I saw a strange plan for one query in TESTING DB today. Although 2 tables are involved i dont see any join , NL/HJ/SMJ !! i am not facing any performance issue but curious to know what type of optimization oracle is doing here.
Query text and plan :
SELECT FIRST_NAME
FROM CAMPA.TABLE_A
WHERE NAME_ID =
(SELECT NAME_ID
FROM CAMPA.TABLE_B
WHERE ban=:b1);
[code]....
Below Query I understand is improper wrt syntax. Need to modify query to fetch correct result for me.
select * from tableA order by
case when a is not null then
a DESC
else
b DESC, c DESC END
Note: DESC or ASC is dynamic coming from java-code.
I have 2 tables SEC_MASTER_HISTA and SEC_MASTER_HISTB.
Now, I need to compare the data of the two tables column-wise.
Ideally the 2 tables should have the same security_alias values but in my case they do not as the two tables belong to 2 diff client models. There is however a main SECURITY_MASTERA and SECURITY_MASTERB tables which have the security_alias recorded and a primary_asset_id column value which can act as a link between SEC_MASTER_HISTA and SEC_MASTER_HISTB. But, I have not been able to figure out the exact query which will be ideal.
Attached are the table structures and the data it contains.
Note: I need to compare the Coupon and Freq column values of SEC_MASTER_HISTA and SEC_MASTER_HISTB.
I have a temp table and want to insert that data into 2 tables. In both of my tables i have a sequence column but in my second table its a foreign key to the main table
up_query="INSERT INTO AFFILIATE (FNAME,LNAME,EMAIL,PHONE,ORG,ADDRESS1,ADDRESS2,COUNTY_ID,AFF_ID)
Select a.FNAME, a.LNAME,a.EMAIL,a.PHONE, a.ORG, a.ADDRESS1, a.ADDRESS2,C.COUNTY_ID,'AF'||aff_seq.nextval
FROM temp_aff A LEFT OUTER JOIN COUNTY C
ON UPPER(A.COUNTY)=C.CNAME";
$up_query2= "INSERT INTO TEST4 (DEPT_ID,CAMP_ID,AFF_ID, PASSWD)
SELECT D.DEPT_ID,C.CAMP_ID,aff_seq.currval,'Zq'||dbms_random.string('A',4)||'$8' from dual,TEMP_AFF A
left outer join DEPT D ON (UPPER(A.DEPT)=UPPER(D.DNAME))
left outer join CAMPUS C ON (UPPER(A.CAMPUS)=UPPER(C.CPNAME))";
However in my test4 table its inserting the aff_seq.currval for all records. Its not incrementing as in the affiliate table.
how to join 2 tables to get the result I need.I have following 2 tables (all dummy data)

I have tried writing union queries and exists clause in where and seem to get nowhere with this.
Here is what I'm trying to do:
I have three tables:
TABLE1 TABLE2 TABLE3
NCI 1AB OPEN
NCI (NULL) (NULL)
INV (NULL) (NULL)
NCI 2AB REOPEN
What I want to do is to return all of the rows from TABLE1 that are NCI regardless, and if they are NCI, I want to return the corresponding records from TABLE2 and TABLE3.
If TABLE1 has a record of NCI but there are no corresponding records in TABLE2 or TABLE3, then of course the columns for TABLE2 and 3 would be blank.
I can get all of the NCI records from TABLE1 when I LEFT JOIN with TABLE2, but when I try to specify TABLE3 in the FROM statement, only the records that are NCI in TABLE1 AND have data in TABLE2 are returned, not just all records with NCI in TABLE1.
Let me know if I can further clarify.
I know that you do not have access to my tables, but here is an example of my code so that you may understand my quandary further:
SELECT l.sku AS "SKU",
l.loc AS "LOC",
l.qty AS "QTY",
o.ncikey AS "NCI",
r.description AS "NCI DESC",
o.qtyexpected AS "NCI QTY EXP",
o.qtyreceived AS "NCI QTY REC",
o.loc AS "NCI LOC",
o.status
[Code]...
CREATE TABLE MTCH_TBL
(
S_PAID VARCHAR2(100),
S_SEC NUMBER,
H_PAID VARCHAR2(100),
H_SEC NUMBER
);
[code]....
My requirement is to match the records in MTCH_TBL and HIST_TBL on the basis of joining S_SEC(MTCH_TBL) with SEC_ALIAS(HIST_TBL) and INSTANCE (HIST_TBL) as 100 and choosing the record with max EFF_DATE from HIST_TBL.
I have come up with a query as:
select a.h_sec, a.s_paid, a.h_paid
FROM MTCH_TBL a,
HIST_TBL b
where a.S_SEC=b.sec_alias(+)
and b.instance(+)=100
and b.EFF_DATE =
[code]...
join using the EFF_DATE field also and get the expected results.My results are appearing as BLANK. However I need to produce the results as stated below:
Now, i need the results as:
H_SEC= 526
S_PAID= Q00
H_PAID = Q00
I am trying to write an Update that really frustrates me because it won't work for one reason or another.The situation is that I have two tables for customer information, t1 with the names of the customer and t2 with the address.These two can be joined via a client_id.
Now I have a third table t3 with the name and address of potential customers. I want to find out if some of them are already known to me so that I can update the client_id from table t1 or t2 into t3.
I have to join firstname, lastname from t3 to firstname, lastname from t1 and street, zip, city from t3 to street, zip, city from t2 and client_id from t1 to t2. Additional there is the problem that there can be more than one result so I have to update one of the found client_ids per name/address into t3.I am no expert to PL/SQL, I just know what SQL works in Access and that is:
UPDATE (t3 INNER JOIN t1
ON (t3.firstname= t1.firstname) AND (t3.lastname = t1.lastname)) INNER JOIN t2
ON (t3.city = t2.city) AND (t3.zip = t2.zip) AND (t3.street = t2.street) AND (t1.client_id = t2.client_id)
SET t3.client_id = t1.client_id;
I'm looking a way to easily join two tables on date value but right table has no all possible dates so I need t fill missing records with MAX(DT) values.
My tables looks like
CREATE TABLE CAL
(DT DATE NOT NULL
);
INSERT INTO CAL
(DT
[code]......
And I was trying to merge them somehow to get following result (for all missing dates from SOME_DATA I want to get value corespond to maximum data not higher than cal.dt):
-- good result
| CAL.DT | SOME_DATA.SOME_VAL |
-----------------------------------
| 01/01/2012 | 10 |
| 02/01/2012 | 10 |
| 03/01/2012 | 15 |
| 04/01/2012 | 15 |
| 05/01/2012 | 15 |
[code]......
I'm wondering what part of this query is wrong because obviously I'm not getting the desired results.
select a.iss_id,C.ISSR_ID
from ft_t_isid a left outer join ft_t_issu b on a.INSTR_ID=b.INSTR_ID
left outer join ft_t_irid c on b.INSTR_ISSR_ID=c.INSTR_ISSR_ID
and a.ISS_ID in ('CA13606ZDD20',
'CA780086AP98',
[Code]...
I know that the problem is in the joins. I expect to get 9 rows of result but I get a lot more and they are not even what I'm looking for.
I'd like to join tables in a cursor.
I tried coding this way...
CURSOR studgrade_cur IS
SELECT g.stud_id, g.grade, subj_code, s.description
FROM studgrades g JOIN subjects s
ON(g.subj_code = s.subj_code)
WHERE stud_id = :Studentprofile.student_id;
but i got an error, saying:
Quote:encountered the symbol JOIN when expecting one of the following:
,; for group having intersect minus order start union where
connect
Is it not allowed to use JOIN statement in a cursor?
I am trying to insert records in multiple tables. I know how to view data using joinig, but unable to understand how to insert records in multiple tables using Joining. I searched it on net, but didn't find much. I have also tried to write a code, but it is not working, I have seen some examples on different websites where people are using SELECT in INSERT statement for joining. What is the correct Syntax to INSERT record in Multiple tables.

I have two permanent tables. I want to add the column DELTA_STROM from the table "Delta" into the table "TEST2". Here, the value of the field "POWER_DELTA" in the table "TEST2" depends on the field "Trade_Date".
If the time of the timestamp in table "Test2" is smaller than 12:40 than the value (DELTA_STROM from DELTA) of the day must be added into the field. If the time is huger than 12:40, the value of the next day must be added into the field "POWER_DELTA". All values for "Power_DELTA" for every day are in table "Delta" in the field "DELTA_STROM".
I just added the right values of "Power_Delta" into the table "TEST2" manually to give an understanding.

I have to do the optimization of a query that has the following characteristics:
- Takes 3 hours to process
- Performs the inner join with 30 tables
- Produces an output of 280 million records with 450 fields
First of all it is not feasible to make 30 updates (one for each table) to 280 million records.
The best solution that I had found so far was to create 3 temporary tables, where each of them to do the join with 1/3 of the 30 tables, and in the end I make the join between the main table and these three tables temporary.
I know that you will ask (or maybe not) to the query and samples, but it is impossible to create 30 examples.
how to optimize this type of querys that perform the join with multiple tables and produce a large output with (too) many columns.
I have 2 tables as shown below. I have to join those tables and get data as in table 3. Condition is I have to get sum of scores for each student where category is 1 and active is Y.
Table1:
col1col2category
A 10 1
A 10 2
B 10 1
B 20 2
C 10 1
D 20 1
J 30 1
Table2:
colAcolBActive
A10Y
A20N
B30Y
B40N
Z35Y
Table3:
STUDENTSCORE
A20
B40
C10
D20
J30
Z35
query to show student name and sum of his score where category is 1 and active is Y. I am using Oracle 8i.
Trick is that I've got 4 tables
Sale , sale_details, sales_message, message_text
Table:Sales
Sales_id
Table: Sales_product
Sales_id, sales_product_id
Table: Sales_message
Sales_id, sales_message_id, message_text_id
Table:Message_text,
Message_text_id, message_text
Thing is how can I join those tables to get all the sales ID's that have at least two products one of which has got any number of messages and the other one hasn't got ANY any messages. So another words one sale entity that has both products with messages and at lease one with no message. Something like this
Sales 1 ID 123
Product1 ID 1234 for sale ID 123
Product2 ID 4321 for sale ID 123
Sales_message ID 098 for product ID 1234 'blabla'
Sales_message ID 876 for product ID 1234 'albalb'
AND NO MESSAGES FOR PRODUCT 4321
This is what I want to get from DB.
I have two tables. i need to join the tables. The query is -

As the title of this topic illustrates, i'm having trouble dumping relevant data from columns of different tables. I am using isql*plus. I have three tables appropriatly related. A 'course' table, 'student' and 'next_of_kin' tables. I have many students enrolled on various courses but only a hanfull of courses offer the module option 'Database Systems'. I have no 'module' table but i know the three course names which provide the module option. I intend on producing a report hich lists all students enrolled on the courses which provid the module option 'Database Systems'.
I have attempted the report but i keep getting a 'cartesian product' displaying all next_of_kin names instead of the appropriate. Also i am struggling to come up with the right WHERE statement to depict only the three courses which provide the module option 'Database Systems' as defined by 'courseNo' in both 'course' and 'student' tables.
Here is the most recent attempt:
--set echo off
--set pagesize 24
--set feedback off
--set linesize 78

these are the sample data :

CREATE TABLE department (
courses CourseList)

INSERT INTO department (courses)VALUES (CourseList('1','2','3'));

The query returns the correct data, CourseList that are not subset of any other CourseList of the table.
I am trying to convert this not exists in a left outer join query to check if the performance is better, but I don't know how to do it.
