Answer 1

here is a useful article

• auto increment with a string of numbers and letters

But basically I encourage you to create your own algorithm on this. You can add that algorithm in BEFORE INSERT trigger. Or you can do that on the front-end.

Example of pseudocode for the algorthm

• get the lastID [KP-0001]
• remove some characters and put it in a variable [KP-]
• convert the remaining into number since it's a string [0001]
• increment by 1 [1 + 1 = 2]
• convert it back to string and pad zero on the right [0002]
• concatenate the variable and the newly incremented number [KP-0002]
• save it.
