SQL - How do I make an auto computing column?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I've created a table named House, which has the column 'area'.
I have another table named HouseFire, with the columns '%_Burnt' and 'area_burnt'.
I have values for both 'area' and '%_Burnt'. I want to make 'area_burnt' to automatically give me the value as soon as I input the % value in '%_burnt'.
I'm using heidisql

    You probably need a VIEW: w3schools.com/sql/sql_view.asp

    Tag your question with the database you are using.

  • I doubt that it's even possible to create an auto computed column based on a field from another table.

  • This seems to be a UI problem, not a database problem. Adjust the tags accordingly.
