I'm trying to have sqlite automatically do the calculation below for each column. I used the following line but not getting the intended result[see picture]

Any help is appreciated.

    shares, current_price, 
    shares * current_price as 'Total' 
FROM portfolio

enter image description here


The '$' in the current_price column indicates it is treating current_price as a string. From the Datatypes in SQLite Version 3 doc:

SQLite uses a more general dynamic type system. In SQLite, the datatype of a value is associated with the value itself, not with its container.

The heart of the problem is the portfolio insert.
