Mysql Illegal Mix Of Collations For Operation '='

msg on MySql: Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation '=' I have gone through several other posts and was not able to solve this problem. The part affected is something similar to this: CREATE TABLE users ( userID INT UNSIGNED NOT NULL AUTO_INCREMENT, firstName VARCHAR(24) NOT NULL, lastName VARCHAR(24) NOT NULL, username VARCHAR(24) NOT NULL, password VARCHAR(40) NOT NULL, PRIMARY KEY (userid) ) ENGINE = INNODB CHARACTER SET utf8 illegal mix of collations (latin1_swedish_ci implicit) and (utf8_general_ci coercible) COLLATE utf8_unicode_ci; CREATE TABLE products ( productID INT UNSIGNED NOT NULL AUTO_INCREMENT, title VARCHAR(104) NOT NULL, picturePath VARCHAR(104) NULL, pictureThumb VARCHAR(104) NULL, creationDate DATE NOT NULL, closeDate DATE NULL, deleteDate DATE NULL, varPath VARCHAR(104) NULL, isPublic TINYINT(1) UNSIGNED NOT NULL DEFAULT '1', PRIMARY KEY (productID) ) ENGINE = INNODB CHARACTER SET utf8 COLLATE utf8_unicode_ci; CREATE TABLE productUsers ( productID INT UNSIGNED NOT NULL, userID INT UNSIGNED NOT NULL, permission VARCHAR(16) NOT NULL, PRIMARY KEY (productID,userID), FOREIGN KEY (productID) REFERENCES products (productID) ON DELETE RESTRICT ON UPDATE NO ACTION, FOREIGN KEY (userID) REFERENCES users (userID) ON DELETE RESTRICT ON UPDATE NO ACTION ) ENGINE = INNODB CHARACTER SET utf8 COLLATE utf8_unicode_ci; The Store Procedure I'm using is this: CREATE PROCEDURE updateProductUsers (IN rUsername VARCHAR(24),IN rProductID INT UNSIGNED,IN rPerm VARCHAR(16)) BEGIN UPDATE productUsers INNER JOIN users ON productUsers.userID = users.userID SET productUsers.permission = rPerm WHERE users.username = rUsername AND productUsers.productID = rProductID; END I was testing with php, but the same error is given with SQLyog. I have also tested recreating the entire DB but to no good. Any help will be much appreciated. mysql stored-procedures share|improve this question asked Aug 2 '12 at 2:05 Manatax 1,14311329 add a comment| 5 Answers 5 active oldest votes up vote 83 down vote accepted You either need to a

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 http://stackoverflow.com/questions/3029321/troubleshooting-illegal-mix-of-collations-error-in-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 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 6,18522240 2 Thanks.
