I want to store languages other than English in MySQL database using Ruby. I've tried to store Hindi language characters in MySQL database, but got ActiveRecord::StatementInvalid error. Here is the attached screenshot -
Please help me solve this problem. Thanks in advance.
You could run the following command on your desired table(s):
ALTER TABLE <table_name> CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
MySQL docs on collation and character set configuration.
Hope it helps!

I started my Project with UTF8 Database for the development. At the time of project completion, my Professor gave me the database of type Latin1. Because of Type Conflicting my project is not working properly, result my server side code doesn't access the database.
I tried much conversion: My Professors database into UTF8, but it failed.
Still I’m facing the issue. Kindly assist me in this regards.
Thank you !
You may try a charset converter like MySQL charset converter
This PHP script can be used to convert your MySQL database tables from latin1-to-UTF8 while retaining the integrity of all internal multibyte characters.
You could try this:
ALTER TABLE tbl_name CONVERT TO CHARACTER SET charset_name;
replace charset_name with latin1
You can also change columns individually
ALTER TABLE TableName MODIFY ColumnName ColumnType CHARACTER SET latin1;
Can anyone tell me how can i store for example russian words in database? Please write an example. I know that i must use unicode, but don't know how use with mySql.
Thanks all for response.
You should create a database with utf8 character set and russian collation.
Find the russian collation:
SHOW COLLATION LIKE '%russian%'
Then create the database:
CREATE DATABASE db_name CHARACTER SET utf8 COLLATE latin1_russian_ci;
You can also ALTER it if you already have one.
Read the manual here https://dev.mysql.com/doc/refman/5.7/en/charset-database.html
I am having an issue with a MySQL database. I have two copies of it: development and production. Today I realised that:
The production database has the encoding format utf8_general_ci
The development database has the encoding format latin1_swedish_ci.
My question:
Is it possible to change the encoding of my development database to look like the production one? How can I perform that in a easy way?
And, for the noobs like me, what are the main differences between the two formats. Which one would you recommend? Which one is the most standard on the industry?
Thanks in advance.
question 1: Yes, it's possible
ALTER DATABASE `test` CHARACTER SET utf8 COLLATE utf8_general_ci;
but You have to be carefull if nothing will change after switch. Only english, will change easyly... special characters could be a problem.
question 2: You have to read more: http://dev.mysql.com/doc/refman/5.5/en/charset-general.html because there are issues like sorting, charset range...
Here are the settings of the source database:
and here are the settings of the database on the new server
When I use the export function on the source database, I set "Character set of the file:" to utf-8. I verified the dump and all the non-english characters are there as they should be.
I used the following command before uploading the database on the new server:
ALTER DATABASE dbname CHARACTER SET utf8 COLLATE utf8_general_ci;
Then I upload the dump on the new server. I use SHOW FULL COLUMNS FROM table_name;
and under "collation" some columns have NULL and others have utf8_general_ci
But when I access the website all the non-english characters are jumbled like this: été
Can anyone please help me? I don't know much about mysql but I have looked around on google and stackoverflow and I couldn't fix it.
Thank you very much.
I'm trying migrate a MSSQL database to MySQL. Using MySQL Workbench I moved the schema and data over but having problems converting the character encoding. During the migration I had the tool put text into BLOBS when there was problems with the encoding.
I believe I've confirmed that the data that is now in MySQL is *latin1_swedish_ci*. To simplify the problem I'm looking at ® symbols in one of the columns.
I wanted to convert the BLOBS to VARCHAR or TEXT with UTF8 encoding. I'm running this SQL command on one of the columns:
ALTER TABLEbookdetailsMODIFYBookNameVARCHAR(50) CHARACTER SET utf8 COLLATE utf8_unicode_ci;
Instead of converting the ® it is just removing them which is not what I want. What am I doing wrong? Not that reading half the internet trying to find a solution isn't fun but 3 days in and I think my eyes are about to give out.
MySQL workbench has a UI that is relatively simple to nav. If you need to change the collation of the tables or schemas, you can right click them on the Object Browser and go to alter table, or alter schema there you can change the data types, and set the collation to whatever you want.
