use a calculated column on the table which should put togather the Primary Key and the city, and whenever someone changes the city this code will change along

PKR = Static
KHR = City Column
AL = Static
01234 = Primary Key

syntax to create calculated column

ALTER TABLE [YourTable] ADD AutoCityCode AS ('PKR' + City + 'AL' + ID);
