I have written this below code. The logic behind the code is, Delete the duplicate record from a table, and delete those record from other 7 table based on the SL_NUMBER.
But Problem is After delete the duplicate record When I have use Below statement
RETURNING SL_NUMBER BULK COLLECT INTO rec_sl_number;
This statement unable to return approx 40 Lakhs SL_NUMBER
DECLARE rec_sl_number dbms_sql.number_table; BEGIN
id name plan code 1 sam normal 5 1 sam normal 6 1 sam special 5 1 sam Special 6
I need to delete data in such a way that one entry with normal and one entry with special plan should remain and should be with different code. Does not matter whether normal stays with 5 or 6 code.
I tried with rowid but it deletes either both normal or both special or returns same code for normal and special.

like this am having multiple times the duplicates.
I have written the below query to delete the duplicate records. But it is deleting only one record (if we have 5 duplicates it is deleting only 1 ). But I am looking to delete if we have 5 duplicates need to delete 4 duplicates and keep 1 record in the table.
query which am using to delete the duplicates is
DELETE FROM Table1 a WHERE ROWID IN (SELECT MAX(ROWID) FROM Table2 b WHERE a.ID = b.ID);
it is deleting only one row but I want to delete 4 records out of 5 and keep one record.
The requirement is I have a table (TAB1), wherein I have 3 columns, ID, LID and STATUS.
The value in ID column = ID_SEQ.NEXTVAL,and LID will be either 0 or 1 and the possible values for STATUS are 'ED','CP', NULL. The ID column is not suppose to have duplicate values, but there is no check on the table for the same.
Someone has updated the existing data and ID column is containing duplicate values. Wherever LID = 0 and STATUS = NULL and if only if ID is duplicated then the ID_SEQ.NEXTVAL has to be assigned to ID field, so that there are no more duplicate values.
CREATE TABLE tab1 (id NUMBER , lid NUMBER, status VARCHAR2(10));
Existing Data ------------------ INSERT INTO tab1 VALUES (1,0, 'ED'); INSERT INTO tab1 VALUES (1,0, 'CP'); INSERT INTO tab1 VALUES (1,0, NULL); INSERT INTO tab1 VALUES (1,0, NULL); INSERT INTO tab1 VALUES (1,0, NULL); INSERT INTO tab1 VALUES (1,0, NULL);
