FIND_IN_SET() उपयोग
select * from yourTableName where find_in_set('searchValue', csvColumn) > 0;
उदाहरण
mysql> create table demo81 (id int not null auto_increment primary key, username varchar(200));
mysql> insert into demo81(username) values('John,Chris,David'), ('Mike,Sam'), ('Chris,Bob,Sam'), ('Mike,John,Chris');
"Chris" खोजना
mysql> select * from demo81 where find_in_set('Chris', username) > 0;
+----+------------------+ | id | username | +----+------------------+ | 1 | John,Chris,David | | 3 | Chris,Bob,Sam | | 4 | Mike,John,Chris | +----+------------------+
लाभ: सटीक टोकन मिलान; "Chris" → "Christina" से मेल नहीं।
