How to import csv file to sqlite with correct data types

Question

When I import a csv file to sqlite database, it imports number as string to integer column, how can I fix this? A line from my csv file like this:

 31,c,BB R         


        

Answer 1

CSV files do no have data types; everything is a string.

To convert all values in a column into a number, use something like this:

UPDATE MyTable SET MyColumn = CAST(MyColumn AS INTEGER)
