Question

i’m trying to save text in utf-8 languages (hebrew-arabic-etc..) and it fails .. first it was giving me (????????)
so i put this in dataSource.groovy
dbCreate = “update”
url = “jdbc:mysql://localhost/db_name?useUnicode=yes&characterEncoding=UTF-8”
}
and i’ve convert the whole database and it’s table to have collation utf-8 and charset also..

it gives me error says

ERROR util.JDBCExceptionReporter – Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation ‘=’

so what is the wrong am I doing..

Answer 1

The error states clearly that there’s a mixing of “latin1_swedish_ci” and “utf8_general_ci” collation. Please try checking again that you don’t have any field in any table that is still in latin1_swedish_ci COLLATE.
