I am doing the chapter on temporary tables. Should I show examples using TEMP or TEMPORARY? -- Bruce Momjian | http://www.op.net/~candle pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

TEMPORARY is SQL92 standard, TEMP is not. Nuff said...

OK, but TEMPORARY doesn't work on 6.5.*, right? -- Bruce Momjian | http://www.op.net/~candle pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

I think in 7.0 we just allowed TEMP as a user column. For the book, TEMPORARY it is. -- Bruce Momjian | http://www.op.net/~candle pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

Sure it does (at least as far as I can tell. The test/locale stuff has
screwed up CVS update, so I have to do a clean checkout of at least
that directory to get my tree back in shape :(
And, to beat a dead horse, I'm *still* not sure why we are carrying
along the "TEMP" variant, losing the use of that name for other
things.

Well, Tom Lane made it so we allow TEMP as an indentifier. I now remember that the issue with 7.0 was that everyone beat up on me because I used TEMP instead of the SQL92-standard TEMPORARY when implementing temporary tables. See, it works now: test=> create table x ( temp char(2));CREATE -- Bruce Momjian | http://www.op.net/~candle pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

Won't 7.0 be the release version by the time the book is actually published? :) - Don Baccus, Portland OR <dhogaza@pacifier.com> Nature photos, on-line guides, Pacific Northwest Rare Bird Alert Serviceand other goodies at http://donb.photo.net.

I was just getting confirmation before putting in a 7.0-specific thing. However, TEMPORARY is supported in 6.5.*, so I am in good shape with TEMPORARY. -- Bruce Momjian | http://www.op.net/~candle pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026
