Espo.ERROR: (HY000) SQLSTATE[HY000]: General error: 1271 Illegal mix of collations for operation 'UNION'; GET /api/v1/GlobalSearch?q=rodrigo&maxSize=10&offset=0&orderBy =&order=; line: 149, file: /var/www/html/espocrm/application/Espo/Services/GlobalSearch.php

Global search returning error. What should I do?

All my tables using the same collation, as you can see below.



Thanks

Solved. the columns where not on the same collation.

Solved. the columns where not on the same collation.

Are you able to elaborate in case I run into this issue in the future. Not sure how you solve the issue at this stage.

I used a program to browse the database (HEIDISQL), and saw that, even the tables showing the same collation, the columns inside some tables were using a different one. So, using the HEIDISQL, I changed that columns collation as well
