Problem in Bulk collect

Question

Hi ,
I have declared a cursor with bulk collect. I have to insert only 2 columns values from tableA to TableB. The number of columns in tableA and TableB are not equal.
DECLARE
CURSOR c1                                    
IS
SELECT COLUMN1,COLUMN2,COLUMN3,COLUMN5 FROM TABLEA WHERE COLUMNS1='XXXXXXXX';
TYPE Cust_tab IS TABLE OF C1%ROWTYPE;
Custs Cust_tab;
BEGIN
     OPEN c1;
LOOP
     FETCH c1 BULK COLLECT INTO Custs LIMIT 100;
EXIT WHEN c1%NOTFOUND;               
     END LOOP;
     FORALL i IN 1 .. Custs.COUNT
SAVE EXCEPTIONS
INSERT into TABLEB(COL1,COL2,COL3,COL5) VALUES (Custs(i).COLUMN1,Custs(i).COLUMN2,Custs(i).COLUMN3,Custs(i).COLUMN5);
END ;
Iam getting an error as
ERROR at line 16:
ORA-06550: line 16, column 66:

Please let me know how to get out of the error.

Answer 1

INSERT into TABLEB(COL1,COL2,COL3,COL5)
SELECT COLUMN1,COLUMN2,COLUMN3,COLUMN5 FROM TABLEA WHERE COLUMNS1='XXXXXXXX';
works like a charm. Moreover: it SCALES!!
There is no reason in this case to use BULK COLLECT.
You should only use PL/SQL if you can't do it using SQL.
You can do it using SQL: you should use SQL.
Other than that: just read the error message, realize you can't directly use a collection involved in a fetch, just set up an extra collection and assign the old collection to the new.
The code is wrong anyway, as it doesn't allow for more than one fetch.
