Tried it, but get the error invalid use of null.
The field I tried it on had no NULL values.
Will figure it out.
Bart,
I should have tested what I posted first. There is a small problem, the
julianday function needs a date string in YYYY-MM-DD format, but the
numeric calculations don't insert leading zeros for months and days less
than 10. Here i sa modified version that does leading zero insertion.
Even more reason to use the original substring based version.
select
cast (
julianday(
cast(20061204 / 10000 as integer) || '-' ||
substr('00' || (cast(20061204 / 100 as integer) % 100), -2,
2) || '-' ||
substr('00' || (20061204 % 100), -2, 2)
) - julianday('1900-01-01')
as integer
) as excel_date
;
