Converting utf8mb3 to utf8mb4: A Guide
In this utf8mb3 vs utf8mb4 tutorial video I'll show you how to convert utf8mb3 to utf8mb4. Enjoy!
SQL queries used in the video:
1) Set a character set and collation across the entire SQL database:
ALTER DATABASE dbname CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
2) Set a character set and collation across a table:
ALTER TABLE tablename CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
3) Set a character set and collation for a specific column:
ALTER TABLE tablename CHANGE col_1 col_1 VARCHAR(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
Replace "dbname" and "tablename" with your SQL database and table names. Also if you're changing the collation of a column, make sure to alter the amount of characters that can be stored in the column if necessary.
