Currently I have the following table in database dbo.test :
agentid | serv | func | com |
--------+------+------+-----|
ampg | 1 | 0 | 1 |
jrep | 0 | 0 | 1 |
ampg | 1 | 1 | 0 |
jrep | 1 | 0 | 1 |
Desired result:
agentid | serv | func | com |
--------+------+------+-----|
ampg | 2 | 1 | 1 |
jrep | 1 | 0 | 2 |
So it recognizes same agent id and combines into one row summing up the values of each other column. I will then present it in gridview in visual. Is it possible?
Thank you
Try this:
select agentid ,sum(serv) as [serv], sum(func) as [func], sum(com) as [com]
from tablename
group by agentid
SQL Group By:
http://www.w3schools.com/sql/sql_groupby.asp
select
agentid,
sum(serv) [sum_serv],
sum(func) [sum_func],
sum(com) [sum_com]
from [table]
group by agentid

I have a table where each row consists of an ID, date, variable values (eg. var1).
When there is a null value for var1 in a row, I want like to replace the null value with the most recent non-null value before that date for that ID. How can I do this quickly for a very large table?
So presume I start with this table:
+----+------------|-------+
| id |date | var1 |
+----+------------+-------+
| 1 |'01-01-2022'|55 |
| 2 |'01-01-2022'|12 |
| 3 |'01-01-2022'|45 |
| 1 |'01-02-2022'|Null |
| 2 |'01-02-2022'|Null |
| 3 |'01-02-2022'|20 |
| 1 |'01-03-2022'|15 |
| 2 |'01-03-2022'|Null |
| 3 |'01-03-2022'|Null |
| 1 |'01-04-2022'|Null |
| 2 |'01-04-2022'|77 |
+----+------------+-------+
Then I want this
+----+------------|-------+
| id |date | var1 |
+----+------------+-------+
| 1 |'01-01-2022'|55 |
| 2 |'01-01-2022'|12 |
| 3 |'01-01-2022'|45 |
| 1 |'01-02-2022'|55 |
| 2 |'01-02-2022'|12 |
| 3 |'01-02-2022'|20 |
| 1 |'01-03-2022'|15 |
| 2 |'01-03-2022'|12 |
| 3 |'01-03-2022'|20 |
| 1 |'01-04-2022'|15 |
| 2 |'01-04-2022'|77 |
+----+------------+-------+
cte suits perfect here
this snippets returns the rows with values, just an update query and thats all (will update my response).
WITH selectcte AS
(
SELECT * FROM testnulls where var1 is NOT NULL
)
SELECT t1A.id, t1A.date, ISNULL(t1A.var1,t1B.var1) varvalue
FROM selectcte t1A
OUTER APPLY (SELECT TOP 1 *
FROM selectcte
WHERE id = t1A.id AND date < t1A.date
AND var1 IS NOT NULL
ORDER BY id, date DESC) t1B

I have the following three tables:
Permission
| PermissionId | PermissionName |
+--------------+----------------+
| 1 | A |
| 2 | B |
| 3 | C |
| 100 | D |
Group
| GroupId | GroupLevel | GroupName |
+---------+------------+----------------------+
| 1 | 0 | System Administrator |
| 7 | 0 | Test Group 100 |
| 8 | 20 | Test Group 200 |
| 9 | 20 | test |
| 10 | 50 | TestGroup01 |
| 11 | 51 | TestUser02 |
| 12 | 52 | TestUser03 |
GroupPermission
| GroupPermissionId | FkGroupId | FkPermissionId |
+-------------------+-----------+----------------+
| 1 | 1 | 1 |
| 2 | 1 | 2 |
| 3 | 1 | 3 |
| 4 | 1 | 4 |
I need to insert records into GroupPermission table, if table Group, GroupLevel column have 0
then I need to take its GroupId and need to insert values to GroupPermission table as that particular id and 100.
In order to above sample table records, I need to insert the following two records to GroupPermission table,
| FkGroupId | FkPermissionId |
+-----------+----------------+
| 1 | 100 |
| 7 | 100 |
How can I do it
This question is not very clear and I can only assume the value 100 is a static value and that you don't actually have foreign keys as the names of the columns imply. Also, you really should avoid reserved words like "Group" for object names. It makes things more difficult and confusing.
The simple version of your insert might look like this.
insert GroupPermission
(
FkGroupId
, FkPermissionId
)
select g.GroupId
, 100
from [Group] g
where g.GroupLevel = 0
--EDIT--
Since you want to only insert those rows that don't already exist you can use NOT EXISTS like this.
select g.GroupId
, 100
from [Group] g
where g.GroupLevel = 0
AND NOT EXISTS
(
select *
from GroupPermission gp
where gp.FkGroupId = g.GroupId
and g.FkPermissionId = 100
)
Or you could use a left join like this.
select g.GroupId
, 100
from [Group] g
left join GroupPermission gp on gp.FkGroupId = g.GroupId
and gp.FkPermissionId = 100
where g.GroupLevel = 0
and gp.FkGroupId is null
Problem description
Let the tables C and V have those values
>> Table V <<
| UnID | BillID | ProductDesc | Value | ... |
| 1 | 1 | 'Orange Juice' | 3.05 | ... |
| 1 | 1 | 'Apple Juice' | 3.05 | ... |
| 1 | 2 | 'Pizza' | 12.05 | ... |
| 1 | 2 | 'Chocolates' | 9.98 | ... |
| 1 | 2 | 'Honey' | 15.98 | ... |
| 1 | 3 | 'Bread' | 3.98 | ... |
| 2 | 1 | 'Yogurt' | 8.55 | ... |
| 2 | 1 | 'Ice Cream' | 7.05 | ... |
| 2 | 1 | 'Beer' | 9.98 | ... |
| 2 | 2 | 'League of Legends RP' | 40.00 | ... |
>> Table C <<
| UnID | BillID | ClientName | ... |
| 1 | 1 | 'Alexander' | ... |
| 1 | 2 | 'Tom' | ... |
| 1 | 3 | 'Julia' | ... |
| 2 | 1 | 'Tom' | ... |
| 2 | 2 | 'Alexander' | ... |
Table C have the values of each product, which is associated with a bill number. Table V has the relationship between the client name and the bill number. However, the bill number has a counter that is dependent on the UnId, which is the store unity ID. That being said, each store has it`s own Bill number 1, number 2, etc. Also, the number of bills from each store are not equal.
Solution description
I'm trying to make select between the C left join V without sucess. Because each BillID is dependent on the UnID, I have to make the join considering the concatenation between those two columns.
I've used this script, but it gives me an error.
SELECT
SUM(C.Value),
V.ClientName
FROM
C
LEFT JOIN
V
ON
CONCAT(C.UnID, C.BillID) = CONCAT(V.UnID, V.BillID)
GROUP BY
V.ClientName
and SQL server returns me this 'CONCAT' is not a recognized built-in function name.
I'm using Microsoft SQL Server 2008 R2
Is the use of CONCAT wrong? Or is it the way I tried to SELECT? Could you give me a hand?
[OBS: The tables I've present you are just for the purpose of explaining my difficulties. That being said, if you find any errors in the explanation, please let me know to correct them.]
You should be joining on the equality of the UnID and BillID columns in the two tables:
SELECT
c.ClientName,
COALESCE(SUM(v.Value), 0) AS total
FROM C c
LEFT JOIN V v
ON c.UnID = v.UnID AND
c.BillID = v.BillID
GROUP BY
c.ClientName;
In theory you could try joining on CONCAT(UnID, BillID). However, you could run into problems. For example, UnID = 1 with BillID = 23 would, concatenated together, be the same as UnID = 12 and BillID = 3.
Note: We wrap the sum with COALESCE, because should a given client have no entries in the V table, the sum would return NULL, which we then replace with zero.
concat is only available in sql server 2012.
Here's one option.
SELECT
SUM(C.Value),
V.ClientName
FROM
C
LEFT JOIN
V
ON
cast(C.UnID as varchar(100)) + cast(C.BillID as varchar(100)) = cast(V.UnID as varchar(100)) + cast(V.BillID as varchar(100))
GROUP BY
V.ClientName
I have a situation where I need to query from a 2 table in MS Access.
I'm new to this SQL access.
Table: UserInfo
===================
| UserID | Gender |
===================
| K01 | M |
| K02 | M |
| K03 | F |
| K04 | M |
===================
Table: OrderInfo
===================================
| OrderID | Type | UserID_FK |
===================================
| 1 | Food | K01 |
| 2 | Food | K01 |
| 3 | Toolkit | K02 |
| 4 | Food | K04 |
| 5 | Toolkit | K03 |
===================================
The question is:
I want to query so the result produce this table, how can I do it in MS Access?
I'm thinking that I should do a subquery but I don't know how to do it.
Table: Summary
================================================================
| UserID | Gender | CountOfToolkit | CountOfFood | TotalCount |
================================================================
| K01 | M | 0 | 2 | 2 |
| K02 | M | 1 | 0 | 1 |
| K03 | F | 1 | 0 | 1 |
| K04 | M | 0 | 1 | 1 |
================================================================
First, Type is a reserved word in MS Access.
You should avoid using reserved words.
Having said that, try this:
SELECT a.UserID, a.Gender, SUM(IIF(b.[Type] ='Food',1,0)) AS CountOfFood, SUM(IIF(b.[Type] ='Toolkit',1,0)) AS CountOfToolkit, COUNT(*) AS TotalCount
FROM UserInfo a INNER JOIN OrderInfo b ON a.UserId = b.UserID_FK
GROUP BY a.UserID, a.Gender
This crosstab query doesn't rely on having just Food & Toolkit as your types - it will count any new types you add.
The NZ wrapped around the Count(sType) ensures the 0 values are shown, while the CLNG ensures it's still treated as a number rather than text.
You could just use Count(sType) AS CountOfType.
TRANSFORM CLNG(NZ(Count(sType),0)) AS CountOfType
SELECT UserID
,Gender
,COUNT(sType) AS TotalCount
FROM UserInfo LEFT JOIN OrderInfo ON UserInfo.UserID = OrderInfo.UserID_FK
GROUP BY UserID, Gender
PIVOT sType
I am trying my hardest to get a list of the most recent rows by date in a DB2 file. The file has no unique id, so I am trying to get the entries by matching a set of columns. I need DESCGA most importantly as that changes often. When it does they keep another row for historical reasons.
SELECT B.COGA, B.COMSUBGA, B.ACCTGA, B.PRFXGA, B.DESCGA
FROM mylib.myfile B
WHERE
(
SELECT COUNT(*)
FROM
(
SELECT A.COGA,A.COMSUBGA,A.ACCTGA,A.PRFXGA,MAX(A.DATEGA) AS EDATE
FROM mylib.myfile A
GROUP BY A.COGA, A.COMSUBGA, A.ACCTGA, A.PRFXGA
) T
WHERE
(B.ACCTGA = T.ACCTGA AND
B.COGA = T.COGA AND
B.COMSUBGA = T.COMSUBGA AND
B.PRFXGA = T.PRFXGA AND
B.DATEGA = T.EDATE)
) > 1
This is what I am trying and so far I get 0 results.
If I remove
B.ACCTGA = T.ACCTGA AND
It will return results (of course wrong).
I am using ODBC in VS 2013 to structure this query.
I have a table with the following
| a | b | descri | date |
-----------------------------
| 1 | 0 | string | 20140102 |
| 2 | 1 | string | 20140103 |
| 1 | 1 | string | 20140101 |
| 1 | 1 | string | 20150101 |
| 1 | 0 | string | 20150102 |
| 2 | 1 | string | 20150103 |
| 1 | 1 | string | 20150103 |
and i need
| 1 | 0 | string | 20150102 |
| 2 | 1 | string | 20150103 |
| 1 | 1 | string | 20150103 |
You can use row_number():
select t.*
from (select t.*,
row_number() over (partition by a, b order by date desc) as seqnum
from mylib.myfile t
) t
where seqnum = 1;
