#1267 - Illegal Mix Of Collations (ascii_general_ci,IMPLICIT)
I installed MySQL 4.1.7 on my home computer with IIS along with PHP as a development environment. I also installed PHPMyAdmin 2.60 for a GUI approach to managing MySQL.

Problem/Issue: In each table structure, there is a field called "Collation" which defaults to "latin1_swedish_ci". I never dealt with collation before, nor do I know what it does. All I know is that I get and error with a very simple query:

#1267 - Illegal mix of collations (ascii_general_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='

Is there an easy way to do away with collation, so it works the same way that it does on most the servers that I use, where collation isn't even present. I suppose this is either something new with PMA 2.6.0 or MySQL 4.1.7.

Illegal Mix Of Collations Database Error 1267?
I'm getting this strange error while processing a large number of data...

Error Number: 1267

Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='

SELECT COUNT(*) as num from keywords WHERE campaignId='12' AND LCASE(keyword)='hello again æ˜" ã‹ã‚‰ ã‚ã‚‹ å æ‰€' What can I do to resolve this? Can I escape the string somehow so this error wouldn't occur, or do I need to change my table encoding somehow, and if so, what should I change it to?

Getting Error - Illegal Mix Of Collations?
I have the stored procedure:

Code: [Select]CREATE PROCEDURE `procedure_currency_update`(IN `pRate` FLOAT, IN `pCurrencyAbr` TINYTEXT)
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT 'Updates a currency in the 'currency' table with new rate info.'
BEGIN.............

I call it like:

CALL procedure_currency_update(1.4641, 'AUD');

The error that MySQL reports is:

Code: [Select]Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation '='

I checked the 'currency' table and it is utf8_unicode_ci.

Illegal Mix Of Collations :: For States Field
I have a table in my MySQL database that has a field called location. The default value for this field national. Other than that value the field will hold a the name(s) of a state such as california, arizona, new mexico, idaho. In trying to build my recordset I keep getting an error when I try something like this:

select * from affiliates where location = 'national' order by name

I have tried numerous variations with the apostrophes but no luck. What am I missing here?

Illegal Mix Of Collations In Stored Procedure?
Hi, my stored procedure in MySQL fails with Mysql::Error: Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8_unicode_ci,IMPLICIT) for operation '='.

The procedure fails when in SELECT clause it tries to compare a VARCHAR column with VARCHAR parameter passed to this procedure. All the columns in my tables have utf8_unicode_ci collation. Database collation is the same. I have even specified collation in `/config/database.yml.

However, when I run /script/console I have following variables set:

>> ActiveRecord::Base.connection.select_rows "show variables like '%colla%'"
=> [["collation_connection", "utf8_general_ci"], ["collation_database", "utf8_unicode_ci"], ["collation_server", "utf8_general_ci"]]

And possibly the most interesting fact is that I have another database on the same MySQL server with same collations (even querying for collation variables from Rails console gives same results) which runs this stored procedure without any problem.

Character Encoding - Illegal Mix Of Collations
I need to transfer a column from one table to another. The source table has a different collation than the target table (latin1_general_ci and latin1_swedish_ci). I use

UPDATE target
LEFT JOIN source ON target.artnr = source.artnr
SET target.barcode = source.barcode

I get an "illegal mix of collations". What is a quick fix to get this working without having to change either table? I tried CONVERT and COLLATE to run the whole operation in UTF-8, but that didn't help. "barcode" contains numeric data only (even though they all are VARCHARs), so there are no collation worries either way. I need to do this just once.

Edit: I sorted it using a CAST(fieldname as unsigned) on every field involved. I was able to do that in this case because only numeric data was affected, but it would be nice to know a more general approach to this, so I am leaving the question open.

Illegal Mix Of Collations(both Table Has Same COLLATE)?
I have a following stored procedure

Code:

DELIMITER $$
DROP PROCEDURE IF EXISTS `myproc_t1` $$
CREATE DEFINER=`shuchi`@`10.10.10.117` PROCEDURE `myproc_t1`()
BEGIN
DECLARE done INT DEFAULT 0;
declare temp1 varchar(20);
declare temp2 varchar(20);
declare p_id varchar(20);
declare parent_id varchar(20);
declare temp3 varchar(100);...........

When I try to execute the procedure using CALL myproc_t1(), I get following ERROR message

Illegal mix of collations (latin1_general_cs,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation '='

Also When I do show create table PRODUCT_CATEGORY_MEMBER and show create table PRODUCT_CATEGORY for both I get ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_general_cs'

I dont see anywhere latin1_swedish_ci for any table.

Illegal Mix Of Collations In Store Procedure
I get this error: Illegal mix of collations (greek_general_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation '=' when I call this store procedure of mine:

[CODE.....]

although I have no problem when I run an UPDATE query directly: UPDATE vehicles SET st='Καλημέρα' WHERE id='A001';. I have tried to explicitly declare the charset for each column, etc. The problem seems to occur only when I call the procedure.

Illegal Mix Of Collations Error In MySQL?
I am getting the following error in MySQL:Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=this is in response to a query in my application:

SELECT count(1) as idExists
FROM user
WHERE userName = 'خالد'

As far as I understand, this is happening because the characters being entered are foreign to the collation type used for my table. So my question is what collation should be used to handle this? The user table is currently set to UTF8 which I thought was the correct one, but obviously I'm wrong. Should it change to Latin1 or is there a better collation that handles all characters??

Php - Illegal Mix Of Collations (latin5_turkish_ci,IMPLICIT) And (latin1_swedish_ci,COERCIBLE) For Operation '='?
How can i solve

"Illegal mix of collations (latin5_turkish_ci,IMPLICIT) and (latin1_swedish_ci,COERCIBLE) for operation '='" problem?

My query: select * from up where name='camış'

connection options:

SET NAMES 'latin5'
SET character_set_connection = 'latin5'
SET collation_connection = latin5_turkish_ci

I changed the collate as latin5_turkish_ci but doesn't work. Between, after a few minutes (lots of queries), the problem disappears on its own.

Error - Uncaught Exception 'MySQLiQuery_Exception' With Message 'Illegal Mix Of Collations
I've got this error: Fatal error: Uncaught exception 'MySQLiQuery_Exception' with message 'Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=': select id from 'addresses' where 'shiptozip'='13000' and 'shiptostreet'='Františka Křížka'

As you can see, I'm trying to get an ID from the table addresses.

mysql> show variables like 'character%';

| 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 | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |...............

Where the table 'addresses' also has utf8_general_ci and utf8. I guess it's got something to do with the query Františka Křížka, as it's ok with other queries. The server_collation used to be latin_swedish_ci but I think I've managed to change that all now (as you can see from the above tables).

"Illegal Mix Of Collations" MySQL Error
What I am attempting to do with an SQL query is grab data from multiple tables for outputting to an Excel spreadsheet file using PHP. Each row should show details for each member, as queried from multiple tables (using the field 'PersonalID' as the primary/foreign key). The query I have is as follows:

SELECT tblcoreuser.PersonalID, tblcoreuser.usrForename AS Forename, tblcoreuser.usrSurname AS Surname, tblcoreuser.voucher AS Free_Status, tblcoreuser.Joined AS Date_Joined, tblcoreuser.Package AS Membership_Package, tbladdress.Address1, tbladdress.Address2, tbladdress.County, tbladdress.Postcode, tblcredits.numCredits AS Remaining_Credits

FROM tblcoreuser, tbladdress, tblcredits

WHERE tblcoreuser.PersonalID = tbladdress.PersonalID AND tblcoreuser.PersonalID = tblcredits.PersonalID

ORDER BY tblcoreuser.PersonalID DESC;
The error being returned is:

Illegal mix of collations (latin1_general_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation '='

I've tried removing certain parts of the query, but cannot seem to pinpoint the exact cause of the problem. I'm sure I'm missing something simple -

Error - "Illegal Mix Of Collations"
I was going through the error log of my Rails application and found that someone had run into the following error:

"Mysql::Error: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=': SELECT * FROM `tags` WHERE (name = LOWER('?')) LIMIT 1"

I understand the reasoning for this error, however I am running into trouble trying to fix it because I cannot duplicate it. My database connection uses a utf8 connection, and the tags table's collation is latin1_swedish_ci, but no matter what I try to do I cannot duplicate the error. Should I just change tags to use utf8_general_ci collation and hope this fixes the problem?
