I am fetching records from many voluminous tables having multiple joins based on filter criteria filled from frond end application. As per the selected criteria, I want to have a pre-check if query would return more than 1000 rows then I have to show user a message saying that he should refine the search. Is there any performant way to query db and dynamically find record count and stops executions if it is going return more than the specified no of rows.
I have a database in 10g in entreprise edition but i don't understand why the dba_feature_usage_statistics return no rows ? On some database when i look at dba_ feature_usage_statistics Protection Mode - Maximum Performance is used and active why?
I have a history table which has a new record written to it for every time static data is updated. What I want to do is return any record that has been changed on a daily basis returning both the new record and the previous record so you can see the 2 records one below the other and compare.I have written the below but it returns all records per account:
SELECT H.Timestamp,H.AccountNo FROM History H where exists (select H2.AccountNo,count(*) from History H2 where H2.AccountNo = H.AccountNo group by H2.AccountNo having count(*) > 1 ) Where H.Timestamp > '20111101' order by H.AccountNo,H.Timestamp
create table emp1 (empno number,deptname varchar2(30),deptno number,sal number); insert into emp1 values (1,'Bank',10,1000); insert into emp1 values (1,'Finance',20,400); insert into emp1 values (2,'Finance',20,4000); insert into emp1 values (3,'Account',30,3000); commit; select * from emp1;
actual output :
empno deptname deptno sal 1 Bank 10 1000 1 Finane 20 400 2 Finane 20 4000 3 Account 30 3000
Expected output :
empno deptname deptno sal 1 Bank 10 1000 2 Finane 20 4000 3 Account 30 3000
I am looking a output like above one. if any empno belongs to deptname Bank then give priority to that values else go to other dept like Finance but empno 1 should return only one row.i.e Bank dept only.
I have to return only one row based on dept values for one empno. how to do in sql or plsql?
I want my query to return the rows of the table where a column contains a specific values first in a certain order, and then return the rest of the rows alphabetized.
For Example:
Country ALBANIA ARGENTINA AUSTRALIA .... CANADA .... USA ....
Now i want USA and CANADA on top in that order and then other in alphabetized order.
I used select distinct(work_order) to come up with the three different possible scenarios the problem is that i need all this information on a single row
this is a conversion for distance. when i get this to work properly, it will generate reports on thousands of work orders with their converted distance markers.
is there a way to return the next 7 dates just using a query... for example, I need a query that returns:
select (I don't know that put here) from dual
Date 2012-10-05 2012-10-06 2012-10-07 2012-10-08 2012-10-09 2012-10-10 2012-10-11
If possible, I would like to know if there's a way to pass a date and based on it, the query returns the next 7 dates based on the passed date... for example:
select (I don't know that put here) from dual where date > '2012-10-15'
Date 2012-10-16 2012-10-17 2012-10-18 2012-10-19 2012-10-20 2012-10-21 2012-10-22
I've stucked with a query. I have a table that i store the IDs of logically equal records.
For example; A = B B = C X = Y Z = Y
My query must return all equivalent records. If you call the query with parameter 'A', the result set must contain B and C. And if you call the query with parameter 'Y', the result set will contain X AND Z. I have thought that i can write the query wity using start with connect by statement. But the query does not work as i expected. Here is my code and sample data:
create table temptable (ID1 number,ID2 number);/
insert into temptable values(11,12);/ insert into temptable values(12,13);/ insert into temptable values(13,14);/ insert into temptable values(13,15);/
SELECT distinct ID1 from ( SELECT * FROM temptable START WITH ID1 = 13 OR ID2 = 13 CONNECT BY NOCYCLE ( (PRIOR ID1 = ID1) OR (PRIOR ID1 = ID2) OR (PRIOR ID2 = ID1) OR (PRIOR ID2 = ID2)) ) WHERE ID1 <> 13 union [code]....
When i call the query with parameter 13, i'm expecting to get 11,12,14,15. But it returns only 12,14 and 15.
select order_number, (select decode(hcp.contact_point_purpose,'ABC',hcp.email_address,'CDE',hcp.email_address,null) from hz_contact_points, hz_parties hz WHERE hz.party_id=hcp.owner_table_id) Email FROM oe_order_headers_all h WHERE h.order_number='102' .................... ..............
Actually the problem i am facing is the inner select query is returning multiple row , so my main query is erroring out, i need to capture the multiple row.
In the above example the inner decode statement returning two mail address, I need to capture that, but while executing the whole query it is erroring out as saying single query returns multiple values. capture multiple values
I am Having below query which is having total 664 records and for WHERE Clause (accountno ='13987135') it is having 3 records but when i am taking count it is returning 3 at first time and again returning 4 every time from then onwords.
I am new to SQL and I am just wondering if there is a solution to a problem I am having.I am using the piece of code below.Essentially what I am doing is selecting a field from a table and ordering that field in descending order. Using the Row_Number feature I then specify which Row I want to return.
Every day the row I will want is the Count of field1 for that day divided by 100 minus 1. This returns a single value of field1 and a single value of R.
I perform this operation every day. The only fields I change every day are the dates and the value of R. I use a seperate piece of SQL code to calculate R each day.
My problem is I have to often populate historical tables with this data. I can only run the code once for each day and for each value of R. Is there anyway I can alter this code such that it can return multiple values of field1 over several dates?The only way I can think of is to repeat the code multiple times using UNION but I am hoping there is a more efficient way.
SELECT * FROM (SELECT Field1, ROW_NUMBER() OVER (ORDER BY field1 desc ) R FROM table WHERE date >= TO_DATE ('20110215', 'YYYYMMDD') AND date < TO_DATE ('20110216', 'YYYYMMDD') ) WHERE R = 1227 --Note: 1227 = (count(field1)/100)-1
I have this query that returns results that contain duplicates(somewhat). I only want either the FIRST or LAST (either one is fine). Here is the query:
select unique PLLA.attribute4, PLA.item_description from po_lines_all PLA, po_line_locations_all PLLA where PLLA.po_line_id = PLA.po_line_id and PLLA.attribute4 is not null
So my output is something like this:
RCE12 This is an item for AUL1 RCE13 This is an item for PWEILL RCE14 This is an item for AUL1
I just want either the RCE12 or RCE14 record and not both since they both have the same description.
Having following table: UserID REC_TYP REC_CD 12345 'OFFR' 12 23456 'MSG' 13
I'd like to construct the query which in this particular case would return the REC_CD as 'Record_ID' for REC_TYP='OFFR' where USERID=? (always fetched by the application) and if such USER_ID doesn't exists (for the particular REC_TYP of course) to return string or any other value. e.g. The result for this query in case of user_id 23456 = would be "doesn't exist" or sth for instance 'FALSE' and for 123456 it would be '12'
I have a table with multiple rows for the KEY attribute(its not a primary key) and a Rank for each row.
I want a query which fetches one row per KEY attribute.The row with lesser Rank should be considered. But in-case if the value is null for any column the value for next Rank should be considered.
WITH TMP_TBL AS ( SELECT * FROM ( SELECT 'A' DUN,'1' RNK,'A21' col1,NULL col2,'A41' col3,NULL col4 FROM dual UNION ALL SELECT 'A','2','A122','A23',NULL,NULL FROM dual UNION ALL SELECT 'A','3','A32','A33',NULL,'A35' FROM dual [code].......
DUN is the KEY attribute . RNK is the Rank for each Row. COL1... COL4 are data attributes
I want this to be done with SQL only. So I tried various ways but none were successful.Finally I created a Multi Row function row_nvl and it worked.
SELECT DUN, row_nvl(rownvl_param_type(RNK,col1)), row_nvl(rownvl_param_type(RNK,col2)), row_nvl(rownvl_param_type(RNK,col3)), row_nvl(rownvl_param_type(RNK,col4)) FROM TMP_TBL GROUP BY DUN
But I don't think my manager will allow me to deploy a Multi Row function .
I have a need to query a real time production database to return a set of results that spans a three day period. When the three days are consecutive it's easy but sometimes there is a 1 or two day gap between the days. For example I'm querying results from a group of people that work between Tuesday and Saturday. On a Wednesday I need t produce a set of results that spans Tuesday of the current week, and Saturday and Friday of the previous week; on Thursday I need to produce a set of results that that spans Wednesday and Tuesday of the current week and Saturday of the previous week.I'm using SQL Developer to execute the code.
