Thank you johnsone.
Can you comment on why you used column - new value verses the define statement? I am somewhat new to SQLPlus and until this issue the define statement always worked for me.
Thanks.

Question
Assign variable in SQL Plus tool
I am trying to declare a variable in SQL plus using the SQL Plus tool, not create a package but using the user interface tool. Then set the variable using a value from a SQL statement. Then finally use that value as a filter to several other queries. Here is what I have so far but I am having trouble assigning the SYSDATE less one hour to my variable "StartTime". The value comes through as the character string SQL not the SYSDATE less an hour.
undefine StartTime;
define StartTime = SELECT SYSDATE - 60/1440 FROM DUAL;
SELECT '&StartTime' FROM DUAL;
SELECT * FROM TABLE1 WHERE CREATE_DATE > '&StartTime';
SELECT * FROM TABLE2 WHERE UPDATE_DATE > '&StartTime';
SELECT * FROM TABLE3 WHERE RECEIVED_DATE > '&StartTime';

That is always the way I have done it since Oracle 7. The define is not necessary.
By no means is this the only way to do what you want. My preferred way would be declaring a variable and using it in a bind, but it sounded like you wanted to avoid that.
variable StartTime varchar2(100);
begin
select to_char(sysdate - 60/1440, 'mmddyyyyhh24miss')
into :StartTime
from dual;
end;
/
select :StartTime from dual;
SELECT * FROM TABLE1 WHERE CREATE_DATE > to_date(:StartTime, 'mmddyyyyhh24mis');
SELECT * FROM TABLE2 WHERE UPDATE_DATE > to_date(:StartTime, 'mmddyyyyhh24mis');
SELECT * FROM TABLE3 WHERE RECEIVED_DATE > to_date(:StartTime, 'mmddyyyyhh24mis');

This should do what you are looking for:
column StartTime new_value StartTime;
select sysdate - 60/1440 StartTime from dual;
SELECT '&StartTime' FROM DUAL;
SELECT * FROM TABLE1 WHERE CREATE_DATE > '&StartTime';
SELECT * FROM TABLE2 WHERE UPDATE_DATE > '&StartTime';
SELECT * FROM TABLE3 WHERE RECEIVED_DATE > '&StartTime';
