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.
select col1, col2, col3, col4 from tab1, tab2, tab3 where conditions union
[Code]...
Now, the col4 is a date column and I have to order by the entire result sets on it. I know I can do it by (order by col4) or by (order by 4) at the end of the entire query.
But the problem is that, the output is coming in dd-Mon-yyyy (i.e 31-Nov-2012).
I want every output in dd/mm/yyyy format so I need to use to_char function.
But in that case, I cant use the order by clause, because in that case it is getting arranged by character i.e by 1,2,3,4,5 like this.
Updated to Add: In a last ditch search, I found my answer with ROWNUM <= 1 in the Where clause. It works and I can go from there with what I want to do.
I have a website that pulls similar information from multiple queries using a Union-based query. I want to only pull 1 record from one section, two from another, and 5 from the third. I've so far found LIMIT but haven't been able to get it to work in that way. Is it possible to limit each query in the union as I am looking to do?
The query is:
SELECTc.priority, c.startDate, p.headline, p.newsID, p.kicker, p.webPath, p.makePopup, p.thumbnail, p.shortDesc, p.storyType, d.filePath FROM (so_news p LEFT OUTER JOIN so_news_deptLevel c ON p.newsID = c.newsID) LEFT OUTER JOIN so_departments d ON d.deptID = c.deptID WHERE p.storyType = 'alert' AND c.display = 'yes' AND c.startDate <= sysDate AND c.endDate >= sysDate UNION All SELECTc.priority, c.startDate, p.headline, p.newsID, p.kicker, p.webPath, p.makePopup, p.thumbnail, p.shortDesc, p.storyType, d.filePath
Is there a way to avoid multiple UNION statements and get statitc values in single SQL?
select 'Week1' as term from dual UNION select 'Week2' as term from dual UNION .... ....Some functionality like selecting from dynamic table column-rows.... like .. "select term from table(term(rowvalues('Week1', 'Week2'...'Week5')) from dual" or something like that
select * from nrc_trans_descr where type_id_nrc=60013 -- it has 18 columns and i have hard coded 60013 for simplification here.60013 is derived from 3 other table Output is ( it can have many rows too.typically for each type_id_nrc there is one row ).
TYPE_ID_NRC TRIGGER_STATUS INSTALLMENT_TYPE_ID_NRC --------------------------------------------------------------------- 60013 0 61013 i have to pass TYPE_ID_NRC and INSTALLMENT_TYPE_ID_NRC to restriction_id column in a different table. currently i am doing like this select * FROM DISCOUNT_RESTRICTIONS WHERE discount_id in (12085,12086) and (restricted_id in ( select type_id_nrc from nrc_trans_descr where type_id_nrc=60013) or restricted_id in ( select installment_type_id_nrc from nrc_trans_descr where type_id_nrc=60013));
am using ORACLE 10GR2(solution for 11gr2 is welcome too)
I have a function that returns the total sum of an account. From reports I call the function passing the account code. The function sums the values for that specific account code and returns the value. In my function I have the following code :
where account_code = P_CODE.
Eg. The value of :P_CODE is 'CS'.
I now want to pass multiple account codes ('CS','TV',LJ') to the function. How do I change the IN clause in the function to accommodate multiple values.
I have tried using the instr function, but it does not work. eg. AND instr(o.ACCOUNT_CODES,','||P_CODE||',') > 0
I have a query regarding nested tables while exporting. Are we not allowed to use Query clause during the export of nested table?
I am getting the error: "EXP-00053: unable to execute QUERY on table NT_LP_COREBAL_MAINT because the table has inner nested tables Export terminated successfully with warnings."
The exp command we are using is: exp XXXX/XXXX@XXXX file=test1.dmp log=test1.log tables=nt_lp_corebal_maint query='where domain_id=10110307'.
I am trying to use model clause to get comma separate single row for multiple rows. My scenario is like this:
SQL> desc test1 Name Null? Type ----------------------------------------------------- -------- ------------------------------------ ID NUMBER VALUE CHAR(6)
SQL> select * from test1 order by id;
ID VALUE ---------- ------ 1 Value1 2 Value2 3 Value3 4 Value4 5 Value4 6 7 value5 8
The query that I have is: SQL> with t as 2 ( select distinct substr(value,2) value 3 from test1 4 model 5 ignore nav 6 dimension by (id) 7 measures (cast(value as varchar2(100)) value) 8 rules 9 ( value[any] order by id = value[cv()-1] || ',' || value[cv()] 10 ) 11 ) 12 select max(value) oneline 13 from t;
I am trying to create a simple parametised procedure when all I am doing is dynamically inserting data from a set of tables and cols on a where clause.
And for the result set I am also inserting these input variables for future ref.
---------------------------------- CREATE OR REPLACE PROCEDURE DATA_TEST (IN_TABLE_NAME IN VARCHAR2, IN_ATTRIBUTE IN VARCHAR2 ) iS FirstClause VARCHAR2(3000) := 'INSERT INTO ABC ( COL1, COL2, COL3,COL4,COL5, COL6) '; selectClause VARCHAR2(3000) :=
[Code]...
Now, the problem is that the proc is not compiling, because of that escape character.
Is there anything wrong that I am doing or some other settings needs to be done?
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 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 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.
