As of mid 2000 as many as 64 tables per query block can be joined. With self-joins each correlation name counts separately. However, there are factors that can reduce this number. I can list two of them here:

1. MaxParseTreeSegs value.

2. The number of implicit joins done by the optimizer, such as the join of a hash or single-table join index to the base table. I don't know whether you have such indexes.
