Some additional information. It appears it only occurs if you use uppercase tables names. CREATE TABLE SOMETABLE ( SOMECOLUMN BIGINT NOT NULL ) select * from information_schema.columns where table_schema = schema() AND TABLE_NAME = 'SOMETABLE' AND COLUMN_NAME = 'SOMECOLUMN' DROP TABLE SOMETABLE If you use sometable, then it will work, but SOMETABLE results in the error.

Thank you for the feedback. I also can repeat described behavior. Please try with current version 5.1.52 and if problem still exists indicate accurate version of MAC OSX you use and provide your configuration file.
