Combining SELECT with SELECT DISTINCT in DBBrowser SQLite

Question

I've got a query to select distinct results with two tables which returns email addresses that don't occur in table2, but I'm having trouble also selecting data from the Table 2.First in this query for all rows with distinct emails. Is it possible to combine select statements in SQLite/DBbrowser in this way? My current query with the syntax I've tried is below

TABLE1:

table1email	Firstlast
[email protected]	Jim Robinson
[email protected]	Clark Stevenson

TABLE2:

table2email	First	Last
[email protected]	Jim	Robinson
[email protected]	Susan	Peters
[email protected]	Clark	Stevenson

QUERY:

SELECT table1email
FROM TABLE1
EXCEPT
SELECT DISTINCT table2email
SELECT First
FROM table2

Answer 1

The question doesn't seems to be very clear. Whatever I can understand from the question this seems to be the solution you are looking for.

SELECT table1email FROM table1 
WHERE table1email NOT IN (
    SELECT table2email FROM table2
);

This will work even if table2 have duplicate entries. But this will result duplicate entries from table1. If that is also needs to be eliminated, DISTINCT keyword can be used.

SELECT DISTINCT table1email FROM table1 
WHERE table1email NOT IN (
    SELECT table2email FROM table2
);
