Is it possible to select columns and perform complex operations on them, for example, select factorial(column1) from table1orselect integral_of(something) from table2
select factorial(column1) from table1
select integral_of(something) from table2
Perhaps there are libraries that support such operations?
Yes, you can call all the predefined functions of your database on the selection columns, and you can use CREATE FUNCTIONto define your own.
