Nothing new in that area that I know of. Oh, and iachar can be fine for checking for letters. There are many ways to do that. I agree with dpb that it depends on what you are actually doing... along with personal style preferences. I've done things like that with iachar, and I've done them other ways as well. I don't think there is a single universal "best" way. I don't respond to Robin directly (or even read his posts most of the time). I'm writing this only as a cautionary note. I recommend caution about trusting to get even simple matters of objective fact correct.

Precisely that last point was what I was trying to indicate was my opinion as well. Didn't intend to imply there was anything wrong w/ iachar() for some purposes; only what the other alternatives that have their own strengths/weaknesses are as that seemed the question. (And thanks for confirming there haven't been particular additions in the area...didn't think so but wasn't positive enough to so say.) --

I'm sure that some RDBMS vendors provide that capabilty. I don't believe ours (Ingres) does. ASCII unload, yes, but I don't believe its tab-delimited. Check with your vendor. Jim

You can compare the actual letters as character constants.

I know how to use the iachar() intrinsic in a simple and portable way to test if an unknown letter is a character, but not an arbitrary (possibly unknown) native processor collating sequence. $.02 -Ron Shepard |
