- I'm currently in the market for a Unix SQL database, and one of the products
- I'm considering is Ingres. I have a couple of questions about it. (Please
- E-mail or post any replies to comp.databases. I don't currently read
- comp.databases.ingres.)
-
- First of all, I understand that Ingres has a limit of ~2000 bytes per record.
- I know they have a way to incorporate large text fields in the database, but
- what about the situation where one just has a large number of different fields,
- none of which is large by itself, but the total sum is greater than 2000? The
- salesman claimed this wasn't a problem, but he couldn't explain why. Has
- anybody run into this problem, or know of a way to get around it? Is it a real
- problem with Ingres?
-
- What about importing and exporting text files? This is something that's going
- to be important for us. Are there any limitations involved with Ingres and
- importing/exporting text files? Are there problems doing this in a VMS
- environment?
-
- Another question I have is about row level locking. Somebody I was talking to
- claimed that Ingres does not have row level locking. However, since his only
- real experience is with the old public-domain version, I'm somewhat dubious
- about this claim. Is this true, or just a rumor?
-
- Thank you,
-
