View 3 Replies View RelatedSQL & PL/SQL :: Left Outer Join Or Function
Oct 13, 2010I 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.

PL/SQL :: Find Equivalent Of Mysql_data_seek In Oracle
Oct 23, 2012"php 5.3.x + oracle 11g R2 XE 11.2.x.x"...I'm quite new to oracle (2-4 months) and php(2 weeks).I have one query with results that needs to be reused in several parts of my website. I can't seem to find the equivalent of the mysql_data_seek in Oracle. I wanted to reset the cursor/pointer of oci_ fetch ($result) so that I can scroll the result again.So far this are what I have come up:
A. On first fetch put the the results in a php array and call the array later on.
B. Do the query again.
C. Keep on looking for a mysql_data_seek equivalent and fail.
I'm leaning towards option 'A' but I just wanted to consult the experts.
SQL & PL/SQL :: Date Diff (Month Not Day) Equivalent In Oracle
Jun 16, 2010I see month aging buckets in the Oracle Application I am using (Keystone time and billing). I need to do a query in directly in Oracle (Toad front end to Keystone database) using month aging buckets . I use the following in Access that matches the results in Oracle, but I need to work directly in Toad because I want to avoid having to bring over all the dates when I want to summarize by buckets.:
2-4 Months: Sum(IIf(DateDiff("m",[invoice date],forms!Reporting_Standard!txtlastdayofmonth) In (2,3),[Outstanding Gross],0))
I know about getting the difference between two dates and that works fine for day aging buckets, but I need months, which can deal with months that are different sizes.

Upgrade :: 10g Companion CD Equivalent In 11g?
Sep 25, 2013I am upgrading from 11.2.0.1 to 11.2.0.3 (64 bit) on Windows (64 bit) I planned to install Oracle 11.2.0.3 on new home and i am not sure wheteher i have to install: Oracle Gateway and Oracle Examples on the 11.2.0.3 new home. I am not using any non - oracle so i may not need Oracle Gateway. I am not sure about examples media . Does it have only examples to learn (or)will it have any optional components which we may require (like companion CD in 10g)? What about the ODBC and com components will it be installed with the database media itself? After DB upgradation is it possible to install oracle gateway/examples on the same home?
View 2 Replies View RelatedSQL & PL/SQL :: Query Must Return All Equivalent Records
Nov 26, 2012I've stucked with a query. I have a table that i store the IDs of logically equal records.
For example;
A = B
B = C
X = Y
Z = Y
My query must return all equivalent records. If you call the query with parameter 'A', the result set must contain B and C. And if you call the query with parameter 'Y', the result set will contain X AND Z. I have thought that i can write the query wity using start with connect by statement. But the query does not work as i expected. Here is my code and sample data:
create table temptable (ID1 number,ID2 number);/
insert into temptable values(11,12);/
insert into temptable values(12,13);/
insert into temptable values(13,14);/
insert into temptable values(13,15);/
SELECT distinct ID1 from
(
SELECT * FROM temptable
START WITH ID1 = 13 OR ID2 = 13
CONNECT BY NOCYCLE
(
(PRIOR ID1 = ID1) OR
(PRIOR ID1 = ID2) OR
(PRIOR ID2 = ID1) OR
(PRIOR ID2 = ID2))
) WHERE ID1 <> 13
union
[code]....
When i call the query with parameter 13, i'm expecting to get 11,12,14,15. But it returns only 12,14 and 15.

SQL & PL/SQL :: Use Greater And Less Than In Left Join?
Apr 9, 2013I 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);
SQL & PL/SQL :: LEFT JOIN And NVL Isn't Working
Nov 29, 2011Using Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
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?

Left Joining Select Of Multiple Tables
Nov 22, 2010i 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.
SQL & PL/SQL :: Left Join With Fixed String Failed?
Jun 17, 2010I 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
