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'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.
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).

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 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 have a view that contain multiple tables with ( UNION all ) clause , is there any way that if i query from this view I can explicitly specify the table that i need the data from ?
Let say i have view that contain salaries of 2011
Create view sals_2011 as select * from sals_jan2011 union all sals_feb2011 ..... union all select * from sals_dec2011.
if i issued select * from sals_2011 where emp_id >500 and date < 01-feb-2011 the explain plan show me that full tables and indexes are in processing, while i know that i need only to scan sal_jan2011, and of course it is taking much longer time than selecting from the original table only.
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've been given the task of importing an XML file into multiple tables within our database using PL / SQL and I am wondering what the best approach would be.
The files will be quite large and I need the code to be as flexible as possible.

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.
Insert into library_users, library_users_info (library_users.username, library_users.password, library_users_info.address, library_users_info.phone_no) VALUES (...)
We get data from our customers which we load into temporary tables.The goal is to consolidate this data into one single table.
Following are the rules:
1) final table should have all the columns from all the tables. If there are common column(s) then add only one column with that name.
2) the join would be based on all the common columns
3) if there is a common row, we merge the row into one (example, the row with DOMAIN = ACME.COM)
4) There could be 'N' number of tables
Following is the most realistic data.
1) T1/T2/T3 has the sample data which cover most of our test cases
2) We are expected to transform the data from T1/T2/T3 as depicted in table T4.
3) we might have more than 3 tables in our production environment, so the query should work for N tables.
4) I have given the explanation of how each row should be derived to be inserted in T4
5) the only information we have to work with is the TABLE_NAME(s) and its metadata from USER_TAB_COLUMNS
DROP TABLE T1; DROP TABLE T2; DROP TABLE T3; DROP TABLE T4;
[code].....
Explanation for each row:
row1) This row comes from T1 and T2 (not T3 because HOSTNAME would not match) row2) This row comes from T1 and T3 (not T2 because HOSTNAME would not match) row3) This row comes from T1 and T3 row4) This row comes from T2 and T3 row5) This row comes from T3
I have to write a "after update trigger". Here, i have to update the stock table by other inventory tables (by complex query). I have written trigger below. how to make it correct?
create or replace trigger trg_stk_upd_pur after update on O_STOCK_EFFECTS REFERENCING NEW AS new OLD AS old FOR EACH ROW
(I put ... because there are a lot of columns which are not interesting for this question.)
Remark: team_id and agent_id are neither primary keys nor UNIQUE.
In a third table I have a column with exactly the same data type, that is, VARCHAR2(20). What I need is to make sure that its value is at least in one of the tables TEAM or AGENT (so the only thing that is important is to check that the specified value exists no matter in which of the two tables, but just to make sure that it exists somewhere).
The solution that I have found so far, is to create a BEFORE INSERT trigger on the table. Within the trigger I create a cursor
CURSOR c IS SELECT team_id FROM TEAM UNION SELECT agent_id FROM AGENT;
I have a service that executes a pl/sql function (legacy app) to delete records from multiple tables. This function works fine in development, and has worked fine in production until about a week ago. I'm not a DB guy but the DB guys are trying to say this is an application issue. That may be, be the "insuff privileges" really leads me to believe otherwise.
What is causing this type of Oracle error? Permissions between dev and prod are the same, yet it works in dev but not prod.

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 have 8 tables and I want full outer join on these to get the output. The tables are very small having 10 rows at max and consists of only two columns (date and value).
send me the command for exporting multiple tables(1000+) in Linux env. 9i db, i know we can do using spool command but dont know exactly how to put it. i know using Datapump but this is 9i.
"Create a view named vuPassFailRate that will show the pass rate and fail rates of each test."
I have a table named Test_ID containing the following columns:
TEST_ID TEST_NAME PASSING_GRADE
And another table named Test_History containing the following columns:
TEST_ID STUDENT_ID SCORE
I'm assuming i have to create an inline view, and to work out the pass/fail rates i need to do something along the lines of (For pass rate) Where SCORE is greater than or equal to PASSING_GRADE, and TEST_ID equals TEST_ID, divide by a count of SCORE and multiply by 100. I just cant work out the nested select statements, and work out the formula using two columns in two tables.
I have been staring at this problem for so long now i cant see the wood for the trees.
