If a particular department has 10 employees it should have data upto emp_name_10,if department has only 5 employess it should data upto emp_name_5 and so on.I came up with below approach, in this approach I need to create new table to store the data in row wise.
In my actual requirement 4 tables needs to be joined and 2 of the tables are very large.Is there any other approach without creating a new table, something within pl/sql.
drop table emp_dept; create table emp_dept(deptno number,dept_name varchar2(100),emp_name varchar2(100),hire_date date,seq_cnt number,total_cnt number); insert into emp_dept
Web page that retrives data from SQL database and display it to the user in well formatted manner. Data retrieved depend upon criterias selected by the user. But sometimes data retrieved is very large. I want to display records to the user page wise, i.e. 100 records on first page and next 100 records displayed when user clicks next button. This means only 100 records should be retrieved when user first select search criteria, next 100 records retrived when he clicks next button and so on, as to reduce data transferred from server to client. how to achieve this by using single sql query as soon as possible.
how to tune qurey for coulumn wise data saved.because we have to join same table n number of times.for reference go through the following scnarios.
Suppose one table T1 is there and it has two column KEY and VALUE.if we are writing qurey for retriving desire result in row manner we have to join samae table no of times.
KEY Value agreesWith true id 1 assessment False basisForDateOfProgression 1 bestOverallResponse 2 bestOverallUnknownComments data is ok
Qurey:
select * from ( select t.agreesWith from t1 t )a
[Code]...
In this manner we can join upto bestOverallUnknownComments .so which method we follow to reduce the execution time and performance should be good.
I have a requirement to list the data month wise dynamically where month data is also in the same table, hopefully the below posts should bring more clarity to my requirements.
I have a table name as angdata77 having attributes like asigno..i want to retrieve data from angdata77 by using both group by & order by clauses.. for total count..am using the query as
select asigno,count(*) from angdata77 group by asigno order by asigno;
Is there any other query for retrieving the data from angdata77
Name Null Type --------------------------- -------- ------------- RPTNO NOT NULL NUMBER RPTDATE NOT NULL DATE RPTD_BY NOT NULL VARCHAR2(25) PRODUCT_ID NOT NULL NUMBER
describe rptbody
Name Null Type ------------- -------- ------------- RPTNO NOT NULL NUMBER LINENO NOT NULL NUMBER COMMENTS VARCHAR2(240) UPD_DATE DATE
The fact is that we store some header in RPTHEAD and store real data in RPTBODY, the question is that if I use below SQL to query all data for a 'PRODUCT_ID'.
SELECT t0.LINENO, t0.COMMENTS, t0.RPTNO, t0.UPD_DATE FROM RPTBODY t0 , RPTHEAD rpthead WHERE ( t0.RPTNO = rpthead.RPTNO AND t0.UPD_DATE>=to_date('1970/01/01 00:00:00','YYYY/MM/DD hh24:mi:ss') AND rpthead.PRODUCT_ID IN ('4647') )
I do not want to have 'ORDER by' clause since data set is too large, the sorting takes long time, is there any way to get the result rows in the order sorted by RPTNO? We have the index for RPTNO on RPTBODY.
I have two block....both are the control block.. in first block i select the date and in second block the data of that date is populated.but the data is populated using cursor in when-button-pressed trigger of that first block button.in cursor the data is selected and placed in field of detail block using into clause.... each field and one item of detail block is srno which is create in post-query of detail block using :sysyem.trigger_record.
Now i want after populated the detail block the data is sorted desc one of the field of the detail block..Can this possible using set_block_property() of block although the block is control block if yes where i should do this?
I have a real problem with form, specifically one of its data blocks. In the order by property of the block i specify it to sort on a branch in ascending order(i tried descending as well) but for some reason the form ignores that and sorts it on the ROWNUM. I even removed the where clause, the order by clause and changed the query data source type to FROM clause and changed the data source name to pre-query. I then created the query string in the block's pre-query trigger and set query_data_source_name property to that query string and still the data in the block is not being sorted on the branch number but instead on the ROWNUM.
I have data block that has hundreds of records. On a screen I display 20 records at a time. On that same screen I have "find badge" function where user types badge/employee id and presses a button to find the record in a data block. I have no problem finding the records in a list and pointing the curser to appropriate record. My question is (which is a user request) if the badge/employee id is found to make that record to be the first record in a list.
We are trying to import data into existing tables in a schema using data pump
However the foreign key tables are being imported first and then the master table data thus violating the constraints
Apparently it seems larger tables are being imported first regardless of referential integrity constraints thus causing constraint violation (contrary to my understanding)
Is it a normal behaviour during data pump import?
Is it possible that the keys being sequence generated are causing this?
As I understand import will commit after each table In that case can we defer commit at all at the expense of large undo, set constraints to deferrable and try the import?
In oracle query can i want find out how many day wise count for a year days (for example how may sundays, mondays, tuesdays, wednesdays ,thursdays,fridays,saturdays) in a given year (we can give the start day of the year and the end day of a year).
example ---------- jan sun-5 mon-4 tue-5 wed-5 thu-5 fri-4 sat-5 feb ------------do--------------------------------- like this for all 12 months at a single query.
select in1.empid,in1.atttime,out.atttime from (select empid ,atttime from attend where status=1 and to_char(atttime,'mmyyyy')='022012' order by empid,atttime desc) in1, (select empid,atttime from attend where status =0 and to_char(atttime,'mmyyyy')='022012' order by empid,atttime desc) out where in1.empid=out.empid and in1.empid='02256' order by in1.atttime,out.atttime
But this query do .one value relation with all column.means first february in time with all out time.
OS : Windows 2003 DB : 10.2.0.4 I am doing capture and replay first time.I want to take 2 captures at a time. 1st capture for 2 schemas and 2nd capture for other schemas.Is it possible?I have searched on internet but didn't get any clue about it..
I have a table with starting date and ending date.
I want to fetch monthwise days for given two dates
IE starting 25/12/2009 ending 25/03/2010
Result should like below.
Dec-09 7 Jan-10 31 Feb-10 28 Mar-10 25
I have tried this but it is not giving me the result which want..
select to_char(thedate,'mon-yy') mnth,count(to_char(thedate,'mon-yy')) days from (SELECT TRUNC(to_date('25/12/2009','dd/mm/yyyy'),'Y')+ROWNUM-1 THEDATE FROM ( SELECT 1 just_a_column FROM dual CONNECT BY LEVEL <= 366

how can i compute row wise multiplication for each unique value of id. I am trying to get the output as showing id and their respective results after multiplying the corresponding values.
CREATE TABLE mult_tbl( id NUMBER, val number ); insert all into mult_tbl values (1,2) into mult_tbl values (1,3)
Is there any way to capture the version wise objects (Packages) information from the oracle data base.
Ex : I have package P1 which was created on 01-NOV-2012 with version 1 . After 10 days same package has been updated version 2 with some enhancements.Like that the package will be updated according to the latest requirement.
Now I need to capture the total audit trail history of the package with version wise specific changes and when changes has been occurred hoe can I achieve this?
