In Oracle SQL, I wish to find all user names,whose Last name contains some specific Characters like ('Z','X','D','F') Or contains Some Range of Characters from 'A-F'.
I tried this:
SELECT user_last_name
FROM userbase
WHERE user_last_name LIKE '%A%' OR user_last_name LIKE '%F%' .
So How can I go about it.
And I written facebook in question although its not directly related to it,because,its the example given by my sir.
UPDATE: I tried the above code,it works with so many OR's, but How can we define some range to search for like IN('Z','X','D','F') or IN ('A-F')
If you are using a recent version of Oracle, you should be able to use regular expressions
SQL> ed
Wrote file afiedt.buf
1 select first_name, last_name
2 from employees
3* where regexp_like( last_name, 'Z|X|D|[A-F]' )

You can use INSTR to test whether characters exist in your field, like so:
SELECT
user_last_name
FROM
userbase
WHERE 0 < INSTR(user_last_name,'A')
or 0 < INSTR(user_last_name,'B')
...repeat for each character you want to test for...

Hello Everyone I have a problem…
Table 1 (sorted) is laid out like this:
User ID Producer ID Company Number
JWROSE 23401 234
KXPEAR 23903 239
LMWEEM 27902 279
KJMORS 18301 183
Table 2 (unsorted) looks like this:
Client Name City Company Number
Rajat Smith London JWROSE
Robert Singh Cleveland KXPEAR
Alberto Johnson New York City LMWEEM
Betty Lee Dallas KJMORS
Chase Galvez Houston 23401
Hassan Jackson Seattle 23903
Tooti Fruity Boise 27902
Joe Trump Tokyo 18301
Donald Biden Cairo 234
Mike Harris Rome 239
Kamala Pence Moscow 279
Adolf Washington Bangkok 183
Now… Table 1 has all of the User IDs and Producer IDs properly rowed with the Company Number.
I want to pull all the data and correctly sorted….
Client Name City User ID Producer ID Company Number
Rajat Smith London JWROSE 23401 234
Robert Singh Cleveland KXPEAR 23903 239
Alberto Johnson New York City LMWEEM 27902 279
Betty Lee Dallas KJMORS 18301 183
Chase Galvez Houston JWROSE 23401 234
Hassan Jackson Seattle KXPEAR 23903 239
Tooti Fruity Boise LMWEEM 27902 279
Joe Trump Tokyo KJMORS 18301 183
Donald Biden Cairo JWROSE 23401 234
Mike Harris Rome KXPEAR 23903 239
Kamala Pence Moscow LMWEEM 27902 279
Adolf Washington Bangkok KJMORS 18301 183
Query:
Select
b.client_name,
b.city.,
a.user_id,
a.producer_id,
a.company_number
From Table 1 A
Left Join Table 2 B On a.company….
And this is where I don’t know what do to….because both tables have all the same variables, but Company Number in Table 2 is mixed with User IDs and Producer IDs... however we know what company Number those ID's are associated to.
As I mention in the comments, and others do, the real problem is your design. "The fact that UserID is clearly a varchar, while the other 2 columns are an int really does not make this any better", and makes this not simple (and certainly not SARGable).
To get the data in the correct order, as well, you need a column to order it on which the data lacks. I have therefore added a pseudo column, MissingIDColumn, to represent this missing column you need to add to your data; which you can do when you fix the design:
SELECT T2.ClientName,
T2.City,
T1.UserID,
T1.ProducerID,
T1.CompanyNumber
FROM (VALUES('JWROSE',23401,234),
('KXPEAR',23903,239),
('LMWEEM',27902,279),
('KJMORS',18301,183))T1(UserID,ProducerID,CompanyNumber)
JOIN (VALUES(1,'Rajat Smith ','London ','JWROSE'),
(2,'Robert Singh ','Cleveland ','KXPEAR'),
(3,'Alberto Johnson ','New York City','LMWEEM'),
(4,'Betty Lee ','Dallas ','KJMORS'),
(5,'Chase Galvez ','Houston ','23401'),
(6,'Hassan Jackson ','Seattle ','23903'),
(7,'Tooti Fruity ','Boise ','27902'),
(8,'Joe Trump ','Tokyo ','18301'),
(9,'Donald Biden ','Cairo ','234'),
(10,'Mike Harris ','Rome ','239'),
(11,'Kamala Pence ','Moscow ','279'),
(12,'Adolf Washington','Bangkok ','183'))T2(MissingIDColumn,ClientName,City,CompanyNumber) ON T2.CompanyNumber IN (T1.UserID,CONVERT(varchar(6),T1.ProducerID),CONVERT(varchar(6),T1.CompanyNumber))
ORDER BY MissingIDColumn;
I have a question to ask and I am supposed to create a query which shows:
MIN(lastname) MAX(firstname) SUM(salary) AVG(salary)
---------------------------------------------------------------
DAVIES TRINA 17500 3500
This was the query/queries I created:
SQL> SELECT MIN(LASTNAME), MAX(FIRSTNAME), SUM(SALARY), AVG(SALARY)
2 FROM EMPLOYEES
3 GROUP BY JOB_ID;
SQL> SELECT MIN(LASTNAME), MAX(FIRSTNAME), SUM(SALARY), AVG(SALARY)
2 FROM EMPLOYEES
3 GROUP BY JOB_ID, MANAGER_ID;
But I get multiple rows shown to me and in the part where DAVIES TRINA was shown the SUM and AVG salary is different and I am unsure how they were grouped.
MIN(LASTNAME) MAX(FIRSTNAME) SUM(SALARY) AVG(SALARY)

If you provide the proper data that is, the data before running the query/queries and also tell why it should be 17500(sum) and 3500(avg) then you have more chances to get answers.
In the 1st query you are grouping based on JOB_ID. That means for all similar JOB_IDs (in case of SUM(SALARY)) it will select the the values of SALARY column and SUM the values for each different JOB_ID.
Example:
JOB_ID SALARY
1 200
2 300
1 150
2 100
3 270
If you run the following query:
Select JOB_ID,SUM(SALARY) FROM Table GROUP BY JOB_ID
Output:
JOB_ID SALARY
1 350
2 400
3 270
I am not able to understand the behavior of the following query:
select max(avg(salary)) from employees
group by first_name
having avg(salary) >= max(salary);
It prints out the result as 17000. But if max(salary) is 24000 shouldn't there be empty result. If I replace "">="" with ">" it prints the result as NULL.
And if I replace ">=" with "<", then 13100 is printed in the result.

You are doing Group By First_name, in your table,
For Neena, max(salary) = 17000 and avg(salary)=17000,
So, >= matches the condition in the query and 17000 is returned.
Where as replacing >= with > evaulated to NULL.
For Steven, Max(salary)=24000, AVG(salary)=(24000+2200)/2=13100
So replacing >= with < returns 13100
Note : Grouping by ColumnName here first_name plays the key role
here. All the aggregate functions in SELECT as well as having clause,
are applied per employee and not on the whole table.
If you want to compare an employee's mean salary (does this really make sense? Surely an employee only has one salary at a point in time?) then this might help

I am new to SQL and am practicing on the HR schema available on Oracle 10g XE.
This is the question:
Write a query to select the name, job, and salary and department number of all employees except Sales Rep from department number 80.
My query is this:
select first_name||' '||last_name "Employee Name"
, job_id, salary, department_id
from employees
where not( job_id='SA_REP' and department_id=80 )
order by department_id;
Output:
Employee Name JOB_ID SALARY DEPARTMENT_ID

I am not however getting the desired output,as the output is not displaying this row:
Employee Name JOB_ID SALARY DEPARTMENT_ID
---------------------------------------------- ---------- ---------- -------------
Kimberely Grant SA_REP 7000
This record does not have a department number, but it should also be displayed in the output along with the other 77 rows. Can anyone please point out where i am going wrong with the query?
So the goal is to get a list of all employees except those who are sales reps and in department 80? That is, you still want employees in department 80 (as well as all other departments) unless they are sales reps, and sales reps unless they are in department 80?
In Oracle, the comparison of a NULL value with anything else returns NULL rather than TRUE or FALSE. So you'll want to either: (a) add an explicit IS NULL condition (or IS NOT NULL, depending on your query parameters) or (b) use the COALESCE() (or NVL()) function. Something like this:
SELECT first_name || ' ' || last_name "Employee Name"
, job_id, salary, department_id
FROM employees
WHERE job_id != 'SA_REP'
OR department_id IS NULL
OR department_id != 80
ORDER BY department_id;
or:
SELECT first_name || ' ' || last_name "Employee Name"
, job_id, salary, department_id
FROM employees
WHERE job_id != 'SA_REP'
OR COALESCE(department_id, 0) != 80
ORDER BY department_id;
Thanks to #DavidFaber for confirming my original thought. The not that you have in your where clause isn't playing nice with the department_id = 80 portion, because of the empty value for Kimbereley Grant in department_id. Basically, the "not (job_id='SA_REP' and department_id=80)" becomes "not job_id='SA_REP' or not department_id=80", hence "job_id != 'SA_REP' or department_id != 80".
Kimberely Grant fails the first check (her job_id is in fact SA_REP) and the second check should result in essentially, "Unknown" (her department_id is not 80, but it's not not 80 either, it's NULL). As a result, you have false or "Unknown" which becomes false.
The fix is what #Ponder suggested. Add a null check on department_id:
not (job_id='SA_REP' and department_id=80 and department_id is not null)
which is equivalent to:
not (job_id='SA_REP' and department_id=80) or department_id is null
Thanks every one. I am able to get the required output now with this query:
SELECT first_name || ' ' || last_name "Employee Name"
, job_id, salary, department_id
FROM employees
WHERE job_id != 'SA_REP'
OR department_id IS NULL
OR department_id != 80
ORDER BY department_id;
Many Thanks again.Cheers.
HI all I am fairly new to Shell Scripting .. I was testing a sample report in which I was trying to spool the output of sql query embedded in shell script. here is my code
#!/bin/sh
ORACLE_ACCESS=hr/hr#xe
# Report file location
FILE_LOCATION=/home/$USER/Documents/loaddata/
#File Name
FILE_NAME=Report_`date +%y%m%d`.csv
sqlplus -s $ORACLE_ACCESS <<EOF 2>log.txt
set serveroutout on
set echo off
set first_name format A120
spool ${FILE_LOCATION}${FILE_NAME}
select first_name,last_name
from employees;
exit;
EOF
sql_error=$?
if [$sql_error !=0]; then
echo "Error"
exit 1
fi
However I am getting a pretty badly formatted output.
below is the sample
FIRST_NAME LAST_NAME
Ellen Abel
Sundar Ande
Mozhe Atkinson
David Austin
Hermann Baer
Shelli Baida
Amit Banda
Elizabeth Bates
Sarah Bell
David Bernstein
Laura Bissot
FIRST_NAME LAST_NAME
Harrison Bloom
Alexis Bull
Anthony Cabrio
Gerald Cambrault
Nanette Cambrault
John Chen
Kelly Chung
Karen Colmenares
My intended output should look something like below
First_name Last_name
Atlas Levine
John Doe
can somebody help?
Is your intended output like
First_name Last_name
Atlas Levine
John Doe
If so you can use something like set pagesize 10000 or something large so that the header doesnt get repeated. If you want to skip the header you can just set it to 0 You can refer the answers and links in Formatting output of queries in SQLPlus along with many other similar questions
