SQL & PL/SQL :: Find Locked Tables In Hierarchy
Feb 1, 2012
Is it possible to find the locked objects in hierarchical order. Consider the below example
--Connect to scott schema
create table block_session(a NUMBER, b VARCHAR2(100))
/
insert into block_session select rownum,rownum*10 from dual connect by level<=10
/
COMMIT
/
GRANT ALL ON block_session to HR
/
update scott.block_session
SET a=10
where b=10
[code]......
Is it possible to get all locked table details in hierarchical order?

I am on database 10.2.0.5, windows x64.
A developer calls me and tells me there are locks on 3 tables, and the locks are not released. So I run this to see which objects are locked by which session
select vlo.object_id, vlo.session_id, vlo.oracle_username, vlo.process
, DECODE(vlo.LOCKED_MODE, 0,'NONE', 1,'NULL', 2,'ROW SHARE', 3,'ROW EXCLUSIVE', 4,'SHARE', 5,'SHARE ROW EXCLUSIVE', 6,'EXCLUSIVE', NULL) LOCK_MODE
, do.owner, do.object_name, do.object_type
[code]...
When I run the query later, I sometimes get another session, but the lock stays. It seems here, that I am catching the same SID on new sessions, but it is probably a different serial # than the original session locking the table rows.
I get nothing from
select * from dba_waiters;
select * from dba_blockers;
Now why are those 3 tables row locked on some rows and I can't find the session responsible? The developer tells me his application crashed and the rows are locked since. So far ( keep in mind I am not a locking expert) the only way I found to release the locks is a DB bounce, its a test DB so no biggy.

I need to find all "report to" supervisors in a hierarchical chain. A binary search won't work, as each level may contain > 2 supervisors. Example:
1
2 3 4
5 6 7 8 9
10
10 reports to 9
9 reports to 4
5 and 6 report to 2
7 and 8 report to 3
2, 3 and 4 report to 1
Result for all reporting to 1 would be a table containing 2, 3, 4, 5, 6, 7, 8, 9, 10 (order is unimportant!).
I think I need to use recursion. I can do this in C; need code for PL/SQL??? (I can't get the "tree" to display well!)

I have two tables A with columns a.key, a.location_code, a.status and a.first_name and table B with cols b.key, b.location_code, b.status and b.first_name.
I want to find the missing records between the two tables and as well check whether each column is populated correctly. That is if u take a record with id 1 check if loc_code is same in both the tables and if they are different, insert the key and first record column and second record column into a new table. And similarly if there is no record wiht that particular id in the second table, insert the record.
For missing records in the sense for records which are present in A but not in B, am using
Select a.key_no, a.loc_code, b.loc_code
from A,B
where a.key_no=b.key_no(+)
and b.key_no IS NULL
But the problem is I need to put some constraints on the B table like b.status='Married'and b.loc_code='CA'. When am using this condition in the above query, it's throwing me error saying cannot use outer join operator in and or or.And I could not figure out how to check for the columns being populated correctly between the two tables and at the same time check for missing ones

I would like to be able to sort through a schema's tables to find if particular vendor numbers exist. The decode cross tab works fine, except that it needs static data for each table. How can I code a PL/SQL to populate the table_name and give a count for each row? See example below:
col table_name format a15
set numwidth 10
set lines 1000
set pages 50
select b1.table_name,
count(case when a.vendor='86444' then 1 else null end) "86444",
count(case when a.vendor='86445' then 1 else null end) "86445",
count(case when a.vendor='86469' then 1 else null end) "86469",
count(case when a.vendor='86470' then 1 else null end) "86470",
[code]........

We want to find out difference of data for some tables between current day & previous day. We can use query with minus operation but it will take lot of time since table size is in range from 200 to 500 GB. We have to do this exercise every day.

Insert into PROFILE
(INSTANCE, PROFILENAME, USER_DATA, UPDATE_DATE)
Values
(138, 'Test A', 'SRC!-1,ARCHIVE_OPT!-1,DATE_FIELD!155,DATE_RULE!1,DISTINCT!1', TO_DATE('01/20/2005 13:35:33', 'MM/DD/YYYY HH24:MI:SS'));
/
Insert into RULES
(ID, NAME)
Values
(155, 'DATE_TEST');
I want a code something of this sort:
select profilename from PROFILE where user_data like '%DATE_RULE!115%';
Output will be "Test A".Now, this is just a single value from RULES table used to find the data of PROFILE table.I will have to run the query on multiple values of RULES tables to find records containing a string format of sort "DATE_RULE!<rule_no>". How to search on WILD CARDs like these?
