Dpb,

within PL/SQL you can:

declare a variable to store the result from the function

func_res number;

within the PL/SQL block, call the function and store the result:

func_res := calc_radius(5);

or, you can select calc_radius(5) into func_res from dual;

You do NOT need to use the execute immediate command.

Hope this helps

Hi All

I have stored a user defined function as Varchar field in a table. How do I execute this function.

Here is the table where the function is stored.

SQL> select * from func;

FUNCTION_NAME

Calc_radius(5)

This procedure contains the following Code :

create function calc_radius(r in number) return number is begin
return 3.14*r*r;
end;

Executing this funtion at SQL Prompt give the output as

SQL> SELECT CALC_RADIUS(5) FROM DUAL; CALC_RADIUS(5)

78.5

I want to execute this function from a PL/SQL Block. I tried to store this function into a variable and then execute it. But it returns only the content of the field FUNCTION_NAME and not the value.

Can anyone suggest a solution for this problem ?

Regards
Dpb
