Select from dual return 3 rows !

Select from dual return 3 rows !

Think what Rudy was trying to say is that it is a table and that
additional rows CAN be inserted....not that they SHOULD.....or WOULD....



Mistakes happen.....





I have hit this issue twice in 13 years....once I THINK it was because
of an import...the other ....I have no stinkin' clue.....



But on both, applications started going crazy due to the multiple rows
returned when only one expected.....fix was drop the table, recreate it
and recreate the public synonym......this with Oracle support on the
line......

  DUAL, when you really come down to it, is really just a table
into which Oracle defaults with just a single record. However, because
it is just a simple table, additional records can be inserted into it,
as you have just discovered.

 


That is version dependent.

At least as far back as 8.1.7.4, there can
be only one row in sys.dual.

Try it.
