Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8_unicode_ci,IMPLICIT) for operation '=' in MySQL Stored Procedure

Question

I checked the database table and found it was in latin1_swedish_ci so i\'ve changed it to utf8_general_ci then I changed the collation from latin

Answer 1

COLLATE utf8_unicode_ci

add to the query end, like this;

SELECT * FROM table COLLATE utf8_unicode_ci;

Answer 2

so the answer is simple. It seems you missed the change as stated by MKJ ^^ but the actual syntax to alter your tables looks like this.

alter table `dbname`.`tablename` convert to character set utf8 collate utf8_general_ci;

Applied as an individual script or at the end of your create table statement you should be able to relate all related tables back to the same charset
