This article mainly introduces whether the mysql database supports like or not, which can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Mysql supports like,like to vaguely match any multi-character match or any single character, which will be used in combination with "%" and "_"; for example, "% a" matches data ending in a, "% a%" matches data containing a, "_ a_" matches data with three digits and the middle letter is a, and so on.

Fuzzy query using Like in MySQL

The so-called "fuzzy query" corresponds to "precise query". For example, if we want to query whether a field value is equal to 1, we can write "where column=1" in the SQL statement, which is the exact query. Precise queries are easy to understand, but we often use fuzzy queries. For example, I want to look up a user from the user table, but I can't remember to clean up his name. I only know that there is a word "Hong" in his name. then the fuzzy query comes in handy.

Like matching / fuzzy matching, will be used in combination with% and _.

'% a' / / data ending with a' a%'/ / data starting with a'% a%'/ / containing three digits of a with the middle letter of'_ a'/ / two digits of an and ending with two digits of'a'/ / with the beginning of a

Query for information that begins with the java field.

SELECT * FROM position WHERE name LIKE 'java%'

Query information that contains the java field.

SELECT * FROM position WHERE name LIKE'% java%'

Query the information that ends with the java field.

SELECT * FROM position WHERE name LIKE'% java'; Thank you for reading this article carefully. I hope it will be helpful for everyone to share whether the mysql database supports like content.
