I get the following query result:
EmployeeName payelement payelementValue payelementOrder
------------ ---------- --------------- ---------------
emp1 PE1 122 2
emp1 PE2 122 1
emp2 PE1 122 2
emp2 PE2 122 1
emp3 PE1 122 2
emp3 PE2 122 1
Which results in a report that looks like:
Employee Name PE2 PE1
emp1 122 122
emp2 122 122
emp3 122 122
I have created a matrix in rdlc report and and put the column field with the ->'payelement ' and the value field with ->'payelementValue' and set the rows field with ->'employeeName ' the problem now is that I want to sort the 'payelement' upon the field named 'payelementOrder' which represents the order for paylements in their actual table while I actually get them sorted alphabetically by defualt i.e.(PE1 then PE2). Any help would be greatly appreciated.
I Solved by this...
Go to the .rdlc... Check the Row Groups(which we will find in the left-bottom) under of that we will find the grouped column name (which we are having in the tables) then right click on it-> Go to Group properties... -> Go to sorting-> on the sort by give the column name which you want to sort according to and Click Ok.
And You are Done....
When you created a matrix you got a Column group. In the group properties of the column group you can set order by specific field (payelementOrder in your case)

I want to have a new column showing how many orders that I have for the shipment.
How can I do that in obiee
Example Table:
Shipment
Order
Order Quantity
125
001
3
125
002
3
125
003
3
126
004
2
126
005
2
I can't have a new column with order quantity for each shipment
Add a sum for the "Shipment" attribute to the visualization and the tool does it automatically. Or create a measure using SUM("Order Quantity" by "Shipment") which you can then use to cross-calculate
Good evening,
I am trying to understand in which cases the sequence would be used, for the example below, since the rowids would not always give me a single row to manage the changes.
Why consider a sequence of additional fields?
I will be grateful if you could clarify the doubt, with some example.
Thank you so much,
Greetings.
CREATE MATERIALIZED VIEW LOG ON sales
WITH ROWID, SEQUENCE(amount_sold, time_id, prod_id)
INCLUDING NEW VALUES;
Now imagine that you want to create a materialized view that contains aggregates on this table. Because the materialized view log has been created with all referenced columns in the materialized view's defining query, the materialized view is fast refreshable. If DML is applied against the sales table, then the changes are reflected in the materialized view when the commit is issued.
CREATE MATERIALIZED VIEW sum_sales
REFRESH FAST ON COMMIT AS
SELECT s.time_id, COUNT(*) AS count_grp,
SUM(s.amount_sold) AS sum_dollar_sales,
COUNT(s.amount_sold) AS count_dollar_sales
FROM sales s
GROUP BY s.time_id;
Without using the sequence, you will have the following error
ORA-12033: cannot use filter columns from materialized view log on "ADMIN"."SALES"
So let me try to explain why, by using a Testcase
drop table sales;
create table sales (time_id number, prod_id number, amount_sold number)
CREATE MATERIALIZED VIEW LOG ON sales
WITH ROWID, SEQUENCE(amount_sold, time_id, prod_id)
INCLUDING NEW VALUES;
truncate table sales;
insert into sales values (1,1,23);
insert into sales values (1,2,23);
commit;
select time_id, sum(amount_sold) from sales group by time_id;
TIME_ID SUM(AMOUNT_SOLD)
------- ----------------
1 46
Now Imagine, that you will modify a row multiple times.
update sales set amount_sold = 55 where time_id = 1 and PROD_ID = 1;
update sales set amount_sold = 12 where time_id = 1 and PROD_ID = 1;
select time_id, sum(amount_sold) from sales group by time_id;
TIME_ID SUM(AMOUNT_SOLD)
------- ----------------
1 35
your new amount_sold is 35. How to do a fast refresh without reading the value for the row (1,2) because you only modified (1,1)
select * from MLOG$_SALES where DMLTYPE$$ != 'I' order by ;
AMOUNT_SOLD TIME_ID PROD_ID M_ROW$$ SEQUENCE$$ SNAPTIME$$ DMLTYPE$$ OLD_NEW$$ CHANGE_VECTOR$$ XID$$
----------- ------- ------- ------------------ ---------- -------------------- --------- --------- --------------- ----------------
23 1 1 AAAwaSAAAAAAFpTAAA 105 4000-01-01T00:00:00Z U U CA== 4222223434942993
55 1 1 AAAwaSAAAAAAFpTAAA 106 4000-01-01T00:00:00Z U N CA== 4222223434942993
55 1 1 AAAwaSAAAAAAFpTAAA 107 4000-01-01T00:00:00Z U U CA== 4222223434942993
12 1 1 AAAwaSAAAAAAFpTAAA 108 4000-01-01T00:00:00Z U N CA== 4222223434942993
So you can use the previous value 46 and increment/decrement using the old/new value as follow
select 46 - 23 + 55 - 55 + 12 as newval from dual;
NEWVAL
------
35
You can also do the same when doing a delete
This is not possible having only the rowid. To generate the new value 35 you need to read an unmodified value, so you cannot do a fast refresh.
Hope that this can help you to understand in which cases the sequence is used
How do I filter rows those have values in all columns (i.e exclude the row if they have a missing value/null in any of the columns)
Say:
id name age height
------------------------
1 abc 19 NULL
2 fds 34 2.3
3 grt NULL NULL
Output should be only row2. How do I do this?
I have the data as below and ID is VARCHAR2 type
Table Name :EMP
ID TST_DATE
A035 05/12/2015
BAB0 05/12/2015
701 07/12/2015
81 07/12/2015
I used below query to get max of ID group by TST_DATE.
SELECT TST_DATE,MAX(ID) from EMP group by TST_DATE;
TST_DATE MAX(ID)
05/12/2015 BAB0
07/12/2015 81
In the second row it returning 81 instead of 701.
To sort strings that represent (hex) numbers in numeric, rather than lexicographical, order you need to convert them to actual numbers:
SELECT TST_DATE, ID, TO_NUMBER(ID, 'XXXXXXXXXX') from EMP
ORDER BY TO_NUMBER(ID, 'XXXXXXXXXX');
TST_DATE ID TO_NUMBER(ID,'XXXXXXXXXX')
---------- ---- ---------------------------------------
07/12/2015 81 129
07/12/2015 701 1793
05/12/2015 A035 41013
05/12/2015 BAB0 47792
You can use that numeric form within your max() and convert back to a hex string for display:
SELECT TST_DATE,
TO_CHAR(MAX(TO_NUMBER(ID, 'XXXXXXXXXX')), 'XXXXXXXXXX')
from EMP group by TST_DATE;
TST_DATE TO_CHAR(MAX
---------- -----------
07/12/2015 701
05/12/2015 BAB0
With a suitable number of Xs in the format models of course; how many depends on the size of your varchar2 column.
I'm dealing whit this for a couple of hours and I can't find the way to get the answer.
I've a table with a maximun of 4 records for a product (let's call it that way) for a diferent period (column name with a number). I'm trying to return the ones that DO NOT has a particular type of CONSUMPTION_TYPE_ID. But it doesn't work.
I'll explain it simple. I've a table with these fields (there are more, but these one are just fine)
product_id - CONSUMPTION_TYPE_ID - consumption_period
123 103 1
123 104 1
123 107 1
123 108 1
I need to return the ones that don't has one particular type of consumption, let's say that the type 107 is missing (the row doesn't exists), the select query should show the other 3 or any present. I don't mind doing the same select 4 times, I could also try to do a cursor for it and use loop to check every one. The point is, that the type of query with "not in" or "not exists" doesn't work. It gives me a result like the one given below, but when I query the "consumption_period" it shows me the missing "CONSUMPTION_TYPE_ID" and that's because the "not in" clause it's only hidding the results.
this is what I need.
select * from t1 where CONSUMPTION_TYPE_ID != 108;
product_id - CONSUMPTION_TYPE_ID - consumption_period
123 103 1
123 104 1
123 107 1
I hope you can help me with this. I'm stucked, it maybe simple, but I'm having one of those stucked times. Thanks in advance for any help
You probably should've posted that NOT EXISTS query that doesn't work, because that is the right way to do this.
If I got your requirements right: all products that do not have a record for a specific consumption_type_id.
SELECT DISTINCT product_id
FROM t1 t
WHERE NOT EXISTS
(SELECT 1 FROM t1
WHERE t.product_id = product_id
AND Consumption_Type_ID = ?)
The obvious answer here is to search for CONSUMPTION_TYPE_ID = 108 and have the surrounding code check for a lack of rows, rather than the existence of rows.
If you really need a row return for each consumption_type_id that's not in this table, then you should probably be selecting from the lookup table for consumption_type_id:
select *
from consumption_type ct
where not exists (select *
from t1
where t1.consumption_type_id = ct.consumption_type_id)
and ct.consumption_type_id = 108
