Description:
In the connector python tutorial (https://dev.mysql.com/doc/connector-python/en/connector-python-example-ddl.html), one of the tables has the wrong structure.
Currently, it is:
TABLES['dept_manager'] = (
" CREATE TABLE `dept_manager` ("
" `dept_no` char(4) NOT NULL,"
" `emp_no` int(11) NOT NULL,"
" `from_date` date NOT NULL,"
" `to_date` date NOT NULL,"
" PRIMARY KEY (`emp_no`,`dept_no`),"
" KEY `emp_no` (`emp_no`),"
" KEY `dept_no` (`dept_no`),"
" CONSTRAINT `dept_manager_ibfk_1` FOREIGN KEY (`emp_no`) "
" REFERENCES `employees` (`emp_no`) ON DELETE CASCADE,"
" CONSTRAINT `dept_manager_ibfk_2` FOREIGN KEY (`dept_no`) "
" REFERENCES `departments` (`dept_no`) ON DELETE CASCADE"
") ENGINE=InnoDB")
The correct structure should be:
TABLES['dept_manager'] = (
" CREATE TABLE `dept_manager` ("
" `emp_no` int(11) NOT NULL,"
" `dept_no` char(4) NOT NULL,"
" `from_date` date NOT NULL,"
" `to_date` date NOT NULL,"
" PRIMARY KEY (`emp_no`,`dept_no`),"
" KEY `emp_no` (`emp_no`),"
" KEY `dept_no` (`dept_no`),"
" CONSTRAINT `dept_manager_ibfk_1` FOREIGN KEY (`emp_no`) "
" REFERENCES `employees` (`emp_no`) ON DELETE CASCADE,"
" CONSTRAINT `dept_manager_ibfk_2` FOREIGN KEY (`dept_no`) "
" REFERENCES `departments` (`dept_no`) ON DELETE CASCADE"
") ENGINE=InnoDB")
The problem is that the tutorial suggests loading the table dept_manager from the test_db project, where the data structure is different.
The result is that someone following these instructions will get a failure, and blame it on test_db rather than the incorrect tutorial
(https://github.com/datacharmer/test_db/issues/22)
How to repeat:
Follow the instructions in the page https://dev.mysql.com/doc/connector-python/en/connector-python-example-ddl.html
Suggested fix:
Swap the order of the first two fields in the dept_manager table
