I have many different file names within my table and I want to remove the .TXT extension from each one. I want to try this SQL but being a newbie in Oracle, I don't know how to say "Left" characters. "Left" is an invalid identifier.
Update TableName
Set File_Name = Left(File_Name, Len(File_Name)-4)
Where File_Name LIKE '%.TXT'
I have already done auto increment by making sequence and trigger. but now the problem is when i am trying to retrieve data from that table it returns all data perfectly but the primary key that is my auto increment value shows blank.I am facing this problem with join query, there 4 table left joined in my query. But when I remove join from my query then it shows that value.
But i need that value in my join query.So, what is the problem and what can I do?And other thing is when I apply this query in Oracle SQL Developer, it works perfect.

I am creating a query where I am trying to take phone call lengths and put them into buckets of length ranges 0:00 - 0:59, 1:00 - 1:59 etc. Even if there are no calls in the call table I need to return the range with a zero (hence the left join and nvl). When I do this the left join acts like an equal join, I suspect there is some reason left joins only work if there is an equal condition in the join (instead of >= and < that I use, or similarly I could use BETWEEN). I also have a question about performance (below).
The create table script for the lookup is like this:
CREATE TABLE DURATION_RANGES
(
RANGE_TEXT varchar2(20),
RANGE_LBOUND decimal(22),
RANGE_UBOUND decimal(22)
)
Sample inserts are:
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('00:00 - 00:59',0,59);
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('01:00 - 01:59',60,119);
etc.
The query is:
select
r.range_text as duration_range,
nvl(count(*),0) as calls,
nvl(SUM(call_duration),0) as total_duration
from
[code]...
As I say, it is not returning all ranges in the duration_ranges table, so acting like an inner join. I realize one solution would be to populate duration ranges with every value possible (instead of ranges) so join is an equal join, but that would make the duration_range table larger.
My questions:
1. Is it possible to get the left join to work with the duration range values as they currently are?
2. Even if 1 is possible, would it be better performance to have exact values (but a larger lookup table) and do an equals join instead of >=, < or BETWEEN? Performance now is not bad.
What I mean is (with only one time value and not lbound and ubound:
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('00:00 - 00:59',0);
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('00:00 - 00:59',1);
INSERT INTO DURATION_RANGES (RANGE_TEXT,RANGE_LBOUND,RANGE_UBOUND) VALUES ('00:00 - 00:59',2);

Here's a simplified version of the query I am having problems with:
SELECT
assoc.association_id
FROM mentor_initiative mi
LEFT JOIN program assoc_prog ON assoc_prog.program_id = -1
LEFT JOIN mentor_association assoc ON assoc.mentor_initiative_id = mi.mentor_initiative_id AND
NVL(assoc_prog.program_id, -1) = NVL(assoc.program_id, -1)
Note that there is no program with program id -1. So the assoc_prog left join will come up with nothing. I was thinking that since assoc_prog.program_id will be null, the second assoc left join would pick the row where assoc.program_id is null. However, the second left join doesn't join to any row.
In this query, it does join to an assoc row (I changed assoc_prog.program_id to NULL)
SELECT
assoc.association_id
FROM mentor_initiative mi
LEFT JOIN program assoc_prog ON assoc_prog.program_id = -1
LEFT JOIN mentor_association assoc ON assoc.mentor_initiative_id = mi.mentor_initiative_id AND NVL(NULL, -1) = NVL(assoc.program_id, -1)
I was thinking it would join to an assoc row in the first query though. How can I change the first query to have the desired effect of left joining to a row where assoc.program_id is null if assoc_prog.program_id is null?
I am observing some skewed results for Left outer join where the main table has NULL in the field we are joining against with another table.
Just wondering if there are some tricks to get over it. I am currently using NVL(tab1.col1,'X') = NVL(tab2.col3,'X') and am just wondering if there is a better way to handle this.
Even though i am using COL1 CHAR(500) NULLIF COL1=BLANKS, then also i am getting same error for those columns.

I have two tables employee_master and employee_time. There could be situation that record from employee_master does not exist in employee_time.
create table employee_master(employee_id number, employee_name varchar2(100));
insert into employee_master values(1, 'employee 1');
insert into employee_master values(2, 'employee 2');
insert into employee_master values (3, 'employee 3');
create table employee_time(employee_id number, project_id number, project_type varchar2(20), time_date date, hours number)
insert into employee_time values(1, 100, 'Billable', '01-Oct-2010', 10);
insert into employee_time values(1, 200, 'Billable', '02-Oct-2010', 9);
insert into employee_time values(1, 210, 'Non Billable', '03-Oct-2010', 10);
insert into employee_time values(2, 100, 'Billable', '01-Oct-2010', 10);
insert into employee_time values(2, 200, 'Billable', '02-Oct-2010', 9);
The requirement is to show all the employees from employee_master and with total billable hours and non billable hours, if not exist, show zero.The output will be:
Employee_ID Employee_Name Total_Billable_Hours Total_Non_Billable
1 Employee1 19 10
2 Employee2 19 0
3 Employee3 0 0
The question is to write a Left outer join query or to write a PL/SQL function which can return total rows if Employee_ID is supplied to it as a parameter
Query 1:
Select Employee_ID, Employee_name, sum(Billable), sum(Non_Billable)
From
(
Select a.Employee_ID, a.employee_name,
decode(b.project_type, 'Billable', hours, 0) as Billable,
decode(b.project_type, 'Non Billable', Hours, 0) as Non_Billable
from employee_master a
left outer join employee_time b on a.Employee_ID=b.Employee_ID
)
Group by Employee_ID, Employee_Name
Query 2:
Select Employee_ID, Employee_Name, func_billable(Employee_ID) as Billable, func_non_billable(Employee_ID) as Non_Billable
From Employee_Master
Which query is good from the performance perspective? In real situation the employee_time is a very huge table.
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.

Give me the query
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 the following 2 SQLs ; one return 1 row, another one is no row returned.
select v.value
from v$parameter v
where v.name = 'cpu_count';
return value "1"
select o.value
from v$osstat o
where o.stat_name = 'NUM_CPU_CORES';
No row returned.
combine the above two in to 1 SQL, and return 1 , null or 1, 1. I assume we can get it with left join for the condition "o.stat_name (+) = 'NUM_CPU_CORES'" , but no row returned for the following SQL. How could we get the result for 1, null for this case?
select v.value, o.value -- or NVL(o.value, 1)
from v$parameter v, v$osstat o
where v.name = 'cpu_count'
and o.stat_name (+) = 'NUM_CPU_CORES';
no row returned
I am trying to develop an application of cars. The car have marques example :
TOYOTA,HUNDAI,CHEVROLET
each mark have families example: TOYOTA have Hilux, yaris corola, CHEVROLET have opra,...etc. Each family have a lot of models example: hilux have h2kn-clim,.. etc. And finally there are some options witch are generally in all cars example Radio-k7,air-conditioner ... etc.
option 1..n-----------------1..n model the relation call(opt_mod)
i did develop the block of marques (master) and the block of families (detail) in a form 1. i did develop the bock of models(master) in form 2 and the is no problem. but i want to add to form 2 the block of (opt_mod) but the user did tell me that he want to to see all options with check boxes .
As a solution of this problem i want to build a block on LEFT JOIN between table :option and table :opt_mod
how to assign the values by taking the values on LEFT HAND SIDE DYNAMICALLY.
Say if I have a,b,c,d in an array then I need to take variables from the array and assign some values to it. Like a=1;b=2;c=3;d=4;
What is the fundamental difference between MINUS keyword and LEFT outer join in Oracle.
I can achieve same results using either one of them.
We just upgraded to 11g and have run into incorrect results for some of our LEFT JOINs. If the table, view, subquery, or WITH clause that is being LEFT JOINed to contains any constants, the results are not correct.
For example, a test (nonsensical) view such as the following is created:
create or replace view fyvtst1 as
select spriden_pidm as fyvtst1_pidm,
'Sch' as fyvtst1_test
from spriden
where spriden_last_name like 'Sch%' ;
When I run the following query, I get correct results; that is, only those with "Sch" starting their last name are listed.
select spriden_pidm, spriden_last_name, fyvtst1_pidm, fyvtst1_test
from spriden
join fyvtst1 on fyvtst1_pidm = spriden_pidm ;
However, when I change the JOIN to a LEFT JOIN, the last column contains "Sch" for all rows, instead of NULL:
select spriden_pidm, spriden_last_name, fyvtst1_pidm, fyvtst1_test
from spriden
left join fyvtst1 on fyvtst1_pidm = spriden_pidm ;
We've discovered other quirky things related to this. A WITH clause with similar logic as the above view, when LEFT JOINed to a table will also cause the constant to appear in each row, instead of NULL (and only the value where there is a join). But when additional columns are added to the WITH, it behaves correctly.
This is easy enough to rewrite - but we have WITHs and views containing constants in numerous places, and cannot hope to track down every single one successfully before the incorrect results are used.
Finally, the NO_QUERY_TRANSFORMATION hint will force the query to work correctly. Unfortunately, it has a huge negative performance impact (one query ran for an hour, vs. 1 second in 10g).
I am trying to understand "ordered" hint. I want to use it in my sql where I am using some left outer joins. I believe if I use this ordered hint it will be much faster.
But the problem is I am not able to understand the concept of this hint. As i did alot of search on this eveyone says it will be , even I got some similar references where it worked But I am getting contradicting explanation for on this.
