Sorry, I had completely forgotten about the negative value working with
spaces in SSUB.

Subject: [RBASE-L] - Re: Converting Text to Date
Thanks Alastair. The delimiter is not a space but there is a space
between the date and the rest of the text - that's why I used the "-1"
in the SSUB (a negative number separates items based on a blank rather
than the current delimiter). Unfortunately, not all the date are
exactly 10 characters in length: 12/20/2008 is, 1/1/2009 isn't, so the
SSUB gave me that flexibility. Some dates don't have the year, e.g.
"9/7" so I originally skipped those with WHERE
(SLEN(SSUB(StockArriveDateT,-1))) >= 8. Hmm......

Using Razzak's method I can test the text var's length and if less than
6 (e.g. 12/20), assume the year needs to be added. I know, there are
other pitfalls (if they did enter a year, but only used 2 digits). But
this is for a potential client so I'm not going to get to extravagant
right now. It'll be fun to bring some order to their spreadsheet world.

Doug,
SSUB won't work in your example unless your DELIMIT character is a
space - unlikely!
Assuming that the position of the date in the string is constant you
could use SGET:
UPDATE MyTableTemp SET +
StockArriveDateD = (SGET(StockArriveDateT, 10, 1)))
which will give you the ten characters starting from position 1.
The update should work then assuming that the data matches your date
formats properly.
Regards,
Alastair.

Subject: [RBASE-L] - Converting Text to Date
Happy Snowy Friday from WI, list.
I would like to extract part of a text column and insert into a date
column.
The data looks like: 4/9/2008 confirmed
So I've tried:
UPDATE MyTableTemp SET +
StockArriveDateD = (SSUB(StockArriveDateT,-1)))
(StockArriveDateD is a date col, StockArriveDateT is a text 30 col)
That gets the first word of the text column, 4/9/2008.
But, the "Expression does not return a valid date"
I tried adding DEXTRACT, but apparently DEXTRACT can't be fooled into
converting text, it wants a DATETIME datatype.
So, how do I convert a date-looking text into a valid date? I looked
through the functions and tried several, but to no avail.
