1074, "Column length too big for column 'err_solution' (max = 21845); use BLOB or TEXT instead"

 　一个注意点，就是sqlalchemy 使用create_all()建表的时候，要在 create_all()所在页面import那些表的model

　　

sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (1074, "Column length too big for column 'err_solution' (max = 21845); use BLOB or TEXT instead") [SQL: u' CREATE TABLE amazon_errcode ( create_date DATETIME, modified_date DATETIME, id INTEGER NOT NULL AUTO_INCREMENT, err_code INTEGER, err_desc VARCHAR(1024), err_solution VARCHAR(65532), PRIMARY KEY (id) ) ']
