PL/SQL :: Multiple Indexes Using Same Columns On One Table?
Oct 4, 2012
I have a table like MyTab(a int, b int), and I am required to create a primary key index and a non-unique index on this table using columns (a,b) in a specific table space.
The back end database is Oracle 10g.
Here's what I have tried so far, needless to say, unsuccessfully.
Alter Table MyTab
Add Constraint c_1 primary key (a, b)
Using Index (Create index mytab_idx on MyTab(a, b))
Using index tablespace results_index
So my question are:
1. is this is possible? if so, what is the correct syntax.
2. assuming it is possible, using this sort of construct before? it appears to be conflicting and inconsistent to me.
I am attempting to select back multiple values for a specific key on one row. See the example below. I have been able to use the sys_connect_by_path to combine the fields into one field but I am unable to assign them to fields of their own. See the example below
TABLE DETAILS: Policy id plan name 111 A Plan 111 B Plan 111 Z Plan 112 A Plan 112 Z Plan
My desired result is to be able to show the output as follows
Policy ID Plan_1 Plan_2 Plan_3 111 A Plan B Plan Z PLan 112 A Plan Z PLan
I am new to oracle, I have request to build a query,
we have table that generates data from 7am to 20pm for eavery hour it generates 4 rows and has 43 session values as 43 columns.
Now i want to find for every hour which is the hights session value at what time. in one hour it runs four times like 7, 7:15, 7:30 and 7:45 and each row has date, time and 43 session columns in table...
How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5 23 asdc 1 Location USA NM ABQ Four Seasons 87106 23 asdc 1 Stats 2300 91.7 8.2 85432 23 asdc 1 Audit 1996 June 17 1200 65 affc 2 Location USA TX AUS Hilton 92305 65 affc 2 Stats 5510 42.7 46 9999 65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime 23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200 65 affc 2 USA TX AUS Hilton 92305 5510 42.7 46 9999 1996 July 172 1100
I have a query to pull the first contact of students.
The table has all contacts like parent/guardian, friends family, emergency contact etc.
I would like to the first primary contact in this order, 1. initial contact, 2. same as student address and also have to be parents, 3. live with and also a parent, 4. parents 5. friends.
I don't know how to pull 2 and 3 . because it looks like it needs to concatenate the columns.
here is my initial query
Select Min(U2.Id) Keep (Dense_Rank First Order By U2.Initial_Contact Desc, U2.Same_As_Students_Address Desc,u2.lives_with DESC,U2.Guardian Desc) From Contacts
how to achieve 2 and 3?
The table script is attached. All the above columns are 1 or 0.
I am trying to validate a monthly report so was trying to write queries to get different criteria into one table. So my first query returns all the product,second query returns all the enrolled customers, 3rd query returns all the cancelled customers and 4th query returns all the newly enrolled for a month. Is there a way I can pass the first query results into 1st column, 2 query results into 2nd column, 3 query results into 3rd column and so on.
I tired writing the SQL several different ways and have spent a day on it and still cannot figure it out. I am using SQL Developer.
I have a table with Column A, B, C. I want to write a query to retrieve the top row of A, B combination. i.e, for every unique value of A,B combination I want the row having highest value for C. I tried using rank() function but am not able to get the top row with combination of A,B.
select * from nrc_trans_descr where type_id_nrc=60013 -- it has 18 columns and i have hard coded 60013 for simplification here.60013 is derived from 3 other table Output is ( it can have many rows too.typically for each type_id_nrc there is one row ).
TYPE_ID_NRC TRIGGER_STATUS INSTALLMENT_TYPE_ID_NRC --------------------------------------------------------------------- 60013 0 61013 i have to pass TYPE_ID_NRC and INSTALLMENT_TYPE_ID_NRC to restriction_id column in a different table. currently i am doing like this select * FROM DISCOUNT_RESTRICTIONS WHERE discount_id in (12085,12086) and (restricted_id in ( select type_id_nrc from nrc_trans_descr where type_id_nrc=60013) or restricted_id in ( select installment_type_id_nrc from nrc_trans_descr where type_id_nrc=60013));
am using ORACLE 10GR2(solution for 11gr2 is welcome too)
ID Status description Tracking ID 1 Strat Frog 1 2 Start Dog 2 3 Process Frog 1 4 Completed Dog 2 5 Start Rabbit 3 6 Error Frog 1 7 Stop Rabbit 3 8 Start Elephant 4 9 process Elephant 4 10 Start Human 5 11 Stop Human 5 12 Start Butterfly 6 13 completed Butterfly 6 14 start lion 7 15 error lion 8 16 complted lion 8 17 start tiger 9 18 error tiger 9
select * from Table-Name where datetime < to_date('2012/12/06:06:00:00', 'yyyy/mm/dd:hh24:mi:ss') And datetime > to_date('2012/12/04:22:00:00', 'yyyy/mm/dd:hh24:mi:ss')And not description in (Select * from Table-Name where Status like ('%Complete%' or Status like '%stop%') and description in (Select description from Table-Name where Status Like '%start%'));
Result should be " Frog and Elephant and tiger"
Start of every record(descrpition --status is Start) End of every record ( status is stop or done or completed) status process is in btwn (their will be mulitple records with name s//y to process...ie. process 1 ...process 2...process 3 )
I've read so many different pages on this topic but I can't seem to get my query the way it needs to be. Here's the query:
select admitnbr, lastname||', '||firstname||' '||finitial, hphone, mobile, wphone, med_rec, dob from patients join schedule using (key_patien) join adtmirro using (key_patien) where appt_state = 'ON HOLD'
Because patients in my database can have multiple appointments "on hold" there are duplicates in the results. I only need 1 record per patient in order to forward this information into an automated dialer to contact that patient. I do NOT want to call the patient over and over again. Once will suffice. I'm trying to make a distinction on the column 'med_rec'. One row per 'med_rec' will be awesome but I can't find a way to create a distinct on that column.
i have downloaded ireports latest version (3.6.0) for working with jasper reports (3.5.2) and creating reports;How can I change the orientation of a 4 columns report in order to generate the columns starting from the right side.I need to generate a multiple columns report in arabic and it should be done from right to left.
I need to write a script which copies 4 col data from one table to another table. there are three tables
cwat_curr_mst and cwat_assigned_customer and cwat_assignment_mst. Cwat curr mst has PK curr_id and cwat_assigned_customer has PK assignment_id. Also cwat_assigned_customer has customer_id. In cwat_assignment_mst has Curr_id and Assignment_ID.
cwat_curr_mst and cwat_assigned_customer tables has 4 cols in common they are ASRT_SNM_NO, SNM_NO, FLORIDA_NO, CBRN_NO.
So from curr_mst all these 4 cols data needs to come/copy into cwat_assigned_customer.
the thread title was a bit confusing, couldn't come up with anything short to describe the question. What I am looking for is a query which will put records into groups based on matching values in one of two columns. So if two records have a matching value in column 1 or column 2 they are in the same group. See the example bellow and expected output for a "better" explanation:
--setup CREATE TABLE foo (foo_id NUMBER NOT NULL PRIMARY KEY, record_number NUMBER, record_value VARCHAR2(1));
[Code]...
--expected output
group# foo_id record_number record_value 1 1 1 A 1 2 1 B 1 3 2 B 1 4 2 C 2 5 3 D 3 6 4 E 3 7 5 E
My initial thought is that is feels a little bit like the sequential seat problem but not quite close enough. I know it could be done iteratively with PL/SQL but I am thinking there must be a way to do it in SQL I am not seeing yet.
I want drop some old partitions from big table but this will not increase free space on disk. So I want to move table with indexes to anothers tablespaces. What is the fastest way to do that? ALTER TABLE ... MOVE TABLESPACE ...? CTAS ? Or something else?
create index datastores_text on test_url_search ( doc ) indextype is ctxsys.context parameters ( 'Datastore TEST_URL' );
SELECT SCORE(1),DOC from TEST_URL_SEARCH WHERE CONTAINS(DOC, 'London', 1) > 0
This works. i like to more
e.g. multi words search e.g. ' London Games' where if London or games are present it return a URL with a score,
or
Search in the Chinese.
The only way I can see to do this is create different indexes as the attributes for 'URL_DATASTORE' are limited. If I can what does the 'Contains' statement look like?
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)
