How do I do the below using JOIN:
Select
id_pk, col1, col2,col
From table1 A
Where NOT EXISTS
(select 1 from table2 B
Where A.id_pk = B.id_pk
and A.col1 = B.col1
and A.col2 = B.col2
);
Here, join query cannot be simply used, as we know that both tables share their primary key id_pk, we could rather obtain the primary keys of those records which satisfy the conditions A.id_pk = B.id_pk (Equi-join), A.col1 = B.col1 and A.col2 = B.col2. And we can use this set of primary keys to obtain those records whose primary keys do not match using NOT IN operator. The join query is given as a sub-query, in this case.
Query:
SELECT
id_pk, col1, col2, col
FROM table1
WHERE id_pk NOT IN (
SELECT A.id_pk
FROM table1 A, table2 B
WHERE A.id_pk = B.id_pk
AND A.col1 = B.col1
AND A.col2 = B.col2
);

I am looking to do some querying on two partitions (different partition date) on BQ.
Table format is the following
crm_id, attribute#1, attribute#2,attribute#3
For the IDs that are common from week 1 and week 2, I want to see how many changed attribute#1, attribute#2 and attribute# 3
I started with the inner join using:
WITH t1 AS
(SELECT crm_id AS w1_crm
FROM `table`
WHERE DATE(_PARTITIONTIME) = "date1"
)
SELECT crm_id
FROM `table`
WHERE DATE(_PARTITIONTIME) = "date2"
INNER JOIN
t1
ON
w1_crm = crm_id
I am getting an error on the INNER JOIN
Try below
WITH t1 AS (
SELECT crm_id AS w1_crm
FROM `table`
WHERE DATE(_PARTITIONTIME) = "date1"
), t2 AS (
SELECT crm_id
FROM `table`
WHERE DATE(_PARTITIONTIME) = "date2"
)
SELECT crm_id
FROM t2
INNER JOIN t1
ON w1_crm = crm_id
I am working on sql server I have two tables and I need to return records from the left table which are not found in the right table for that I am using left join like below query,
select #MID=MID,#MName=Name,#PID=PID,#PName=PName,#DID=DID from #CompanyDataInfo where id=#MCount
insert into #temp SELECT Top(1) f.Name,f.PID,f.PName,v.* FROM #CompanyDataInfo f
left join Employee v on v.Id=f.ID and v.DID=f.DID
where v.Id =#MID and v.DId = #DId and v.PId = #PId and v.CId =#CId and DATE_TIME between DATEADD(minute,-555,GETDATE()) and GETDATE() order by DATE_TIME desc
Result should be all rows from #CompanyDataInfo table while no record found in Employee table for related ID, I googled and use "v.Id is null" but not getting expected result
Is there any solution greatly appriciable
Thanks In advance
Your query is not using left join in correct way. You are using your right table reference in where clause. I try to correct it below but I don't have full information about your table schema. Please try this-
select
#MID = MID,
#MName = Name,
#PID = PID,
#PName = PName,
#DID = DID
from #CompanyDataInfo
where id = #MCount
insert into #temp
select
f.Name,
f.PID,
f.PName,
v.*
from #CompanyDataInfo f
left join Employee v on v.Id=f.ID and v.DID=f.DID
where f.Id = #MID and
f.DId = #DId and
f.PId = #PId and
f.CId = #CId and
f.DATE_TIME between DATEADD(minute,-555,GETDATE()) and GETDATE() and
v.Id is null
order by f.DATE_TIME desc
Add ...and v.Id is null to your where clause.
I have two tables table1 and table2. Each table contains a column with itemPrice. I need to add the two columns together.
The SQL query below returns the correct SUM.
SELECT SUM(item1+ item2) FROM
(select SUM(t1.itemPrice) item1 from table1 t1 WHERE t1.userid=='jonh') tableA
CROSS JOIN
(select SUM(t2.itemPrice) item2 from table2 t2 WHERE t1.userid=='jonh') tableB
I am not been lazy but the above query has so many SUM functions that I don't know where to start to write LINQ queries.
Can anyone help?
Ceci,
Hopefully this will give you what you want...
from f in (
from x in ( from t1 in Table1
where t1.Userid.Equals("John")
select new { Userid = t1.Userid }
).Distinct()
select new { item1 = ( from z in Table1
where z.Userid.Equals("John")
select z.ItemPrice ).Sum() ??0 ,
item2 = ( from z in Table2
where z.Userid.Equals("John")
select z.ItemPrice ).Sum() ??0 }
) select new { total = f.item1 + f.item2 }
In the case where there are no records for "john" in one table, it will bring back a 0 and sum up the other tables.
hope this helps.
I have multiple tables in a join and every table has a column ID. So in the resultig join there are a lot of ID columns. How I can access a specific ID column with the criteria API?
ParameterExpression<A> idParam = criteriaBuilder.parameter(A.class, PARAM_NAME);
Subquery<B> sq = query.subquery(B.class);
Root<B> root = sq.from(B.class);
Join<C, D> joinTogether = root.join("memberX").join("memberY");
sq.select(root);
sq.where(criteriaBuilder.and(criteriaBuilder.equal(joinTogether.get("id"), idParam), criteriaBuilder.equal(parentQuery.get("id"), root.get("id"))));
The problem is, that in the resulting SQL contains
SELECT 1 FROM E t6, B t5, C t4, D t3 WHERE ((( = paramName) AND (t0.ID = t5.ID)) AND (((t6.memberZ = t5.ID) AND (t4.ID = t6.memberX)) AND (t3.ID = t4.memberY))))
The table E (t6) is an additional join table between table B and C, t0 is the reference to the parent query. Instead t3.id = :paramName EclipseLink creates nothing just before the first equal-sign (paramName is the content of the constant PARAM_NAME). My idea is, that the "id" column could reference all tables and EclipseLink can not decide, which table I mean.
How I can change that?
Thank you
André
I have three tables. I have to retrieve the data using Linq statement. My three table names are A,B,C. I connected join for connecting two tables A and B based on the id's like:
select ol, fN, LN, ci, co
from member
join details
on member_id = details_id
where details_id in
(select contacts_id from contacts where
contacts_id1 = 1 and contacts_usr_id = 1)
I am able to write the query up to the where condition, how can I write the query for the inner while condition?
you can try this:
var idlist = (from tbl in table3
where tbl.usr_id == 1 && tbl.contacts_id == 1
select tbl.contacts_id ).ToList();
var x = from A in table1
from B in table2 where A.user_id == B.user_id
&& idlist.Contains(A.user_id)
select new { a = A.a, b = A.b, c = A.c, d = B.d, e = B.e };
check and let me know if that work.
Try flipping the query upside down. How about the following:
var query =
from t3 in table3
where t3.user_id = 1 && t3.contacts_id = 1
join t2 in table2 on t3.contacts_id equals t2.usr_id
join t1 in table1 on t2.usr_id equals t1.userid
select new {t2.a, t2.b, t2.c, t1.d, t1.e};
