end UPD_emp_all;
CREATE OR REPLACE PACKAGE BODY UPD_emp_All AS
PROCEDURE UPD_emp(emp_rec in Varry_emp) is
BEGIN
MERGE INTO emp T
Using emp_rec V
ON (T.emp_id= V.emp_id and
     T.emp_dept=V.emp_dept)
WHEN MATCHED THEN
UPDATE set
T.col1 = v.col1,

Thanks Avinash.
Even if i declare a variable of same type as emp_rec,
inseide my procedure, how do i assign my new_array with values of the ones that has been passed through a parameter?
Plz help..
I get an ARRAY as a parameter in the procedure.
Need to use it to merge with a Table.
CREATE OR REPLACE PACKAGE UPD_Pemp_all AS
TYPE Varry_emp IS TABLE OF emp%ROWTYPE;
PROCEDURE UPD_emp(emp_rec in Varry_emp);
end UPD_PATCH;
CREATE OR REPLACE PACKAGE BODY UPD_emp_ALL AS
PROCEDURE UPD_emp(emp_rec in Varry_emp) is
BEGIN
FORALL I IN emp_rec.first..emp_rec.last
MERGE INTO emp T
Using dual V (also tried using select * from Table(emp_rec))
ON (T.emp_id= emp_rec(i).emp_id and
one more cond)
WHEN MATCHED THEN
UPDATE set
t.cols=emp_rec(i).cols
WHEN NOT MATCHED THEN
Insert (stuff here)
END UPD_PASTATUS;
END UPD_PATCH;
The FOR ALL is not working, thows erros cannot bind etc.. I am Using Oracle 10g Rel2
Thanks for any help.
