I have taken the export backup of a table using the following command
userid=system/manager@DBATEST
file=abc.dmp
log=abc.log
Tables=X.S_ORG_EXT_X
feedback=100000
buffer=10000000
[code]......
but on querying the table it shows the number of rows as
select count(*) from X.S_ORG_EXT_X;
COUNT(*)
----------
25656051
Explain why there is a mismatch in the count of the rows in the table.
how to logically connect two tables. Here is an example of what I'm trying to do:
HOSTS TABLE CPU TABLE
----------- ---------
ID HOST ID CPU
01 host1 01 proc01
02 host2 01 proc02
03 host3 02 proc01
02 proc02
02 proc03
02 proc04
03 proc01
Based on the above, I can see that 'host1' has 2 CPUs, 'host2' has 4 CPUs, and 'host3' has 1 CPU. What I'd like to do is create a query that would output:
HOST CPU
----------
host1 2
host2 4
host3 1
I'm looping through the hosts and passing the them into another query as bind variables. That's slow and cannot be the best way to do this. I'm aware that I need to using a GROUP BY HAVING COUNT, but that doesn't seem to be working. It tends to return the total count of all CPUs rather than CPUs per host.
I have a UNION query having 3 parts, 1st gets date, 2nd data and 3rd displays the formatted data count :WHERE clause of 2nd and 3rd queries are same.
Problem is that I an getting different record counts when I select the overall count of records given by the whole UNION query and when I run to count the records given by each query individually.First count. Here I am selecting the overall count of records given by the query :
select count(1)
from (
SELECT SUBSTR ( '0'
|| TO_CHAR (SYSDATE, 'MM/DD/YYYY')
|| TO_CHAR (SYSDATE, 'HH:MI:SS')
|| LPAD (' ', 180)
[code]...
This count is : 1751525 Second count. Now when I run to count the records given by each query individually, here is the result
select count(1) a
from (
SELECT SUBSTR ( '0'|| TO_CHAR (SYSDATE, 'MM/DD/YYYY') || TO_CHAR (SYSDATE, 'HH:MI:SS')
|| LPAD (' ', 180)|| chr(13), 1, 200 ) dtl_record from dual
select count(1) b from (
SELECT '1'
[code]...
why there is difference of 1 (1751526 - 1751526) in the count results.
Managed to confuse myself significantly. I essentially want to write a query to determine when two counts are the same using a subquery.
Eg:
R(x,y)
Select count(x)
from R
group by x;
Then I want to run another query to determine which x's have the same count value and output these corresponding x's.
We have a partitioned transaction table in our Datawarehouse environment which has the following partition strategy
SCHEME=DATE-HASH
GRAIN=DAILY
SUBGRAIN=NONE
HASH=8
FROM=31/12/2011
We recently had to delete data from the table. This was a simple delete statement with a where clause and without taking into consideration any partition/subpartition clauses. Post committing the delete we have a count mismatch problem with two queries in particular
select count(0) count_without_parallel FROM TRANSACTION_TABLE t;
--THIS RETRIEVES *15774811* ROWS
select /* parallel(t,default) */count(0) count_with_parallel FROM TRANSACTION_TABLE t+
--THIS RETRIEVES *15777617* ROWS WHICH IS THE ACTUAL EXPECTED COUNT.
I also ran the following just to summarize
select (select count_with_parallel from (
select /* parallel(t,default) */count(0) count_with_parallel FROM TRANSACTION_TABLE t))+
-
+(select count_without_parallel from (+
select count(0) count_without_parallel FROM TRANSACTION_TABLE t)) as false_difference
from dual;
The difference in *2806* rows as expected.To re-affirm my counts I ran
select /*+ parallel(t,default) */
'count_on_t',count(*) from TRANSACTION_TABLE t
group by 'count_on_t'
order by 1;
--THIS RETRIEVES *15777617* ROWS
Removing the parallel hint reverts back to the lesser count. Not sure what is wrong but something prevents the query from parsing the whole table and/or partitions and subpartitions.
I am trying to get a row count(*) for all the tables in my schema. The NUM_ROWS column in DBA_TABLES is not appropriate in this case because they are as good as the last analyze. So I need to get real time counts.
I tried the following code but I can't seem to catch my error.
DECLARE
l_sql varchar2(150);
cursor tablelist is
select table_name from dba_tables where owner = 'ME';
[Code]....
My expected results are :
TABLE_NAME ROW_COUNT
---------- ----------
User table
id | name
----------
2 | Harry
3 | Mary
Course_User table
summer_course_completed | winter_course_completed | user_id | attendance
------------------------------------------------------------------------
y | n | 2 | 20
y | n | 2 | 40
y | y | 2 | 30
n | n | 3 | 20
n | y | 3 | 60
I wish to list each student's name with the number of summer courses he has completed and the number of winter courses he has completed. I am trying this :
select u.name, count(*)
from user u, course_user cu
where u.id=cu.user_id and cu.summer_course_completed = 'y'
group by u.id;
but I can get only the number of summer courses OR the number of winter courses that each student has completed, but never both simultaneously, through a single query. Is there a way to do that ?
I believe I have a problem with the ASM Kernel rpm that I downloaded from Oracle OTN
my Linux OS is
[root@UKEDXDTMTDBS01A u01]# uname -r

So I downloaded the x3 ASM files required
[root@UKEDXDTMTDBS01A u01]# ls -ltr *.rpm

As you can see the install worked fine
rpm -Uvh oracleasm*.rpm

Am I doing something wrong -
I have made a simple form in which user will be entering his username and relevant password to get authorised. My issue is , if the user is entering wrong password for 3 times then both fields should get disabled. I did the form until the point where it checks wether the user is authorised or not. But how to give count on failure of passwords.
View 5 Replies View RelatedI have got another curly one with regard to Sql Loader. My original issue via [message #513696] was resolved. In summary, SQL Loader opens a comma delimited csv file and it is able to successfully populate the appropriate Oracle table. However, during the run to process each unique csv file, SQL Loader produces a both a .log file (indicating what transpired during the load) and a .bad file of the records from the csv file that where rejected by SQL Loader.
the users have requested that "is it possible to update a separate table of the summary results of what went wrong and what was right?" It just so happens that the csv file contains some summary records (rows) with processing audit infor...as the following .bad file wrote out....

1. The first record (starting in the 1st postion is "ModuleID") is a heading record in the csv file and can be disregarded.
2. The secord record (starting in the 1st postion is "No Module ID") is an error record in the csv file and can be disregarded.
3. The third record (starting in the 1st postion 3500B9880611170260179BFB, ) is a valid record, however, is was rejected as it is a duplicate of a preceeding record ...and the log indicates ...
Record 124: Rejected - Error on table PTLIVE.MODULE_CSV_LOADS.

4. The fourth record (starting in the 1st postion is ,,,,,,,,,,,
) is a blank record in the csv file and can be disregarded.
5. The fifth record (starting in the 1st postion is "Total Modules" has a value of 1602 which I need to capture to write into a separate table.
6. The sixth record (starting in the 1st postion is "Mis-reads" ) has a value of 1 which I need to capture to write into a separate table.
7. The last record in the csv file and can be disregarded.
The summary Oracle table is
CREATE TABLE PTLIVE.SUBMODULES_SUMMARY
( IMPORT_CSV_FILE_NAME VARCHAR2(256 ),
TOTAL_SUBMODULES_LOADED NUMBER (5),
TOTAL_SUBMODULES_MIS_READ NUMVER (5),
DATEIMPORTED DATE default SYSDATE
)
Now I would like to trap the value 1602 and load that into the Oracle column TOTAL_SUBMODULES_LOADED and the value 1 and load this into TOTAL_SUBMODULES_MIS_READ.
The name of the csv file is known and I can (as the previous [message #513696] resolved) simply use a SQL Loader control file command > IMPORT_ CSV_FILE_NAME CONSTANT "Batch_2011Jun29_TEST.csv".
I have a table
TAB1 with data
no name
1 abc
2 abc

now I would like to create a form with name counts as

I would like to create a datablock to display all the unique names, not sure where I should be writing the query to display unique names. I would like to create a textitem box to display the counts when the form is compiled, but not sure which trigger to use to write the query.
We have employee salary table which will have salary of an employee on daily basis (only working days). Below is the table structure:
CODEemp_salary
----------
emp_id NUMBER(15) NOT NULL
effective_date DATE NOT NULL
salary NUMBER(15) NOT NULL
Primary key - emp_id, effective_date..This table is yearly partitioned...I have to find out how long the salary is not changed for an employee from given date, and last salary. I am using below query to do this:
CODEWITH salary_tab AS
(SELECT effective_date, salary,
(CASE
WHEN (LAG (salary) OVER (PARTITION BY emp_id ORDER BY effective_date ASC) =
salary
[code]....
For emp_id 1, if we ran this query for 10/31/2011, then it has to compare the 10/31 salary with 10/29 and do the same until the salary mismatches. In this case, salary salary mismatch occurs on 10/20, so the stale salary period is from 10/31 to 10/21 which is 7 days.Below query will give that result:
CODE
WITH salary_tab AS
(SELECT effective_date, salary,
(CASE
WHEN (LAG (salary) OVER (PARTITION BY emp_id ORDER BY effective_date ASC) =
salary
[code]...
I've 2 identical tables of 300+ columns each,and each of table is having pk as combination of 2 fields.There are some fields where data is not matching. need a query which will use these two tables and return the following-
1. primary key columns
2. null value for fields where data is matching
3. data for columns where there is data mismatch.
I have installed oracle 10g version 10.2.0.4.0 on Windows 7 64 bit from the following link.
[URL].........
After login to SQL* plus, when i see the version, it shows as 10.2.0.3.0. Is this correct?
We had a new outsourcer who completed migration of 1 of our system running under Oracle10g-Solaris 10. We created an inventory script that will list all objects counts of SYS, SYSTEM and ORACLE and all other schemas. This script will be ran before (old server) and after migration (to new server). After migration to the new & bigger server, we noticed from the output of the inventory script for SYS/SYSTEM object counts had been reduced compared from the original/actual value (from the old server). Our outsourcer said that this is not an issue since SYS/SYSTEM objects are not transactional and cannot be controlled.
As we will conform that the migration was completed successfully by our new outsourcer.
We are trying insert records from a select query in to temporary table, some of the records is missing in the temporary table. The select statement is having multiple joins and union all which it little complex query. In simple terms the script contains 2 part 1st Part Insert in to temporary table 2nd part Select query with multiple joins, inline sub queries, unions and group by classes and conditions Eg. If we execute select statement alone it returns some count for example => 60000 After inserting into the temp table, in temp table the count is around 42000 why is the difference?
It is simple bulk inserts... insert in to temp table select * from xxx. also, there is no commit in between. The problem is all the records populated by the select statement are not inserted in to temp table. some records are not inserted.
Also, we had some other observation. It only happens in its 2nd execution and not its first run. Hope there might be some cache problem
Even, we also did not believe that. We are wondering. In TOAD, we tested however at times it happens. In application jar file, after "insert in to temp select * from xxx" we take the i. record count of temp table and ii. record count of "select * from xxx" separately but both doesn't match. Match only at 1st time.
I have created a type of type OBJECT:
CREATE OR REPLACE
TYPE MF_RECORD_TYPE IS OBJECT
(name VARCHAR2(6),
.
.
.
CREATE OR REPLACE
TYPE MF_TABLE_TYPE IS TABLE OF mf_record_type;
Then in my stored procedure:
v_mf_record MF_TABLE_TYPE := MF_TABLE_TYPE();
.
.
OPEN mf_detail;
FETCH mf_detail BULK COLLECT INTO v_mf_record;
CLOSE mf_detail;
[code]....
I am getting the error: PLS-00386: type mismatch found at 'V_MF_RECORD' between FETCH cursor and INTO variables.
The thing is, that type I defined is like 90 columns, and I'm trying to avoid having to list all those columns individually in the FETCH or when I retrieve the data.
I had two installations of Oracle on my server (10.2.0.4 and 11.2.0.1) under different linux users. The Databases used different listeners on different ports.
I upgraded my Oracle 11g to 11.2.0.3 successfully two weeks ago. However today I just checked that I couldnt reload my Oracle 10g Listener. On further analysis (lsnrctl status) I discovered that my 10g listener's version was "TNSLSNR for Linux: Version 11.2.0.3.0" . My Start Date from lsnrctl gives me the date when my Oracle 11g was upgraded.
Now I have tried to reload my 11g listener which works normally. I cannot reload my 10g listener (TNS-01190: The user is not authorized to execute the requested listener command). When i run ps command there is no process on my server for my 10g listener. I can only see my 11g listener process after running ps command. However everybody can ping my databases on Oracle 10g but i cannot identify or kill my listener process even on server level.

The cost of this query is 1677 and it is taking around 60 msec to complete. When I run this query for around 2000 employees in a loop it is taking around 3 minutes to complete.
The main bottleneck of this query is in the with clause where I am processing the entire history instead of stopping after first change.
ORA-31180: DOM Type mismatch in invalid PL/SQL DOM handle
I am getting this error while debugging one of the package in PL/SQL developer or in TOAD. Is there any setting which we need to perform at the database level to debug the packages which have the code related to XML DOM. I am asking as the same code works exactly fine at one of the test database and it gives the above error on the other database.
in my catalog database I see in Rc_datafile mismatch sizes - column bytes shows data different from the real sizes of files .
Does this view updated after copy of database into catalog ?
