SQL & PL/SQL :: Query Without Outer Join
Nov 2, 2012I have an attendance table in which we have empno, time_in, time_out..etc.
I want to create a matrix report that should shows all dates of any specific required month in columns and present empno in rows and time_in in cells.
I did it with using a temporary table by filling all the required dates and outer join with attendance table, it works fine, but it takes so long, is there any other better fast way to do it?

View 4 Replies View RelatedAlias In Inner Join Query
Feb 27, 2008In my Oracle 9i Schema, I have two tables:
Table One
pocOne pocTwo
2 3
2 4
1 2
Table Two
TableTwoId Name
1 Jones

My SQL to fetch all records with Smith works great:
select Name from TableTwo
Inner Join TableOne
on TableTwo.TableTwoId in (TableOne.pocOne, TableOne.pocTwo)
where Name = 'Smith'
Now I need to create an alias for the Name field. Here is my attempt:
select myAliasName from TableTwo
Inner Join TableOne
on TableTwo.TableTwoId in (TableOne.pocOne, TableOne.pocTwo),
(select Name as myAliasName from TableTwo)
where myAliasName = 'Smith'
This attempt pulls up all the records instead of just Smith records. How I can create an alias for the Name field in my above query?

PL/SQL :: Update Statement In Join Query
Nov 16, 2012I've seen this example numerous places, and tried to implement it, but I keep getting an "invalid identifier" error message, despite the fact that I've got the table and column specifically identified.For instance, my query reads like:
UPDATE tbl1
SET tbl1.EMPID =
(SELECT tbl2.EMPIDA FROM tbl2
WHERE LOWER(tbl1.EMAILCOL) = LOWER(tbl2.EMAILCOL2)
)
WHERE tbl2.EMPIDA IN ('Z1O435','S8M4722','M0D5156')
AND EXISTS
(SELECT tbl2.EMPIDA
FROM tbl2
WHERE tbl1.EMAILCOL= tbl2.EMAILCOL2 );
But I'll keep getting flagged at the tbl2.EMPIDA column reference. I have not tried this in SQL Plus, just in TOAD, but it seems to repeatedly fail.I have had to dump records to standalone Access tables and link back to perform the updates.

Optimizer Behavior With Hierarchical Query And A Join?
Jul 23, 2013The full statement is:
SELECT v.key$ FROM VERSION_TABLE v, DOCUMENT_TABLE d, CLASS_TABLE z WHERE
v.documentKey = d.key$ AND
d.classKey = z.key$ AND
z.key$ IN (SELECT zz.key$ FROM CLASS_TABLE zz
START WITH zz.name = 'esDTTemplate'
CONNECT BY PRIOR zz.key$ = zz.parentKey) AND
v.ESGROUP = 'SearchOperatorsMapping' ORDER BY d.name
Now I noticed that the subquery is never used to seed the join: indexes - if any - are used. Otherwise a full table scan is performed.In the example - if ESGROUP is indexed, then it's chosen to start the join evaluation. If not, a full table scan is performed.Is there any way to suggest to the optimizer to use the subquery in case there are no indexes - as a fallback ?
In the above example where VERSION_TABLE contains nearly two million records, the no index solution takes 60 secs. vs. less than 1 sec. in the index case.Wrapping the hierarchical query in a inline view leads to same result.
PS: the execution plan (without index) is:
-------------------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time
-------------------------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | | | 9 (100)| |
| 1 | SORT ORDER BY | | 1 | 171 | 9 (23)| 00:00:01 |
|* 2 | HASH JOIN SEMI | | 1 | 171 | 8 (13)| 00:00:01 |

Query Optimization On Join With A View On Huge Table?
Jun 22, 2011I have this table
create table ACTIONARI_ARH
(
actionar_id NUMBER(10) not null,
id VARCHAR2(20) not null,
id_2 VARCHAR2(20),
tip VARCHAR2(1),
nume VARCHAR2(100),
prenume VARCHAR2(100),
adresa VARCHAR2(200),
[code]....
and this view
CREATE OR REPLACE VIEW ACTIONARI AS
SELECT "ACTIONAR_ID","ID","ID_2","TIP","NUME","PRENUME","ADRESA","LOCALITATE","JUDET","TARA","CERT_DECES","DATA_REGISTRU" Data_operare,"USER_MODIF","DATA_MODIF","REZIDENT"
FROM (
select
[code]....
The table has about 30 milion records and holds persons names, addresses, personal id (id), and internal id(actionar_id) and date when a new adress has been added.
The view is about getting only the most recent info for one person (actionar_id).
if i run a
a) select * from actionari a where a.actionar_id = 'nnnnnnn', result is returned immediatly, oracle uses index and does not do a full table scan.
b) select * from actionari a where a.actionar_id in ('nnnnnnn','mmmmmm','ooooooo'), result is returned immediatly, oracle uses index and does not do a full table scan.
my problem when i use this view in a join.let's assume i have another table with no more than 500 records, something like
create table SMALL_TABLE
(
actionar_id NUMBER(10) not null,
......
);
and if i run
select *
from SMALL_TABLE s
join actionari a
on a.actionar_id = s.actionar_id;
it takes like forever to process, forever means 1~3 minutes.by looking at the execution plan, oracle does a full table scan, creates the view for all unique 7milion persons, and only then joins the result with the actionar_is's in the small table and returns the desired 500 record result.i am using oracle 10g.
SQL & PL/SQL :: Cross Join Query To Remove Repeating Combination
Nov 15, 2010I have constructed a cross join query, with the test case below
create table ajit_sites (
site_id char(1));
insert into ajit_sites values ('A');
insert into ajit_sites values ('B');
insert into ajit_sites values ('C');
COMMIT;
sql below is constructed to display combination of all sites (cross-join), it also removes records where "origin" is the same with "dest"
select
a.site_id origin, b.site_id dest
from
(select site_id from ajit_sites) a,
(select site_id from ajit_sites) b
where
a.site_id <> b.site_id b
Is there any way i could remove records with the behavior below
Origin , Dest
A , B
B , A
For instance from the example above, i want to only retain one of the records since record (A, B) or record (B, A) means the same.
