I am using JDBC to run a few queries from my Java program (multi-threaded one).I am facing an issue where a select statement is blocking a delete statement. From the java code point of view, there are 2 different threads accessing the same tables (whith different DB connection objects).
When the block occurs (which i was able to find out from the java thread dump that there is a lock on oracle), the below is the output:
SQL> SELECT TO_CHAR(sysdate, 'DD-MON-YYYY HH24:MI:SS') 2 || ' User '||s1.username || '@' || s1.machine 3 || ' ( SID= ' || s1.sid || ' ) with the statement: ' || sqlt2.sql_text ||' is blocking the SQL statement on '|| s2.username || '@' 4 5 || s2.machine || ' ( SID=' || s2.sid || ' ) blocked SQL -> ' 6 ||sqlt1.sql_text AS blocking_status FROM v$lock l1, v$session s1, v$lock l2 , 7 v$session s2,v$sql sqlt1, v$sql sqlt2 8 WHERE s1.sid =l1.sid 9 AND s2.sid =l2.sid AND sqlt1.sql_id= s2.sql_id AND sqlt2.sql_id= s1.prev_sql_id AND l1.BLOCK =1 10 AND l2.request > 0 AND l1.id1 = l2.id1 AND l2.id2 = l2.id2; [code]...
From the above it can be seen that a select statement is blocking a delete. Unless the select is select for Update, it should not block other statements is not it ?

I need to delete all the registers where the table 1 does join with table 2 in 3 fields... for example:
delete taba1 t1 where t1.campo1 in ( select distinct(tr.campo1) from tabla1 tr, tabla2 t2 where t2.error = 0 tr.campo1 = t2.campo1 and tr.campo2 = t2.campo2
I'm having some trouble writing this query using a decode statement within a join. First, lets say I have two tables. Table A has the fields 'Baseline', 'NAD', 'Null', and 'Harn'. Table B has the fields 'Null', 'NAD', and 'Harn'. I want to join these tables together by these fields to return their ID's. Because table B doesn't have 'Baseline' to even have a match between the two tables, in Table A, we want to treat 'Baseline' as 'Harn', hence a decode statement. My query is below
Select ... ... ... From ... inner join oracle_srid_xref B on A.horizontal_datum = B.horizontal_datum and decode(A.horizontal_epoch, 'BASELINE', 'HARN', loc.horizontal_epoch ) = B.horizontal_epoch
I'm not getting the ID's where the horizontal_epoch was initially 'Baseline'
I've seen this example numerous places, and tried to implement it, but I keep getting an "invalid identifier" error message, despite the fact that I've got the table and column specifically identified.For instance, my query reads like:
UPDATE tbl1 SET tbl1.EMPID = (SELECT tbl2.EMPIDA FROM tbl2 WHERE LOWER(tbl1.EMAILCOL) = LOWER(tbl2.EMAILCOL2) ) WHERE tbl2.EMPIDA IN ('Z1O435','S8M4722','M0D5156') AND EXISTS (SELECT tbl2.EMPIDA FROM tbl2 WHERE tbl1.EMAILCOL= tbl2.EMAILCOL2 );
But I'll keep getting flagged at the tbl2.EMPIDA column reference. I have not tried this in SQL Plus, just in TOAD, but it seems to repeatedly fail.I have had to dump records to standalone Access tables and link back to perform the updates.
I am getting ORA-00933 after running below mentioned delete statement;
DELETE FROM REPOSITORY.MEDIASEGMENT MS INNER JOIN REPOSITORY.ROUTINGEVENT RE ON TRIM(MS.Segment_Key) = TRIM(RE.uuid) INNER JOIN REPOSITORY.TEMPCONTACT TC ON TRIM(RE.Contact_Key) = TRIM(TC.vduid) WHERE TC.CREATETIME BETWEEN (TO_DATE('04/24/2008 00:00:00','MM/DD/YYYY, HH24:MI:SS')) AND (TO_DATE('04/30/2008 23:59:00','MM/DD/YYYY, HH24:MI:SS'))
I have a session on a system here that has been stuck on a DELETE statement for a very long time and the session is pegging the CPU. Using TOAD here is the "current statement":
DELETE FROM WORKFLOW WHERE ID = :B1
ID is the primary key of the table.Here are some relevant stats, also from TOAD's session browser:
Elapsed time = 35507986900 CPU time = 35531815481 Buffer gets = 972040769 Disk reads = 951289273 Executions = 71462
I'm not sure I understand "executions" because from the information I have from the people who initiated this, this particular delete should only be occurring 30 times... maybe that stat means something other than what I think it does.I also ran a trace for 30 seconds using:
TKPROF: Release 11.2.0.1.0 - Development on Wed Feb 27 04:04:50 2013 Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved. [root@localhost trace]#
The resulting file is attached. Now the offending query in the tkprof, based on my interpretation, is the select from the CMTE00 table, which contains 2344482 rows and no index on the workflow_id column. The relationship between CMTE00 and WORKFLOW tables are 1 to 1. There is a foreign key on CMTE00 pointing to the primary key of WORKFLOW which is what I assume initiated this query - I assume this is oracle checking the referential integrity since our code is not executing that statement. Also of interest, prior to this delete statement, the corresponding entry in CMTE00 was deleted in the same transaction. Google searching "db scattered file read" lead me to one of your (Don - if you read this) articles and appears to indicate that individual blocks are being fetched off the disk and this is what is taking up all the time.
DELETE FROM sre_t WHERE TO_CHAR(end_dt,'yyyy')<'2000' or TO_CHAR(start_dt)<'yyyy')<'2000';
It's executing for 15 to 20 minutes after that i got the error "session timed out"..The table is having four crore records.The delete statement is deleting 12,00000 records.
In my code I am using delete statement which is taking too much time to execute.
Statement is as follow:
DELETE FROM TRADE_ORDER_EMP_ALLOCATION T WHERE (ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT) IN (SELECT ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT FROM LOAD_TRADE_ORDER WHERE IND_IS_BAD_RECORD='N');
Every column in "IN" clause and select clause is containing index on it
Every time no of rows which to be deleted is vary (May be in hundred ,thousand or hundred thousand )so that I am Unable to use "BITMAP" index on the table "LOAD_TRADE_ORDER" column "IND_IS_BAD_RECORD" though it is containing distinct record in it.
Even table "TRADE_ORDER_EMP_ALLOCATION" is containing "RANGE" PARTITION over it on the column "ARTEMIS_SOURCE_SYSTEM_ID". With this I am enclosing table scripts with Indexes and Partitions over it.
way for fast execution in of above delete statement?
UPDATE t_tt_hours a SET a.sak_request = ( SELECT b.sak_request FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a SET a.sak_request = ( SELECT b.sak_request FROM t_requests b, co c WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.
I have to write a procedure that accepts schema name, table name and column value as parameters....I knew that i need to use metadata to do that deleting manually.
i want to know the difference between Left outer join Vs. Right outer join? Its like which join is safer to use or is there any recommendations to use any join?
HOW to use variable P_TMPLID in following statement
TYPE typ_unrecon IS TABLE OF REC_' || P_TMPLID ||'_UNRECON%ROWTYPE index by binary_integer;
because its throwing error while compiling
and also in statement FORALL i IN unrecondata.FIRST .. unrecondata.LAST SAVE EXCEPTIONS --STRSQL := ''; --STRSQL := ' INSERT INTO REC_' || P_TMPLID ||'_UNRECON VALUES ' || unrecondata(i); -- EXECUTE IMMEDIATE STRSQL; INSERT INTO REC_' || P_TMPLID ||'_UNRECON VALUES unrecondata(i);---throwing error on this statement commit; --dbms_output.put_line(unrecondata(2).TRANSID); EXCEPTION
In the following merge statement in the USINg clause...I am using a select stament of one schema WEDB.But that same select statement should take data from 30 schemeas and then check the condition below condition
ON(source.DNO = target.DNO AND source.BNO=target.BNO);
I thought that using UNIONALL for select statement of the schemas as below.
I want to create a query with only the junction of these two queries:
- select id_utilizador,nbeneficiario,nome from adm_utilizadores a WHERE exists ( select 1 from adm_util_grupos b where a.id_utilizador = b.id_utilizador and b.id_grupo = '1') ;
- SELECT b.*,rownum as row_num FROM ADM_UTILIZADORES b ORDER BY $sidx $sord WHERE row_num BETWEEN $start AND $end";
Virtually want id_utilizador, nome, and nbeneficiario, I can get the first query, ordered me returning the first 10.
I have 2 tables SEC_MASTER_HISTA and SEC_MASTER_HISTB.
Now, I need to compare the data of the two tables column-wise.
Ideally the 2 tables should have the same security_alias values but in my case they do not as the two tables belong to 2 diff client models. There is however a main SECURITY_MASTERA and SECURITY_MASTERB tables which have the security_alias recorded and a primary_asset_id column value which can act as a link between SEC_MASTER_HISTA and SEC_MASTER_HISTB. But, I have not been able to figure out the exact query which will be ideal.
Attached are the table structures and the data it contains.
Note: I need to compare the Coupon and Freq column values of SEC_MASTER_HISTA and SEC_MASTER_HISTB.
im trying to update a column in the employee table with the value "YES". Im getting an error message saying im missing a SET statement from this code below:
update e SET e.review='YES' from employee inner join rentals r on e.employee_id=r.employee_id inner join job j on e.job_id=j.job_id where r.plate ='FY06WNT' and j.function !='MANAGER' and j.function !='PRESIDENT';
UPDATE dev10 SET c3 = dev12.c1 FROM dev10 INNER JOIN dev11 ON dev11.c3 = dev10.c1 CROSS JOIN dev12 WHERE (dev11.c2 LIKE 'BBBBBB') AND (dev12.c2 LIKE 'FFFFFF') / but, Oracle, what should we do new?
