Here is what the code does. I set up the UDF after I open a file,
like this:
� sqlite3_create_function( pDb, "format_time", -1,
SQLITE_UTF16, 0, format_time, 0, 0 );
The format_time function formats the time according to a template and
calls sqlite3_result_text16, like this:
sqlite3_result_text16( context, pMem, nLen,
UdfCleanupCallback );
The memory is allocated to pMem and the text data copied into it.
Then the function returns. That's all.
One thing I noticed is that the nLen must be the number of bytes
allocated in pMem - not the number of wide chars in pMem. This is
unexpected, since we're calling the wide char (*16) version of
sqlite3_result_text.
Thanks for the help.
Quoting John Stanton :
The problem appears to be in your function. Post the code for it.

I'm trying to get the concat operator to work with my
user-defined
function. This works fine:
SELECT UPPER(FirstName) || ' ' || UPPER(LastName) FROM
Employees
But this doesn't work:
SELECT FORMAT_DATE(login_time) || ' ' ||
FORMAT_TIME(login_time)
FROM Sessions
I get only the formatted date - missing the formatted time.
FORMAT_DATE is my own user-defined function that returns text data
type.
Can someone *please* check into this. I must get this
working.
Thank you
