Ted is, and always has been, a King amongst VFP men and women. 😊

In the wondrous world of computer programming, not only do words have meaning 
but so do individual letters. And let's not get started on case sensitivity... 
I've been bitten by something like this before as I'm sure most of us have. The 
efficient brain takes shortcuts whenever possible so if you expected to see a 
particular thing in a particular context, it shows that to you.

Subject: RE: SQLite Problem - DSN-less Connection Doesn't Create A File

Ok, I formally nominate Ted Roche to be VFP King and SQLite Guru! All those
in favor? :)

I changed "DBNAME" in the connection string to "Database" and it worked
perfectly the first time. 

I knew it was going to be something stupid, but I didn't realize it was THAT
stupid. I can only claim programming blindness. I looked at the string in
Whil's book a thousand times and compared it to my code and never saw it.
I've been doing a lot of work lately connecting Foxpro to MySQL for another
project and DBNAME came over from that connection string. Of all the changes
I made to the connection string, I never changed, deleted or replaced the
Driver & DBAME key words. I changed everything else from the other key pairs
to the location and name of the database, but I am embarrassed to say I
never looked to the left of the equal sign to see the bad key word. Around
here they say, "If it had been a snake, it would have bit me."

One weird thing remains: As I mentioned in the original post, prior to
rebooting my computer, I NEVER got an error message and I always got a valid
handle back when I tried to make a connection and I was able to create
tables, insert data and select results. I can only assume it was because
SQLite allows you to create an in-memory database with a blank name, maybe
that was how I got a valid handle, but why did it fail to repeat that
behavior after the reboot? Was it because I established a valid DSN earlier
in testing and somehow it was piggy-backing on that connection? As I say,
weird. 

Thank you Ed for providing the ProFox list. Without this place I don't know
how long it would have taken me to figure this issue out if ever.

Having worked with Whil on a half-dozen books now, I have to say, weird
behavior is par for the course. ;)

Here's what I did. I called up a DSN I had previously created and like you,
copied the ConnectString when it opened. The only big difference I notice is
that my string is using "Database" rather than DBNAME.

? SQLStringConnect("Driver={SQLite3 ODBC
Driver};Database=C:\Users\tedro\Documents\newexample.sqlite;StepAPI=0;SyncPr
agma=;NoTXN=0;Timeout=;ShortNames=0;")
? SQLExec(4, "Create table Example2 (key int, description text)") ?
SQLExec(4, "insert into Example2 (key, description) values (1,'The first')")
? SQLExec(4, "insert into Example2 (key, description) values (2,'The
second')")


the "newexample.sqlite" database did not exist before I started. It's on
disk now, at 8 kb.
