Hi Ananda, Ananda Kumar schrieb: So you set the collation_database=utf8_bin, what was your character_set_database values. character_set_database is utf8. The collation utf8_bin slows down queries, but is necessary in dealing with multilingual information. utf8_general_ci is faster, but can not distinguish in keys between symbols which are sorted at the same position in national character sets, like e.g. German a and ä, or French e and é.

LOAD DATA INTO doesn't work correctly with utf8
Hello, I would like to import data from a utf8-coded comma seperated file. I created my database with DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci and I started my mysql-client with the --default-character-set=utf8 option. Nevertheless, when I input primary key fields, which differ only in one umlaut character (e.g. achten and ächten) I get the following error message: ERROR 1062 (23000): Duplicate entry 'ächten' for key 1 (Same thing happens when I try to manually INSERT the row.) When I display my variable settings with SHOW variables LIKE 'c%'; I receive the following result: +--++ | Variable_name| Value | +--++ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results| utf8 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | | collation_connection | utf8_general_ci| | collation_database | utf8_general_ci| | collation_server | latin1_swedish_ci | | completion_type | 0 | | concurrent_insert| 1 | | connect_timeout | 5 | +--++ 14 rows in set (0.02 sec) From this I conclude it is the server setting, which causes the trouble here. When I manipulate the settings manually from the client (with SET character_set_server=utf8; SET collation_server=utf8_general_ci;) the values do change, but not the behaviour. But this can be expected, since the server is already up and running with the wrong settings. Does anybody know how I restart my mysql-server with the correct character and collation settings, if this is the cause for my problem, or if there might be any other reason for it. My mysql version is 5.0.26-12, running on a Suse Linux 10.2.

When I choose latin1 here, indeed, I don't receive an error message, but my data becomes corrupted. When, however, I choose utf8 and utf8_general_ci as session character_set_database and session collation_database, I still get the same error message. :( Best regards, H. -- Wouldn't the sentence 'I want to put a hyphen between the words Fish and And and And and Chips in my Fish-And-Chips sign' have been clearer if quotation marks had been placed before Fish, and between Fish and and, and and and And, and And and and, and and and And, and And and and, and and and Chips, as well as after Chips? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Edward Kay schrieb: Try using the SET NAMES 'utf8' statement [1] to tell MySQL that your client is sending data in UTF-8. I believe that as your server is latin1, it will assume this is the character set used by the command line client. [1] http://dev.mysql.com/doc/refman/5.0/en/charset-connection.html Edward I tried, but the behaviour remains the same. I guess my first option should be to force the server to use utf8 as default. I would have no problems in doing so, because I hardly use any latin1 anymore. But how would I do so? The mysqld has some options for this, but I didn't manage yet to simply restart it with new options, because it is started somewhere in the init.d-procedure of my Linux system and even as root I cannot simply invoke it from the command line.

If your inserting multi byte data, then u need to set the above parameters. This was one of the solutions give by mysql, i am not able to get the url. I will search my notes and get back to you all. When I load my multibyte data using latin character set and collation, I get the data loaded correctly into the database without error msg, but when I want to display it with SELECT * from table I don't get it displayed correctly, even after I change the settings back to utf8 after the import.

My mysql version is 5.0.26-12, running on a Suse Linux 10.2.

Dušan Pavlica schrieb: Try to convert file to latin1, if it's possible, create database with latin1 charset, create table with required structure (you can set utf8 charset to string fields ) and then load data. I can not convert the file into latin1, because it is multilingual (i.e. European, Japanese, Korean etc.). What client do you use to check whether data are OK? I can recommend MySQL Query Browser where I don't have to care about setting charset and collation parameters. I checked the file in MySQL Query Browser too, but even there I get it wrong, when I imported it with a latin session. I get it displayed right, when I import it with utf8, but then I have the message with duplicate keys and get only half of the data.
