I did read some about the file locking issues so I'll continue to look
into that.
Regarding testing with sqLite3, I'm not sure what to do with it. I
downloaded the pre-compiled binary for Windows 64. It gave me 2 files,
sqlite3.def and sqlite3.dll but I'm not sure what to do with them.
Shell commands from within Livecode don't work. Suggestions?

I suppose I should also mention the usual caveat about using sqlite over a
networked file system, which is that sqlite relies on file system locking
to preserve data integrity and some networked file systems are buggy in
that area according to the sqlite website.

Peter - thanks for jumping in here. Yes, I can read and write files to
this location and, as a matter of fact, I can even do a straight read of
the database file on the server and get the same cryptic characters back
I get when I read the local copy. I just can't establish a connection
to it for the purpose of issuing revDatabase calls.
You're right when you say the "unable to open the database file" is not
very informative. I get the same message when I try that on an empty
path on the server.
I'll try your sqLite3 suggestion and let you know how it works.
Thanks!

You might want to try opening the database with something other than
Livecode in hope that you will get a more informative error message.
sqlite3 is the official sqlite command line tool. It's distributed
with
OSX but not sure if it's included with Windows.
Are you able to access any other files in the same directory as the
sqlite
db?

Devin - thanks for the idea but that's not it. I just checked and
everything on my Windows 8.1 system matches case with the database file
path on the Linux server. I even tried changing the name of the
database file to all lower case but that didn't work either. Thanks...

Ray,
You may have moved your DB file from a system that is not case
sensitive, like MacOS, to one this is case sensitive, like Linux. Do
all of
your folders and file names have the same exact spelling, including
upper
and lower case letters, as the string in your path variable?

...one other note. I'm guessing calls to sqLite need drivers. These
drivers are probably built in to Livecode and the OnRev server which
would
explain why LC's database commands works so well locally and with the
OnRev
based samples.
If this is the problem, does anybody know how I could install these
drivers on my own server?

I've never worked with sqLite databases before but it appears I
should
be able to access one on a server pretty much the same as I do locally.
Here's what I've done:
put revOpenDatabase("sqLite",localPath) into theDbId
-- this creates a zero K local database file
put "CREATE TABLE bugs(Name char(50), Date char(50))" into
myQuery
revExecuteSQL theDbId,myQuery -- the local database file is no 2
K
revCloseDatabase theDbId -- close it or I won't be able to copy
it
to the server
I then copy the local database file to a remote server and make sure
all 9 permissions are checked (777).
I now load the well-tested server path into the variable dbPath and
try this:
put revOpenDatabase("sqLite",dbPath) into myResult
but all I get back is:
Error: Unable to open the database file
Suggestions?
