How do I write a query to display records where sample1_id = 3 and sample2_id = 5 or Sample1_id = 5 and sample2_id =3.
Meaning it should check the row of sample1_id and see wherever there is a record of 5 in line with sample2_id having a record of 3 and also checked if sample1_id is having a record of 5 line with sample2_id having a record of 3.
I hope my question do make sense
Just going by what you have provided, a mock statement would look like this:
SELECT *
FROM MyTable
WHERE (sample1_id = 3 AND sample2_id = 5)
OR (sample1_id = 5 AND sample2_id = 3);
If this is not correct, please provide some sample data and a sample of the results you would like.
Added the following in response to question about using variables:
DECLARE #intId1 int,
#intId2 int;
SET #intId1 = 3;
SET #intId2 = 5;
BEGIN;
SELECT *
FROM MyTable
WHERE (sample1_id = #intId1 AND sample2_id = #intId2)
OR (sample1_id = #intId2 AND sample2_id = #intId1);
END;

I have a table as follows:
Id = stretch(1..100,1000)
area = take(`A`B`C`D`E`F`G`H`I`J,1000)
qyt = rand(100.00,1000)
t = table(Id,area,qyt)
I want to query data with multiple field values.
Query condition:
field value “Id=1“, “area“ = A, F, G;
field value “Id=2“, “area“ = B, C, D;
field value “Id=3“, “area“ = B, C, G;
I tried the following method, querying each record with a where clause.
select * from t where (Id =1 and area = `A) or (Id = 1 and area = `F) or(Id = 1 and area = `G)
The code is simple but long. Is there any easier way to solve this problem?
The query condition involves field “Id“ and “area“. First, you can add a new field “newCol“ that combines these two fields.
temp = select *,string(Id)+area as newCol from t
Then, conduct a query as follows:
aim_row = `1A`1F`1G`2B`2C`2D`3B`3C`3G
result = select Id,area, qyt from temp where newCol in aim_row
Output:
Id area qyt

So I have the following table:
And I'm trying to write a Query where I can send the code BR_BN as a variable in my WHERE clause
and if I get BR_BN then I want to retrieve the records with this code AND the records with the Code_FS RB02. On the other side when I get the value AB_CP, I want to include the recordes with the Code_FS RB01.
Here's the Query I've tried so far:
DECLARE #Code_OB VARCHAR(20) = 'BR_BN'
SELECT * FROM Dummy_AV
WHERE FK = 2
OR
(#Code_OB = 'BR_BN' AND Code_FS = 'RB02' AND Code_FS = #Code_OB)
But it doesn't work, it retrieves all the records regardless of the FK, and/or the #Code_FS.
How can I achieve this?
Thanks for the help.
You don't note the FK = 2 being needed, yet you have it in front of an OR in the WHERE clause. I think this is what you're after, if it isn't exactly what you're aiming for hopefully it gets you on the right track. For future questions, always helpful to paste your sample data as data instead of an image.
DECLARE #Code_OB VARCHAR(20) = 'BR_BN'
SELECT * FROM Dummy_AV
WHERE FK = 2 -- you will get all rows where this is true
OR
((#Code_OB = Code_OB AND Code_FS = 'RB02') OR (Code_OB = 'AB_CP' AND Code_FS = 'RB01')) -- you will get all rows where one of these is true
Hello I have a procedure and questions about it. This procedure is used for extracting data then inserting them into one table. When I test my code, I have to enter some parameters for executing procedure.
`--this is how I execute the procedure
begin
GPU_DATA_EXTRACTOR(to_date('31/08/2021','DD/MM/YYYY'));
end;`
But what I want to do is that when the billdate parameter is NULL, the procedure should execute last day of the previous month as a parameter automatically. How can I make this change? I am open to any update advices thank you from now.
Updated the script below.
create or replace procedure GPU_DATA_EXTRACTOR_TEST(pid_billdate DATE DEFAULT LAST_DAY(ADD_MONTHS(TRUNC(SYSDATE), -1))) is

You can add a default value for your parameters. Take the following function as an example:
CREATE OR REPLACE FUNCTION sf_showDefault
(
p_in DATE DEFAULT LAST_DAY(ADD_MONTHS(TRUNC(SYSDATE), -1))
)
RETURN DATE
IS
BEGIN
RETURN p_in;
END sf_showDefault;
/
When no parameters are entered it gets a truncated SYSDATE and subtracts one month, then if finds the last day of that month. All the function does is return that data (or the one that you pass in...if you feel like it).
Here is a DBFiddle showing the effect of DEFAULT parameters (LINK)
I have 2 tables in my SQL Server database, for example [Camera] and [CameraData]. How to write a trigger which will change value in [CameraData] after row is inserted into [CameraData] due to delta in [Camera].
For example we have 2 cameras in [Camera]:
Camera 1 with {id} = 1 and {delta} = null
Camera 2 with {id} = 2 and {delta} = 3
So when we have automated insert into table [CameraData], f.e. :
Id_camera = 2, angle = 30, Changed = null
In that case we need to check either we have delta in [Camera] on camera 2 and if that's true we need to modify insert to:
Id_camera = 2, angle = 33 (angle + Camera.Delta), Changed = True
Update 1
According to comment [3] is the column in table [CameraData] where angle is placed
CREATE TRIGGER Delta_Angle
ON CameraData
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
UPDATE CameraData
SET DeltaFlag = 1, [3] = inserted.[3] + i.DeltaAngle
FROM CameraData h
INNER JOIN Camera i ON h.ID_Camera = i.ID_Camera
WHERE i.DeltaAngle != ''
END
This is very much a stab in the dark, as your sample SQL isn't at all representative of the data your describe in your question, however, maybe something like:
CREATE TRIGGER Delta_Angle ON CameraData
AFTER INSERT AS
BEGIN
SET NOCOUNT ON;
UPDATE C
SET Angle = C.Angle + i.delta
FROM Camera
JOIN inserted i ON C.CameraID = i.CameraID;
END
Notice that I refer to inserted; your trigger wasn't. Also, I'm not sure about your clause i.DeltaAngle != ''. Considering that DeltaAngle appears to be an int, it can never have a value of '' (however, '' would be implicitly converted to the value 0).
If this doesn't help, I (again) suggest you read Sean's link and update your post accordingly.
im trying to merge into a table.
this select doesnt find anything:
select * from dpr where dpr_qot_id=1111;
then i run this merge like the follwing:
MERGE INTO dpr d
USING (select dpr_ts, dpr_qot_id
from dpr
where dpr_qot_id = 1111
and dpr_ts = to_date('30.11.1999', 'DD.MM.YYYY')) s
on (s.dpr_ts = d.dpr_ts and s.dpr_qot_id = d.dpr_qot_id)
when not matched then
insert
(DPR_TS,
DPR_CLOSE,
DPR_OPEN,
DPR_HIGH,
DPR_LOW,
DPR_VOLUME,
DPR_QOT_ID)
values
(to_date('30.11.2010', 'DD.MM.YYYY'),
21.66,
21.75,
22.005,
21.66,
2556.00,
1111)
WHEN MATCHED THEN
UPDATE
set DPR_CLOSE = 21.66,
DPR_OPEN = 21.75,
DPR_HIGH = 22.005,
DPR_LOW = 21.66,
DPR_VOLUME = 2556.00;
and still this select doesn't find anything:
select * from dpr where dpr_qot_id=1111;
What am i doing wrong?
Thank you!
Greetings
Magda
Since there are no dpr rows where dpr_qot_id=1111, the source (USING) query of your MATCH will also contain no rows, so there is no data to be merged - and so nothing is done.
