I am trying to compare a date defined by the user with a date I have in a table and count 7 days at a time until the dates match. Basically, it’s counting weeks, but how can I get it update the date in the cursor?
Set Date BRITISH
users_year = Year(users_date) && users_date is a public variable in week1get.scx
Select * From "t:wiptrack\routecard\week1" Where;
year = users_year Into Cursor ben
Select ben
Goto Top
my_date = ben.firstmon
*count up to week
X = 0
Do While users_date >= my_date
my_date.DATE() + 7 && Trying to add 7 days to date
X = X + 1
If X >= 100
Messagebox("Count is greater than 100")
Endif
Loop
Enddo
You have to store the new value somewhere after you compute it. In addition, the DATE() function doesn't do what you think. Assuming the my_date variable contains a date, you do this:
my_date = my_date + 7

I have the following query that gets the week of a date:
SELECT pdm.serie, rta.matricula_ant, TO_CHAR (fecha, 'ww') semana,
SUM (rta.kms_acumulados) kms,
COUNT
(DISTINCT (CASE
WHEN v.secuencia BETWEEN rta.sec_origen AND rta.sec_destino
THEN v.cod_inc
ELSE '0'
END
)
)
- 1 numincidencias
FROM (SELECT ms.tren, ms.fecha_origen_tren, ms.secuencia, ri.cod_inc
FROM r_incidencias ri, mer_sitra ms
WHERE ri.cod_serv = ms.tren
AND ri.fecha_origen_tren = ms.fecha_origen_tren
AND ri.cod_tipoin IN (SELECT cod_tipo_iincidencia
FROM v_tipos_incidencias
WHERE grupo = '45')
AND ri.punto_desde = ms.cod_estacion) v,
r_trenes_asignar rta,
r_maquinas rm,
planificador.pl_dh_material pdm
WHERE rta.fecha BETWEEN TO_DATE ('21/09/2018', 'dd/mm/yyyy') AND TO_DATE ('21/09/2018',
'dd/mm/yyyy'
)
AND rta.serie >= 4000
AND rta.matricula_ant IS NOT NULL
AND rm.matricula_maq = rta.matricula_ant
AND rm.cod_serie = pdm.id_material
AND rta.grafico BETWEEN pdm.desde AND pdm.hasta
AND v.tren(+) = rta.tren
AND v.fecha_origen_tren(+) = rta.fecha
GROUP BY pdm.serie, rta.matricula_ant, TO_CHAR (fecha, 'ww')
ORDER BY pdm.serie, rta.matricula_ant, TO_CHAR (fecha, 'ww')
For example week 1
I want to display
week 1 : 1 january - 7 january
How can I get this?
Oracle offers the TRUNC(datestamp, format) function to manipulate dates this way. You may use a variety of format strings to get the first day of a quarter, year, or even the top of the hour.
Given a particular datestamp value, Oracle returns midnight on the first day of the present week with this expression:
TRUNC(datestamp,'DY')
You can add days to a datestamp. Therefore this expression gives you midnight on the last day of the week
TRUNC(datestamp,'DY') + 6
A WHERE-clause selector for all rows in the present week might be this.
WHERE datestamp >= TRUNC(SYSDATE,'DY')
AND datestamp < TRUNC(SYSDATE,'DY') + 7
Notice that the end of the range is just before (<) midnight on the first day of the next week. You need that because you may have datestamps after midnight on the last day of the week. (Beware using BETWEEN for datestamp ranges.)
And,
SELECT TO_CHAR(TRUNC(SYSDATE,'DY'),'YYYY-MM-DD'),
TO_CHAR(TRUNC(SYSDATE,'DY')+6,'YYYY-MM-DD')
FROM DUAL;
displays the first and last dates of the present week in ISO-like format.
Date arithmetic is cool. It's worth your trouble to study the date-arithmetic functions in your DBMS at least once a year.
I have the following code -
CMD = new OracleCommand("SELECT * FROM BOOKINGSV3 WHERE DT = :DateInQuestion ", Con);
CMD.Parameters.Add("DateInQuestion", OracleDbType.Date).Value = DateTime.Today;
DT is a Date column, I know Oracle stores dates explicitly and if I try manually with '14-AUG-17 00:00:00' I can retrieve the desired results. How can I search by a date using a parameter other than using a string parameter and constructing a string in the format '14-AUG-17 00:00:00'?
If your DT values have non-midnight times then to get all values on a given day you can use a range:
SELECT * FROM BOOKINGSV3 WHERE DT >= :DateInQuestion AND DT < :DateInQuestion + 1
The >= means it will find times from midnight onwards; the < .. + 1 will limit to before midnight on the following day.
One way to do this is to create a string containing the date you want to search and change your query to explicitly create a date using the date format you use in your string.
CMD = new OracleCommand("SELECT * FROM BOOKINGSV3 WHERE DT = to_date(':DateInQuestion','DD-MM-YYYY HH24:MI:SS') ", Con);
This way you control the date format and not some NLS setting.
I have a table like this:
[Date] [hour] [valid] [value] [type]
And I need to do the averange for each hour of the 23 previous values and itself (24 values) and only if I have 18 or more valid values.
I do with one hour with this query:
select type, avg(value)
from table
where type = 10
and valid = 1
and ((date = '11/10/2016' and hour <= 22) or
(date = '11/09/2016' and hour > 22))
group by type
having count(*)>=18;
But I need to do it with a date interval for each hour in that interval.
It can be possible?
Thank you.
Sorry but keeping date separately with hour is not good. So I'll merge it into date in with clause. If you don't want that you can use to_date(date || ':' || hour, 'dd/mm/yyyy:hh24') everywhere where I have d and ignore with clause
with dat as (select to_date(date || ':' || hour, 'dd/mm/yyyy:hh24') d, valid, value, type from table)
select d1.d, d1.type, avg(d2.value)
from dat d1 cross join dat d2
where d1.d < (d2.d + 1) and d1.d >= d2.d and d2.valid = 1
group by d1.d, d1.type
having count(*) >= 18;
I hope it will work. If you provided any test data I would test it.
you may write next, I assume column valid contains Y and N values.
select type
,max(avg1)
from (
select type
,avg(value) over (order by trunc(date,'HH') range between interval '24' hour preceding and interval '0' hour following ) as avg1
,count(decode(valid,'Y',1)) over (order by trunc(date,'HH') range between interval '24' hour preceding and interval '0' hour following ) as count1
from table
where type = 10
and valid = 1)
where count1 >= 18
group by type;
I want a code which is used to generate aggregate product by product. The product aggregate can be any like from Year to Date(YTD), Months to Date(MTD) and Quarter to Date(QTD). The user will pass the parameter on that basis the code should decide what kind of output the user wants.
If the Year is passing in the parameter than the code should generate the aggregate from the starting of the year to the sysdate.
If the Quarter No is passing in the parameter than the code should generate the aggregate from the starting of the quarter to the sysdate.
If the Month is passing in the parameter than the code should generate the aggregate from the starting of the month to the sysdate.
It means that on the basis of the parameter it should be able to decide which kind of user want from those 3. My input data is like this-
Product Table
Product_ID Product_name Price
1 Mobile 200
2 T.V. 400
3 Mixer 300
and
Sales Table-
Product_ID Sales_Date Quantity
1 01-01-2015 30
2 03-01-2015 40
3 06-02-2015 10
1 22-03-2015 30
2 09-04-2015 10
3 21-05-2015 40
1 04-06-2015 40
2 29-07-2015 30
1 31-08-2015 30
3 14-09-2015 30
And my ouput column contains 3 columns that are- Product_id, Product_Name and Total. The column Total_Amount(quantity*price) have to calculate sale on the basis of input given by user and is be something like this-
For example ,
If pro_test is the procedure then
call pro_test('YTD') -- Should Return the ProductWise YTD,
call pro_test('QTD') -- Should Return the ProductWise QTD and so on..
You are looking for a WHERE clause :-) List your conditions with OR and you are done.
select
p.product_id,
p.product_name,
coalesce(sum(s.quantity * p.price), 0) as total
from product p
left join sales s on s.product_id = p.product_id
where
(:aggregate = 'YTD' and to_char(s.sales_date, 'yyyy') = to_char(sysdate, 'yyyy'))
or
(:aggregate = 'MTD' and to_char(s.sales_date, 'yyyymm') = to_char(sysdate, 'yyyymm'))
or
(:aggregate = 'QTD' and to_char(s.sales_date, 'yyyyq') = to_char(sysdate, 'yyyyq'))
group by p.product_id, p.product_name;
EDIT: Here is how the corresponding PL/SQL function would look like:
create or replace function matches_date_aggregate(in_sales_date date, in_aggregate char)
return integer as
begin
if (in_aggregate = 'YTD' and to_char(in_sales_date, 'yyyy') = to_char(sysdate, 'yyyy'))
or (in_aggregate = 'MTD' and to_char(in_sales_date, 'yyyymm') = to_char(sysdate, 'yyyymm'))
or (in_aggregate = 'QTD' and to_char(in_sales_date, 'yyyyq') = to_char(sysdate, 'yyyyq')) then
return 1;
else
return 0;
end if;
end matches_date_aggregate;
Your query's WHERE clause would become:
where matches_date_aggregate(s.sales_date, :aggregate) = 1
The function cannot return BOOLEAN unfortunately, for even though Oracle's PL/SQL knows the BOOLEAN data type, Oracle SQL doesn't.
I have below query but instead of to be putting range of week like '22-OCT-2012 AND 28-OCT-2012' I woulk to put a code like CurrentWeek -2 or CurrentWeek-1, that will avoid to edit the query every week that I need to run it.
Do you know how make this?

If I understood your question then u can use this to pass the current week days like this
SUM (CASE WHEN (OPERATION.STATUS ='C' AND OPERATION.CLOSE_DATE BETWEEN to_char(trunc(sysdate),'DD-MON-YYYY') and to_char(trunc(sysdate)-6,'DD-MON-YYYY')) THEN OPERATION.RUN_HRS ELSE 0 END) WEEK43
Hope this help u
In this case I will use trunc function:
currentweek will be trunc(sysdate,'D')
current_week - 1 will be trunc(sysdate,'D') - 7
current week - 2 will be trunc(sysdate,'D') - 2 * 7
Attention this will give first day of week sunday. If you want monday you should and one day:
current week - 2 will be trunc(sysdate,'D') - 2 * 7 + 1
UPDATE:
Frank is right, the behavior on first day of week depends on NLS_TERITORY
alter session set NLS_TERRITORY ='UNITED KINGDOM';
select trunc(sysdate,'D') from dual;
05-11-2012
alter session set NLS_TERRITORY ='AMERICA';
select trunc(sysdate,'D') from dual;
04-11-2012
