELECT title, description FROM some_table WHERE MATCH (title,description) AGAINST ('+denver (REGEXP "[[:<:]]colorado[s]*[[:>:]]")' IN BOOLEAN MODE); the "regexp" here looks for a "complete word" colorado (with or without the ending "s"). I want to actually select only those rows that have ("denver") AND ("colorado" or "colorados"). But I cannot put a "+" for the REGEXP. I tried but got 0 results, although there are rows in the table that match the requirement

MYSQL match against query two tables

由 空扰寡人 提交于 2019-12-13 03:37:13
问题 Is it possible to do a match against a query with two tables using a join? The tricky part might be the index on the table but maybe there is a way.. sql is not my strong suit. Many thanks. I imagine it might be something like the following: SELECT * FROM 'pages' p LEFT JOIN `tags` t ON p.id = u.pageid WHERE MATCH(p.shdescript,t.tag) AGAINST ('romance, relationship') Many thanks 回答1: It's possible, but you need to have text indexes. mysql> alter table pages add fulltext index_text(shdescript)

MySQL Match() Against() Case-Sensitive

由 心不动则不痛 提交于 2019-12-10 19:19:09
问题 Currently, my database is charset Latin1 meaning SELECT * FROM TABLE MATCH(column1) AGAINST('"words here"' IN BOOLEAN MODE) will only return in-sensitive searches. The problem though is that my database will be searched with in-sensitive and case-sensitive searches. Is there a way to solve this so that I can use the same table to do the searches? Is that even possible or will I be forced to make a table with latin1_bin charset to query if the user's search is case sensitive. 回答1: A naïve
