Just to let you know that I have this all sorted now and that the problem
was the fact that
sqlite3.dll (the Windows dll) is compiled with the cdecl convention, which
is a problem with
callbacks back to a VB6 ActiveX dll as that expects std_call convention.
Once I compiled sqlite3.dll with
Is there something wrong or is there something missing from this sequence
of SQLite actions?
Note that all the return values are checked and are fine:
sqlite3_open_v2
sqlite3_create_function
sqlite3_prepare16_v2
run in loop till SQLITE_DONE:
sqlite3_step(lStatementHandle)
sqlite3_step will run
Yes, I didn't think there was a bug in SQLite here, but just wanted some
confirmation. Thanks for that.
I suppose the only way to get to the bottom of this is to run sqlite3.dll,
compiled with SQLITE_DEBUG
and SQLITE_MEMDEBUG enabled and look at the log/trace.

Been trying to get to the bottom of this, but no success.
Note that with one UDF in the statement all runs perfectly fine.
Could somebody confirm that they can run 2 UDF's (I have mainly tried with
the 2 the same UDF's) in the same SQL and that all
runs as how it should? Just to make sure there is

I am not familiar with C code or C debugging, but will look into that.

Could somebody tell me what happens after the callback function (to do with
sqlite3_create_function) has run, so after it has finished processing one row?

Still getting a crash here if I use the UDF more than once in the same
statement:
So, table with 2 integer columns and then doing:
select XXX(field1), XXX(field2) from table1
causes a crash.
I can see that the statement prepares fine and that the UDF gets called
twice (for the first row), but
dresses?

Not sure that is that simple as the code to produce the result is in an

Using the latest SQLite, 3.9.1, running on Windows 7.
Created a simple SQLite UDF with sqlite3_create_function and that function
only sets the result as a fixed integer value, 123.
The function is registered fine, so no error.
I call this function XXX.
Have a table like this:
CREATE TABLE
18 matches
