SQL & PL/SQL :: How To Increment Count When GROUP By Is Used
Feb 17, 2010
SNO column should be incremented depending upon the total records to be fetched.if i get 4 records then sno numbers should be 1,2,3,4.i dont want to put rownum also in the GROUP BY clause.how to increment the serial number?
SELECT JC.A,
ROWNUM SNO, --serial number
JC.B,
SUM(CHR.AMOUNT),
SUM(CHR.FINALAMOUNT),
JC.C,
JC.D,
C.E,
JC.F,
JC.G
FROM CHARGES CHR
WHERE JC.B = '12111'
AND JC.STATUS = 'INVOICED'
GROUP BY JC.A, JC.B, JC.C, JC.D, JC.E, JC.F, JC.G;
I'm trying to group sets of data based on time separations between records and then count how many records are in each group.
In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5
SELECT AREA_ID AS "AREA ID", LOC_ID AS "LOCATION ID", TEST_DATE AS "DATE", TEST_TIME AS "TIME" FROM MON_TEST_MASTER WHERE AREA_ID =89 AND LOC_ID ='3015' AND TEST_DATE ='10/19/1994';
[code]....
Group 1 = 8:00:22 to 8:41:22
Group 2 = 11:35:47 to 11:35:47
Group 3 = 15:13:46 to 15:13:46
Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.
I'm using this code, and it performs fine, but I'm wondering if there is a more elegant way to do it--maybe with "ROLLBACK". Basically (as you can see) I need to get a normal count for each group but also for each group take a percentage of the total count (so all groups pct adds up to 100 (oh yeah, don't test for zero below, but just a test... )
select c.Event, c.code, count(1) as calls, total.total_count, count(1) / total.total_count * 100 as pct_of_total from table1 c
[Code]....
[Edit MC: add code tags, do it yourself next time]
But I cannot get the count I have to do a separate Query to get the count here it is How can I put the two together to get my count information and Report information together in one Report???
Select Count(pm.description), mv.R1_State FROM windsoradm.member_mv mv
I am trying to count the number of IDs dropped and enrolled in each unit for each of the 4 terms between their perspective dates. There are 4 Terms and an ID can participate in a unit in any of these terms:
I am trying to count how many IDs enrolled in a unit between those dates and how many doped before the end dateThe ENROL_DATE for each ID in a unit has to be between the given Term Dates to count. Unit KIS has 1 ENROL and one DROP in TERM 1 UNIT POL occurs in TERM 2 and 4 and both DROPUNIT LIN and 1 ENROL and 1 DROP in 2 different TERMS My problem is how do i specify count ENROL and count drop between the Term dates and then group by TERM and UNIT.
I want to list every patients number and name, and the number of treatments given by a certain doctor (e.g doctor name = 'smith'). the problem i am having is that if i specify the doctor is WHERE clause it only gives me the doctors who are under 'smith' but i want all even if 'smith' has given them 0 treatments. below is code that i have so far to view all patients with corresponding data.
select pa.patno, pa.lname, tr.treatno from patient pa full join treatment tr on tr.patno=pa.patno;
and i want display the product that sells best in every store. I try to group by multiple columns counting how many times each product was sold in every store, but don't know how to select the one which was best sold (maximal number of times)
We have a table with timestamp column and having millions of records.We want to create a materialized view or query, which can give count based
-on some group by columns from table and -group by on condition (if count > 1000) and -group by on condition (if timestamp range for that group is > 1hr)
Department EmpName ____________________________________ Sales empname1 Sales empname2 Marketing empname3 Development empname4
Now I want to count the number of employees in every department. I want the output to be
Department Total ______________________ Sales 2 Marketing 1 Development 1
I am retrieving names of the department through a subquery
The query I am trying to execute is:
SELECT Department, Employee FROM ( SELECT ...query from other table) AS Department, count( A.EmpName) AS Employee FROM Employer A, EmployeeInfo B WHERE (A.EmpID = B.EmpID AND A.EmpCategory like 'Category2') GROUP BY Department
I know that you cannot group by using aliases and hence a little work around, but still the query isn't working.
I am trying to create a table that will increment my ID by one using the following commands:
/*Creates the log needed to increment ID*/ create sequence seq_log; CREATE TABLE MESSAGE_LOG_TABLE ( IDNUMBER(10)NOT NULLPRIMARY KEY,
[code]...
When I run the above my create sequence completes successfully but I get a ORA-00955: name is already used by an existing object error message on the create table. I have dropped all tables and sequences before running my command but I still get the same error message.
After it bombs out it appears that SQL+ want's more information for it begins to give me line numbers as if it is looking for a ";" to end the above command. I have to exit SQL+ and log back in to continue working.
Srl no - Srl no w.r. to the date of transaction.i.e will be incremented for every day and should again reset for the next day-Length -4 Purpose code -Purpose code of the transaction.
I have a table abc with name and phone_number columns in it,and this table contains 100 records. Now I want to add a column say ID as primary key for this and it should be auto incremented and should have primary key for the first 100 records as well.
I have a problem I am making a rooster I want to increment dates. User will put input the first date then it have to incremented by user click i used Key_Next_item on Date Field.
if System.cursor_record >1 then Doctor_Rooster_Details.Week_Date =:Doctor_Rooster_Details.Week_Date +1 Its gives me error on KeyNext_ITem of ORA
I have fields
Week_Date Day St_Time EndTime Available 01/02/2011 Friday 10:00 12:15 Y
I want to increment Week_date when user click on next record it will incremented. ST_Time, End_Time and available user will input that.
i need to be increasing the sequence no by 1 for every calender date.For example lets say if i receive 5 dumps of data for 24/09/2013 it should be as below. For next day the 25th the sequence no should again begin with 1.
I have three tables. One for projects, one for volunteers, and a bridge entity for the many to many relationship between the Project and Volunteer.
In Project table, I have a field called, Volunteers_currently_signed_up, which means the number of volunteers currently signed up to participate in a project.
When I add an entry to my bridge entity which is composed of Volunteer_ID and Project_ID, I want the Volunteers_currently_signed_up to increment by 1, where the Project_ID in the bridge entity corresponds to that in Project.
I have very very little PL/SQL, and this is my amateur attempt so far:
CREATE OR REPLACE trigger "BI_Volunteers_currently_signed_up" BEFORE INSERT OR UPDATE ON Volunteers_in_project for each row WHERE Volunteers_in_project.Project_ID=Project.Project_ID; begin Project.Volunteers_currently_signed_up += 1; end; /
CREATE TABLE test (id NUMBER PRIMARY KEY, name VARCHAR2(30));
Step2
CREATE SEQUENCE test_sequence START WITH 1 INCREMENT BY 1;
Method1 Follow Step1 and Step2 and create a Trigger as below :
CREATE OR REPLACE TRIGGER test_trigger BEFORE INSERT ON test REFERENCING NEW AS NEW FOR EACH ROW BEGIN SELECT test_sequence.nextval INTO :NEW.ID FROM dual; END; /
Method 2 Follow Step1 and Step2 and directly have an insert statement as below:
INSERT INTO test (id, name) VALUES (test_sequence.nextval , 'Jon343');
Method 1, the Trigger is not getting created, however by following Method 2, I am able to generate auto-increment number.
I want to increment a counter in a loop based on a condition.
Here is how my xml looks like
<result> <resultset id=1> <value>
[Code]....
I need to look at each and every resultset and check if the value is >400 and if it is then display some text. Something like this
<outputvalue> Yes, there is a value greater than 400 </outputvalue>
In my XSL, I declared a variable called count with value 0. I created a for-loop which goes through these results. Then inside the loop there is a condition to cehck if the value is > 400. If the value is >400, then the counter is incremented.
I am switching database from access to oracle 11g. I have create all the required tables, but I am stuck at one point. The previous person who created access database had auto increment with SG0101, SG0102,........ In oracle I know we can auto increment primary keys but only with the numbers not with characters.
So I have customerid which is a primary key and it automatically increments the number, but I have one more column with memberid where I am inserting all the ids that start with SG0101 bla bla.....
I already have 800 member ID's that start with SG, but that value doesnt automatically increment because I dont have any sequence or trigger to do that.
So how do I create a sequence and trigger that will automatically start value with SG and keeps auto incrementing?
I have already done auto increment by making sequence and trigger. but now the problem is when i am trying to retrieve data from that table it returns all data perfectly but the primary key that is my auto increment value shows blank.I am facing this problem with join query, there 4 table left joined in my query. But when I remove join from my query then it shows that value.
But i need that value in my join query.So, what is the problem and what can I do?And other thing is when I apply this query in Oracle SQL Developer, it works perfect.
My Query: return $this->db->query("select * from TBL_EMPLOYEE_BASIC left join TBL_EMPLOYEE_DETAILS on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_DETAILS.EMPL_ID left join TBL_EMPLOYEE_EDUCATION on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_EDUCATION.EMPL_ID left join TBL_EMPLOYEE_EXPERIENCE on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_EXPERIENCE.EMPL_ID where
I'm trying to create a sequence for a primary key to simply auto-increment by the default of 1. I have a sql script written to generate mt tables, and I'm not sure how to modify the script to include the sequence. I also just want the sequence for a specific column, ie, PK, not the PK in all tables.
Here's a snippet from my script:
create table image ( image_id int NOT NULL, source_id int NOT NULL, CONSTRAINT image_id_pk PRIMARY KEY (image_id), CONSTRAINT fk_source_id FOREIGN KEY (source_id) REFERENCES source(source_id) );
Would I add the create sequence statement right after the create table, and if so, how do I apply the sequence to only 1 table and a single column?
I read that rownum is applied after the selection is made and before "order by". So, in order to get the sum of salaries for all employees in all departments with a row number starting from 1, i wrote :
select ROWNUM,department_id,sum(salary) from employees group by department_id
If i remove rownum, it gives the correct output. Why can't rownum be used here ?
How to check for the increment of a space of the tablespace based on the particular table. (i.e.) Say a scenario, if am trying to load the data for a particular table, for first I loaded some 10000 records and then again loading 50000 records ,so based on the icrement of the reocrds the tablespace size also increases gradually . so for this scenario how to monitor the increment of the space.
difference between count(1) and count(*). As i know count(*) will give number of rows irrespective of null and count(1) will not count the null.My Oracle version is 10 g.
