I have a stored procedure in Oracle and I'm using an out 开发者_开发问答parameter in it.. I want to know how to display the output in Toad..
You just need to declare a variable to store the value in, and then do whatever you want with the data afterwards. If you are just wanting to see the output, dbms_output is probably the easiest way to go:
declare
-- declare variable to store out data in. Make sure datatype is correct
v_out VARCHAR2(50);
begin
-- call procedure, assigning value of out parameter to variable you declared
my_proc(
p_in => 3,
p_out => v_out
);
-- display value now in variable
dbms_output.put_line('Value of p_out: '||v_out);
end;
In the Toad schema browser, click the 'Execute' button, which will generate some test code for calling your procedure, and writing the OUT parameter via dbms_output. Check the output in the dbms_output window (you may need to activate output in the dbms_output window using the two leftmost icons)
In Toad after execution of a query you can see Multiple Options like Data Grid, Auto Trace, DBMS Output etc...
- Goto option DBMS Output.
- If Output is Turn Off (Red Dot), then click over it to Turn it On (Green).
- Now Execute your query with
CTRL+Enter
- This will show result after Poling Frequency Seconds.
Trial Code :
DECLARE
c number(4);
BEGIN
c := 4;
dbms_output.put_line(c);
END;
