The supplied parameters to Zend_Auth_Adapter_DbTable failed to produce a valid sql statement

Question

I have the following exception Caught exception: The supplied parameters to Zend_Auth_Adapter_DbTable failed to produce a valid sql statement, please check table and colum

Answer 1

As Kervin has already answered, this error appears because of collation mismatch between php and mysql.

You can either stop using utf8 as suggested in the above solution or you can change the database table to use utf8.(It worked for me only after I deleted the data inside the table and reinserted them.)
