The 'var' variable can be used as a bind variable in pl/sql.
Variables referenced with & or && are substution variables.
The code in your example looks incomplete to me, or the programmer
just didn't bother to complete it, as Mladen has already suggested.
Here's a ( rather useless) example of using both substitution
and bind variables in sqlplus.
var cmd_line_arg varchar2(10)
begin
select '&&1' into :cmd_line_arg from dual;
end;
/
print cmd_line_arg

To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> cc: Subject: var source_data varchar2(12) |
My original posting had a few lines truncated, so here I go again:
I'm looking at a PL/SQL script that goes like this
-- Header
var Source_Data VARCHAR2(12)
DECLARE
Num1 NUMBER;
BEGIN
Source_Data := '&1';
What's the purpose of having a VAR statement in front or Before
of the Declare section? Is it used for bind-variables, is that what it is?
thx
maa
