Using Case Or If To Get Grade?

Feb 7, 2007

Im trying to make a query to get the grades of students, I already figured out how to get the average from the exams. Now I would like to make like a select case or if statements to get the actual grade.

Something like this:
average > 89 then grade = 'A'
average > 79 then grade = 'B'
average > 69 then grade = 'C'
average > 59 then grade = 'D'
else grade = 'F'

How To Use CASE When Set Query Empty

Mar 23, 2009

I have a query that will either return one record or zero records. When it returns zero records I want to replace my attributes with a sentinel, like 'N/A'. I tried the CASE statement but couldn't get anything to work

Sample (does not work):
select
(case when exists (select product from tbl_product where productid = '123') then product else 'N/A' end) product
from tbl_product
where productid= '123';
If one record exists it should produce: 'My Widget' (or whatever)
If zero records exist it should produce: 'N/A'

SQL & PL/SQL :: Case Statement In Where Clause

Aug 10, 2011

select empno,ename,deptno,employee_status from emp,dept where emp.deptno=dept.deptno and
( employee_status in(Case employee_status when {?Status}=1 then 'A'
when {?Status}= 2 then 'T'
When {?Status}= 3 then 'A'||','||'T'))
OR ( end_date >= {?START_DATE}
AND end_date <= {?END_DATE}
)
)

Since when i pass employee_status as input 1 it have given me 4 records. When I pass employee_status as input 2 it have given me 3 records. When I pass employee_status as input 3 it should give me 4 records + 3 records=7 records.

4 records for employee_status 'A'
3 RECORDS for employee_status 'T'
7 records for employee_status 'A' AND 'T'

How I should write a query to get 7 records.

SQL & PL/SQL :: Display Results Using CASE WHEN?

May 24, 2011

I am trying to create a query that displays the given error message if the result of my COUNT(*) is smaller than 1, but displays the result of my first query (data) if the total count is bigger than 1 (read: the query found data, so it needs to display the rows according to the search).

What do I need to do to display 'data' if 'data2' contains rows?

WITH data

b.funct_prod_code, b.sts_status_code, b.ost_order_situation_code, c.order_situation_oms,

SQL & PL/SQL :: DECODE And CASE In WHERE Clause

May 7, 2010

I am facing a problem while retrieving data from table using DECODE/CASE.

Table: PARAM_MSTR

MIN_VALMAX_VALPARAM_CODE DESCRIPTION DATATYPE
AB1000 HARD PARAMETERTEXT
CN1000 SOFT PARAMETERTEXT
0501001 CRYSTAL PARAMETERNUMBER
512001001 STONE PARAMETERNUMBER

Now I want to get the parameter description based upon the PARAM_CODE and a value passed which should be in range of MIN_VAL and MAX_VAL. Means when I pass PARAM_CODE=1000 and :parameter=A, then it should check the DATATYPE of the PARAM_CODE, in our case it is 'TEXT' so it should check the passed value between MIN_VAL and MAX_VAL like

:parameter BETWEEN MIN_VAL AND MAX_VAL and should return 'HARD PARAMETER'.
If I pass PARAM_CODE=1001, then the DATA_TYPE is 'NUMBER', so it will check the :parameter value as Number.
Like :parameter BETWEEN to_number(MIN_VAL) AND to_number(MAX_VAL)

For example:
PARAM_CODE :parametr Result
1000 A HARD PARAMETER
1000 C SOFT PARAMETER
1000 P NULL
1001 25 CRYSTAL PARAMETER
1001 99 STONE PARAMETER
1001 201 NULL

I have written a query using DECODE and CASE statement but it is not working properly.

SELECT * FROM param_mstr WHERE PARAM_CODE=1000 AND :parameter BETWEEN DECODE(DATATYPE,'NUMBER',CAST(MIN_VAL as NUMBER),MIN_VAL)AND DECODE(DATATYPE,'NUMBER',CAST(MAX_VAL as NUMBER),MAX_VAL)

SQL & PL/SQL :: Using Sequence In CASE Statement

Oct 11, 2011

Can we use the sequence.nextval,sequence.currval inside case block.

CREATE TABLE EQUALITY_TEST(NUM1 NUMBER, NUM2 NUMBER, SEQ NUMBER);
INSERT INTO EQUALITY_TEST VALUES ( 2 ,0 , NULL);
INSERT INTO EQUALITY_TEST VALUES ( 2 ,2 , NULL);
INSERT INTO EQUALITY_TEST VALUES ( 2 ,2 , NULL);
INSERT INTO EQUALITY_TEST VALUES ( 12 ,2 , NULL);
INSERT INTO EQUALITY_TEST VALUES ( 12 ,12 , NULL);
INSERT INTO EQUALITY_TEST VALUES ( 12 ,12 , NULL);
CREATE SEQUENCE SEQ_TEMP START WITH 100 INCREMENT BY 1;

Now i need to update SEQ column with SEQ_TEMP sequence. When NUM1,NUM2 values are unequal sequence should be incremented otherwise need to use the same sequence number(CURRVAL)

I have tried like this

UPDATE EQUALITY_TEST
SET SEQ=
CASE WHEN NUM1=NUM2
THEN SEQ_TEMP.NEXTVAL
ELSE
SEQ_TEMP.CURRVAL
END ;
SELECT * FROM EQUALITY_TEST;

Output

NUM1NUM2SEQ
120100
222101
322102
4122103
51212104
61212105

But Required Output

NUM1NUM2SEQ
120100
222100
322100
4122101
51212101
61212101

SQL & PL/SQL :: Select In Case Statement

Feb 11, 2011

I have the following tables:

create table lookups (code varchar2(20), amount number);

insert into lookups values ('Rent' , 500);
insert into lookups values ('Breakpoint' , 10);

create table products (id number, cost number, year varchar2(4));

insert into products values (1, 1000, '2011');
insert into products values (1, 2000, '2011');
insert into products values (2, 100, '2011');
insert into products values (3, 50, '2011');

commit;

I want to write a query which lists the IDs and the sum(cost), and a Y/N indicator which is set to 'Y' IF sum(cost) > ( (lookups.rent value) * (100 - lookups.breakpoint value))/100

I have written this query:

SELECT id,
sum(cost)cost,
year,
CASE
WHEN cost >
((SELECT amount
[code]....... ORDER BY id;

This returns

ID COST YEAR YN
--------- ---------- ---- -
1 1000 2011 Y
1 2000 2011 Y
2 100 2011 N
3 50 2011 N

The YN is correct, but it needs to sum the amounts. So there should only be one row for id1 = 3000.e.g.

ID COST YEAR YN
--------- ---------- ---- -
1 3000 2011 Y
2 100 2011 N
3 50 2011 N

I am not sure how to do this. Or is there a better way of doing this than using CASE.

SQL & PL/SQL :: Query With CASE Where Clause?

May 14, 2012

The query has a case statement in the where clause so that results can be filtered. If I pass "ut" for sso_id then the query returns 21 rows. If I remove the case statement and hard code "a.sso_id like lower('ut'||'%')" then the query returns 41 rows. The query should be returning 41 rows all the time.

Problem:

When passing "ut" as an SSOID parameter to the Procedure the query returns 21 rows.Taking the query and hard coding "a.sso_id like lower('ut'||'%')" the query returns 41 rows.

Result:
query should be returning 41 rows when "ut" is passed an an SSOID parameter.

Returns 21 rows

procedure SSO (SSOID in varchar2 default null,
Name in varchar2 default null,
Campus in varchar2 default null,
Department in varchar2 default null,

[code]...

Returns 41 rows

open Results for

SQL & PL/SQL :: NESTED CASE Statement

Jul 13, 2010

I'm working on a nested case statement, can't seem to get it right.We have a table that has injury_codes. What I'm trying to do is come with a nested case statement that will put the codes in a specific_cat, and based on the specific_Cat, assign a Generic_cat.

Example.
I have codes 11,12,13,14,15, 15, 17, 18, 19, 20, 21, 22
Codes 11, 12, 13 have a specific_cat "Head Injury"
Codes 14, 15, 16 have a specific_cat "Spinal Injury"
Codes 17, 18 have a specific_cat "Burns".

All 3 of these specific_cat come under the generic_cat "Trauma"

Codes 19, 20 have a specific_Cat "High Risk Pregancy"
Codes 21, 22 have a specific_cat "Premature Birth".

All 2 of these specific_cat come under the generic cat "OBGYN"...So my case stement should return :

CODESSPECIFIC_CATGeneric_Cat
11Head InjuryTrauma
12Head InjuryTrauma
13 Head InjuryTrauma
14Spinal InjuryTrauma
15Spinal InjuryTrauma
16Spinal InjuryTrauma
[code]...

just a small sample of codes, specific_Cat and generic_cat. I hundreds of these codes I need to categorize.

else
(select 6,7,8,9,0 from dual)

What I really need is the full result of (select 1,2,3,4,5 from dual) or (select 6,7,8,9,0 from dual) if a condition as a result of a different sql-statement is true or false. It doesn't matter if the solution uses "case when" or anything else.

PL/SQL :: Execution Order In Case Of Row Num

Jul 26, 2012

I just wanted to know how the query will be executed in case of where clause and ROWNUM clause. e.g, consider below query.

SELECT * FROM emp
WHERE dept IN (20, 30, 21)
AND salary < 10000
AND rownum <2;

My question is that when rownum will be executed?

1. First all the data according to where clause will be fetched and rownum is assigned and then rownum will be executed on that data.
2. First complete data will be fetched, ROWNUM will be applied and then WHERE clause will be executed along with ROWNUM clause.
