i am trying to left join a selection of two or more tables. what i have found, and solved part of my problem, is that oracle left joins only the last table in the select statement ...
i.e : select * from A, B left join C on C.id = A.id wouldn't work because left join applies to B and not A.
but as my queries grow i need to make something as follows :
select * from A, B
left join C on (C.ID_A = A.ID and C.ID_B = B.ID)
[... evantually more left joins as the preceding one may go here]
this query works for DB2 but Oracle claims that "A"."ID" is an invalid identifier, while the B.ID is recognized since it's the last table stated before the "LEFT JOIN" keyword.
I tried to split the query into 2 parts , the outcome is fine but when ever i merge them ( include other table fields ) . The result is 3X3 rows .. it should be just 3 rows
The First Query ( Is running fine , 3 Rows returned )
The Second Query ( Is running fine also, 3 Rows returned )
SELECT WORKORDER.WONUM, WORKORDER.ESTSERVCOST, WP.DESCRIPTION, WP.LINECOST FROM WORKORDER , WPSERVICE WP WHERE PARENT IS NULL AND WORKORDER.WONUM = WP.WONUM AND WORKORDER.WONUM = :WO
The problem occurs when i try to merge both these queries , as the result shows 9 rows ..
I'm stuck on the CREATE VIEW part and the SELECT statement to get the output of the CREATE VIEW. We were instructed not to use AND and simply use JOIN on this exercise.
Question - For employee John Smith, give the project(s) he is working on, his department's name and the name of his division. See crows foot diagram on a separate file.
joining this query instead of using the left join. Reason is want to show the score column in a different place and also do not want to show the second IPS column that is used in the joined query.
I am working on the following SQL select and I am having a mental block on how to get it fixed. I have two tables that I need to match on the codes in each table. If there is a just one record in Table1 with the same code as one record in table2 and both the date and name match then dont output those two records. Output all records if there are more than 1 record with the same code in each table. Below is some example data that is representive of a sample in the two tables and how the output should look based on that data:
Table1 code date name aaaa 1/1/2003 billy bob bbbb 2/2/2004 louis lewis cccc 3/3/2005 joe crab dddd 4/4/2006 mary little eeee 5/5/2007 joe black
Table2 code date name aaaa 2/2/2004 larry cole aaaa 3/3/2005 nat king bbbb 2/2/2004 louis lewis cccc 3/3/2005 joe crab cccc 6/6/2008 dennis jackson dddd 7/7/2009 missy muffet dddd 5/5/2007 joe black eeee 8/8/2010 elton rocket
desired output results from select
aaaa 1/1/2003 billy bob aaaa 2/2/2004 larry cole aaaa 1/1/2003 billy bob aaaa 3/3/2005 nat king cccc 3/3/2005 joe crab cccc 3/3/2005 joe crab cccc 3/3/2005 joe crab cccc 6/6/2008 dennis jackson dddd 4/4/2006 mary little dddd 7/7/2009 missy muffet dddd 4/4/2006 mary little dddd 7/7/2009 missy muffet eeee 5/5/2007 joe black eeee 8/8/2010 elton rocket
Here is the select that I have so far:
select table1.rowid, table1_code, table1_date, table1_name, table2.rowid, table2_code, table2_date, table2_name from table1, table2 where table1_code= table2_code order by table1_code;
The above select gives me all records just fine, but does not eliminate single records that match. I tried using the Count(table1_code) > 1 and table2 code but I get a message about inproper grouping.
I have had a google around and can't seem to find an answer as to how do do the following Select statement. i am wanting to Select the following fields from across multiple tables.
i have two tables test1 and test2. i want to update the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE v_mydept1 TEST1.DEPT_CD%TYPE; v_mydept2 TEST2.DEPT_CD%TYPE; CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR; [code].......
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF" I am not sure what is the exact problem when we want to update multiple columns of different tables.
can we link a table that contains a foreign key with a sequence table? i have a table that has a sequence bookid and i want to link this table to another table that contains a foreign key of bookid.can i link this two table and how?
I have a table (promo_custom) with following colimns (id, id_promo, button_promo, button_submit, css, user, date) and other table (promo_buttons) with following columns (id, id_design, name, url, username, date) .
Columns promo_custom.button_promo and promo_custom.button_submit are foreign keys (references promo_buttons.id).
I want to create a view showing table promo_custom but instead of columns button_promo and button_submit I would like to show the column url of them.
I have two tables. The first contains all Segment information within Oracle i.e;
Table 1 Segment Description Flex_Value 1 North 1234 1 South 1235 1 East 1236 2 Car C001 2 Boat B001
and the second table contains financial data, but only the segment code;
Table 2 Date Segment1 Segment2 Value 01/01/11 1234 C001 10,000 02/01/11 1235 C001 10,000
what I want to return is some of the columns within table two as well as additional columns for the segment descriptions.
Below is an extract of what I have put together, and it does return what I need, but I'm sure there is a much more efficient way of creating the query;
We have two tables tab1 and tab2 same structures and empid and id are keys.
We need to query for records that doesnt exist in tab2 and exist in tab1 based on keys above and then insert into t2.And also we have a date column in tab1...
if we have two records..that match empid and id and if dates are different we have to take one record with the least date like min(Date) and insert that one record in to tab2.
I have a table called test_renames that has two columns(new_name and old_name) and one row with the following values
NEW_NAME OLD_NAME DRUG10 DRUG1
I have another table called SH0 that has 10,000 rows and the column of interest is called ITEM1. ITEM 1 contains the following distinct drug names:
DRUG1,DRUG2,DRUG3,DRUG4,DRUG5
Each DRUG has multiple rows associated with it.
I need to only update rows for DRUG1 and set the name from DRUG1 to DRUG10 for all rows where ITEM1 is DRUG1.
However I need to write this update statement by joining with the values in the test_renames table that contains the NEW_NAME and the OLD_NAME.
DRUG1 has 2,000 rows associated with it. The following SQL statement gives me 2,000 rows
(SELECT NVL(CHG.NEW_NAME, SH.ITEM1) FROM test_renames CHG,sh0 sh WHERE UPPER(SH.ITEM1) = UPPER(CHG.OLD_NAME) AND UPPER(SH.ITEM1) IN (SELECT UPPER(OLD_NAME) from test_renames))
However when I run the following update statement, it appears that the SQL query updates all the 10,000 rows in the table instead of just touching the 2,000 rows for DRUG1. It does change all the rows for DRUG1 to DRUG10, but all the other ITEM1 values become null. What I need from the update statement is only chnage the rows for DRUG1 to DRUG10 and leave the other rows that I associated with DRUG2, DRUG3 etc. Here is my update statement.
UPDATE SH0 SH SET ITEM1 = (SELECT NVL(CHG.NEW_NAME, SH.ITEM1) FROM test_renames CHG WHERE UPPER(SH.ITEM1) = UPPER(CHG.OLD_NAME) AND UPPER(SH.ITEM1) IN (SELECT UPPER(OLD_NAME) from test_renames))
This update statement touches all 10,000 rows. I am looking to update only the relevant 2,000 rows for DRUG1.
WITH table1 AS ( SELECT 345 id, To_Date('1/31/2010', 'mm/dd/yyyy') dt, 123 cid, 'test' txt FROM dual UNION ALL SELECT 345 id, To_Date('2/1/2010', 'mm/dd/yyyy') dt, 121 cid, 'test2' txt FROM dual UNION ALL SELECT 345 id, To_Date('2/2/2010', 'mm/dd/yyyy') dt, 112 cid, 'test3' txt FROM dual UNION ALL SELECT 345 id, To_Date('2/3/2010', 'mm/dd/yyyy') dt, 162 cid, 'test4' txt FROM dual UNION ALL
as you can see, i want to join both tables (table1 and ov_dates) and take dt from ov_dates table look it up in table1 and thengrap ov_dt and looking up in table1 and copy values of one row to the other.
for example, in ov_dates i have 3/31 dt and 4/7 ov dt. i will look for 3/31 and 4/7 row in table 1 and copy columns values from 4/7 to 3/31you can see that cid for 3/31 stay the same (since i dont want to replace the value) but txt value was replace with value from 4/7
another examplein ov_dates we have 1/31 dt and 2/5. so i go into table1 get 1/31 and 2/5 row and copy values from 2/5 into 1/31/ as you can see the txt column value for 1/31 becametest6 since it was taking from 2/5. the same thing for the rest ofdata
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.
CREATE OR REPLACE TYPE CourseList AS TABLE OF VARCHAR2(64); CREATE TABLE department ( courses CourseList) NESTED TABLE courses STORE AS courses_tab; INSERT INTO department (courses)VALUES (CourseList('1','2','3'));
[code]....
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.
I was making some variations of this code :
select d1.courses c_1, d2.courses c_2 from department d1,department d2 where d1.courses<>d2.courses(+);
I'm trying to do a sum over 2 different tables but can't get it to work...This is the idea:I have a table A with client ID, time-id (per day), purchase amount and segment code.
In another table (let call it B) I have a lot of client ID's and also their purchase amount, time-id and segment code. I want to sum the purchase amount for every client from table A and B for clients with certain segment code from table B.
This is what I have now:
select client_id, purchase_amountA+ purchase_amountB from tableA, tableB where A.client_id = B.client_id and time_id between 20090101 and 20091001 and B.segment_code = 'A'
This does the job, but it selects only client_id's which are in both tables. I want to select all client_id from table B with segment_code 'A' and add the purchase_amount from table A to their purchase amount from table B, at least, if they have any purchase amount in table A.
Each customer has a video card , When Customer rent a CD , Shopkeeper register an issue date and a Return Date . If customer return CD after Return Date Then There will be a fine of 2 Dollor .
After every 6 Months The shop Keeper review each customer Account , and Send Gifts to those customer whose Total Amount is More than 50 Dollar .and also send letters to those whose Fines Are More than 20 Dollor .
Now I am unable to understand that how many table i need to create for this .
What i have created so far is given below ,
When Customer Rent a CD then Shopkeeper will submit Following Information .
Customer_id 101 Issue DateDATE Expected_return_dateDATE Original_return_date- Fine - Total_Amount -
And at the time of return , he will Put these information .
Customer_id 101 Issue DateDATE Expected_return_dateDATE Original_return_date DATE Fine 2 Total_Amount5
But Do i need to create another table for each customer also ? That will store customer total amount , total Fines ,and shopkeeper will view it after every six months. Which type oo table i need to create ?
I need to calculate a list of people, who got some services more that 2 times with the same service koda (pas_kodas) to the same person (zmo_kodas). It should not depend on report number.
[URL]...
What I get is in green (services are calculated more than 2 times BUT in the same report).
What I need is in red: calculate servises more that 2 times ACCROSS all reports to the same person (zmo_kodas).
[URL]...
One person (zmo_kodas) can have a lot of reports (ats_nr).
Every report can have one or more services (pas_kodas).
I have a primary table and some secondary tables. I need to use the key from Primary table and get the sum/totals from the other tables with a single query.
For example, I have 3 tables employee, employeesal and employeerewards in which employee is the primary table. I need to get the total salary for an employee from employeesal table and total rewards from the employeerewards table using one query.
I am pasting the test data below:
create table employee (eno number(9), ename varchar2(40)); insert into employee values(1,'Jack'); insert into employee values(2,'Jim');
[Code]....
I am looking for a better way of doing this in terms of performance. In my projecct, those 3 tables are very big tables and I doubt if I do two inner queries and then use a outer query may not be the best way to do it.
Is there any better way to write this query in terms of performance?
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

I need to set up a trigger to check and enforce that the age of an employee at hire date is older than 18 when a new record is inserted. The age is on the PERSON table, and the hire date is on the EMPLOYEE table.
My attempt:
CREATE TRIGGER AGE_HIRE BEFORE INSERT OR UPDATE ON EMPLOYEE FOR EACH ROW BEGIN IF FLOOR EXTRACT (YEAR FROM (PERSON.BIRTHDATE - EMPLOYEE.HIREDATE)) > 18 THEN DROP NEW ELSE INSERT NEW FROM PERSON, EMPLOYEE END;
I have more 100 partition in a table, I would like to query 10 partitions alone in single statement, Hope it could be possible like query data for single partitions, provide the syntax for the same.
Because if I try to query for all the partition then the query is Hanging due to the large no of data, then I can query single partition by partition then it takes more than a day. so, I would like query data for 10 partition in a single select.
----- SELECT SUM(s1.PRODUCT_QTY) INTO anz FROM EXACTS_TRANSACTION_HAS_PDTS s1, EXACTS_TRANSACTIONS s2, EXACTS_PRODUCTS s3 WHERE s1.SALES_ORDER_ID = s2.SALES_ORDER_ID AND s2.REGION = 'ANZ' AND s1.GCM_OPP_ID = s2.GCM_OPP_ID
[Code]..
The statement sums up all the products attributed to the region ANZ and stores it in a NUMBER variable called anz.
The issue is that I have multiple regions: ANZ, JP, ASEAN etc. Wat I would do is to create a statement for each and every region. Is there a way to consolidate them all into a single statement. that means something like
----- SELECT SUM(s1.PRODUCT_QTY),SUM(s1.PRODUCT_QTY),SUM(s1.PRODUCT_QTY) INTO anz, jp, asean FROM EXACTS_TRANSACTION_HAS_PDTS s1, EXACTS_TRANSACTIONS s2, EXACTS_PRODUCTS s3 WHERE .................. -----
When I use the below code in my perl script (it is oracle database):
$query = "select a.sub_id, b.name from subscribertable a, invitationBin b where a.subscriberid=b.subscriberid"; $sth = $dbh->prepare($sub_query) or die "SELECT-Query failed";
everything is ok... and when I try to add a third table...
$query = "select a.sub_id, b.name, c.phone from subscribertable a, invitationBin b, personalDet c where a.subscriberid=b.subscriberid and b.subIdx=c.subIdx"; $sth = $dbh->prepare($sub_query) or die "SELECT-Query failed";
this fails... it seems like it doesnt let me add 3 tables in the SELECT query through perl script. The strange is that when I test this query with Oracle SQL Developer, it works fine...!
