Search Form won't return records

C

carriey

Hello There, I got this code off of some website many moons ago and have used
it dozens of times in building Search Forms. For some reason, this time I
can't seem to get it to return any results. At one point I did have trouble
before with the SQL statement but have gone through all my notes and believe
that this is the same as working copies of code that I have - I even played
around with the &'s and _'s but that didn't seem to do the trick.

I have double and triple checked this but must be missing a really silly
mistake. If anyone out there with a fresh pair of eyes can spot my error I
will forever indebted to you!!!!

The following lines are all missing leading space characters:

& "FROM Tbl_Department_Name" _
& "RIGHT JOIN C_Tbl_Employees" _
& "ON Tbl_Department_Name.Tbl_Department_NameID =

strOrder = "ORDER BY C_Tbl_Employees.[Employee_ID];"

They should read:

strOrder = " ORDER BY C_Tbl_Employees.[Employee_ID];"

Thank you Stuart for such a quick response. I added in those leading space
characters (feeling very sheepish indeed) and still I am not getting any
results returned. I did save and close and go back in, just in case that was
a problem but no luck. Any other ideas?

I hope this is correct - this is what I get in the immediate window after I
try to run a search (thanks again):

SELECT C_Tbl_Employees.Employee_ID, C_Tbl_Employees.ADPEmployeeID,
Tbl_Department_Name.DepartmentName, C_Tbl_Employees.LastName,
C_Tbl_Employees.FirstName FROM Tbl_Department_Name RIGHT JOIN C_Tbl_Employees
ON Tbl_Department_Name.Tbl_Department_NameID =
C_Tbl_Employees.Lookup_Department
WHERE (C_Tbl_Employees.[LastName]) Like '*White*
ORDER BY C_Tbl_Employees.[Employee_ID];

The only mistake I can spot is a missing apostrophe from the end of this
line:

WHERE (C_Tbl_Employees.[LastName]) Like '*White*

So now my true non-coding colors are showing through! Where on earth would I
look for that missing apostrophe in the code?

Thanks again!!!!

My eyes are burning!!!!! After going through the code over and over
comparing it to another database, I found that I needed 2 spaces before the
AND:
"*' AND"

I only had one space. Just thought I'd post in case anyone else comes
across this. Sometimes I find this coding so tedious!

So I take it the code is now working, ie producing the results you expect?
That's great. Next time it won't be so hard, considering the experience you
got debugging this.

Sorry to have to tell you that your fix mentioned above is a red herring.
One or two spaces makes no difference in SQL. You must have (deliberately or
inadvertently) changed something else.

We all (at any level of experience) suffer from 'code eyes' at one time or
another. You can stare at code till your eyes hurt and still miss something
really obvious. One of the features of the 'human condition', I'm afraid.

One thing I've found that helps is to use the 'cardboard programmer'
technique to flush these bugs out. Here's what you do: collar a colleague,
database-literate or not (not preferably), and ask them to help you out by
sitting with you while you describe what each portion of code is doing (or
supposed to be doing :). As you describe it, more often than not, you'll
spot a bug. Fix it, test it. If it's still not right, carry on describing...

The reason it's called the cardboard programmer is that you could do just as
well describing code to a cardboard-cutout of your colleague. The idea is to
force yourself to look at the code in detail, which you may have thought you
were doing before, but in reality weren't.

Eventually you won't need an actual person and you'll be able to do it in
your head.

Hope that helps

I think your real problem lies here. That code, which shaves off the last 5
characters from your sql string, is taking the last apostrophe with it. The
line ought to read:

strWhere = Mid(strWhere, 1, Len(strWhere) - 4)
