Elementary: what is the dollar-sign ($) in a column name mean?
raindogNov 24 2010 — edited Nov 24 2010I periodically see dollar signs in column names in Oracle tables. For example, when I create a LOB, often times the LOB segment will end in a dollar-sign (or two). Sometimes when one of the developers creates an object, I see some of the field namess have dollar-signs at the end of them.
What does the dollar-sign mean?
What does two dollar-signs mean?
Just curious...they seem to function as normal characters.
