IF I use the following statement:
SELECT * FROM `items` WHERE `item` = 10902 HAVING `venturi_type`
= 'universal' OR `venturi_type` = 'special';
I get a complete and full data dump.
IF I change the statement by inserting a 'letter' in this case 'S'
instead of a 'number' in this case '0' in the 'item', i.e. from 10902
to 109S2 I get the following error:
#1054 - Unknown column '109S2' in 'where clause
IF I change the statement by putting single quotes around '109S2' then
I get an SQL execution completed result from phpMAdmin, but NO data
dump!
The column 'venturi_type' is the same NO MATTER what part number 'item'
is and should display, yet it does not.
Why should it make a difference wether I have a letter or a numeral in
a part number?

Because the part number may be a string, not a number. Oh sure, it looks
like a number, but it is really a string. Also, the venturi_type should
be a conditional other than a HAVING....try this...
SELECT *
FROM `items`
WHERE `item` = '10902' <--(note single quotes around string)
AND (`venturi_type` = 'universal' OR `venturi_type` = 'special');
