Hi, I have used the following code to sort two sets of data:
awk '{printf "%10s %s\n",$1,$2}'
The first column is text and the second involves numbers. I was just wondering how i would go about sorting the second number so that they ascend from the top?
Thanks for any help (4 Replies)

drop_operator_class
DROP OPERATOR CLASS(7) PostgreSQL 9.2.7 Documentation DROP OPERATOR CLASS(7)NAME
DROP_OPERATOR_CLASS - remove an operator class
SYNOPSIS
DROP OPERATOR CLASS [ IF EXISTS ] name USING index_method [ CASCADE | RESTRICT ]
DESCRIPTION
DROP OPERATOR CLASS drops an existing operator class. To execute this command you must be the owner of the operator class.
DROP OPERATOR CLASS does not drop any of the operators or functions referenced by the class. If there are any indexes depending on the
operator class, you will need to specify CASCADE for the drop to complete.
PARAMETERS
IF EXISTS
Do not throw an error if the operator class does not exist. A notice is issued in this case.
name
The name (optionally schema-qualified) of an existing operator class.
index_method
The name of the index access method the operator class is for.
CASCADE
Automatically drop objects that depend on the operator class.
RESTRICT
Refuse to drop the operator class if any objects depend on it. This is the default.
NOTES
DROP OPERATOR CLASS will not drop the operator family containing the class, even if there is nothing else left in the family (in
particular, in the case where the family was implicitly created by CREATE OPERATOR CLASS). An empty operator family is harmless, but for
the sake of tidiness you might wish to remove the family with DROP OPERATOR FAMILY; or perhaps better, use DROP OPERATOR FAMILY in the
first place.
EXAMPLES
Remove the B-tree operator class widget_ops:
DROP OPERATOR CLASS widget_ops USING btree;
This command will not succeed if there are any existing indexes that use the operator class. Add CASCADE to drop such indexes along with
the operator class.
COMPATIBILITY
There is no DROP OPERATOR CLASS statement in the SQL standard.
