RE: Re: Using variables

Could return a ref cursor - that would possibly approximate the sql server style of returning a table .....

Hmm a sqlserver programmer? In PL/SQL it looks like this:

declare
   theDate date;
begin
    theDate := TO_DATE('20120101','YYYYMMDD') ;
    select * from myTable WHERE TRANDATE = theDate order by TRANDATE, LOCAL_TIME;
end;

Worse part is, you code returns a temporary table, that is possible in Sqlserver. But that is NOT possible in Oracle. So the above code does not work too.
You must use cursors or varray's to return more data. So if you give more information on what you are trying to do, we could give hints to what you can do to solve the specific problem.

Yes, it was a TOAD question, and I think that was the problem. I was just creating the query, and apparently the default is "SQL Style" and that does not work (your query does work there, but not mine), but if I select "T-SQL Style" or even "Text' my query works, it seems I will need to RTFM as I do not know the differences. Thanks!

I'm a bit confused as to whether this is an SQL, PLSQL or TOAD question, but let's assume it's a TOAD question.  You can run a statement like yours in TOAD as follows:
select * from all_tables
where trunc(last_analyzed) = :thedate
order by last_analyzed;

The pop up that appears allows you to identify :thedate as a DATE and to enter a value.

In TOAD you could have many statements in the same editor window that use :thedate and they would use the same value, you wouldn't therefore need to create a PLSQL programme unit and specify a variable(s).

I am new to Toad and I am trying to do something very simple, but cannot figure it out, I want to set a value for a/some variable/s and then use them, for example:

begin
    :theDate := '20120101';
    select * from myTable WHERE TRANDATE = to_date(:theDate, 'YYYYMMDD') order by TRANDATE, LOCAL_TIME;
end;

But this has two problems to begin with, first it shows a window for me to set the value of the variable :theDate1, second it just fails for it expects an INTO clause (ORA-06550: line 3, column 5:
PLS-00428: an INTO clause is expected in this SELECT statement), so, how can I set up variables and then use them in subsequently sql statements (my version of TOAD is 11.0.0.116 if that matters.

TIA
