Hi:
I'm running a simple query on an Access Table from VB6.0. The operator can
make several different selections. Based on their selection, a different,
specific SQL needs to be run. So, when the operator says... "Do it"...the
click procedure goes to a Function (based on their selection)...th e specific
function builds the correct SQL and returns it...then it sends that query to
the final procedure to run the sql, retrieve the data and put it on my form.
When I run the program, it returns the data in the first three fields, but
the fourth field is empty...there is data in that field in the table...but
it is not returned. I've checked the SQL that is being passed and it is
being passed correctly.
When I put a "MsgBox SQL" to check out the SQL (after the SQL is developed
and before it is actually run in the final procedure) the SQL is correct and
all of the data is printed on the form (that is when the program pauses and
waits for the operator to click on the message box). When there is no pause
for a message box, the data is not returned...when them message box is
there, the data is returned correctly.
CAn anyone tell me what the heck is happening? And how I might get around
this without having the operator read and close a message box?
Any assistance or suggestion would be helpful.

I think we need to see some code.
It is doubtful your SQL is being affected by the msgbox, it has to be
something in how you are attempting to capture or view the value.
Because the returned values are variants, a msgbox can on occasion affect
displayed results by 'fixing' the value to a specific type. But that is
uncommon and just a wild suggestion on my part.
Review how you are capturing the values of that last field. Doing anything
cute?

Hi Ralph:
I have data in one table and each record shows the number of trips taken by
each type of vehicle each day, with dispatch times, arrival times, etc. I
want to compare vehicle type 1's "chunk" of data for a given period of time
with the same vehicle's "chunk" of data a year ago. (Compare Jan 1, 2005 to
Feb 1, 2005 with Jan 1, 2006 to Feb 1, 2006). So I "append" the frist set
of data from table one into table two...then update table two with the info
from an SQL getting the corresponding data for the second part of the
comparison. ONce in the second table, I use another SQL to bring the data
into a datagrid. But when I do that, the first time the process runs, the
second amount of data does not show up in the grid... I refresh it, but that
doesn't change anything. If put a "msgbox" in the procedures just before
the grid is loaded...all data shows...without the "msgbox"... the second half
of the data is dropped.
So...yes, I'm doing some funky things with the data as it is moved to set it
up as I need it for the comparison. Each SQL works right...I've checked
each one in Access..and they work... but when I put them together...the
second part of the data is dropped. (If I try to compare over a three year
period, the first and second year show up...but the third year is
dropped.)..
So... I'll just have to see if I can work around this some way.
Thanks
JP

This is clearly a timing problem, which the msgbox "fixes" by putting in a big
fat delay. It has something to do with the way you are using the grid, not with
SQL or the database. Refreshing does not always mean the same thing as Requery,
and sometimes just means the display is repainted. After you are done with all
data modifications, be certain that you are re-running the query that pulls the
data into the grid.
Thanks Steve:
As I was writing the last note for the board, I realized that all I had to
do was use a cross tab query and that might "fix" the problem...rathe r than
moving the data to a different table...then querrying it... I tried
it...and, by golly, it worked... KISS has always escaped me (Keep it simple
stupid...) :0)...thanks for taking the time to reply.

Noob alert.
Code is below.
File is saved as a .php.
What I'm trying to do:
User uses 'select' box drop down list to pick a value.
Value ($site) is derived from a db query. This works fine.
Value selected is used as the 'where' clause of the 2nd query.
If $site is a single word, the 2nd query works like a charm.
If $site is more than one word (has spaces), the query returns a null

I have several tables based on exactly the same fields

However, as I have many different tables (the tables are different
