I am trying to write a single SELECT statement that groups at 2 levels of aggregation (using grouping sets) and assigns row numbers (to rank each item) that are partitioned at the correct level for each grouping set. I have the grouping sets figured out but I can't find a way to make Partition By match each level of aggregation.
What I am looking for (in a single SELECT statement) is logically equivalent to:
SELECTweek ,region ,NULL as country ,item ,SUM(qty) ,ROW_NUMBER OVER (PARTITION BY week, region ORDER BY SUM(qty) DESC) as rownumFROM base GROUP BY week ,region ,item UNION ALL
SELECTweek ,NULL as region ,country ,item ,SUM(qty) ,ROW_NUMBER OVER (PARTITION BY week, country ORDER BY SUM(qty) DESC) as rownumFROM base GROUP BY week ,country ,item
I hoped that I could do something like this:
SELECTweek ,region ,country ,item ,SUM(qty) ,ROW_NUMBER OVER (PARTITION BY week, GROUPING SETS (region, country) ORDER BY SUM(qty) DESC) as rownumFROM base GROUP BY week ,GROUPING SETS (region, country) ,item
But it looks like I am not allowed to partition by grouping sets -- I get the error ORA-00907: missing right parenthesis. I didn't expect it to work but I am not sure how else to partition by multiple levels.
let me know if I could have tagged my code or met other forum standards better.
Is it possible to create trigger on the various tables and views exists (i.e. dynamic performance views) in data dictionary, when ever any DML operations performs by Oracle it self?
I have a created a materialized view which is based on a view on remote database. Now how do I refresh the view.
Materialized view is created by
CREATE MATERIALIZED VIEW mv_employee_name AS SELECT EMPLID, EMPL_NAME FROM VEMPDATA@REMOTEDB WHERE REGION = 'US';
I am wondering how the refersh happens or how do I specify the refresh clause.REFRESH FAST option is looking for VIEW LOG on the master table but in this case its a remote view, so I cannot create any object on remote db.
I am removing sal column from table tab_emp; i want to check whether any materialized view or view using this column by querying using data dictionary :- if i use like condition against query column of all_mviews it is throwing error sicne it is long data type. is there a way to search it without creating any function and use it in a query.
I have to convert some existing materialized views (fast refresh) to partition materialized views.
Database version is oracle 10.1.0.4. I have decided to use on prebuilt table option to do the partitioning as it minimizes the time to transfer from the master site.
1) stop replication 1) create interim tables with similar structure as the materialized views 2) transfer all data from the materialized views to the interim tables 4) script out the materialized views structure and add in on prebuilt table option in the scripts 5) drop the materialized views 6) rename the interim tables with the same name as the materialized views 7) run the scripts to create the materialized views with on prebuilt table option 8) refresh the newly created materialized views -> it should take a short time since I am using on prebuilt table option
But I am facing one major issue. That is if I drop the materialized views, the materialized view logs of the master tables are purged. When the materialized views are refreshed fast, there are some data missing. the data that are purged out when the materialized view are dropped.
Do you happen to know other ways that existing materialized views can be converted to partitioned materialized views? Do you have any workaround to prevent the materialized view logs from being purged?
I need to populate a table based on the results of comparing sets of data. I decided to do this using MULTISET EXCEPT, but having created the structure, do not know whether it is actually possible, and if so, what syntax to use.
I have created:
CREATE OR REPLACE TYPE NUMBER_TBL IS TABLE OF NUMBER; /
CREATE OR REPLACE TYPE PACKAGE_OPTION_GROUP_OBJ AS OBJECT( ID NUMBER, benefits NUMBER_TBL ) /
CREATE OR REPLACE TYPE PACKAGE_OPTION_GROUP_TBL AS table of PACKAGE_OPTION_GROUP_OBJ /
I am expecting the result to be something like: ***comparisonTable*** GROUP_ID : 123 BENEFITS : 165 BENEFITS : 167 ---------------------------
However, I don't know if this is possible and if so, what the syntax would be.
At a later stage, I will need to compare the benefits between selectedTable and groupTable, where the GroupID's match, which is why I have the tables structured in this way.
I have two queries. One selects 5 values (all number datatypes), the second query selects 2 values (both number datatypes).If a value from query 2 exists in the resultset of query 1 - go make table updates using the second value in the select statment of query 2. If there is not a match, update a table with values from query 1.
Currently, I have two cursor for loops, which are nested. This works but of course is horribly slow. What is a better way to process this data?The number of rows varies between the two resultsets.
have two queries that will return same columns from two different set of tables ( column mapping has been taken care of). The return type is out ref cursor. (P_SUPPLY_REORDER )
Query-2 Xcom -------------------------------------- select null as sMO_NO, xso.created_date as SPLY_ORD_DT, xso.fk_cust_id as cust_id, cust.cust_po_no as cust_PO_NO ,(sta.SHIP_TO_ATTN_FIRST_NAME||''||sta.SHIP_TO_ATTN_LAST_NAME) as attention_name, xsol.CARTONS_ORDERED as SPLY_ORD_QTY, [code].......
Now the requirement is One of four conditions are possible for each Supply Reorder Number:
. Both table queries return no records- Populate all the P_SUPPLY_REORDER output fields with nulls . SUPPLY_ORDER returns a record, but XCOM_ORDER_HEADER returns no records - Populate output fields with values from the join of SUPPLY_ORDER and SUPPLY_ORDER_LINE. . SUPPLY_ORDER returns no records, but XCOM_ORDER_HEADER returns one record - Populate output fields with values from the join of XCOM_ORDER_HEADER and XCOM_ORDER_LINES. . SUPPLY_ORDER returns a record, and XCOM_ORDER_HEADER returns a record; find out the latest order by comapring max(SPLY_ORD_DT) from SUPPLY_ORDER with max(CREATED_DATE) from XCOM_ORDER_HEADER. - If the latest order is in SUPPLY_ORDER, then populate output fields with values from the join of SUPPLY_ORDER and SUPPLY_ORDER_LINE. - If order dates are equal from both join results, then populate output fields with values from the join of SUPPLY_ORDER and SUPPLY_ORDER_LINE. - If the latest order is in XCOM_ORDER_HEADER, then populate output fields with values from the join of XCOM_ORDER_HEADER and XCOM_ORDER_LINES.
Question is how can we switch over the queries to pull respective dataset based on these conditions ( checking that which table join is going to return a row and then based upon latest order if both tables return a row) and all this logic as part of single SQL statement that is returned as OUT Ref Cursor.
i basically need to setup a schema for globalization. i need to handle brittish dollar signs, american dollar signs. etc.what is a global character setting i can use to handle almost everything?
my problem right now is that when i store a brittian dollar sign it converts it to a box. i need this preserved so i can select it and use it later.will the WE8ISO8859P1 character setting work? where is a good place to view all of the types of character settings? and what they are for. etc. and also how do you change such things? not for the session, but for a schema wide
here are my current sessions
NLS_LANGUAGE AMERICAN NLS_TERRITORY AMERICA NLS_CURRENCY $ NLS_ISO_CURRENCY AMERICA
I know how to select the last N sets of rows, using DENSE_RANK - where multiple rows have the same timestamp but I want to only select those rows which do NOT have the top 2 unique timestamps.
i.e.:
SELECT * FROM ( SELECT DENSE_RANK() OVER (ORDER BY myTimestamp DESC) DENSE_RANK, HISTORYID, USER_ID, myTimestamp, STATUS, FROM TXN_HIST) WHERE DENSE_RANK > 2 order by myTimestamp DESC, HISTORYID, USER_ID;
The below sql is giving different number of result sets while adding further columns in select clause.i.e After adding the columns 4,5,6 in the below query its giving different number of result set.In this case the result set count would be 5.
Before adding the columns 4,5,6,the result set count was 11.
I've got one database which was Initially upgraded from Oracle 8i to 10.2.04 running on windows. Most of the tabespaces are Dictionary managed. Do you think moving them to locally managed tablespace would give me better performance?
if Yes, what approach I should apply to move them to locally managed? I would like to do this with minimum/no downtime.
Question 1) I have read the following statement in a PL/SQL book.
Quote:To check whether an existing procedure is compiled for native execution or not, you can query the following data dictionary views:
[USER | ALL | DBA]_STORED_SETTINGS [USER | ALL | DBA ]_PLSQL_OBJECTS
However, I when i query the view USER_PLSQL_OBJECTS I get the following error message:
Quote:ORA-00942: table or view does not exist
Question 2) I have read the PLSQL_WARNING can be set to DEFERRED at the system level. However, I am unable to defer it. tell me how to apply defer caluse to following statement:
Quote:ALTER SYSTEM SET PLSQL_WARNINGS ='DISABLE:ALL'
I created a materilaized view with partitions and i need to add partitions dynamicaaly using stored procedure for that i need to check whther the partiions with the same name existing.where can i see the partition names for a materilaized view is there any table like "USER_TAB_PARTITIONS"?.if the same query exists in the forum
I have a requirement to get the records group wise.Ex: For each departments, i need to get the employee details as a coma seperated.It means that the output must have the department name in first column and the second column must contain all the employees in that particular department (As a coma seperated).
In the below data, a container is moving from one city to another. 1,2 ,3 can be any number which i want to generate and use as keys to group the cities. Eg: AUH, JEB, CIW belong to the same key=2; SIN, IKT belong to a new group 4. The City where difference between the Seq# is greater than 1 (eg between S8W and AUH), a new group starts.

How can I get the grp_id for unique combination of manager and department, grp_id should be created on asc order of manager_id. In this example manager_id 100 is minimum, so it should be grp 1 and all the employees with that manager_id should be in grp_id 1, for manager_id 114 grp_id should be 2.
If, there is manager_id 117, it should create grp_id 3.
To get grp_num ,I can use row_number() over (partition by department_id,manager_id order by employee_id) grp_num

I have a procedure in my schema. I have created a sys context name xyz for passing the date in that i am passing the sysdate to that context which is used in a view.i have used/called that procedure in form.
My problem is that when i am giving Grant select any dictionary to the user then form is compiled otherwise form is giving error procedure name must be declared. But for security reasons i don't to give select any dictionary to that user.
