Faster algorithm for max(ctz(x), ctz(y))? Now you can make a list of all columns you need to update with: Edit: Original syntax above had an error. Run the following SQL statements to get the result statements for updating character set and collation: I would write a script (in Perl, or whatever) to use information_schema (TABLES and COLUMNS) to walk through all the tables, and do MODIFY COLUMN on every CHAR/VARCHAR/TEXT field. The logical character sequence itself is unchanged. I would collect all the MODIFYs into a single ALTER for each table; this will be more efficient. You must have DBA/SUPER USER privilege to do: Setting the database parameters: innodb_large_prefix : ON; innodb_file_format : Barracuda; innodb_file_format_max : Barracuda; This should be the preferred answer using the latest collation and simply generates a migration script for you. From my work, I saw that ALTER the database and the tables is not enough. Section 10.1.11 of the MySQL 5.5 Reference Manual has some more information on this. By default, Utf8JsonWriter escapes all non-ASCII and HTML characters. Since MySQL 5.5.3 you should use utf8mb4 rather than utf8.

One statement like this: ALTER TABLE tbl_name CONVERT TO CHARACTER SET charset_name; Be sure to do this in a test enviornment first. You do not need to say use utf8 to use these and in fact you should not say that unless you really want to have UTF-8 source code.

The error though about "767 exceeded" isn't fixed in mariadb 5.5.x but is ok when tested in higher version (mariadb 10.2.x and higher). Use HeidiSQL. Its free and a very good db tool. This converts complete database from latin to utf8 in just a few seconds. HeidiSQL connects by default as utf8 so any special characters should now be seen as the character ( ) and not as encoded when inspecting the table data. You probably wont run into many issues going from latin1 => utf8 but in general you might run into collation "weirdness" when converting charsets. A database is a structured collection of data. How does a government that uses undead labor avoid perverse incentives? Can I trust my bikes frame after I was hit by a car if there's no visible cracking?

The no utf8 pragma tells Perl to switch back to treating the source text as literal bytes in the current lexical scope. I had to use "SET foreign_key_checks = 0;", then apply the changes, then "SET foreign_key_checks = 1;". Pythonic way for validating and categorizing user input. To specify a different escaping policy, create a JavaScriptEncoder and set JsonWriterOptions.Encoder. The Perl documentation is maintained by the Perl 5 Porters in the development of Perl. utf8::encode is like utf8::upgrade, but the UTF8 flag is cleared. That is, it replaces each sequence of characters in the string whose ords represent a valid (extended) UTF-8 byte sequence, with the corresponding single character. Since ASCII platforms natively use the Unicode code points, this function returns its input on them. I think (but am not sure) that Raihan's suggestion only changes the default for the table. This is especially true if you have any kind of unique constraints on char-ish columns. Check the columns on which you have indexes and if one of them is a varchar > 250 (most likely 255) then.

If you, like me, do not trust automation, this is how I have handled the problem. in perlunifaq. Tables containing only utf8 or utf8mb4 could be converted with "CCONVERT TO CHARACTER SET" as Mathias and MrJingles describes above, but then you risk MySQL changing the types for you, so you may be better of running "CHANGE COLUMN" instead since that gives you control of exactly what happens. utf8 - Perl pragma to enable/disable UTF-8 (or UTF-EBCDIC) in source code.
