Question

I have two tables and want to compare rows on sqlite like this

table1           table2
field1           field1

a                   a
b                   d
c                   f
d                   g
e
f
g
h
i

and I want to produce result like this

result_table
field1

b
c
e
h

How is the syntax in sqlite?

Answer 1

SELECT DISTINCT Field1
FROM Table1 
WHERE Field1 Not IN 
    (SELECT DISTINCT Field1 FROM Table2)
