stored procedures - Laravel 5.4: Illegal mix of collations -

-



i have next error when i'm calling stored procedure:

sqlstate[hy000]: general error: 1267 illegal mix of collations (utf8mb4_general_ci,implicit) , (utf8mb4_unicode_ci,implicit) operation '=' (sql: call sp_getusuarios())

i'm using mariadb, , in database configuration have:

'mysql' => [         'driver' => 'mysql',         'host' => env('db_host', '127.0.0.1'),         'port' => env('db_port', '3306'),         'database' => env('db_database', 'forge'),         'username' => env('db_username', 'forge'),         'password' => env('db_password', ''),         'unix_socket' => env('db_socket', ''),         'charset' => 'utf8mb4',         'collation' => 'utf8mb4_unicode_ci',         'prefix' => '',         'strict' => true,         'engine' => null,     ],

i have eleven others stored procedures work fine. not work..

check collation type of each table, , make sure have same collation.

after check collation type of each table field have use in operation.

i had encountered same error, , tricks works on me.

you either need add collate where clause,

or add in parameter definition,

or alter field itself:

alter table tablea character set utf8 collate utf8_general_ci;

as default collation stored procedure parameters utf8_general_ci , can't mix collations.

unless need sort data in unicode order, suggest altering tables use utf8_general_ci collation.
