SQL & PL/SQL :: Cartesian Selects After Update From 10.0.2.0.3 To 10.0.2.0.5?
Jul 27, 2010
we just installed the patch 10.0.2.0.5 on a 10.0.2.0.3 database and some selects didn't work as before. While changing the select clause, there are different counts.
There are 3 tables:
Detail_1 => MASTER_1 <= Detail_2
MASTER_1 has a primary and an unique Key. The 2 detail tables have FK. Now when selecting only columns from the detail tables (joined with master) we get cartesian selects. If i use one column of the master table in the select clause everything is fine.
SQL> select l.state,l.country as DestinationCountry,to_char(t.datefrom,'yyyy-mm' )as Year_Month,avg(hf.sat_rate)as AverageSatisfactionRate from holiday_fact hf,t ime1 t,location l where l.state=(select l.state from location l where l.country= 'Australia')and hf.loc_id=l.loc_id and hf.dest_id = l.loc_id and hf.date_from=t.
[Code]....
ERROR at line 1: ORA-01427: single-row subquery returns more than one rowplz tell my mistake.
i am trying to get the states only in Australia and rest of the attributes as they are.
The requirement is to replicate the bu_id records with bu_id=0 as bu_id=414545 ( there is no lookup available) so the same table should act as a lookup table to populate bu_id for the records where bu_id=0
i.e., here it will replicate for the sku set with bu_id value=0
select a.ccn,b.bu_id,a.sku,b.sku from test_item_bu_id a , ( select distinct ccn,sku_num, bu_id from test_item_bu_id where bu_id in (414545) and CCN in ('M10000') ) b where a.bu_id = 0 and a.sku <> b.sku and a.ccn= b.ccn
How can we avoid the last record, i.e., SKU=600-11437 since it is already having bu_id no need to replicate it, but it is getting replicated since the extra record with bu_id=0 exist for the same sku.
must generate a Cartesian join, but I do not know why it happens. dt.debtorkey, cl.clientkey, inv.invoicekey, ag.agingkey are primary keys of each table. The problem is: I got same tuple for 8 times.
At my Workplace we have a large Orcle 11g Database with 30 different tables for production control issues.I try to get a couple of different information from the database, so i started with SQL Query's, but for this problem i was not able to write an working query.
In this case i have 2 tables:
Table 1: ID ;ORDER_NR ;DESCRIPTION ;CREATE_DATE 1 ;A500236 ;CLEAN HOUSE ;02/20/2012 2 ;A623555 ;REPAIR CAR ;01/10/2012 3 ;A866944 ;MAINTAIN EQUIPMENT ;02/11/2012
And the result of my Query should look like this: ORDER_NR;DESCRIPTION ;CREATE_DATE;A_STAT_AGE;R_STAT_AGE;U_STAT_AGE A500236;CLEAN HOUSE ;02/20/2012 ;5 ;3 ;1 A623555;REPAIR CAR ;01/10/2012 ;42 ;39 ;38 A866944;MAINTAIN EQUIPMENT ;02/11/2012 ;15 ;4 ;3
The age of my query result should be calculated from the Create date of the Order.I want to know 2 things, one is how old was the Order when they reached that status A, R and U.The second this ist, how long did the order remain on the stat A,R and U (and if possible all other status also)It could happend that not each order reaches each status, so it ca go directly from A to you in this case i want display a wildcard in this row/column
how does this query execute? what kind of a query is this called?
mysql> select ename,(select dname from dept where deptno=e.deptno ) as dname -> from emp e;
+--------+------------+ | ename | dname | +--------+------------+ | SMITH | RESEARCH | | ALLEN | SALES | | WARD | SALES | | JONES | RESEARCH | | MARTIN | SALES | | BLAKE | SALES | | CLARK | ACCOUNTING | | SCOTT | RESEARCH | | KING | ACCOUNTING | | TURNER | SALES | | ADAMS | RESEARCH | | JAMES | SALES | | FORD | RESEARCH | | MILLER | ACCOUNTING | +--------+------------+ 14 rows in set (0.00 sec)
Having production system: 11.2.0.1 on Windows Server x64 Test system: 9.2.0.1 on Windows XP
Problem preface: to get all unique CASEID which should be checked up by biometric system.What i should check - all CASEs for different PERSONs having same PHONEs at least among one phone type (1..4).Real table contains little bit more than 10 million records.I made test scripts.
Below the DDL for test table creation: ------------------------------------------ -- Create CASEINFO test table ------------------------------------------ DROP TABLE CASEINFO; CREATE TABLE CASEINFO
[code]...
Below i've put SQL/DLL to make test data.number of records inserted 2 millions. PERSON_COUNT := #/8; ------------------------------------------ -- fill CASEINFO with sample data ------------------------------------------ DECLARE I INTEGER;
[code]...
Below SQL select to check the data in created table. ------------------------------------------ -- Check test data counters ------------------------------------------ SELECT 'TOTAL',count(*) from CASEINFO UNION ALL SELECT 'LEGAL',count(*) from CASEINFO where
[code]...
The PROBLEM is that i am experiencing HUGE perfomance problems on both test and production systems with that query:
select distinct b.caseid from CASEINFO a, CASEINFO b where (a.person<>b.person) and (a.sex=b.sex) and ( (a.phone1=b.phone1) or (a.phone1=b.phone2) or (a.phone1=b.phone3) or
[code]...
This query takes almost 90 minutes to execute.And i do not know how to avoid this.Full SQL file to make test attached.
I'm trying to use SYSTDATE in a WHERE clause of nested SELECTS..I want to select a range of info from two days back from today until today (or time it is being run). But when I run this, it says I have a missing expression...
SELECT XXXX FROM XXXX WHERE DATE BETWEEN TO_DATE(SELECT TO_CHAR(SYSDATE, 'YYYYMMDD') -2) AND TO_DATE(SELECT TO_CHAR(SYSDATE, 'YYYYMMDD HH24:MI:SS'))
I was practicing on Recursive Subquery Factoring based on oracle examples available in the documentation URL....I was working on an example which prints the hierarchy of each manager with his/her related employees. Here is how I proceed.
WITH tmptab(empId, mgrId, lvl) AS ( SELECT employee_id, manager_id, 0 lvl FROM employees WHERE manager_id IS NULL UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees, tmptab WHERE (manager_id = empId) [code]....
107 rows selected.
SQL> However, by accident, I noticed that if instead of putting a comma between the table names I put CROSS JOIN, the very same query behaves differently.That is, if instead of writing
UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees, tmptab WHERE (manager_id = empId)I write . . . UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees CROSS JOIN tmptab WHERE (manager_id = empId)I get the following error message ERROR at line 4: ORA-32044: cycle detected while executing recursive WITH query
I remember, oracle supports both comme notation and CROSS JOIN for Cartesian product (= cross product). For example
SQL> WITH tmptab1 AS 2 ( 3 SELECT 'a1' AS colval FROM DUAL UNION ALL 4 SELECT 'a2' AS colval FROM DUAL UNION ALL 5 SELECT 'a3' AS colval FROM DUAL 6 ), [code]....
SQL> So if both comma notated and CROSS JOIN have the same semantic, why I get a cycle for the above mentioned recursive subquery factoring whereas the very same query works pretty well with comma between the table names instead of CROSS JOIN? Because if a cycle is detected (ancestor = current element) this means that the product with CROSS JOIN notation is generating some duplicates which are absent in the result of the comma notated Cartesian product.
The Oracle DB in question is 11.2.0.1, x64, Server 2008.I also have a SQL Server 2005 database that runs a third party product, "PaperVision", which we use to manage documents of various kinds. This SQL Server server is also Win 2008, x64.Now, on the server that runs SQL Server, I have a simple view which is defined as such :
This view works great from the SQL Server side. I also created a database link from Oracle to the SQL Server machine, and it also works great.It is defined as such :
CREATE PUBLIC DATABASE LINK PVE_SQLSERVER CONNECT TO EVP_PVE_USER IDENTIFIED BY <PWD> USING 'PVE_SQLSERVER';
Where EVP_PVE_USER is a user created on the SQL Server machine with rights to select from this view.I know it works because I get results with a sql command like :
select * from VW_PVE_DOCS_1_1@PVE_SQLSERVER;
I also created a view on the Oracle server that refines this information. It is defined as such :
CREATE OR REPLACE FORCE VIEW EVPDBA.VW_PVE_CONTRACTS_INALERT ( DOCID, EFFECTIVE_DATE, EXPIRATION_TYPE, ALERT_PERIOD_START, ALERT_PERIOD_END, ACRONYM, [code]....
This view also works fine, i.e., I can select * from it from the sql command line.Now, the problem comes in when I need to run a procedure that processes this view every night and/or week.I have stripped everything out of this procedure that is not relevant, and it is defined as such for this forum :
CREATE OR REPLACE PROCEDURE EVPDBA.TESTME is tnum number := 0; begin select count(*) into tnum from VW_PVE_CONTRACTS_INALERT; end; /
If I execute this procedure from the sql command line, all is well.When I run it from a scheduler job, I get
ORA-01010: invalid OCI operation ORA-02063: preceding line from PVE_SQLSERVER ORA-06512: at "EVPDBA.TESTME", line 5 ORA-06512: at line 1 ORA-06512: at "SYS.DBMS_ISCHED", line 185 ORA-06512: at "SYS.DBMS_SCHEDULER", line 486 ORA-06512: at line 1
I am aware that DBMS_SCHEDULER performs a commit when scheduling a job, however, this is not scheduled from a trigger.I scoured the forums and have found a few things that seemed relevant, but not much. One had to do with the version of the JDBC driver between two Oracle databases, but I wonder if the age difference between Oracle 11 and SQL Server 2005 (Express) might be an issue. The fact that all command line select statements and running the procedure work fine implies to me that there is an additional issue raised due to the scheduler.
The other posts I found talked about performing a commit just before any select that ultimately pulls across a db link. I did this, and still no luck.One other useful fact - the job appeared to run succesfully at 5am, yet trying again at 8am threw the error, so it may be sporadic. (Although during regular daytime hours it is a very repeatable error).
I am looking into reformatting things to use the older DBMS_JOB, however, I really like the log history of job details and other functionality available with SCHEDULER.
I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?
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 want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "table %s.%s is mutating, trigger/function may not see it".
*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.
CREATE OR REPLACE TRIGGER set_date_end BEFORE INSERT OR UPDATE OF issued ON shares_amount FOR EACH ROW DECLARE BEGIN INSERT INTO shares_amount(date_end) VALUES(SYSDATE); END set_date_end; /
i am reading the columns value from different table but i want to update it with single update statement. such as how to update multiple columns (50 columns) of table with single update statement .. is there any sql statement available i know it how to do with pl/sql.
insert into test_compound values ('user1','1',systimestamp); insert into test_compound values ('user2','2',systimestamp-4); insert into test_compound values ('user3','3',systimestamp-6);
CREATE OR REPLACE TRIGGER trigger_test FOR UPDATE ON test_compound COMPOUND TRIGGER TYPE t_tab IS TABLE OF VARCHAR2(50); l_tab t_tab := t_tab(); [code].......
When I execute :
update test_compound set last_updated_on=systimestamp where userid='user1' and app='1';
The trigger should update the first row and all the data from test_compound table where userid='user1'. Maybe the problem is that updating the same table inside the trigger is firing in a recursive way the trigger.
I have a column "empno" in EMP table and "deptno" in DEPT table . I want to update both the columns with single UPDATE statement. With out a creation of stored procedure or view(updating it through view).
I have an employee table that has a paygrp_id that will be used for my subset of employees. For all the employees that have the paygrp_id = 10212 on the employee table I need to update the workbrain_user table to set the flag wbu_cansee_self to 'N'. The join between the employee table and the workbrain_user table is the emp_id.I get the following error when I run this cursor.
[error] Error on line 0 DECLARE CURSOR wbuFlag_cur IS SELECT e.emp_fullname, e.paygrp_id,wbu.WBU_CANS [code]...
I have to update a table by getting values from two other tables. While doing that the inner query returns more than one value. I am not sure how to implement the logic without returning more than one row in sub query.
My query: update buf_office_str o set o.manager_ident = (select sp.ident from se2_r_src_sourceperson sp , (select distinct director_name, team_name from buf_sales_dump )t where SP.SRCNAME = upper(substr(t.director_name,instr(t.director_name,' ')+1,length(t.director_name))||', '||substr(t.director_name,1,instr(t.director_name,' ')-1 ) ) and o.office_descr = t.team_name )
Basically the query gets the manager id from sp table where sp.srcname = t.team-name. The office_descr should be equal to the team_name.
This is the logic I am working towards:
For each office, i get the office_descr and get corresponding team_name. Match the team's director_name (from table t) with the sp.name and return the employee's id (sp.ident) for that office_descr. I need to update all 50 offices with corresponding managerid for that office in buf_office_str table.
Is it possible to get done in one update? Or, does this need a plsql proc to do this logic.
ID DETAILS --- -------- 100 The ship has left san diego http:/localhost/icons/sandiego.png to okinawa on nov 10, 2011.
I need to update the record(id = 100) by replacing the url "http:/localhost/icons/sandiego.png" with "http:/localhost/icons/okinawa.png".
I need a procedure where I will pass the ID value, replace string(i.e http:/localhost/icons/sandiego.png) and replace with string (ie. http:/localhost/icons/okinawa.png).
In a pl/sql procedure, when I am doing an update, I need the old value to be returned and stored in a local variable, so that the same can be used for future purpose.
Note : I know the "OLD:" option is present when we use TRIGGER, but in my case , the table I am updating is a old table and I am not permitted to create a trigger for it.
I have one table with one row with some coefficients. If I update a coefficient from my table I want to be updated all the rows from another table. I've made a trigger but in the second table I have a column for example TOTAL and I want that column to be multiplied with my new coefficient, and I want this for every row in the second table. How I can select that total column in the trigger for every single row and update it?
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';
