Answer / Anilkumarsingh
To pass values to and from a foreign function in Oracle D2K, you can use the PARAMETERS clause. This clause allows you to specify input parameters (IN) that are sent to the function, output parameters (OUT), and parameters that are both input and output (IN OUT). Here's an example:
```
DECLARE
myFunction (IN out_param1 number, IN out_param2 date);
BEGIN
myFunction(IN_PARAM1 => 5, IN_PARAM2 => SYSDATE);
END;
```
