Breaking this down
The first returns more than the second because it's an OUTER JOIN -
therefore all records in EbethCustRpt3 that don't have entries in
tblUsers will be included, while the INNER JOIN will only return records
that are in both
As for three and four, that's because you're using EXISTS wrongly, it
returns TRUE or FALSE, not a query...
If
SELECT tblUsers.nameFirst,
EbethCustRpt3.nameLast
FROM tblUsers
Returns any results, then EXISTS returns true, you're using NOT EXISTS,
so you might as well put
SELECT nameFirst, nameLast
FROM EbethCustRpt3
WHERE FALSE
Not to mention that the third query, the SELECT is referring to a table
that isn't in the FROM - if you're only using one table, don't put the
table name in front of the field names
What you might want to try is;
SELECT nameFirst, nameLast
FROM EbethCustRpt3
WHERE nameFirst + ' ' + nameLast in
(SELECT nameFirst + ' ' + nameLast
FROM tblUsers)
Although that might return some entries which are slightly wrong, so
changing the ' ' to something like '-+-+-' or similar to stop similar
names coming through
