General Error 1267 Illegal Mix Of Collations
MySQL. Illegal mix of collations (latin1_general_cs,IMPLICIT) and (latin1_general_ci,IMPLICIT) for operation '=' Any idea on what might be going wrong here? The collation of the table is latin1_general_ci and that of the column in the where clause is latin1_general_cs. mysql collation share|improve this question edited Aug 4 '14 at 19:07 user212218 asked Jun 12 '10 at 16:23 user355562 6983914 add a comment| 10 Answers 10 active oldest votes up vote 100 down vote This is generally caused by comparing two mysql error 1267 illegal mix of collations 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 6,19522240 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 Binary seemed to be the best solution for me. It might be the best for you as well if you aren't using any tricky filters. –Adam F Oct 1 '12 at 16:02 COLLATE worked for me. thanks –fedmich Oct 10 '15

After that check also the collation type of each table field that you have use in operation.

dreaded illegal-mix-of-collations error. The occasional query would result in Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation https://airbladesoftware.com/notes/fixing-mysql-illegal-mix-of-collations/ '='. MySQL’s default character set is latin1 with an adventurous Swedish collation, which presumably seemed like a good idea at the time. However Rails uses UTF-8 everywhere and from time to time the two collations collide. Fortunately this problem is not new and clever people have already solved it: see Getting out of MySQL Character illegal mix Set Hell and Fixing a MySQL Character Encoding Mismatch. Those two articles advise more or less the same process. Here I’m just jotting down some notes where I found something confusing or ambiguous in case I ever have to do this again. Order of events After exporting the data and hacking the dump file, I illegal mix of wasn’t sure whether to configure MySQL for UTF-8 and then import the data, or the other way round. I chose to import the data and then configure MySQL to avoid double-encoding the data. It seems to have worked. It silently truncated all my accented text but I was able to fix that. Take stock First figure out where you stand. In MySQL do this: mysql> show variables like 'char%'; The result you want is this: +--------------------------+----------------------------+ | 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/ | +--------------------------+----------------------------+ At this stage several of these values will be latin1. Similarly for collation: mysql> show variables like 'collation%'; +----------------------+-----------------+ | Variable_name | Value | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database | utf8_general_ci | | collation_server | utf8_general_ci
