How to get the number of rows of the selected result from sqlite3?

Question

I want to get the number of selected rows as well as the selected data. At the present I have to use two sql statements:

one is

select * from XXX w         


        

Answer 1

To get the number of unique titles, you need to pass the DISTINCT clause to the COUNT function as the following statement:

SELECT
 COUNT(DISTINCT column_name)
FROM
 'table_name';
