I have a table with CostCenter_ID (int) and a second table with Process_ID (int).
I'd like to combine the results of both tables so that each cost center ID is assigned to all process IDs, like so:
|CostCenterID | ProcessID |
---------------------------
| 1 | 1 |
| 1 | 2 |
| 1 | 3 |
| 2 | 1 |
| 2 | 2 |
| 2 | 3 |
| 3 | 1 |
| 3 | 2 |
| 3 | 3 |
I've done it before but I'm drawing a blank. I've tried this:
SELECT CostCenter_ID,NULL FROM dbo.Cost_Centers
UNION ALL
SELECT NULL,Process_ID FROM dbo.Processes
which returns this:
|CostCenterID | ProcessID |
---------------------------
| 1 | NULL |
| NULL | 1 |
| NULL | 2 |
| NULL | 3 |
Try:
select a.CostCenterID, b.ProcessID
from table1 a
cross join table2 b
or:
select a.CostCenterID, b.ProcessID
from table1 a
,table2 b
NB: cross join is the better method as it makes it clearer to the reader what your intentions are.

I have a table like this in MS SQL SERVER
+------+------+
| ID | Cust |
+------+------+
| 1 | A |
| 1 | A |
| 1 | B |
| 1 | B |
| 2 | A |
| 2 | A |
| 2 | A |
| 2 | B |
| 3 | A |
| 3 | B |
| 3 | B |
| 3 | C |
| 3 | C |
+------+------+
I don't know the values in column "Cust" and I want to return all rows where the value of "Cust" appears multiple times and where at least one of the "ID" values is "1".
Like this:
+------+------+
| ID | Cust |
+------+------+
| 1 | A |
| 1 | A |
| 1 | B |
| 1 | B |
| 2 | A |
| 2 | A |
| 2 | A |
| 2 | B |
| 3 | A |
| 3 | B |
| 3 | B |
+------+------+
Any ideas? I can't find it.
You may use COUNT window function as the following:
SELECT ID, Cust
FROM
(
SELECT ID, Cust,
COUNT(*) OVER (PARTITION BY Cust) cn,
COUNT(CASE WHEN ID=1 THEN 1 END) OVER (PARTITION BY Cust) cn2
FROM table_name
) T
WHERE cn>1 AND cn2>0
ORDER BY ID, Cust
COUNT(*) OVER (PARTITION BY Cust) to check if the value of "Cust" appears multiple times.
COUNT(CASE WHEN ID=1 THEN 1 END) OVER (PARTITION BY Cust) to check that at least one of the "ID" values is "1".
See a demo.
this is an initial table (this is just a part of a larger table where Article ID's can vary), database is MS Sql.
-----------------------------------
|ArticleID | GroupID |
-----------------------------------
| 1 | NULL |
-----------------------------------
| 2 | NULL |
-----------------------------------
| 3 | NULL |
-----------------------------------
| 4 | NULL |
-----------------------------------
Set of rows that should be entered for each ArticleID looks something like this:
------------------------
| GroupID |
------------------------
| A |
------------------------
| B |
------------------------
| C |
------------------------
| D |
------------------------
Result table should look something like this:
-----------------------------------
|ArticleID | GroupID |
-----------------------------------
| 1 | NULL |
-----------------------------------
| 1 | A |
-----------------------------------
| 1 | B |
-----------------------------------
| 1 | C |
-----------------------------------
| 1 | D |
-----------------------------------
| 2 | NULL |
-----------------------------------
| 2 | A |
-----------------------------------
| 2 | B |
-----------------------------------
| 2 | C |
-----------------------------------
| 2 | D |
-----------------------------------
| 3 | NULL |
-----------------------------------
| 3 | A |
-----------------------------------
| 3 | B |
-----------------------------------
| 3 | C |
-----------------------------------
| 3 | D |
-----------------------------------
| 4 | NULL |
-----------------------------------
| 4 | A |
-----------------------------------
| 4 | B |
-----------------------------------
| 4 | C |
-----------------------------------
| 4 | D |
-----------------------------------
Any suggestion how to insert it efficiently?
Thanks a lot for you suggestion.

This is a cross join between two sets.
with a as (
select * from(values (1),(2),(3),(4))v(ArticleId)
), g as (
select * from(values (null),('A'),('B'),('C'),('D'))v(GroupId)
)
select *
from a cross join g;
To insert into the original table you could do:
with g as (select * from(values('A'),('B'),('C'),('D'))v(GroupId))
insert into t
select t.ArticleId, g.GroupId
from t cross join g;
See Example Fiddle
I have 3 tables. The link between the first and the second table is REQ_ID and the link between the second and the third table is ENC_ID. There is no direct link between the first and the third table.
INS_RCPT
+----+--------+------+----------+
| ID | REQ_ID | CURR | RCPT_AMT |
+----+--------+------+----------+
| 1 | 1 | USD | 100 |
| 2 | 2 | USD | 200 |
| 3 | 3 | USD | 300 |
+----+--------+------+----------+
ENC_LOG
+----+--------+--------+-------------+
| ID | REQ_ID | ENC_ID | ENC_LOG_AMT |
+----+--------+--------+-------------+
| 1 | 1 | 1 | 20 |
| 2 | 1 | 2 | 50 |
| 3 | 1 | 3 | 30 |
| 4 | 2 | 4 | 20 |
+----+--------+--------+-------------+
ENC_RCPT
+----+--------+--------------+
| ID | ENC_ID | ENC_RCPT_AMT |
+----+--------+--------------+
| 1 | 1 | 10 |
| 2 | 1 | 10 |
| 3 | 2 | 15 |
| 4 | 2 | 25 |
| 5 | 2 | 10 |
| 6 | 3 | 12 |
| 7 | 3 | 18 |
| 8 | 4 | 10 |
+----+--------+--------------+
I would like to have output as follows:
+----+--------+------+----------+-------------+--------------+
| ID | REQ_ID | CURR | RCPT_AMT | ENC_LOG_AMT | ENC_RCPT_AMT |
+----+--------+------+----------+-------------+--------------+
| 1 | 1 | USD | 100 | 100 | 100 |
| 2 | 2 | USD | 200 | 20 | 10 |
| 3 | 3 | USD | 300 | 0 | 0 |

I am using SQL Server to write this query. Any help is appreciated.
One approach would be to join the first table to two subqueries which compute the sums separately:
SELECT
ir.ID,
ir.REQ_ID,
ir.CURR,
ir.RCPT_AMT,
el.ENC_LOG_AMT,
er.ENC_RCPT_AMT
FROM INS_RCPT ir
LEFT JOIN
(
SELECT REQ_ID, SUM(ENC_LOG_AMT) AS ENC_LOG_AMT
FROM ENC_LOG
GROUP BY REQ_ID
) el
ON ir.REQ_ID = el.REQ_ID
LEFT JOIN
(
SELECT t1.REQ_ID, SUM(t2.ENC_RCPT_AMT) AS ENC_RCPT_AMT
FROM ENC_LOG t1
INNER JOIN ENC_RCPT t2 ON t1.ENC_ID = t2.ENC_ID
GROUP BY t1.REQ_ID
) er
ON ir.REQ_ID = er.REQ_ID
Demo
Note that your question includes a curve ball. The second subquery needs to return aggregates of the receipt table by REQ_ID, even though this field does not appear in that table. As a result, we actually need to join ENC_LOG to ENC_RCPT in that subquery, and then aggregate by REQ_ID.
You can try the below query. Also change the join from left to inner as per your requirement.
select a.id,a.req_id,a.curr,sum(a.rcpt_amt) rcpt_amt,sum(a.enc_log_amt) enc_log_amt,sum(c.enc_rcpt_amt) enc_rcpt_amt
from
(
select a.id id ,a.req_id req_id ,a.curr curr,sum(rcpt_amt) as rcpt_amt,sum(enc_log_amt) as enc_log_amt
from ins_rcpt a
left join enc_log b
on a.req_id=b.req_id
group by id,req_id,curr
) a
left join enc_rcpt c
on a.enc_id = c.enc_id
group by id,req_id,curr;
I have 3 tables as shown:
Video
+----+--------+-----------+
| id | name | videoSize |
+----+--------+-----------+
| 1 | video1 | 1MB |
| 2 | video2 | 2MB |
| 3 | video3 | 3MB |
+----+--------+-----------+
Survey
+----+---------+-----------+
| id | name | questions |
+----+---------+-----------+
| 1 | survey1 | 1 |
| 2 | survey2 | 2 |
| 3 | survey3 | 3 |
+----+---------+-----------+
Sequence
+----+---------+-----------+----------+
| id | videoId | surveyId | sequence |
+----+---------+-----------+----------+
| 1 | null | 1 | 1 |
| 2 | 2 | null | 2 |
| 3 | null | 3 | 3 |
+----+---------+-----------+----------+
I would like to query Sequence and join on both of video and survey tables and merge common columns without specifying the column names (in this case name) like this:
Query Result:
+----+---------+-----------+----------+---------+-----------+-----------+
| id | videoId | surveyId | sequence | name | videoSize | questions |
+----+---------+-----------+----------+---------+-----------+-----------+
| 1 | null | 1 | 1 | survey1 | null | 1 |
| 2 | 2 | null | 2 | video2 | 2MB | null |
| 3 | null | 3 | 3 | survey3 | null | 3 |
+----+---------+-----------+----------+---------+-----------+-----------+
Is this possible?
BTW the below sql doesn't work as it doesn't merge on the name field:
SELECT * FROM "Sequence"
LEFT JOIN "Survey" ON "Survey"."id" = "Sequence"."surveyId"
LEFT JOIN "Video" ON "Video"."id" = "Sequence"."videoId"
This query will show what you want:
select
s.*,
coalesce(y.name, v.name) as name, -- picks the right column
v.videoSize,
y.questions
from sequence s
left join survey y on y.id = s.surveyId
left join video v on v.id = s.videoId
However, the SQL standard requires you to name the columns you want. The only exception being * as shown above.
I thought I could figure this out but I am having a lot of issues.I have 3 Tables, Table1, Table2, and Table3. These tables where designed by someone else and I have to work with them. They were not designed to be used the way they are used today.
The bottom line is I need to be able to enter an Item_No, this will always exist in Table2. And if the Item_No can also be found in Table 3, could be multiple times or none, and there can be times where I can find it 5 times in Table2 and only 3 times in Table3. If it is in Table3 it will also be in Table1.
So, using the Item_No i can find on Table2, return the Order_qty's associated with those rows. Then using the if exist getting Table1.ID where Table1.ID = Table3.ID WHERE Table3.Item_No = Table2.Item_No
I came up with the following, it does not give me errors but simply stops code execution during a C# fill. I had it working for finding the Item_No on Table3 and returning what it finds, I have ONLY changed this line of code since so I KNOW this is the issue.
Here is what I could come up with that is not working:
SELECT Table1.ID,
Table2.Order_Qty As [Qty of Full Order], Table2.Item_No As [Set No]
FROM Table2
LEFT JOIN Table3
ON Table2.Item_No = Table3.Item_No
AND Table2.Order_No = Table3.Order_No
LEFT JOIN Table1
ON Table1.Order_No = Table2.Order_No
AND Table1.ID = Table3.ID
WHERE Table2.Item_No = #m_strUserEnteredSeachValue
ORDER BY Table2.Order_No DESC

A pragmatic answer to a problem like this is to split it into a couple of queries. Query Table #2 first, and then based on that result set, run additional queries into #1 or #3.
Another angle is to query on Table #2 and use subqueries to reach-out-there into Table #1 or Table #3 to fetch data you need.
Try this:
declare #m_strUserEnteredSeachValue varchar(10) = '1234567893';
with a as
(
select
Order_No, Item_No, Customer_Item_Name
from
Table2
UNION
select
Order_No, Item_No, Customer_Item_Name
from
Table3
)
select
a.Order_No,
a.Item_No,
a.Customer_Item_Name,
Table3.Sub_Order_No,
Table1.Sub_Order_Contact
from
a
left join
Table3
on
Table3.Order_No=a.Order_No
and Table3.Item_No=a.Item_No
and Table3.Customer_Item_Name=a.Customer_Item_Name
left join
Table1
on
Table1.Sub_Order_No = Table3.Sub_Order_No
where
#m_strUserEnteredSeachValue = a.Customer_Item_Name
order by
a.Item_No, Table3.Sub_Order_No

I have no idea if this is what you are trying to arrive at or not, since it's difficult to understand from you question. All I know that this query gives the dataset that you put in OP.
