Mysql query LIKE search and using strings with symbols

由 喜夏-厌秋 提交于 2019-12-08 09:03:24
问题 My problem is having symbols used in the search query. I want users to be able to use symbols without being a problem, but the LIKE function in mysql seems to not be the solution so I need some help. EXAMPLE: If someone searches for "Blue's car" and "Blues car" is in the database, this query will return with 0 results. OR viseversa, if someone searches for "Blues car" and "Blue's car" is in the database, this query will return with 0 results as well. This is an example of what I'm currently

mysql query with like %..% in the where clause returning different results

由 ￣綄美尐妖づ 提交于 2019-12-08 08:31:31
I have the following problem (using mysql 5.0.70). In one table I have a varchar field containing some kind of a number, like: "0303A342", "21534463", "35663CE3" etc. Collation is set to utf8_general_ci . The problem shows up when a user of the system is trying to search for a record containing part of this number. SQL query looks like ... WHERE 'number' LIKE '%0303A%' Now if the 'A' in the LIKE part is entered as a Latin A, the result contains only records with Latin A's in them -- as it should. And when the A is Cyrillic , the results are again only those rows containing the Cyrillic A.

MySQL LIKE limiting

由 允我心安 提交于 2019-12-08 05:01:14
问题 Basicly I have a row in my table, that has the following format for it's value - 1,2,3,4,10,11,21,34 etc.. I'm retrieving values with LIKE statement, but since I'm using it with %<value>% , when searching for 1 it returns 11, 21, 1 and so on. How can I limit it, to return values based on one? 回答1: Instead of col LIKE '%<value>%' do col LIKE '%,<value>,%' OR col LIKE '<value>,%' OR col LIKE '%,<value>' OR col LIKE '<value>' or better yet col REGEXP '(.+,|^)<val>(,.+|$)' But the best solution
