I have created a classic report region (REGION: REPORT_FILTER_SHOP_TYPE).
That has a SQL below this.
SELECT
ID, SHOP_NAME, SHOP_TYPE, OPEN_YEAR, CITY
FROM SHOP_LIST;
I want to apply a filter to this table. The filter criteria will be selected from the list item. And this page have some lists.
For example, if there is no filter, the SQL right above one. But if the "SHOP_TYPE" and "OPEN_YEAR" are selected, execute the SQL below.
SELECT * FROM (
SELECT
ID, SHOP_NAME, SHOP_TYPE, OPEN_YEAR, CITY
FROM SHOP_LIST
) S
WHERE S.SHOP_TYPE = 'BOOKSTORE' AND S.OPEN_YEAR <2010;
I can now create the compose SQL text from selected list items.
What do I need to set to display this result in REPORT_FILTER_SHOP_TYPE?
Well, most probably not like that; why using parameters on a page if you hardcode some values into report's query? Use parameters!
Something like this:
SELECT id,
shop_name,
shop_type,
open_year
FROM shop_list
WHERE ( shop_type = :P1_SHOP_TYPE
OR :P1_SHOP_TYPE IS NULL)
AND ( open_year < :P1_OPEN_YEAR
OR :P1_OPEN_YEAR IS NULL);

I need to create a view contains BSB#, customer#, name from customer, and account#, type, balance from account.
I tried this select statement:
select customer.bsb#, customer.customer#, customer.name, account.account#, account.type, account.balance
from customer
left outer join account on customer.bsb# = account.bsb#
and customer.customer# = account.customer#;
And the output is like this:
output
However, I need to make the out like:
display
So, how could I remove the duplicate results from certain columns?
I can't create my view and I don't know how to fix it.
when trying to create the view it tries to add all the columns from select to the group by, which isn't what I want. and doesn't work anyways
CREATE OR REPLACE FORCE VIEW CustomerSaleHistoryView AS
Select SALE.SaleID,
SALE.SaleDate,
CUSTOMER.LastName,
CUSTOMER.FirstName,
SALE_ITEM.SaleItemID,
SALE_ITEM.ItemID,
ITEM.ItemPrice,
SUM(SALE_ITEM.ITEMPRICE),
AVG(SALE_ITEM.ITEMPRICE)
from customer
join sale on customer.CUSTOMERID = Sale.CUSTOMERID
join sale_item on sale_item.saleid = sale.saleID
join item on sale_item.itemID = item.itemID
group by CUSTOMER.LastName, CUSTOMER.FirstName, SALE.SaleID;
In order for you query to work you MUST group by any columns that are not being aggregated with a formula like SUM() or AVG(). In your case GROUP BY SALE.SaleID, SALE.SaleDate, CUSTOMER.LastName, CUSTOMER.FirstName, SALE_ITEM.SaleItemID, SALE_ITEM.ItemID, ITEM.ItemPrice
What are you trying to accomplish that you don't believe this GROUP BY is appropriate?
When using group by clause the list of columns that you are selecting should be either part of the group by clause or they should be part of an aggregate function. In your case SALE.SaleDate, SALE_ITEM.SaleItemID, SALE_ITEM.ItemID and ITEM.ItemPrice doesn't satisfy that rule. You need to include these to your group by clause. Once you fix the select statement and when it returns the desired output convert that into a view.
I have a query like below - table names etc. changed for keeping the actual data private
SELECT inv.*,TRUNC(sysdate)
FROM Invoice inv
WHERE (inv.carrier,inv.pro,inv.ndate) IN
(
SELECT carrier,pro,n_dt FROM Order where TRUNC(Order.cr_dt) = TRUNC(sysdate)
)
I am selecting records from Invoice based on Order. i.e. all records from Invoice which are common with order records for today, based on those 3 columns...
Now I want to select Order_Num from Order in my select query as well.. so that I can use the whole thing to insert it into totally seperate table, let's say orderedInvoices.
insert into orderedInvoices(seq_no,..same columns as Inv...,Cr_dt)
(
SELECT **Order.Order_Num**, inv.*,TRUNC(sysdate)
FROM Invoice inv
WHERE (inv.carrier,inv.pro,inv.ndate) IN
(
SELECT carrier,pro,n_dt FROM Order where TRUNC(Order.cr_dt) = TRUNC(sysdate)
)
)
?? - how to do I select that Order_Num in main query for each records of that sub query?
p.s. I understand that trunc(cr_dt) will not use index on cr_dt (if a index is there..) but I couldn't select records unless I omit the time part of it..:(
If the table ORDER1 is unique on CARRIER, PRO and N_DT you can use a JOIN instead of IN to restrict your records, it'll also enable you to select whatever data you want from either table:
select order.order_num, inv.*, trunc(sysdate)
from Invoice inv
join order ord
on inv.carrier = ord.carrier
and inv.pro = ord.pro
and inv.ndate = ord.n_dt
where trunc(order.cr_dt) = trunc(sysdate)
If it's not unique then you have to use DISTINCT to deduplicate your record set.
Though using TRUNC() on CR_DT will not use an index on that column you can use a functional index on this if you do need an index.
create index i_order_trunc_cr_dt on order (trunc(cr_dt));
1. This is a really bad name for a table as it's a keyword, consider using ORDERS instead.
I want to create a Hive UDF function that returns specific column names based on some value say retreivecol(age).If the age is 20 then return the list of column names to be used in select query like 'name,email,fbuserid,friend list ' etc and if the age is less than 20 return 'name' alone.So I want my HIVE QL query to look like
select retreivecol(age) from User_Data;
The above query just prints the name of the columns like 'name,email,fbuserid,friendslist' etc as opposed to treating them as column names and filtering based on the same.Any pointers are appreciated.
I'm not sure a UDF is the right place to do this, as UDF's simply see the value passed to them, they don't really have access to the whole table structure.
Instead, could you do this in a nested table?
select name,email,id FROM
(
select
name,
if(age < 20, email, NULL) as email,
if(age < 20, id, NULL) as id
FROM mytable
) a
my table looks like this:
If the field name contains cost or quantity for the same lineItemIds, I have to display the result as:
cost is changed from 8*1=8
(fromVal*fromVal) to 9*6=54
(toVal*toVal) for itemID 123.
any help will be appreciated.
SELECT tc.LINE_ITEM_ID ITEM_ID,
tc.FROMVAL COST_FROMVAL,
tq.FROMVAL QTY_FROMVAL,
(tc.FROMVAL*tq.FROMVAL) PROD_FROMVAL,
tc.TOVAL COST_TOVAL,
tq.TOVAL QTY_TOVAL,
(tc.TOVAL*tq.TOVAL) PROD_TOVAL,
FROM
(SELECT LINE_ITEM_ID,
FROMVAL,
TOVAL,
FROM table
WHERE FIELDNAME = 'cost') tc
JOIN (SELECT LINE_ITEM_ID,
FROMVAL,
TOVAL,
FROM table
WHERE FIELDNAME = 'quantity') tq
ON tc.LINE_ITEM_ID = tq.LINE_ITEM_ID
I would look into using product aggregate functions. You'll have to compile them yourself though, Oracle doesn't include them as system functions. http://radino.eu/2010/11/17/product-aggregate-function/
If it's just for this one case where cost or quantity are used, then you could also just use subqueries, or temporary transaction based tables.
I'd provide you with a query example, but unfortunately don't have an Oracle instance accessible presently.
