Indirect Referencing

Question

Dear All Assalam-o-Alikum,
i have write this code
DECLARE
V VARCHAR2(50):='V1';
V1 NUMBER;
BEGIN
dbms_output.put_line(v);
end;
now i want that what ever value variable "V" contain, this vale consider as variable and value should be assign to this variable like this
IF V contain value "V1" then we can able to assign the value to v1 through programming. i want to do this on PL/SQL. i have done this on Form but i want to do this on Database Level.
I want to know how can i do this.
Thanks
Best Regadrs

Answer 1

So, do you mean like this?
V1 -> V -> 'Oralce'
V1 should hold the value of the variable 'V' even though 'V' was referred as a Value to V1 rather a variable?
Like
V1 Varchar2(30) := 'V';
In that case, AFAIK..
1. Oracle PL/SQL does not follow forward reference
2. A value is a value and a Variable is a variable, Values inside single quote cannot be considered as Variable.
But you can do this
PRAZY@solarc> declare
  2  V number := 30;
  3  V1 varchar2(10) := V;
  4  V2 Varchar2(10) := 'V';
  5  begin
  6  DBMS_OUTPUT.PUT_LINE('Value of V1 :'||V1);
  7  DBMS_OUTPUT.PUT_LINE('Value of V2 :'||V2);
  8  end;
  9  /
Value of V1 :30
Value of V2 :V
PL/SQL procedure successfully completed.Text marked with in single quotes will be considered as value at all cost.
