SQL & PL/SQL :: Write Outer Query Which Will Bring Individual Records Which Don't Sum Up To Zero
May 9, 2011I have to write a sub query / build a logic for the below.
There are several accounts which should have a zero balance i.e sum of all the amoutns in that account should be zero. If they are non zero , i have to report which amounts make up non zero balance.
If i have amts as +20 , -20 , -30,-10 i.e the sum is -40 indicating a non zero amount. I need the entire details of the records which makes up non zero sum. So in above case details related to -30 aand -10.
I'm using a sum group clause on several fields at which sum is required to be checked ie. date , account , currency . query that will bring individual records that don't make the sum zero.
Is it possible to write a outer query which will bring individual records which don't sum up to zero.
Query To List Employee Number And Amount Of Days Sick
Apr 19, 2009I have been trying to construct a query in Oracle that allows me to do the following:
For example if I have the data below:
EmpNo DOB SickDays
Alex 445 15/06/1985 7
Tom 778 22/08/1981 4
James 992 07/10/1978 5
I need to write and a query to lists the employee number and the amount of days sick that they have had and also add a column that compares the number of sick days to the average number of suck days by ALL employees.
I can calculate the average sick days etc, but It wont see to allow me to find the difference between that and the amount of sick days that each person has had. I have tried this many ways and have not been able to come up with a solution.

Enterprise Manager :: Unable To Bring Up OEM When Using Different Pfile
Jun 5, 2010what is missing in this pfile that would cause enterprise manager not to appear ?
In the Oracle Database 10g: Administration Workshop II The chapter 8 excercise calls for the database to be started using the pfile init_sgalab.ora . The purpose of this I suppose is to simulate a memory error.
When I get to the part where I need to use OEM to fix the problem, OEM does not come up. The contents of init_sgalab.ora are :
--------------------------------------------
background_dump_dest='/u01/app/oracle/admin/orcl/bdump'
compatible='10.2.0.1.0'
control_files='/u01/app/oracle/oradata/orcl/control01.ctl','/u01/app/oracle/oradata/orcl/control02.ctl','/u01/app/oracle/oradata/orcl /control03.ctl'
core_dump_dest='/u01/app/oracle/admin/orcl/cdump'
db_block_size=8192
[code].......
I am not sure what is missing in this file to be able to bring up OEM.
Also, I looked at the logs and this is the only error message I found that might be relevant in
/u01/app/oracle/product/10.2.0/db_1/jhlinux.home.com_orcl/sysman/log/emoms.log

SQL & PL/SQL :: Query Using DBLink Returns More Rows Than Direct Query?
Apr 6, 2010I have a query that is pulling back more rows when I use the dblink than when I hit the linked database directly.
For example:
select
x,y,z
from
mytable@dblink
returns 788,324 rows
while
select
x,y,z
from
mytable
returns 712,102 rows
It's the exact same query, with the only difference being the dblink. It's not pulling the data into a cursor or array, it's a simple, straightforward query on a remote database.

Performance Tuning :: Force Subquery To Use Index?
Aug 5, 2010I have the following query:
Select
tag0.TAG_VALUE pid, tag1.TAG_VALUE, tag2.TAG_VALUE From TAGGER.TAGGABLE_RESOURCE r
, TAGGER.TAG tag0
, TAGGER.TAG tag1
, TAGGER.TAG tag2
where 1=1
[code]....
This runs in about 400ms. Now I replace this:
ANDtag0.TAG_TYPE in (4602, 5228)
ANDtag1.TAG_TYPE in (4612, 5225)
ANDtag2.TAG_TYPE in (4613, 5226)
with this:
ANDtag0.TAG_TYPE in (select COLUMN_VALUE from ( select * from table( TAGGER.GET_IDS_OF_SIMILAR_TAG_TYPES('Patient ID') ) x1 ))
ANDtag1.TAG_TYPE in (select COLUMN_VALUE from ( select * from table( TAGGER.GET_IDS_OF_SIMILAR_TAG_TYPES('Patients Sex') )x2 ))
ANDtag2.TAG_TYPE in (select COLUMN_VALUE from ( select * from table( TAGGER.GET_IDS_OF_SIMILAR_TAG_TYPES('Patients Birth Date') ) x3 ))
So instead of hard coding the IDs there is a function that looks them up. The function itself is reporting that it runs in 0ms. But when I run the new query:
Select
tag0.TAG_VALUE pid, tag1.TAG_VALUE, tag2.TAG_VALUE From TAGGER.TAGGABLE_RESOURCE r
, TAGGER.TAG tag0
, TAGGER.TAG tag1
, TAGGER.TAG tag2
where 1=1
[code]....
it takes around 6s to run. I have looked at the explain plans it it seems as though the function based approach is triggering a full table scan of 'TAG'.
I have tried it with query hints to use index, but it doesn't change the execution plan, or the query time.
The explain plan for the quick query is:
PLAN_TABLE_OUTPUT
---------------------------------------------------------------------------------------------------
Plan hash value: 1031492929
---------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
[code]....
And the slow one is:
PLAN_TABLE_OUTPUT
----------------------------------------------------------------------------------------------------
Plan hash value: 2741657371
----------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes |Te
----------------------------------------------------------------------------------------------------

Force View Number Data Type Precision?
Aug 18, 2011I am working on an application that pulls data from an Oracle view into Microsoft Excel (Oracle 11g, MS Excel 2003). It is an automated pivot table created through vba. The problem I'm having is that the decimal points from number columns are being truncated - they don't make it to the pivot table.
When I use the pivot table wizard and set the external data source using a SQL string (select * from view), the precision is not lost. When I create the pivot table automatically in vba, the precision is lost. The pivot table settings, regardless of how the data is brought in, shows the format of the number column as general. This tells me that Excel is trying to figure out what the data type is, and can't (not smart enough).
When looking at the description of the view, the data type is NUMBER (no precision). The table that it is pulling from has the precision set (NUMBER(11,3)). I have tried using the following, but it doesn't work:
select to_number(field_name, '99999999.999') field_name from view
Performance Tuning :: Force Optimizer To Consider All Join Permutations?
Oct 14, 2013I'm looking to see if there is a way (fully expecting it to be an underscore, or two...) to force the optimizer to keep churning until all permutations are exhausted.I'm aware that it, to paraphrase, cuts out when it's spent more time parsing than it would just running it based on it's estimates.
I've got some irritating problems with xml rewrite, xml indexes and access paths/cardinalities etc and I'm really needing the entire thing considered as a one off for debugging this. I've already cranked up the maximum permutations to the max but it's not enough, it shorts out after 5041 permutations (I'd set that to 80000 max).
I know you'd not want to do this in the real world but I cant get the damned thing to run the plan I want in a 10053 so I can see the values it has there. I know I can hint it, but I'm trying to ascertain why it's not even considering it in a "normal" parse.

PL/SQL :: Query - Rows In Columns
Jul 27, 2012I have following table -
CREATE TABLE group_device
( group_id NUMBER (8) NOT NULL
, member_id NUMBER (4) NOT NULL
, device_id NUMBER (10) NOT NULL
, install_date DATE NOT NULL
, remove_date DATE
);
[Code]...
Current output does looks like below
10 1 123 23-MAY-12 28-MAY-12
10 1 456 28-MAY-12 01-JUN-12
10 1 789 01-JUN-12
10 2 999 04-MAY-12 17-MAY-12
10 4 1123 22-JAN-12 27-JAN-12
10 4 1456 27-JAN-12 28-JAN-12
Device_id - Replaced_device_id - remove_date :: For group_id=10
e.g. for member_id = 1, device_id=123 got replaced by device_id=456 on 28-May-12
device_id=456 got replaced by device_id=789 on 01-Jun-12
So output should look like this
10 123 456 28-May-12 -- Replaced
10 456 789 01-Jun-12 -- Replaced
10 789 -- Active
Similarly there will be many groups, so it should list based on group_id
Client Tools :: Force Parameter Value To Change Filename For Every Execution Of Sql Script
Jan 24, 2012I wrote an sql script (spooler) which runs a select query and produces results into a file.
I want to have the filename with the year attached. Can i pass a parameter when i run the script from SQL*PLUS
@'B: Year Of FinancingPLSQLspoolersSpooler_File_Creation' 01/01/2010 2010;
the first parameter 01/01/2010 is passed to the select query and taht works fine.
Since the output file contains 2010 data, I want the spooled file to mention in its name the 2010, so User's can know the file contains 2010 data in it.
So i wrote the statement within the spooler script
SPOOL X:HARSOrganizationsFinancialDataFor&2.txt
&2 should take 2010 has its value and produce the file FinancialDataFor2010.txt
how to use Substitution variables to produce the Filename i want.

Application Express :: How To Force APEX To Fire Submit After Processes Before On-Demand
Jul 2, 2013We have an application that has "After Submit" and AJAX "On-Demand" processes. We need the "After Submit" to fire and complete first, set an application item (by referencing the next value in a sequence), and then fire the "On-Demand" processes. We have the sequence number set accordingly, with all of the "After Submit" processes given a lower (APEX) sequence number than the "On-Demand" processes; however, it seems the "After Submit" processes are still not firing and completing because only intermittently are the "On-Demand" processes able to access the application item's value--80% of the time this value is simply blank. Making matters more complicated is that the application item is derived from an Oracle sequence, so in my "On-Demand" processes, I cannot simply re-run some of the same logic used in one of the "After Submit" processes that sets the sequence--the sequence may only be set once, and only by this "After Submit" process; we have no choice in that regard. Is there any way possible in APEX to 100% force processes to fire AND complete, one after another, in the order in which they are listed by their (APEX) sequence? In other words, if we have this:
(APEX) Seq Name & Process Type
1 process A ("After Submit")
2 process B ("After Submit")--this sets application item :XYZ
3 process C ("On-Demand)--this uses application item :XYZ and MUST have this item value available to do any processing Can we instruct APEX to fire process A, complete it, fire process B, complete it, and only then, fire process C?
Converting Query Rows Into Columns?
Sep 14, 2008I have seen lots of examples of using PIVOT to return an sql query where the rows have been converted to columns. All the examples I can find require you to have two columns with multiple rows, and also require you to know the data which is in one of columns to make titles for the new columns.
I need something a little different...I have a query using UNION which goes something along the lines of...
SELECT [get data from one place]
UNION
SELECT [get data from another place]
UNION
SELECT [get data from another place]
this returns the following...
a_val
-----
100
200
300
query to return something like this...
a_val1 a_val2 a_val3
------ ------ ------
100 200 300
The names of the columns don't really matter. And I dont want to create a new table in the database just for the result.
