Query:
select sum(2) from employees
How easy it is to tell the answer without running it in SQL Developer or SQL* Plus
I am finding it a bit hard to understand the logic behind allowing Lower(2.3) and Upper(69) etc queries
I have a dynamic query stored in a function that returns a customized SQL statement depending on the environment it is running in. I would like to create a Materialized View that uses this dynamic query.
View 1 Replies View RelatedI have a table structure with test data.
desc tbl_female
Name Null Type
------------------- ---------- -----------------
ANI NOT NULL VARCHAR2(12)
CHAT_ID VARCHAR2(25)
AGE VARCHAR2(5)
RECORD_FILE VARCHAR2(25)
SUB_DATE_TIME DATE
STATUS VARCHAR2(15)
LOGIN_STATUS VARCHAR2(15)
CIRCLE_NAME VARCHAR2(10)
INTEREST VARCHAR2(10)
HOBBIES VARCHAR2(10)
OLD_ID VARCHAR2(25)
SORTED NUMBER
FAIL NUMBER
TIME NUMBER
FLAG NUMBER
POINT NUMBER
SF NUMBER
ACTIVE NUMBER
and Query depending on this table sometimes provide a row or sometimes not. Query is as follows which we are using
SELECT ANI INTO SUBANI FROM (SELECT ANI FROM TBL_FEMALE WHERE point=(select max(point) from tbl_female where circle_name in('pb','hr','hp','jk','pb','bir','dl','mp','mum','mh','gj') and sf=0 and login_status='LOGIN' and status in ('A','B') ) and circle_name in('pb','hr','hp','jk','pb','bir','dl','mum','mh') and sf=0 and login_status='LOGIN' and status in ('A','B') ORDER BY RANDOM.RAND_MAX(20)) WHERE ROWNUM = 1;
can I rewrite the following query without using the 'ROW_NUMBER() OVER ' part.The query is supposed to pull out the records whose CODE is not NULL and has most recent date for UPDATE_DATE . The reason I wanted to do this is, When I embed this query in between many other queries along with JOINs, My oracle server is unable to execute. So, I thought its better to supplant 'ROW_NUMBER() OVER ' logic with something else and try it. .
CURRENT QUERY:
SELECT a.* FROM
(SELECT b.*, ROW_NUMBER() OVER (PARTITION BY b.PIDM
ORDER BY b.UPDATE_DATE DESC) AS Rno
FROM
(
SELECT *
FROM SHYNCRO WHERE CODE IS NOT NULL
)b
)a
WHERE a.Rno = 1
I have a table structure like :-
Create table test(A varchar2(50),B NUMBER);
The data in that table is like that:-
A B
----------------------
2*3
2*4*5
4*5
column B contain no data.
I want to create a function which can be used in a select query,and the output should come like that :-
A B
----------------------
2*3 6
2*4*5 40
4*5 20
Means column B contains the resultant value of column A.And the above output should come through a select statement.You can use any function inside the select statement.
Is it possible to make query with analytic function or somehow to represent output data for next example (sql: ???):
Table: Order
sql: select * from order
Sql output>
Item Barcode Qty
---- ------- ---
1 100100 2
2 100200 1
3 100300 3
Table: Order
sql: ???
Sql output>
Item Barcode Qty ElementarQty
---- ------- --- ---
1 100100 2 1
1 100100 2 1
2 100200 1 1

I am using oracle 11G database,I have to check length of name column value from employee table and if length(name) > 39 then value should be substr(name,0,39) else value should be name only. i tried below code
select CASE when length(name) > 39,substr(name,0,39)
else name
END
from employee but its not working ..can I do this using decode too ? ,,which one would be better or this is not a right way ?

How do I do that using PL/SQL and without Cursor.
I am interested if there maybe exists any function that would return all source tables that are present in the given sql. For example function('select 'abc' from table_1, table2') would return a list containing 'table_1' and 'table_2'.

One of our query is not using function based index, the required priv is granted to the user executing the query and also tables stats are gathered? what could be the reason for the query to not to pick the FBIndx? the table is a huge one having million of records, is it that CBO thinks that not picking FB indx is the best execution plan? let me know how can we make the query use the FB indx, also there is a restriction that we cannot force it using hints.

I have a query that uses a function to find the business days between two dates.It sums the total number of days between two dates per employee to find the total days for the past 30, 90, or 365 days.
The problem is that the query takes 21 second to return the last 30 days.Over 70 second to return the last 90 days and over 140 second to return the last 365 days.Do you know how I could tune the query to return faster? Below is the query for the last 30 days:
select dwt_emp_id, SUM((SELECT GET_BDAYS(DWT_DATE,DWT_CREATE_DATE) FROM DUAL))
from dwt_dvt_work_time where dwt_create_date > sysdate - 30
and dwt_hours > 4 and dwt_usr_uid_created_by <> -1 group by dwt_emp_id order by dwt_emp_id

I'm attempting to use dynamic SQL to execute a function that returns a user-defined collection. The problem is that I don't know how to use dynamic SQL to handle user-defined types...or if this is even possible?
The code I have is as follows:
CREATE OR REPLACE PACKAGE qi_test IS
TYPE typ_qi_data IS RECORD(
iQIFlag NUMBER(1),
iIPFlag NUMBER(1),
iRiskIndicator NUMBER(1),
iDenominator NUMBER(8),
iNumerator NUMBER(8)
[code]........
I want to be able to execute the above function using dynamic SQL. Initially tried:
DECLARE
f2_data qi_test.typ_qi_data_tab;
BEGIN
EXECUTE IMMEDIATE 'begin :1 := qi_test.get_f2_data; end;'
USING OUT f2_data;
[code]......
...but this just produces "PLS-00457: expressions have to be of SQL types". So it looks like I can't do it this way if the returned data type is user defined. I know it would be easier in this instance to just use something like:
f2_data := qi_test.get_f2_data;
...rather than EXECUTE IMMEDIATE, but it's the principle that I need to get right as it forms part of a much bigger piece of work.
I have 2 tables, ASSIGNMENT and RESEARCH_PAPER. For each research paper, I need to find out :
1. The number of assignments created from it (after a given constant assign date)
2. The number of assignments created from it that have been approved.
3. The number of unique users who have either created or approved an assignment from it
Test data :
create table research_paper (id int, name varchar2(100));
create table assignment (id int, r_paper_id int, assigner_id int, assignee_id int,
approver_id int, assign_date timestamp, approved_yn varchar2(10));
insert into research_paper values (1, 'A');
insert into research_paper values (2, 'B');
[code]....
Assignment :
id r_paper_id assigner_id assignee_id approver_id assign_date approved_yn
-----------------------------------------------------------------------------------------------------------

Expected result :

I wrote the following query for that :
SELECT rp.id r_paper_id,
COUNT(*) created,

But it fails, saying that 'single-row subquery returns more than one row' when I introduce the 'unique_users' clause. The remaining fields of the output are correct.

I have inherited a query that union alls 2 select statements, I added a further field to one of the select statements ( a date field). However I need to add another dummy field to the 2nd select statement so the union query marries up I have tried to do this by simply adding a
select
'date_on'
to add a field called date on populated by 'date_on' (the name of the column in the first query)
however when I run the union query i get the error Ora-01790 expression must have same datatype as corresponding expression.
I have data in a table and another in XML file,I used SQL query to retrive the data placed on the table, and link this query with XML query that retrieves the data stored in the xml file. The data stored in the table and xml file sharing a key field, but the xml contents are less than what in the table.I want to show only the data shared between the two queries, how can I do that?
e.g.:
Table emp:
e_id | e_name | e_sal
023 | John | 6000
143 | Tom | 9000
876 | Chi | 4000
987 | Alen | 7800
XML File
<e_id>
143
876
So, I want the output to be:
e_id | e_name | e_sal | e_fee
143 | Tom | 9000 | 300
876 | Chi | 4000 | 100
I am looking to simplify the below query,
DELETE FROM A WHERE A1 IN (SELECT ID FROM B WHERE BID=0) OR A2 IN (SELECT ID FROM B WHERE BID=0)
Since both the inner queries are same,I want to extract out to a local variable and then use it.
Say,
Array var = SELECT ID FROM B WHERE BID=0;
And then ,
DELETE FROM A WHERE A1 IN (var) OR A2 IN (var)
How to do this using SQLPLUS?
