Mysql Illegal Mix Of Collations For Operation 'concat'

add a comment| 10 Answers 10 active oldest votes up vote 100 down vote This is generally caused by comparing two strings of incompatible collation or by attempting to select data of different collation into a combined column. The clause COLLATE allows you to specify the collation used in the query. For example, the following WHERE clause will always give the error you posted: WHERE 'A' COLLATE latin1_general_ci = 'A' COLLATE latin1_general_cs Your solution is to specify a shared collation for the two columns within the query. Here is an example uses of the COLLATE clause: SELECT * FROM table ORDER BY key COLLATE latin1_general_ci; Another option is to use the BINARY operator: BINARY str is shorthand for CAST(str AS BINARY). Your solution might look something like this: SELECT * FROM table WHERE BINARY a = BINARY b; Or, SELECT * FROM table ORDER BY BINARY a; share|improve this answer edited Jul 26 '14 at 22:54 answered Jun 12 '10 at 17:17 defines 6,20522240 2 Thanks. Actually it seems to be behaving pretty weird in my case. When I run the query as it is, via the query browser, it fetches me the results. But using a stored procedure throws up an error. –user355562 Jun 13 '10 at 6:21 4 Binar

And if I copy and paste the outputted query into a phpMyAdmin SQL window, it runs fine, producing the expected result. I had a previous problem where PHP could not use LOAD DATA INFILE. I wonder if this is a similar type of problem. But I can't see how it would be.

Apparently, I have been using PHP with MySQL without ever needing to worry about client collation. I don't know if this will lead to other problems, but for the moment I've solved this problem by adding the following query to the main controller (so that the query is run for every script on the site). SET NAMES "utf8" COLLATE "utf8_general_ci"; Now my query works through my PHP script. I suppose that phpMyAdmin might take the collation of whatever tables you are querying and set the client collation accordingly. I'm just guessing on that one. Here's where I found the answer: http://dev.mysql.com/doc/refman/4.1/en/charset-collation-charset.html share|improve this answer answered Jan 11 '13 at 6:31 Buttle Butku
