Re: SQL Select Question
Try This
select
a.field_1,
a.field_2,
...
from table_a a
where not exists
(select 'x'
from table_b b
where b.field_1 = a.field_1)
Usually works for me.

Subject: SQL Select Question
I realize that this is really an SQL question, and not an SQR question
but I was hoping that with everyone's expertise here I could get a
quick (and satisfactory) answer.
Here's my question. I want to create a report that selects about 10
columns from a single table. The selection should be based upon field
values within that table. Also (and here's where I'm having
problems), I need to look at another table to see if the first table's
primary key is represented in it. If it is, I want to exclude it from
my selection. Do you follow that? Here's a crude visual:
TABLE A TABLE B
100 98
101 100
105 108
107 110
110
111
In the above example I would want to select 101, 105, 107 and 111 from
Table A. Can anyone give me a hand? Thanks in advance,
Dunc.
