RE: DATA TYPE QUESTIONS?
[snip]
Thanks for your reply but I think you are missing my point or I am
missing yours either way the query does not work when I substitute the
S for a 0 in the part number as I described previously in detail. You
focus on 10902 which does work whether I put single quotes around same
or not. The problem is when I use another legitimate part number that
has a letter in IT,i.e. 109S2, IT does not work whether I put single
quotes around IT or not! I have tried the 'AND' 'OR' qualifiers but it
makes no difference! Please reread my post carefully!!

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?
[/snip]
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 HAVINGtry this...
SELECT *
FROM `items`
WHERE `item` = '10902' --(note single quotes around string)
AND (`venturi_type` = 'universal' OR `venturi_type` = 'special');
[/snip]
I did read and then re-read carefully your postand the single
quotes are required when the 'S' is there because MySQL thinks that you
have specified a column namenot data. That is why you get a
successful completion of the query when the quotes are there. Since you
cannot specify a column name as a number, when you use the number minus
the 'S' you are essentially asking if the `item` is TRUE (which it is),
so therefore you get all of the data back. Make sense?
Do you have an item 10902 with a universal or special venturi? Do you
have an item 109S2 with a universal or special venturi?
You can also try
SELECT *
FROM `items`
WHERE `item` = '10902'
AND `venturi_type` IN('universal','special');
