SQL & PL/SQL :: Find Maximum Value Within A Group For Corresponding Types

Oct 25, 2010

Test data for the problem is as follows.

SQL> select * from v$version;

BANNER
----------------------------------------------------------------
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for 64-bit Windows: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production

SQL> with t
2 as
3 (
4 select 1 id, 12 compid, 1 rel_type, null enddt from dual union all
5 select 1, 13, 1, to_date('31.12.1993','dd.mm.yyyy') from dual union all
6 select 1, 14, 1, to_date('12.06.1996','dd.mm.yyyy') from dual union all
7 select 1, 15, 1, to_date('23.04.2003','dd.mm.yyyy') from dual union all
[code].......

I want to find the the latest compid for individual types 1 and 2 only within a list of ids. Latest compid is defined as the compid associated with the latest end date (null is treated as the latest end date).

So in the above example for rel_type = 1, compid : 12 is latest, for rel_type : 2, compid : 6 is latest.

Datatype for the tables are :

Id : Number
compid : Number
Rel_Type : Number
enddt : Date

SQL & PL/SQL :: Using Analytic Function To Determine Maximum Concurrent Calls?

Apr 27, 2010

I have a requirement to calculate the maximum number of concurrent calls from the following data:

Create_date connect_date_time disconnect_date_time duration ...
12/01/10 13:20:26 1263253551 1263254153 602
...

I have attempted to use the analytic function to keep a running total of the count of active calls based on the connect and disconnect times given for each record row.

e.g.

SELECT
count(*) calls,
avg(duration)/60 average_duration_mins,
max(duration)/60 max_duration_mins,
sum(duration)/60 total_mins,
(SUM(DURATION)/60)*0.04 total_cost_4c_per_min

Semantic Technologies :: Maximum Node ID Larger Than Java Maximum Integer Value

Mar 7, 2013

I'm currently doing migration from Oracle 10gR2 RDF to Oracle 11gR2 Semantic Technology.I followed the steps on the documentation and successfully created the network using the following:

-----
EXECUTE SEM_APIS.CREATE_SEM_NETWORK('rdf_tblspace');
CREATE TABLE rdf_network_trace (id NUMBER, triple SDO_RDF_TRIPLE_S);
--Created SEQUENCE andTRIGGER FOR rdf_network_trace id
[code]....

when I looked at my Node Ids, they were like +635762253807433724+, +6118969225776891730+. The problem is, I am not the one who is assigning Node Ids, They were automatically generated when inserting TRIPLE data to the rdf table.

Did I miss something when I created my network?

SQL & PL/SQL :: How To Write Function To Find Unique Value In Table

Aug 5, 2013

Create a function which will indicate if a given record in a table is unique or not. Unique means the data is occurring only once in the entire table.

Function should be in this signature

function IS_UNIQUE (tableName in varchar2,tableAttribute in varchar2)
return number
.....
begin
//logic to check if given data is unique
return 0; //return 0 if data is unique
else
return 1; //return 1 if data is duplicate
end;

Once I run this query

select attribute1 from table1 where IS_UNIQUE(table1,attribute1)=0

All records of attribute1 which are unique need to be fetched. Similarly, select attribute1 from table1 where IS_UNIQUE(table1,attribute1)=1 should return all records of attribute1 which are duplicates.

SQL & PL/SQL :: Function To Find Max Last Logout Date For Each Agent Daily

Jun 3, 2010

I have to create a function. I need to find the max last logout date for each agent daily. For example, if an agent logged in for the first time at 9:00 and he logged out at 12:00 and he logged in again in 14:00 and he logged out at 15:00 the time I need my report to show is 15:00. How can I do that?In order to make it easiest for you to understand I am sending you this query:

select
a.login as login2,
To_Char(max(s.endtime), 'dd/MM/yyyy, HH24:MI:SS') as lastLogout
from cti.agent a
inner join cti.agentsessionlog s
on s.agentid = a.agentid and To_Char(s.endtime) != '31-DEC-99 11.59.59.000000 PM'
group by a.login;

This query returns the agent's login and the agent's last logout time. It works fine if I enter a date between but I cannot do that. If a use this query as it is and I try to export a report for 31/5 it shows as lastlogout the logout for 01/06 or 2/06. Is there a function I can use? I have a deadline.

Function To Find Business Days Between Two Dates - Query Tuning

Mar 17, 2011

I have a query that uses a function to find the business days between two dates.It sums the total number of days between two dates per employee to find the total days for the past 30, 90, or 365 days.

The problem is that the query takes 21 second to return the last 30 days.Over 70 second to return the last 90 days and over 140 second to return the last 365 days.Do you know how I could tune the query to return faster? Below is the query for the last 30 days:

select dwt_emp_id, SUM((SELECT GET_BDAYS(DWT_DATE,DWT_CREATE_DATE) FROM DUAL))
from dwt_dvt_work_time where dwt_create_date > sysdate - 30
and dwt_hours > 4 and dwt_usr_uid_created_by <> -1 group by dwt_emp_id order by dwt_emp_id

Here's the function:
CREATE FUNCTION get_bdays (d1 IN DATE, d2 IN DATE)
RETURN NUMBER
IS total_days NUMBER(11,2);
holiday_days NUMBER(11,2);
[code]....

SQL & PL/SQL :: How To Remove Duplicates From Collection

Mar 24, 2011

remove duplicates from my collection(table type).Or an alternate solution for my issue is get clean data into my collection which i am not able to get to either.

Object creation

create table testingtype_table(ordernumber number,org_id number , company_name varchar2(10))
insert into testingtype_table values (1124,2424,'cbaaa');
insert into testingtype_table values (1124,2424,'cbaaa');

create or replace type testingtype_obj as object (ordernumber number,org_id number , company_name varchar2(10));
create or replace type testingtype_tab as table of testingtype_obj;

Code Block
declare
l_testingtype_tab testingtype_tab := testingtype_tab();
begin
select distinct testingtype_obj(ordernumber
,org_id
,company_name)
bulk collect into l_testingtype_tab
from testingtype_table;
end;

If only i can get a way to bulk collect only distinct values into the table type that will just do great but when i try the above (with distinct highlighted in red) it throws an error

ORA-22950: cannot ORDER objects without MAP or ORDER method

SQL & PL/SQL :: Populating Ref Cursor From Collection?

Aug 17, 2011

I have an existing Procedure that uses a ref cursor as a parameter. The procedure currently simply selects data into the ref cursor using an OPEN FOR and then exits.

I have a need to extend the processing of the procedure. This will mean retrieving extra columns in the select and also removing some of the retrieved records.

I have the constraint that the definition of the REF CURSOR (which is based on a record type as follows) cannot be modified.

TYPE t_charge
IS
RECORD (
id number,
date_from invoice_detail.from_date%TYPE,
date_to invoice_detail.to_date%TYPE,
description invoice_detail.desc_text%TYPE,
amount invoice_detail.amount%TYPE
);
TYPE t_charge_cursor IS REF CURSOR RETURN t_charge;

The procedure does this

PROCEDURE get_bill_lines (
p_bill_id IN NUMBER,
bill_lines_list OUT t_charge_cursor )
IS
OPEN bill_lines_list FOR
SELECT id, from_date, to_date, desc_text, amount
from invoice_table
where id = p_bill_id;

I am thinking instead of selecting directly into the bill_lines_list parameter I will use a local REF CURSOR to select into a COLLECTION. I can then do some work on the collection, similar to below:

PROCEDURE get_bill_lines (
p_bill_id IN NUMBER,
bill_lines_list OUT t_charge_cursor )
TYPE t_local_charge
IS
RECORD (

[code].....

This all works fine, but the question is, how do I then put the collection into the bill_lines_list REF CURSOR where the '*** HERE ***' comment is so I can send the existing REF CURSOR structure back? (Remember I cannot change any definition that is referenced externally)

SQL & PL/SQL :: Searching Collection For A Specific Value?

Oct 18, 2011

I need to check if a small collection contains a specific value. I know I can use the .exist method to let me know if the nth element exists. But is there a similar syntax for checking if an actual value exists?

So the below collection has 6 values (300,301,310,320,400,410) after the cursor values are fetched. I want to use something similar to the below exists syntax in order to search the collection for a value (rather than position) within an IF statement.

The below code shows the kind of thing I want to do. Currently, unless my test value (310) is in the range 1 to 6 the test will always return FALSE. But is there a similar syntax for testing against the value?

The example I have given is a simplification of what I need. In reality there will be more than one test value... returned by another cursor.

DECLARE
CURSOR c_type_id_usg
IS

[Code]....

-- get the list of sms type id usg values
OPEN c_type_id_usg;
FETCH c_type_id_usg bulk collect into l_type_ids;
CLOSE c_type_id_usg;

-- the above returns value 300,301,310,320,400,410

IF l_type_ids.exists(310)
then
dbms_output.put_line('I have found an entry ');
else
dbms_output.put_line('I have NOT found an entry ' );
end if;
END;
