Question

I need to select data from two tables. However there are two columns, where if one or both rows read NO, I want to skip it.

Table 1

a--b--c-
1  r  l
2  t  f
3  d  c

Table 2

d--e--f--g-
1  r NO NO
2  r YES NO
3  r YES YES

QUERY:

 SELECT
    talbe1.a,
    table1.b,
    table1.c,
    table2.d,
    table2.e,
    table2.f,
    table2.g,
    FROM table1 INNER JOIN 
    table2 on table1.b = table2.e
    WHERE 'no' NOT IN (SELECT table2.f, table2.g FROM table2)

Answer 1

SELECT
    talbe1.a,
    table1.b,
    table1.c,
    table2.d,
    table2.e,
    table2.f,
    table2.g,
    FROM table1 INNER JOIN 
    table2 on table1.b = table2.e
        //if any of the f or g are not eqaul to "NO" only then select the result
        WHERE (table2.f != 'NO' AND table2.g != 'NO')

does not return if 
f = no and g = no
f = no and g = yes
f = yes and g = no

does return if
f = yes and g = yes
