Logical AND operator in mySql REGEXP?

Question

I use MySql REGEXP:

SELECT * FROM myTable
WHERE title REGEXP \"dog|cat|mouse\";

The dataset is small, so I am not concerned about performan

Answer 1

You can add several conditions with AND between them:

SELECT * FROM myTable
WHERE title REGEXP "dog" AND title REGEXP "cat" AND title REGEXP "mouse";

Maybe REGEXP is not necessary here and you may use INSTR instead (regular are usually slower):

SELECT * FROM myTable
WHERE INSTR(title, "dog") AND INSTR(title, "cat") AND INSTR(title, "mouse");
