When performing foreign key checks, InnoDB sets shared row-level locks on child or parent records it has to look at. How should I interpret "English is poor" review when I used a language check service before submission? The order of the columns in the index matters!

How to prevent Beamer from repeatedly expanding macros in \frametitle when frame-breaking My CEO wants permanent access to every employee's emails. This is called a referential integrity constraint between the two tables.

In MySQL 5.7.13 and earlier, InnoDB does not permit defining a foreign key constraint with a cascading referential action on the base column of an indexed generated virtual column.

Then each store must have a top general manager in charge which is stationed there, so the store will have an EmployeeID Foreign Key to the store table to represent that

Often, the 'unsigned' property on an ID column will catch you out. assist. Removing that resolved the problem. Therefore, it is required that the foreign key is equal to the candidate key in some row of the primary table, or else have no value (the NULL value).

It wasn't about the definition of the foreign key. If you have unsigned attribute on one primary key, you must have it on another. Temporary tables Temporary tables can't have foreign key constraints because temporary tables are not stored to the InnoDB data dictionary.
