I try to update several cells, but nothing, could you help me to optimize my query?
with upd AS (
UPDATE era
SET gender = CASE id
WHEN 3 THEN 'Female'
WHEN 4 THEN 'Male'
END,
SET city = CASE id
WHEN 3 THEN 'Minsk'
WHEN 4 THEN 'Brest'
END
WHERE id IN (3, 4)
returning *
)
select * from upd;
I would suggest that you use a derived table for this logic:
WITH upd AS (
UPDATE era
SET gender = v.gender,
city = v.city
FROM (VALUES (3, 'Female', 'Minsk'), (4, 'Male', 'Brest')
) v(id, gender, city)
WHERE v.id = era.id
RETURNING *
)
SELECT *
FROM upd;
Using this method, you don't have to repeat values or use complicated CASE expressions -- both of which are prone to error.
You just not need second SET
with upd AS (
UPDATE era
SET gender = CASE id
WHEN 3 THEN 'Female'
WHEN 4 THEN 'Male'
END,
city = CASE id
WHEN 3 THEN 'Minsk'
WHEN 4 THEN 'Brest'
END
WHERE id IN (3, 4)
returning *
)
select * from upd;

Let's say I am returning the following table from a select
CaseId
DocId
DocumentTypeId
DocumentType
ExpirationDate
1
1
1
I797
01/02/23
1
2
2
I94
01/02/23
1
3
3
Some Other Value
01/02/23
I want to select ONLY the row with DocumentType = 'I797', then if there is no 'I797', I want to select ONLY the row where DocumentType = 'I94'; failing to find either of those two I want to take all rows with any other value of DocumentType.
Using SQL Server ideally.
I think I'm looking for an XOR clause but can't work out how to do that in SQL Server or to get all other values.
Similar to #siggemannen answer
select top 1 with ties
case when DocumentType='I797' then 1
when DocumentType='I94' then 2
else 3
end gr
,docs.*
from docs
order by
case when DocumentType='I797' then 1
when DocumentType='I94' then 2
else 3
end
Shortest:
select top 1 with ties
docs.*
from docs
order by
case when DocumentType='I797' then 1
when DocumentType='I94' then 2
else 3
end
Something like this perhaps:
select *
from (
select t.*, DENSE_RANK() OVER(ORDER BY CASE WHEN DocumentType = 'I797' THEN 0 WHEN DocumentType = 'I94' THEN 1 ELSE 2 END) AS prioorder
from
(
VALUES
(1, 1, 1, N'I797', N'01/02/23')
, (1, 2, 2, N'I94', N'01/02/23')
, (1, 3, 3, N'Some Other Value', N'01/02/23')
, (1, 4, 3, N'Super Sekret', N'01/02/23')
) t (CaseId,DocId,DocumentTypeId,DocumentType,ExpirationDate)
) x
WHERE x.prioorder = 1
The idea is to rank rows by 1, 2, 3 depending on document type. Since we rank "the rest" the same, you will get all rows if I797 and I94 is missing.
select * from YourTable where DocumentType = 'I797'
union
select * from YourTable t where DocumentType = 'I94' and (not exists (select * from YourTable where DocumentType = 'I797'))
union
select * from YourTable t where (not exists (select * from YourTable where DocumentType = 'I797' or DocumentType = 'I94' ))
Hi I need the result of this. so if a entityID matches to a value I need the sum of certain column.I am getting an expression missing error. Can someone point me to where the error is?
Thanks.

As well as the issues mentioned by #GordonLinoff (that AS is a keyword) and #DCookie (you need entityid in the group-by):
you also need acdcalls and daacdcalls in the group-by (unless you can aggregate those);
you can't refer to a column alias in the same level of query, so (weight * meets) AS weightedMeets isn't allowed - you've just define what weight is, in the same select list. You need to use an inline view, or a CTE, if you don't want to repeat the case logic.
I think this does what you want:
SELECT
jobTitle,
department,
person,
meets,
exceeds,
weight,
(weight * meets) AS weightedMeets,
(weight * exceeds) AS weightedExceeds
FROM

ELSE null
END as weight

Your fist two case branches could be combined since the calculation is the same, but will work either way.
In addition to the alias issue identified by Gordon, I think you'll find you need to use an aggregate function in all the THEN clauses of your CASE statement, and that you need to GROUP BY ufr.entityid as well. Otherwise you'll start getting ora-00979 errors (not a GROUP BY expression). If you don't want the aggregate function in all clauses, then you'll have to group by the expressions you're summing as well.

I have two tables A and B
Table A
ID_number as PK
first_name,
L_Name
Table B
ID_number,
Email_id,
Flag
I have several people who have multiple email ID and are already flagged as X on table B.
Whereas i am trying to find list of people who have an email id or multiple email ID, but were never flagged.
e.g John clark might have 2 email in table B, but was never flagged.
Simply use not exists:
select a.*
from a
where not exists (select 1
from b
where b.id_number = a.id_number and b.flag = 'X'
);
You may want to perform an update, but your question seems to be only about selecting (probably to update based on select). It should be something like this:
SELECT A.L_Name
FROM A
WHERE NOT EXISTS (
SELECT 1
FROM B
WHERE B.ID_number = A.ID_number AND B.Flag = 'X'
)
OR the LEFT JOIN version
SELECT 1
FROM A
LEFT JOIN B ON B.ID_number = A.ID_number AND B.Flag = 'X'
WHER B.ID_number IS NULL
Usually, the first version is faster than the second one.
Forget Table A...
SELECT DISTINCT ID_number FROM table_b t1
WHERE NOT EXISTS(
SELECT NULL FROM table_b t2 WHERE t1.ID_number=t2.ID_number AND t2.flag='X'
)
Judging by your responses in the comments, I believe this is what you are looking for:
--drop table update_test;
create table update_test
(
id_num number,
email_id number,
flag varchar2(1) default null
);
insert into update_test values (1, 1, null);
insert into update_test values (1, 2, null);
insert into update_test values (2, 3, null);
insert into update_test values (2, 7, null);
insert into update_test values (3, 2, null);
insert into update_test values (3, 3, 'X');
insert into update_test values (3, 7, null);
select * from update_test;
select id_num, min(email_id)
from update_test
group by id_num;
update update_test ut1
set flag = case
when email_id = (
select min(email_id)
from update_test ut2
where ut2.id_num = ut1.id_num
) then 'X'
else null end
where id_num not in (
select id_num
from update_test
where Flag is not null);
The last update statement will update and set the Flag field on the record for each id_num group with the lowest email_id. If the id_num group already has the Flag field set for one it will ignore it.
i have following table "vehicle_data" :
ID ALERT_TYPE VALUE
58 2 1
58 1 1
104 1 1
104 2 1
Here alert_type = 2 is for GPS value and alert_type=1 is for engine_value .
so if alert_type=2 and its value is =1 then it means its value is correct.
when alert_type=2 and its value is =0 then it means its value is wrong.
same for alert_type=1
so now here i want the following output:
ID gps engine_value
58 1 1
104 1 1
how can i perform this query??
You can do it like this.
SELECT ID
,CASE WHEN [ALERT_TYPE]=2 and [value ]=1 THEN 1 ELSE 0 END as gps
,CASE WHEN [ALERT_TYPE]=1 and [value ]=1 THEN 1 ELSE 0 END as engine
FROM vehicle_data
SELECT ID, alert_type=2 AS gps, alert_type=1 AS [engine] FROM vehicle_data WHERE value=1;
EDITED to account for your explanation of VALUE.
Schema
CREATE TABLE table3 (id int, ALERT_TYPE int)
INSERT table3 VALUES (58, 1), (58, 2), (104, 1), (104, 2)
Query
SELECT *
FROM (
SELECT ID
,ROW_NUMBER() OVER (
PARTITION BY id ORDER BY id
) AS row_num
,gps = CASE
WHEN ALERT_TYPE = 2
THEN 1
ELSE 0
END
,engine = CASE
WHEN ALERT_TYPE = 1
THEN 1
ELSE 0
END
FROM table3
) a
WHERE a.row_num = 1
Output
ID gps engine
58 1 0
104 0 1
One possible way using subqueries :
select
Ids.ID
, gps.VALUE 'gps'
, engine_value.VALUE 'engine_value'
from (select distinct ID from vehicle_data) Ids
left join
(select ID, VALUE from vehicle_data where ALERT_TYPE = 2) gps
on gps.ID = Ids.ID
left join
(select ID, VALUE from vehicle_data where ALERT_TYPE = 1) engine_value
on engine_value.ID = Ids.ID
[SQL Fiddle demo]
I hope this should work for you,
Select ID,sum(gps) as gps ,sum(engine) as engine from
(SELECT ID
,CASE WHEN [ALERT_TYPE]=2 and [value ]=1 THEN 1 ELSE 0 END as gps
,CASE WHEN [ALERT_TYPE]=1 and [value ]=1 THEN 1 ELSE 0 END as engine
FROM vehicle_data
)a
group by id
select x.id,x.alert_type as GPS,x.value as engine_value from (
select ID,alert_type,value,ROW_NUMBER() over (partition by id order by alert_type ) as Rnk from mytable
)x
where Rnk=1
Please check this query in SQL :
create table mytable (id int, alert_type int, value int);
insert into mytable (id, alert_type, value)
values (58, 2, 1),
(58, 1, 1),
(104, 1, 1),
(104, 2, 1);
SELECT distinct ID
,(select count (id) from mytable mt where mt.id=mytable.id and mt.[ALERT_TYPE]=2 and mt.[value ]=1) as gps
,(select count (id) from mytable mt where mt.id=mytable.id and mt.[ALERT_TYPE]=1 and mt.[value ]=1) as engine
FROM mytable

I have a query that returns among others a Record Status column. The record status column has several values like: "Active", "Deleted", etc ...
I need to order the results by "Active", then "Deleted", then etc ...
I am currently creating CTEs to bring each set of records then UNION ALL. Is there a better and dynamic way of getting the query done?
Thank you,
you can use CASE on here
ORDER BY CASE WHEN Status = 'Active' THEN 0 ELSE 1 END ASC
but if you have more values for status and you want to sort Active then DELETE
ORDER BY CASE WHEN Status = 'Active' THEN 0
WHEN Status = 'Deleted' THEN 1
ELSE 2
END ASC
For more status values, you can do this:
WITH StatusOrders
AS
(
SELECT StatusOrderID, StatusName
FROM (VALUES(1, 'Active'),
(2, 'Deleted'),
...
n, 'last status')) AS Statuses(StatusOrderID, StatusName)
)
SELECT *
FROM YourTable t
INNER JOIN StatusOrders s ON t.StatusName = s.StatusName
ORDER BY s.StatusOrderID;
WITH
cteRiskStatus
AS
(
SELECT RiskStatusID, RiskStatusName
FROM (VALUES(1, 'Active'),
(2, 'Draft'),
(3, 'Occured'),
(4, 'Escalated'),
(5, 'Closed'),
(6, 'Expired'),
(7, 'Deleted')) AS RiskStatuses(RiskStatusID, RiskStatusName)
)
SELECT * FROM cteRiskStatus
Thanks
