The requirement is, the combination of col1,col2,col3 and col4 should always be unique, and wherever the col1, col2,col3 are same then col4 should be the sequence, starting from 1. Likewise the data should be updated back to the table.I'm able to do this using PL/SQL. Can I do the same using a single update statement?
I used decode & pivot insert for this,but the result is a failure.
SQL>INSERT INTO test22 (no,name) SELECT DECODE(col1,'n',col2),DECODE(col1,'name',col2) FROM test22p;
SQL> sno sname -------- 1 null null arun
AND
SQL> INSERT ALL 2 INTO test22 VALUES(no) 3 INTO test22 VALUES(name) 4 SELECT DECODE(col1,'n',col2),DECODE(col1,'name',col2) FROM test22p; INTO test22 VALUES(name) * ERROR at line 3: ORA-00904: "NAME": invalid identifier

I am exploring the differences between OBJECT & RECORD. As i am still in process of learning, I found that both are structures which basically groups elements of different datatypes or columns of different datatypes, one is used in SQL and other is used in PL/SQL. Below i am trying to insert data into an table of type object but i am unsuccessful.
CREATE OR REPLACE type sam as OBJECT ( v1 NUMBER, v2 VARCHAR2(20 CHAR) );
---Nested Table--- create or replace type t_sam as table of sam; --Inserting data---- insert into table(t_sam) values(sam(10,'Dsouza')); Error Message: [code]........
I am trying to insert huge data into another huge table which is almost taking around 2-3 hrs. See my below query
INSERT /*+ APPEND *//*+ NOLOGGING */ INTO DB1.Table1 SELECT * FROM DB2.Table2 ; COMMIT;

I have a form that has one text box in it, and I want this value to be inserted into a table called Staff Name, which has only one column, but im unsure as to how I would get my SQL statement to pick up this value.

Our application is using a two instance, one for the live active data and the other for the reports data. We have a process which moves the data from the live instance to reports instance every night. In a single db environment the process is working without any issues. However when we move to the RAC environment the reports db's (insert) in large table get locked and we are unable to insert data to the reports db.
What we are performing is:
Insert into my_table_rpt select * from may_table_live@db_link_to_livedb;
Issues:
my_table_rpt get locked
We have found the workaround by disable locking in destination and subsequent to the insert enable locking
ALTER TABLE my_table_rpt DISABLE TABLE LOCK;
Insert the data to the reports database table
Then
ALTER TABLE my_table_rpt ENABLE TABLE LOCK
Question:
Why does the large destination table (my_table_rpt) get locked in the RAC environment?
I want know how the values in view DBA_FEATURE_USAGE_STATISTICS gets updated i have already checked the metadata of this view but unable to find how / when the values are being updated.
I have multiple project databases where their tables are similar. I wanted to know just a single date from each project databases is modified/updated. If I run a query like select * from component order by eng_proj_id, chg_date desc then it will return many records sorted by their eng_proj_id and chg_date in their descending but I only need just a single record with last update from each project databases.

I have the manipulated data on temporary table name "tempdata" and i want to display it in to my report, I am using the temporary table, and also call report from the same session on which data is updated on temporary table. but its still not showing data on the report, I think this is the session problem of the form but i also call report from the same form , so the session should b same for both the report as well as for the form, so y don't the report show the temporary table data.
There are two tables like I posted below.I want a SQL query which selects all the rows from TABLE A which are not present in TABLE B. Also the select statement should pick all those rows which has updated value of COL_A2 in TABLE A.
TABLE A COL_A1COL_A2
AAAMOBILE BBBTABLET CCCDESKTOP DDDUNKNOWN
TABLE B COL_B1COL_B2
AAAMOBILE BBBUNKNOWN CCCDESKTOP
The select statement should return following rows from TABLE A
when the tables are updated, the following detals must be correct to ensure that the links in the affected tables are in place.
PLUPDATE_NEW(PLUP_SAVE_SEQ field value) must be the same with PLUPDATE_BENEF_NEW (PLUP_NEW_BENEF_SAVE_SEQ field value) PLUPDATE_OLD(PLUP_SAVE_SEQ field value) must be the same with PLUPDATE_BENEF_OLD (PLUP_OLD_BENEF_SAVE_SEQ field value)?

i tried this code, what should i do in the link for this tables?
