AW: TIMESTAMPDIFF Not Found

Hi,

Date format YYYYMMDD is not allowed with DB2 UDF for i.

A character string representing a date in the format YYYY-MM-DD or
MM/DD/YYYY or DD.MM.YYYY can be converted into a real date without
specifying any date format:
Date(MyDate)

If you want to convert a numeric field (8,0 format YYYMMDD) into a real date
using the following syntax is the easiest:
Date(Digits(MyDate) concat '000000')

BTW it seems to me your time is 6,0 format HHMMSS.

To convert a numeric date (8,0) and numeric time (6,0) the easiest way is:
Timestamp(Digits(MyDate) concat Digits(MyTime))

Timestampdiff needs the difference between 2 timestamps defined as CHAR(22).
Not sure what SQL_TSI_SECOND is, in either way it needs to be an integer
with either value 1, 2, 4, 8, 16, 32, 64, 128 or 256.

Timestampdiff(2, Cast(MyTimestamp1 - MyTimestamp2 as Char(22)))

Hope this helps.

Mit freundlichen Grüßen / Best regards

Birgitta Hauser

Betreff: TIMESTAMPDIFF Not Found

I'm trying to debug a colleagues SQL statement, and when I put it into
Visual Explain, I'm getting an error that TIMESTAMPDIFF can't be
found. I'm also getting errors that the date format identifier
(yyyymmdd) is not in any of the tables. Is there a format identifier
on the date function? I'm playing around with the statement, removing
and adding to see if I can get it to work. Here's the original SQL
statement:

SELECT date( POSEVTP.EVDATE, yyyymmdd ) AS EVDATE,
XMSTNO,
XMINNO,
XMINVT,
POSEVTP.EVUSER,
POSEVTP.EVBEFR,
POSEVTP.EVAFTR,
POSEVTP_1.EVAFTR AS EVAFTR_1,
POSEVTP_1.EVUSER AS EVUSER_1,
TIMESTAMP( date( POSEVTP.EVDATE, yyyymmdd ), substr( digits(
POSEVTP.EVTIME ), 1, 2 ) || ':' || substr( digits( POSEVTP.EVTIME ),
3, 2 ) || ':' || substr( digits( POSEVTP.EVTIME ), 5, 2 ) ) AS
COLUMN0003,
TIMESTAMP( date( POSEVTP_1.EVDATE, yyyymmdd ), substr( digits(
POSEVTP_1.EVTIME ), 1, 2 ) || ':' || substr( digits( POSEVTP_1.EVTIME
), 3, 2 ) || ':' || substr( digits( POSEVTP_1.EVTIME ), 5, 2 ) ) AS
COLUMN0002,
FLOAT( TIMESTAMPDIFF( SQL_TSI_SECOND, ( TIMESTAMP( date(
POSEVTP_1.EVDATE, yyyymmdd ), substr( digits( POSEVTP_1.EVTIME ), 1, 2
) || ':' || substr( digits( POSEVTP_1.EVTIME ), 3, 2 ) || ':' ||
substr( digits( POSEVTP_1.EVTIME ), 5, 2 ) ) ), ( TIMESTAMP( date(
POSEVTP.EVDATE, yyyymmdd ), substr( digits( POSEVTP.EVTIME ), 1, 2 )
|| ':' || substr( digits( POSEVTP.EVTIME ), 3, 2 ) || ':' || substr(
digits( POSEVTP.EVTIME ), 5, 2 ) ) ) ) ) / FLOAT( 60 ) AS COLUMN0005,
XMRETL
FROM
NEWSYS.POSEVTP POSEVTP, NEWSYS.POSMSTP POSMSTP, NEWSYS.POSEVTP POSEVTP_1
WHERE
POSEVTP.EVTRAN=POSMSTP.XMTRAN AND
POSEVTP.EVTRAN=POSEVTP_1.EVTRAN AND
POSEVTP.EVAFTR=POSEVTP_1.EVBEFR AND
( POSEVTP_1.EVAFTR = 'I' AND POSEVTP.EVDATE = 20041219 )

Any help appreciated. Thanks!
