Does anyone know if Rdb/VMS has any limits to the number of table
joins that can be performed within a single query?
How about Oracle and Sybase: Do they impose any physical limits?
I have a proposal that requires up to 10 joins on a table. I need to
know how we stack up vs our competition.
Thanks in advance for any help...

Lisa, I don't know about Oracle or Sybase, but Rdb has a limit of 32 "contexts"... which would be roughly equivalent to a table (if you were to join the same table twice in the same query, it would count as 2). Sounds like Rdb is well within the 10 table requirement. | |||||
