I have a database that is uft8_general_ci, only problem is up until this point an application coded by a previous developer seems to have been working with the database in latin-1.
I have since changed how the app uses the database and can now store an umlaut as an umlaut instead of ü. The problem now is that the application reads the previously existing data from the database as (example) 'Süddeutsche' instead of 'Süddeutsche'.
Is there anyway to convert the data inside the database from one format to the other?
Regards
Edit:
ALTER TABLE TableName MODIFY ColumnName ColumnType CHARACTER SET latin1;
ALTER TABLE TableName MODIFY ColumnName ColumnType CHARACTER SET binary;
ALTER TABLE TableName MODIFY ColumnName ColumnType CHARACTER SET utf8;
This worked for me.
To change the character set encoding to UTF-8 for the database itself, type the following command at the mysql> prompt. Replace dbname with the database name: Copy ALTER DATABASE dbname CHARACTER SET utf8 COLLATE utf8_general_ci; To exit the mysql program, type \q at the mysql> prompt.
Similarly, here's the command to change character set of MySQL table from latin1 to UTF8. Replace table_name with your database table name. mysql> ALTER TABLE table_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci; Hopefully, the above tutorial will help you change database character set to utf8mb4 (UTF-8).
utf8mb3 supports only characters in the Basic Multilingual Plane (BMP). utf8mb4 additionally supports supplementary characters that lie outside the BMP. utf8mb3 uses a maximum of three bytes per character. utf8mb4 uses a maximum of four bytes per character.
what is the difference between utf8 and latin1? They are different encodings (with some characters mapped to common byte sequences, e.g. the ASCII characters and many accented letters). UTF-8 is one encoding of Unicode with all its codepoints; Latin1 encodes less than 256 characters. Does this answer your question?
You could try SET NAMES
to let the Database talk in latin-1
with your application while storing in utf-8
or you will need to convert all previous Datasets to utf-8
