Help me in writing this query plz....
There are two tables - Table1 (table1_id, value1) and Table2 (table2_id,
table1_id, value2). The field Table2.table1_id is a foreign key to
Table1.table1_id. It is necessary to write a SQL query that would find
all records in Table1 that do not have a corresponding record in Table2.
The query should not use sub-selects

Try and work it out for yourself; if you get stuck, we'll try and help from that point, but you'd have to provide the sql queries you've tried (along with table information and sample input and expected output data).

Help with re-writing this query
Dear experts;
create table t2

insert into mappingt2 values ('C', 'Linda');
insert into mappingt2 values ('B', 'CC');I have the following query below
SELECT (select grades from mappingt2 t
where t.individual = pt.ID) as current_grade
,(select grades from mappingt2 ty

Hi Frank, Tom Kyte claims sub scalar queries is usually betterHe didn't say usually he said if you want the first row faster

if your goal is to optimize your query for initial response time, you may want to use the former query, with the scalar subquery, because Oracle Database would have to get just the first row from DEPT, run the scalar subquery (select count...) against EMP to get the count, and then return it. The process for returning that first row would be very fast.

The corollary to this that was not explicitly mentioned in the article that I can see is that this probably comes at the expense of the time taken to return all the rows which can then take longer. -

Hi all,
How to do a token match of a string with the token of another mathc
EX:
LET THE FIRST STRINGS WITH A COMMA separated like below
"firsttoken,second,third,are,the,parts,of,a,string"
LET THE SECOND STRING WITH A COMMA separated like below
"this,is,the,search,tokens"
Now I have to match any token of the SECOND string with any TOKEN OF THE FIRST string
If atleast one match is exist then its treated as success..
I need only sql, not pl/sql
Preferrable if analytical functions not used.
Thanks in advance,
KhaleelKhaleel,
I understand the limitation to use PL/SQL. I have similar kind of limitations at my end, I am not allowed
to leave any custom procedure/function definitions in the db with out taking the permissions for them.
Here is the SQL solution for you for variable number of TOKENS. Only requirement is UPPER BOUND
should be known. You could have variable number of tokens in either of the strings as long as you code it for the maximum number of tokens in each string. Here I coded it for 4 tokens in each string, hence I could use any number of tokens <= 4 in each string. Couple of tests here, -- Strings with different number of tokens but with a matching word

YES_NO
MATCH NOT FOUNDLooks cumbersome, but works. You should be able to take it from here to extend the functionality also,
like if you want to know which words are matching OR which words are not matching etc.., you should be
able to tweak the SQL accordingly.
Good luck,

Following is the structure of my table.
Data
Key Number
Id Number
Value varchar2(100)
activity_name varchar2(100)
Creation_Date Date
Eval_Point varchar2(100)
In the above table Id is the primary key.
The column eval_point holds only two types of entries 'activation' or 'completion'
The activity_name column holds the name of the activity.
The sample entries in the table are as follows
Key Value activity_name Creation_Date Id Eval_Point
260002 XXX assign_1 2007-09-21 16:58:41.920000 951 activation

260002 XXX assign_3 2007-09-21 16:59:24.421000 957 completion
i need to write a query which gives me data in the following format

XXX YYY 2007-09-21 16:58:41.920000 2007-09-21 16:58:43.392000
where start_date is the creation date of the 'activation' and end_date is the creation_date of 'completion'.
Can somebody help?

Please can you help me in Tuning this query..?
Hi ,
Please can you help me in re-structuring this query? .Details are given below.
I have 2 tables as shown below and data is like this.
Position
COD IND
AAA N
BBB N
CCC N
DDD Y
Distance
orig dest
AAA BBB
BBB CCC
AAA CCC
I need to create the records like this
start end
DDD AAA
DDD BBB
DDD CCC
The query which i am using now for this is
select p.code AS start,
P1.CODE AS end
from position p, position p1
where
P.CODE != P1.CODE
AND (P.ind = 'Y' or P1.IND = 'Y')
AND not exists
(select 1
from distance d
where (d.orig = p.code or d.dest = p.code)
and (d.orig = p1.code or d.dest = p1.code))
table is having above a crore record. so its taking a lot of time.
Please someone please help in tuning this query?
Thanks and regards,
ShabirLooks like you want this
select a.strt, b.ends from
(select p.code strt from position p where p.ind='Y') a,
(select p.code ends from position p where p.ind='N') b
where not exists (select 1 from distance d where d.orig=a.strt or d.dest=a.strt);
DDD AAA
DDD BBB
DDD CCCYour query result is:
AAA DDD
BBB DDD
CCC DDD
DDD AAA
DDD BBB
DDD CCCYou should be more descriptive about what kind of result you want, so that people can get more interested in helping you. -

Help in fine tuning this query
My query id this,
select a.event_id,a.document_id
from sample_transaction a
where exists (select 1 from sample_transaction b where b.event_id <> a.event_id and b.document_id = a.document_id );
The execution plan is like this,
SELECT STATEMENT Cost = 5596
FILTER
TABLE ACCESS FULL SAMPLE_TRANSACTION
TABLE ACCESS BY INDEX ROWID SAMPLE_TRANSACTION
INDEX RANGE SCAN I_SAMPLE_TRANSACTION_FK_EVT
There are 6 million records in the table.
How can i fine tune this query so that i get the results
Example is
my table has
EVENT_ID DOCUMENT_ID
100 200
100 200
101 201
102 201
103 203
104 203
105 204
105 204
106 106
My result should be
EVENT_ID DOCUMENT_ID
101 201
102 201
103 203
104 203
nullBased on your select statement, you will bring back every row in sample_transaction where the document is referenced by more than one event. Looking at it another way, the only rows skipped are those where the document is only used by one event.
The full table scan is not necessarilly a problem since Oracle has to check all rows. You may improve performance if you add an index on document_id. That will allow Oracle to do a better query on the EXISTS clause. Remember to rebuild your statistics after adding the index. -
Dear experts. help me with this query plz.
i am generating a report in dev6i.
the following query is working properly. and also fetching the data with outer(+) join.
select i.itemcode,sum(gs.approved)-sum(iss.issuedqty)
from ims_itemcode i,ims_issues iss, ims_grns gs
where i.itemcode=gs.itemcode and gs.itemcode=iss.itemcode(+) group by i.itemcode;
but i have to join two more tables (ims_issuem,ims_grnm)
after adding these two tables the query will be
select i.itemcode,sum(gs.approved)-sum(iss.issuedqty)
from ims_itemcode i,ims_issues iss, ims_grns gs, ims_issuem im, ims_grnm gm
where i.itemcode=gs.itemcode and gs.itemcode=iss.itemcode(+) and gm.grnmserial=gs.grnsserial and
im.issuemserial=iss.issuesserial group by i.itemcode;
now the query works but doesn't fetch the results with outer(+) join. it just picks the results which are matching in both the tables but i want the results along with the outer(+) join.
what is the problem in the second query please help.You need to add more outer join.
Try this..
select i.itemcode,sum(gs.approved)-sum(iss.issuedqty)
from ims_itemcode i,ims_issues iss, ims_grns gs, ims_issuem im, ims_grnm gm
where i.itemcode=gs.itemcode (+)
and gs.itemcode=iss.itemcode(+)
and gm.grnmserial(+)=gs.grnsserial
and im.issuemserial(+)=iss.issuesserial
group by i.itemcode;if not work, try a trick. After your first query work. add one table and check if need add outer join.
Hope this helps

Hi Folks,
I'm trying to write a query to retrive the following information regarding snapshots. I tried lot of ways and couldn't get the solutions so seeking your help...

snapshot name and their base table
refresh type (if it is fast, please list he snapshot log used)
refresh group which snapshot belongs to
dbms_job number which perform the refresh, job current status
refresh frequency
last refresh time
thanks
KarthikIf you tried a lot of ways ... post your work and show us what you have done.
What you are being asked to do is query data dictionary views. Do you know which ones?
SELECT view_name
FROM all_views
WHERE view_name LIKE '%<you fill this in>%';That is all the hints you get until you show your work. -
Hi need help in writing this query
A table has three columns - id (primary key), categoryID (numeric) and
amount (numeric). The goal is to provide a query that would show categoryID
and sum of amounts within that category where categoryID is an odd number
and sum of amounts is greater than 100,000select categoryid,sum(amount) from table where mod(categoryid,2)=1
group by categoryid
having sum(amount) > 100000
Regards,
Yuri
