Insert page returns error 'Duplicate entry '0' for key 'PRIMARY''

Yeah, using the tinyint data type for the ID would pose a problem...

the tinyint data type can only use 1 byte of storage.

A signed tinyint has a minimum value of -128 and a max value of 127.

the unsigned tinyint has a minimum value of 0 and a maximum of 255

the int data type on the other hand uses 4 bytes of storage.

A signed int has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647

The unsigned int has a minimum value of 0 and a maximum value of 4,294,967,295

more details on the different integer data types can be found here:
