i think what dan means is its not useful to use IMMEDIATE in your sample because its already know thaat table you going to select is “employee”. know not because you put it into variable but because you using
v_name employees.last_name%TYPE;
v_sal employees.salary%TYPE;

i think it would be a lot more better if you change this into

v_name varchar2(255);
v_sal number;

that make your code is not dependent to any table until run time.

Maybe you can solve your above problems with this REF CURSOR syntax example, hopefully be useful for you..

DECLARE
cur_ar VARCHAR2 (32767)
:= ‘SELECT *
FROM vat.mpp_vat_ar_trx_int_v
WHERE segment8 BETWEEN ”’
|| condition_start_date
|| ”’ AND ”’
|| condition_end_date
|| ””;

TYPE cur_type IS REF CURSOR;

CV cur_type;
cur_temp1 vat.mpp_vat_ar_trx_int_v%ROWTYPE;
BEGIN
IF condition_source IS NOT NULL
THEN
cur_ar := cur_ar || ‘ AND org_id = ‘ || condition_source;
END IF;

OPEN CV FOR cur_ar;

LOOP
FETCH CV
INTO cur_temp1;

EXIT WHEN CV%NOTFOUND;

INSERT INTO vat.vat_ar_transaction_int
VALUES (vdata_import_code, cur_temp1.transaction_number,
cur_temp1.npwp, cur_temp1.customer_number,
cur_temp1.org_id, ‘A’, ‘2′, ‘1′, ‘1′, ‘000′,
cur_temp1.segment6, cur_temp1.segment7,
cur_temp1.segment8, cur_temp1.segment9,
cur_temp1.segment10, cur_temp1.segment11,
cur_temp1.segment12, 0, 0, vcompany, user_id,
cur_temp1.segment17, cur_temp1.segment18, cur_temp1.segment19,
cur_temp1.segment20, cur_temp1.segment21,
cur_temp1.segment22, cur_temp1.segment23,
cur_temp1.segment24, cur_temp1.segment25,
cur_temp1.segment26, cur_temp1.segment27,
cur_temp1.segment28, cur_temp1.segment29,
cur_temp1.segment30, cur_temp1.segment31,
cur_temp1.segment32, cur_temp1.segment33,
cur_temp1.segment34, cur_temp1.segment35,
cur_temp1.segment36, cur_temp1.segment37,
cur_temp1.segment38, cur_temp1.segment39,
cur_temp1.segment40, cur_temp1.segment41,
cur_temp1.segment42, cur_temp1.segment43,
cur_temp1.segment44, cur_temp1.segment45,
cur_temp1.segment46, cur_temp1.segment47,
cur_temp1.segment48, cur_temp1.segment49,
cur_temp1.segment50, vdate, vuser, vdate, vuser, NULL,
‘N’);

END LOOP;

CLOSE CV;

END;

This example, though using IMMEDIATE, doesn’t solve anything, as the table name isn’t really variable, but known indirectly at compile type via the variable ‘table_name’.

The %rowtype is bound to table_name, which is (or should be), by problem defintion, unknown. We cannot use the %rowtype on a REF CURSOR, leaving us with the problem unsolved, as

“select * from table_name”

will not be parsable for any “table_name”s as we cannot resolve ‘*’ into any known %rowtype.

Feuerstein has a discussion of “Dynamic PL/SQL” in his “Oracle PL/SQL Programming”. As far as I can see, this (very tedious) method is the only way of solving the problem in a generic way.

If somebody has a better idea, please mail me!
