Need optimized T-SQL query
Hello,
I have a requirement where a table has ItemId & AuthenticationString (default to replicate('0',8000)) and other table has ItemId & CodeNumber. If in second table there exists a CodeNumber for a ItemId then AuthenticationString should have it as 1
for that position of CodeNumber.
CREATE TABLE ItemId
(ItemId INT,AuthenticationString VARCHAR(8000))
CREATE TABLE CodeNumber
(ItemId INT,CodeNumber SMALLINT)
INSERT INTO ItemId
SELECT 1,REPLICATE('0',8000)
INSERT INTO CodeNumber
VALUES (1,1)
INSERT INTO CodeNumber
VALUES (1,3)
INSERT INTO CodeNumber
VALUES (1,7)
INSERT INTO CodeNumber
VALUES (1,8)
output for this example should be '10100011000000000............' in AuthenticationString field. I am doing now by while loop & STUFF function. I am using SQL Server 2005.
Thanks in Advance.
CREATE TABLE ItemId
(ItemId INT,AuthenticationString VARCHAR(8000))
CREATE TABLE CodeNumber
(ItemId INT,CodeNumber SMALLINT)
INSERT INTO ItemId
SELECT 1,REPLICATE('0',8000)

Optimizing an SQL Query using Oracle SQL Developer
Hi ,
Currently i am using Oracle SQL Developer as my Database IDE .
Is it possible to use Orqcles SQLDeveloper for the purpose of Optimizing an SQL Query ??
For example assume i am having a query as :
Select from Tranac_Master where CUST_STATAUS='Y' and JCC_REPORT='N'*
Could anybody please tell me how can i use Oracle SQL Developer to optimize this query or any other SQL queries ??
Please share your ideas , thanks in advance .1. Your query looks very simplistic as it is, so I fail to see how you can better optimise it (unless 'Tranac_Master' is a view, in which case I'd need to see the view details).
2. No tool can automagically optimise your SQL to any degree of practical use. Very minor adjustments may be possible automatically, but really it is a question of you knowing your data & database design accurately, and then you applying your expert knowledge to tune it. -
Need help with SQL Query with Inline View + Group by
Hello Gurus,
I would really appreciate your time and effort regarding this query. I have the following data set.
Reference_No---Check_Number---Check_Date--------Description-------------------------------Invoice_Number----------Invoice_Type---Paid_Amount-----Vendor_Number
1234567----------11223-------------- 7/5/2008----------paid for cleaning----------------------44345563------------------I-----------------*20.00*-------------19
1234567----------11223--------------7/5/2008-----------Adjustment for bad quality---------44345563------------------A-----------------10.00------------19
7654321----------11223--------------7/5/2008-----------Adjustment from last billing cycle-----23543556-------------------A--------------------50.00--------------19
4653456----------11223--------------7/5/2008-----------paid for cleaning------------------------35654765--------------------I---------------------30.00-------------19
Please Ignore '----', added it for clarity
I am trying to write a query to aggregate paid_amount based on Reference_No, Check_Number, Payment_Date, Invoice_Number, Invoice_Type, Vendor_Number and display description with Invoice_type 'I' when there are multiple records with the same Reference_No, Check_Number, Payment_Date, Invoice_Number, Invoice_Type, Vendor_Number. When there are no multiple records I want to display the respective Description.
The query should return the following data set
Reference_No---Check_Number---Check_Date--------Description-------------------------------Invoice_Number----------Invoice_Type---Paid_Amount-----Vendor_Number
1234567----------11223-------------- 7/5/2008----------paid for cleaning----------------------44345563------------------I-----------------*10.00*------------19
7654321----------11223--------------7/5/2008-----------Adjustment from last billing cycle-----23543556-------------------A--------------------50.00--------------19
4653456----------11223--------------7/5/2008-----------paid for cleaning------------------------35654765-------------------I---------------------30.00--------------19
The following is my query. I am kind of lost.
select B.Description, A.sequence_id,A.check_date, A.check_number, A.invoice_number, A.amount, A.vendor_number
from (
select sequence_id,check_date, check_number, invoice_number, sum(paid_amount) amount, vendor_number
from INVOICE
group by sequence_id,check_date, check_number, invoice_number, vendor_number
) A, INVOICE B
where A.sequence_id = B.sequence_id

Edited by: Dominic Carissimi on Oct 28, 2008 7:56 PMIf you want the list of values for command level parameter then you need to add another command like
select PropertyField from table
and delete the links between this command and the existing command.
Now go to field explorer and edit the command level parameter and make it as dynamic and add the property field from newly added command.
Hope this helps!

Hi all,
I have data in the following manner:
CASE_NUMBER HOURS FLAG
1000 10 0
1000 20 0
1000 30 1
1000 40 0
1000 50 1
Here I need to Calculate the total hours for a Case_number till i see the flag as 1.
Here the result must be 10+20+30 Hrs
Another Example
CASE_NUMBER HOURS FLAG
2000 10 1
2000 20 1
Here the result must be only 10.
I am struggling to write a SQL query for this.
Anyones help will be very much greatful
Thanks in Advance
Regards,
Sengathir SubbarayanLook up analytical functions.
something like sum(hours) OVER (PARTITION BY case_number ORDER BY something)
will give you the sum for all rows.
Then you probably want to "throw away" those rows after the flag maybe by summing the flag column too, and throw away all those where the flag is greater than 1 and where it is equal to 1 except for the first one.
I suspect you actually have some other column (other than the number of hours) that define your order - that's what you put in the ORDER BY.

Need help in SQL Query: Update a row in a table & insert the same row into another table
I want to update a row in a table say Table A and the updated row should be inserted into another table say Table B. I need to do it in a single SQL query and i don't want to do it in PL/SQL with triggers. And i tried with MERGE statement but its working with this scenario. (Note: I'm using Oracle Database 10g Enterprise Edition Release 10.2.0.1.0).
Thanks in Advance.Using Sven's code as an example, you could save the updated row in a sql plus variable. (also untested):
SQL> var v_id number
update tableA
set colB='ABC'
where colC='XYZ'
returning id into :v_id;
insert into table A_History (ID, colA, colB, ColC)
select id, ColA, ColB, ColC
from tableA
where id = :v_id; -
Help needed in framing SQL query.
Hi,
I have table having following schema:
PRODUCT_ID INT
DATE DATETIME
ITEMS_SOLD INT
This table contains data for a week (sunday to saturday). I want to write an SQL query to get (filter out) PRODUCT_ID of products which has same no. of ITEMS_SOLD for all 7 days. Also for given PRODUCT_ID I need to find the longest period of successive days where the no. of ITEMS_SOLD is same for all days in this period. Eg.(PRODUCT_ID 23 was sold as following along the week in no. of units sold: 4,6,6,6,6,7,4 .So the longest period is *4 days* from Monday to Thursday.) The first condition is special case of second condition where no. of days is 7.
Any help to get the SQL query will be appreciated.
Thanks,
Akshay.PRODUCT_ID DATE ITEMS_SOLD
1 10/10/2011 3
1 11/10/2011 3
1 12/10/2011 3
1 13/10/2011 3
1 16/10/2011 5
2 10/10/2011 4
2 11/10/2011 4
2 12/10/2011 4
2 13/10/2011 4
2 14/10/2011 4
2 15/10/2011 4
2 16/10/2011 4
Output:
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
1 3 4
2 4 7
Explanation of results:
The table to be queried contains data for 1 week: from 10/10/2011(Sunday) to 16/10/2011(Saturday). Now, product with PRODUCT_ID '1' was sold on dates 10,11,12,13,16. Out of these 5 days 3 units were sold on 4 successive days (from 10-13). So output should be like :
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
1 3 4
as longest period of successive days is 4 where same no. of units were sold i.e 3 units (other period is of 1 day on 16th ).
For PRODUCT_ID 2 we have only one period of 7 days where 4 units were sold each day. So we output :
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
2 4 7
Other case where same PRODUCT_ID have different units sold on each day should be ignored.
I hope that clarifies the problem more. Let me know in case I have missed out anything which should have been mentioned.

I am trying to build a query that sums up 12 columns depending on some accounting variables.
example:
SELECT gbmcu, gbco, gbfy,'',SUM(gban01 gban02 gban03 gban04 gban05+gban06+gban07+gban08+gban09+gban10+gban11+gban12) AS Oil_Volumes
FROM PRODDTA.F0902
WHERE GBCO = '00099'
AND GBFY = 5
AND GBLT = 'QU' AND GBOBJ = 5015 AND GBSUB = '105'
GROUP BY gbmcu, gbco, gbfy
The condition that changes is :AND GBLT = 'QU' AND GBOBJ = 5015 AND GBSUB = '105'
I need to do this for 17 different conditions - I need to make the query as optimized as possible.
I tried using a case statement but that takes forever (the table is over 4 million records to scan through).
Please let me know if anyone has any suggestions on how to create something to perform these calculations.
thanks,
PamI think I would tend to write that query as:
SELECT gbmcu, gbco, gbfy,
SUM(CASE WHEN gblt = 'QA' AND gbobj = 5015 AND gbsub = '105' THEN
gban01+gban02+gban03+gban04+gban05+gban06+gban07+gban08+gban09+gban10+gban11+gban12 END) Oil_Sales
SUM(CASE WHEN gblt = 'QU' AND gbobj = 5015 AND gbsub = '105' THEN
gban01+gban02+gban03+gban04+gban05+gban06+gban07+gban08+gban09+gban10+gban11+gban12 END) Oil_Volumes
FROM proddta.f0902
WHERE gbco = '00099' and
gbfy = 5 and
gblt IN ('QA', 'QU') and
gbpbj = 5015 and
gbsub = '105'
GROUP BY gbmcu, gbco, gbfySUM the CASE rather than CASE SUM. Also, as written, your query will look at all of the records in f0902 whether or not they meet one of the Case criteria, so I would put the required values in the WHERE clause as well. Your samples only show gblt changing, so you may need to make the gbpbj and gbsub predicates IN lists as well.
If the query runs in 1.5 hours calculating one value, I would expect it to be about the same calculating 17 values, since I would bet that most of the run time is accessing the table rather than doing the math. It would almost certainly be faster than running essentially the same query 17 times.
Indexes on some or all of the columns in the WHERE clause may help, depending on how selective the columns are. At a guess, I would suggest that gbco and gbfy would be good candidates.
Finally, are you sure that gbsub is a character field? The only example we have is a number.

Need help with sql query dates
Hi,

Edited by: user9327712 on Mar 11, 2010 8:14 AMI have a table where the ids are stored.
*"object name"* column values are actually another table columns stored as rows here. So in our example prop_num, city,Misc 1, Misc 1 desc, Misc 2, Misc 2
desc,Misc 3 , Misc 3 desc are all columns. These would not change any time
The column object_value has values stored for respective columns.
436, dallas , 90 , min amount , 700 , interest amount are all column values. So these can change.
id object_name object_value
10 prop_num 436
20 city dallas

Need a SCCM SQL Query Report for Installed Software with Packages and Applications.
I need a report that will show the number of installs of all of the workstations applications and packages over a given period of time.
This will let us know how effective our deployments are and how well the on-demand software is being adopted.
Any help?Your Install Source might be an option as most SCCM deployments will install from C:\Windows\ccmcache\xx [where xx is a random folder name]. Most software vendors will put an install source in the registry, but not all do, so it won't be completely accurate.
When software is installed manually, the install source path won't be C:\Windows\ccmcache\xx.

I have a table, say VEHICLE, which contains MODEL, CITY, SOLD NUMBERS.
The table may be like this
MODEL SOLD NUMBERS CITY

Toyota 900 New Jersy
Honda 1700 California
Ford 1500 Mexico
Ford 1600 Delhi
Toyota 800 Chennai
Mercedes 1000 New York
I need to build a query which will return me the model name and the number of items sold.
The output of the query should be having the number of Honda sold and number of Ford sold, irrespective of the city.
The rest of the models should be combined and their combined number of items sold should be displayed as single row.
The output structure may be
MODEL SOLD NUMBERS
Honda 2900
Ford 3100
OTHERS 2700 (combined toyota and mercedes)
Please help me out regarding this.Although you asked this question in a wrong forum , still I will answer this question
as I belong to the Pl/SQL forum too.
Try the following query :

Now the query page-
<sql:query var="empList" scope="session"> select <c:out value="${param.service}" /> from map_service where cityname = ? <sql:param value="${param.cityname}" /> </sql:query>
Now I need to generate output with the given below value in the next page-
<c:out value="${param.service}" />
This value show value as si, sc sr only where I need the database table value as per selection.
I am really confused that what I should write as <c:out value="${...
My database table has attributes as cityname, si, sc, sr. etc.
when some one select si from radio button the value of radio button is passed to sql query and the value which is selected on the table after query should be used in developing output result please help.Dear Friend Is it not possible for any of you to give me a clue that if I've to get the output of *?* from the query what I can write in syntax.
