SQL & PL/SQL :: How To Make Return All Records Except Duplicates
Mar 29, 2010I have a table like this basic example:
ID Product Color Time-In
1 Apple Green May
2 Apple Red April
3 Pear Green May
4 Pear Green April
5 Plum Blue June
In SQL I want to return all 4 fields of the records except those records where Product and Color are identical - in that case it should return the latest (by name of month - preferred) or just the first it finds
So I should get these
1 Apple Green May
2 Apple Red April
3 Pear Green May
5 Plum Blue June
If I do a select distinct then I will only get those fields I test on (product and color), not the rest.
SQL & PL/SQL :: To Compare Records In Two Columns
Oct 8, 2010I need to compare records in the two columns (varchar). I need to find almost the same names from that columns.
For instance:
'MAPE STUD' <-> MAPE STUDY
And I should see that these records are the same because different is only in the one word.
SQL & PL/SQL :: Max Date Using Selected Columns - Millions Of Records
Dec 16, 2011I am having a requirement like below,
Scene 1:
If duplicate records found for SSN,BWE with SAME DATE_CREATED than take the record with HIGHEST DATE_MODIFIED.
Table Structure:
SSN BWE DATE_CREATE DATE_MODIFIED

SQL & PL/SQL :: Displaying Record When All Columns Have Matching Records?
Jul 3, 2012I need to display the record when all the columns have matching records,If one of them doesn't match then it should not be displayed
The following is the example
WITH t1 as
(select 159435 ky from dual)
,t3 as
(select 78 id ,'Z-' rk,'SL' cd from dual union all
select 78 id ,'Z+' rk,'SL' cd from dual union all
select 78 id ,'Z-' rk,'SL' cd from dual union all
[code].....
In the above data bg.rk= 'Z-' but one of the record in T3 is having Z+ ,So this should not be displayed (same condition with column CD) in this example cd column in both table matches I tried like above query but i'm getting the record.

View 4 Replies View RelatedPerformance Tuning :: Index 15 Columns When Cannot Predict Columns Will Be Used In Where Clause?
Apr 4, 2011I am running a fairly busy Oracle 10gR2 DB, one of the tables has about 120 columns and this table receives on average 1500 insertions per second. The table is partitioned and the partitioning is based on the most important of the two timestamp columns. There are two timestamps, they hold different times.
Out of these 120 columns, about 15 need to be indexed. Out of the 15 two of them are timestamp, at least one of these two timestamp columns is always in the where clause the queries.
Now the challenge is, the queries we run can have any combination of the 13 other columns + one timestamp. In reality the queries never have more than 7 or 8 columns in the where clause but even if we had only 4 columns in the where clause we would still have the same problem.
So if I create one concatenated index for all these columns it will not be very efficient because after the 4th or 5th column the sorting would no longer be very useful and I believe the optimiser would simply not use the rest of the index. So queries that use the leading columns of the index in sequence work well, but if I need to query the 10th column the I have performance issues.
Now, if I create multiple single column indexes oracle will have to work a lot harder to maintain all these indexes and it will create performance issues (I have tried that). Besides, if I have multiple single column indexes the optimiser will do nested loops twice or three times and will hit only the first few columns of the where clause so I think it will kind of be the same as the long concatenated index.
What I am trying to do is exactly what the Bitmap index would do, it would be very good if I could use the AND condition that a Bitmap index uses. This way I could have N number of single column indexes which the optimiser could pick from and serve the query with exactly the ones it needs. But unfortunately using the Bitmap index here is not an option given the large amount of inserts that I get on this table.
I have been looking for alternatives, I have considered creating multiple shorter concatenated indexes but this still would not address the issue since many queries would still not be served properly and therefore would take a very long time to complete.
What I had in mind would be some sort of multidimensional index, I am not even sure if such thing exists. But essentially it would be some sort of index that could serve a query efficiently regardless of the fact that the where clause has the 1st, 3rd and last columns of the index.
So considering how widely used Oracle is and how many super large databases there are out there, this problem must be common.

SQL & PL/SQL :: Oracle 10g - Update Records In Target Table Based On Records Coming In From Source
Jun 1, 2010I am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE:
CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT
(
CALENDAR_KEY INTEGER NOT NULL,
DAY_TIME_KEY INTEGER NOT NULL,
SITE_KEY NUMBER NOT NULL,
RESERVATION_AGENT_KEY INTEGER NOT NULL,
LOSS_CODE VARCHAR2(30) NOT NULL,
PROP_ID VARCHAR2(5) NOT NULL,

SQL & PL/SQL :: Function In Oracle To Select Not-null Columns At Beginning And Null Columns At End?
Jul 12, 2012I have 8 columns. Some of them might be null.I want to display all 8 columns in my result. Not null columns will be first and null at the end.Here is a sample data :

1 aaa ddd d1 100 6 180
2 bbb ccc 120 169
3 dfe d2 5.9 223

SQL & PL/SQL :: Returning List Of Records That Do Not Have Associated Records From A Sub-query
Sep 6, 2010I am running a query in our Clarity PPM database to return a list of all Support projects. This returns a simple list of project code and project name:
The query has the project resource tables associated with it, so I am able to list all resources allocated to the project. But for now i am only selecting a DISTINCT list of projects.
Query for anyone interested:
Select distinct
Project_code,
project_name
from
niku.nbi_project_current_facts nbip,
niku.odf_ca_project cst,
niku.prtask t,
[code]........
I have a separate query which returns a list of support resources.
select res.full_name, res.unique_name , dep.description
from niku.srm_resources res,
niku.pac_mnt_resources pac,
niku.departments dep
where res.unique_name = pac.resource_code
and pac.departcode = dep.departcode
and res.is_active = 1
and description like 'IMS%'
and UPPER(dep.description) like '%SUP%'
What I need to be able to do in the first query, is return only projects that do NOT have a resource that appears in the resource list in the second query.
(the res.unique_name field in the second query can be linked to the same in the first query)
Logically, the process would be:
1. Identify Support Project
2. Identify Resources allocated to the project team
3. Compare with List of Support Resources
4. If any Resources in that list do NOT appear on the project, then return project.
SQL & PL/SQL :: How To Make PK Not To Validate
Nov 21, 2011i am writing a script for inserting rows in a table where primary key of that table consists of 4 columns. I want to add a new row where 3 columns of that table will be same but change the value of the last one. this is giving an error saying that i am violating the unique constraint. I tried to disable that constraint/PK by following statement but still this error is coming
alter table sections_budgets modify primary key disable cascade;
OR
alter table sections_budgets modify constraints sec_bdgt_pk disable cascade;
the insert statement which i am using. The first four columns are part of PK
insert into sections_budgets (SELECT sb.bdgt_cd, sb.bdgt_dpf_cd, sb.bdgt_yr, :sec_code, sb.usf_usr_id,
sb.aty, sb.comaty, sb.comytd, sb.expn_ytd, sb.sys_dt, sb.cat,
sb.start_aty, sb.expn_lmt
FROM sections_budgets sb
WHERE sb.bdgt_dpf_cd = :b_d_code AND sb.bdgt_yr = :year);
is there any other way of inserting records in this table without droping the whole table because it contains too many triggers and constraints?

Make Some Rows As A Read Only?
Jan 8, 2013Oracle Version 11.2.0.1
Windows
There are some tables in a schema. How can I make some rows as a read only i.e. no user can make either any update nor delete them. After searching in google, I found that trigger is one way, but since this way can be manipulated by dropping or renaming the trigger, so I am looking non-trigger way to achieve this problem. Making tablespace read only affects other users. I am not looking whole table as a read only, just couple of rows should be locked (no DML allowed) for specific time period and I after specific time/date this restriction should auto disable or on user call i.e. something like row's block level locking..
PL/SQL :: Way To Make A Cursor Of Record ID
Nov 15, 2012I need to run a query that runs a stored procedure. The stored procedure takes a cursor of record ids as a parameter. I've been making the cursor like this, if there was a smarter way. I can't change the stored procedure, so this is the only thing I have control over.

How To Make A Command Loop Three Times
Jun 28, 2013I have code that creates a sequence and a select statement that generates the next number in a sequence. It starts the sequence at 5 and every subsequent number is the previous number minus 3. The minimum value it can go to is 0. All I want is for my select statement to execute three times in a row. Is there any way I can do that?
create sequence MY_FIRST_SEQ
increment by -3
maxvalue 5
start with 5
minvalue 0
nocycle;
select MY_FIRST_SEQ.NEXTVAL from dual;
