Hi all,

I know that this is a simple question, and that I should know the answer
... but I don't. *blush*

Given two tables, how do I write a select that will show me all the records
that are in Table1 but NOT in Table2?

CREATE TABLE TABLE1
(
RECORDNO INTEGER NOT NULL,
SEQUENCENUMBER INTEGER,
PRIMARY KEY(RECORDNO)
);

CREATE TABLE TABLE2
(
RECORDNO INTEGER NOT NULL,
SEQUENCENUMBER INTEGER,
PRIMARY KEY(RECORDNO)
);

In this example, assume that I want to find all of the records in Table1
where there is no matching record in Table2.

Thanks in advance,

Tim
