If the language collation of your production and staging site database server is different you can use the MySQL query below to create a new query that allows you to change the language collation of all database tables at once.
SELECT CONCAT("ALTER TABLE ", TABLE_SCHEMA, '.', TABLE_NAME," COLLATE latin1_general_ci;") AS ExecuteTheString
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA="DATABASE_NAME"
AND TABLE_TYPE="BASE TABLE";
