Can any one give an example of the difference between a column_alias and a column_definition when using a function in the FROM clause?
from the manual: http://www.postgresql.org/docs/8.2/interactive/sql-select.html "function_name ( [ argument [, ...] ] ) [ AS ] alias [ ( column_alias [, ...] | column_definition [, ...] ) ]" Regards, Richard Broersma Jr. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
