SQL & PL/SQL :: Display Date Ranges In One Column As Separate Date Periods (start And End Date) In Two?
Jun 1, 2010I'm trying to work out how to take a table like this:
IDDate
12502-Feb-07
12516-Mar-07
12523-May-07
12524-May-07
12525-May-07
33302-Jan-09
33303-Jan-09
33304-Jan-09
33317-Mar-09
And display the data like this:
IDPeriodPeriod StartPeriod End
125102-Feb-0702-Feb-07
125216-Mar-0716-Mar-07
125323-May-0725-May-07
333102-Jan-0904-Jan-09
333217-Mar-0917-Mar-09
As you can see, it's split the entries into date ranges. If there is a 'lone' date, the 'period start' and the 'period end' are the same date.

Can Partition A Table Based On Date If It Does Not Have A Date Column
Jun 21, 2012How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.

SQL & PL/SQL :: Querying Flattened Dimension Table?
Apr 21, 2012I have flattened customer dimension table and I would like to query it with other dimension table like address. I write a query, where I join address table twice to get permanent, secondary, and work addresses, but customer and address tables are huge that causing performance issue. Is any other ways to join flatten table with address dimensions than join it twice.
CREATE TABLE CUSTOMER

Remove Duplicates From Slowly Changing Dimension
Jun 6, 2013I've got a slowly changing dimension table for products with some duplicate attributes -
UNIQUE_ID | DATE_FROM | DATE_TO | PRODUCT_ID | ATTRIBUTE_1 | ATTRIBUTE_2
1 01-JAN-13 02-JAN-13 423 MONKEY 5
2 03-JAN-13 04-JAN-13 423 MONKEY 5
3 05-JAN-13 08-JAN-13 423 MONKEY 4
4 09-JAN-13 10-JAN-13 423 SUPERMONKEY 4
5 01-JAN-13 08-JAN-13 378 BANANA 2
6 09-JAN-13 10-JAN-13 378 BANANA 3
The natural key should be PRODUCT_ID, ATTRIBUTE_1 and ATTRIBUTE_2. The table should therefore be recreated as follows:
UNIQUE_ID | DATE_FROM | DATE_TO | PRODUCT_ID | ATTRIBUTE_1 | ATTRIBUTE_2
1 01-JAN-13 04-JAN-13 423 MONKEY 5
2 05-JAN-13 08-JAN-13 423 MONKEY 4
3 09-JAN-13 10-JAN-13 423 SUPERMONKEY 4
4 01-JAN-13 08-JAN-13 378 BANANA 2
5 09-JAN-13 10-JAN-13 378 BANANA 3
Create Dimension - Functional Dependency Between Levels
Sep 28, 2010the literature equates dimension hierarchies with fuctional dependencies between the levels. I like to tst the strength of this assumption with the implementation of 'CREATE DIMENSION' which allows you to create roll-up hierarchies.
My question to put it simply is this: Given:
CREATE DIMENSION location_dim
LEVEL location IS (location.loc_id)
LEVEL city IS (location.city)
LEVEL state IS (location.state)
HIERARCHY geog_rollup (
location CHILD OF
city CHILD OF
state CHILD
)
Can I insert the following rows into the dimension:
loc_id, city, state
1, Epping, NSW
2, Epping, VIC
Please note that the two Eppings are different cities.
Given the roll-up hierarchy City -> State, will it require that for every city there can be only one state in which case the FD between City and State cannot hold. Or, is it that the roll-up hierarchy defined here has nothing to do with FD.
The second part of the question is if the answer to the above question is that the roll-up is not the same as FD, then is the ATTRIBUTE clause meant to define the n:1 (functional dependency) instead?
SQL & PL/SQL :: Creating DWMQY Dimension Using Analytic Workspace Manager
Nov 20, 2012I am creating a "time aware" (DAY, WEEK, MONTH, QUARTER, and YEAR) dimension using Analytic Workspace Manager.
Let me give you some background. I'm coming from a traditional "Oracle Express" OLAP background where all our data is stored in cubes and these are defined, populated and operated on using OLAP DML, there is no SQL or traditional relational tables involved.
I now want to pull data from relational tables into some OLAP cubes and am using Analytic Workspace Manager to do this (maybe this is not the best way?)
Let me explain what I'm trying to achieve. In OLAP worksheet I can type the following DML commands:
DEFINE MY_DAY DIMENSION DAY
MAINTAIN MY_DAY ADD TODAY '01JAN2011'
What this will do is create a "day dimension" and will populate it with values for each and every day between 1st Jan 2011 and today. It will be fully "time aware" and thus you can use date functions such as DAYOF to limit the MY_DAY dimension to all the Fridays etc. Similarly if I define a "month dimension" there will be an automatic implicit relationship between these two dimensions, this relationship and time aware cleverness is built into Oracle.
However, a dimension defined using DML commands (and indeed all objects created using DML language) is not visible in Analytic Workspace Manager (as there is no metadata for them?) and for the life of me I cannot work out how to create such a dimension using AWM. If I create a "Time Dimension" then, as far as I can tell, this is not a proper time dimension but merely a text dimension and I, presume, I have to teach it time awareness.
I have no issues creating, and populating cubes from relational tables using Analytic Workspace Manager, the only issue I have is creating a "proper" time aware dimension.
Use Range-hash Partitioning Of A Large Dimension Table
Apr 12, 2013At moment we use range-hash partitioning of a large dimension table (dimension model warehouse) table with 2 levels - range partitioned on columns only available at bottom level of hierarchy - date and issue_id.
Result is a partition with null value - assume would get a null partition in large fact table if was partitioned with reference to the large dimension.Large fact table similarly partitioned date range-hash local bitmap indexes
Suggested to use would get automatic partition-wise joins if used reference partitioningWould have thought would get that with range-hash on both dimension.
SQL & PL/SQL :: Debugging Stored Procedure / Populate Data Warehouse Dimension
Nov 20, 2011The following code is a stored procedure I plan to use to populate a Data Warehouse dimension using data from two OLTP tables which already exist in my database. Notice that in my cursor select statement, I calculate an attribute using substr and instr, and I also assign a true or false value to a flag using a CASE statement.
CREATE OR REPLACE PROCEDURE populate_product_dimension
AS
v_Count NUMBER := 0;
v_NumRecs NUMBER;
/*Declare a cursor on the following query which returns mulitple rows of data from product and price_hist tables*/
[code]....
In my mind, Product_Code is declared correctly in the Cursor declaration Select statement.
SQL & PL/SQL :: Converting Number Column To Date Column
Dec 25, 2012I have a partitioned table with ~50 million rows that was setup with a number(10) instead of a date column. All the data in the table is ALWATS in this format YYYYMMDD
CREATE TABLE T1.monthly
(
SEQ_NUM NUMBER(10) NOT NULL,
DAY_DK NUMBER(10) NOT NULL
)

PCTUSED 0
PCTFREE 10

some sample data
SEQ_NUM DAY_DK

990 20121225
991 20121225
992 20121225

When I use the exchange partition method the parition is able to move the data from "monthly" table to "mth" table.
desc t1.mth; ### my temorary table
Name Null? Type
----------------------------------------- -------- ----------------------------
SEQ_NUM NUMBER(10)
DAY_DK NUMBER(10)
Than when I try to alter my temp table "mth". I get an error table must be empty to change column types.
alter table n546830.mth modify (DAY_DK date);
Next I tried making my temporary table "mth" a date column. When I an the exchange partition command I get the following error:
alter table t1.monthly exchange partition DEC_2012
with table t1.mth without validation;
alter table n546830.monthly exchange partition DEC_2012 with table n546830.mth without validation
*
ERROR at line 1:
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION
Method I can use to convert a number(10) to date column and keep the information in a table. Note, I don't care about HH:MM:SS as I never had that information to begin with and would be happy to set that part of the date column to all zeroes "00:00:00"

2. The search criteria from the weba application (ADF) is based on the date, user gives the range.
3. From ADF I am referring to it as sql.Timestamp when building the query.
