I can't quite explain it properly, hence the awful title.
As an example, I would have a query that shows customer complaints, of a certain type, and the dates since those complaints. Something like the following:
select * from( select c.firstname, c.lastname , max(ont.date1) as "LastDate",
DATEDIFF(DAY, MAX(ont.Date1), SYSDATETIME()) AS "Days"
from [ComplaintInfo] ci
inner join [OrderNotes] ont on ont.orderid = ci.orderid
inner join [Customers] c on c.custid = ci.custid
right outer join [CustLive] cl on ont.custidl = cl.custidl
where (ci.typeofcomp = '2' or ci.typeofcomp = '3')
and (ont.answertype <> '2' and ont.answertype <> '3' and ont.answertype <>'4'
group by c.lastname, c.firstname
) Sub
where Days >= 5
order by Days, sub.lastname asc
This would give something like
John | Smith | 2020-06-03T13:00:00 | 1
Terry | Jones | 2020-05-04T:04:00:00 | 30
However, although I'm wanting typeoforder to NOT be 2 or 3, and I don't want them to be included in my result set, I would like to know whether or not there have been any orders of those types. So, if for example
John | Smith |2020-06-03T13:00:00 | 1 | Yes
Terry | Jones | 2020-05-04-04:00:00 | 30 | No
Could just be asking a stupid question, but need to know. Thanks.
You can remove the condition from the where clause and use a conditional expression:
select
c.firstname,
c.lastname,
max(ont.date1) as LastDate
datediff(day, max(ont.date1), sysdatetime()) as days,
max(case when ci.typeofcomp = 2 or ci.typeofcomp = 3 then 'Yes' else 'No' end) hasTypeOfComp_2_Or_3
from [ComplaintInfo] ci
inner join [OrderNotes] ont on ont.orderid = ci.orderid
inner join [Customers] c on c.custid = ci.custid
right outer join [CustLive] cl on ont.custidl = cl.custidl
where ont.answertype <> 2 and ont.answertype <> 3 and ont.answertype <> 4
group by c.lastname, c.firstname
Notes:
I removed the single quotes around the numbers - since they look like numbers, I assumed that they are stored as such, in which case you want to compare them against literal numbers (if that's not the case, you can put the quotes back)
I am suspicious about the right outer join: is this really what you want? If not, just use an inner join

I am trying to get the highest value based off of another column.
SELECT DISTINCT
AppDetailVehicleValuation.AppID,
VehicleValuationOption.Description,
MAX (VehicleValuationOptionValueType.Value)
FROM

INNER JOIN VehicleValuationOption
ON AppDetailVehicleValuation.ValuationID = VehicleValuationOption.ValuationID
INNER JOIN VehicleValuationOptionValueType
ON VehicleValuationOption.ValuationOptionID = VehicleValuationOptionValueType.ValuationOptionID
WHERE
(VehicleValuationOption.IsSelected LIKE '1')
AND (VehicleValuationOption.IsSystemOption LIKE '1')
What I have is this
AppID | Description | Value
999 Beats Audio 425.00
999 Beats Audio 475.00

999 Power Str. 750.00
this is what I need
AppID | Description | Value
999 Beats Audio 475.00
999 Power Str. | 750.00
You are just missing a GROUP BY clause in your query:
SELECT
AppDetailVehicleValuation.AppID,
VehicleValuationOption.Description,
MAX (VehicleValuationOptionValueType.Value)
FROM
AppDetailVehicleValuation
INNER JOIN VehicleValuationOption
ON AppDetailVehicleValuation.ValuationID = VehicleValuationOption.ValuationID
INNER JOIN VehicleValuationOptionValueType
ON VehicleValuationOption.ValuationOptionID = VehicleValuationOptionValueType.ValuationOptionID
WHERE
(VehicleValuationOption.IsSelected LIKE '1')
AND (VehicleValuationOption.IsSystemOption LIKE '1')
GROUP BY AppDetailVehicleValuation.AppID, VehicleValuationOption.Description
You can simply do this:
SELECT
t.AppId,
t.Description,
max(t.Value)
FROM mytable t
GROUP BY t.description, t.AppId
This is too long for a comment.
Glad you found an answer that works with the GROUP BY. I would suggest you start using aliases in your queries. It can quickly and easily turn a wall of text into something fairly easy to see what is going on. You might end with something along these lines.
SELECT advv.AppID
, vvo.Description
, MaxValue = MAX(vvot.Value)
FROM AppDetailVehicleValuation advv
INNER JOIN VehicleValuationOption vvo ON advv.ValuationID = vvo.ValuationID
INNER JOIN VehicleValuationOptionValueType vvot ON vvo.ValuationOptionID = vvot.ValuationOptionID
WHERE vvo.IsSelected = '1'
AND vvo.IsSystemOption = '1'
group by advv.AppID
, vvo.Description
I have the following query;
What I get is tickets information. I use self-join to obtain the requester and the assignee in the same row:
SELECT z.id AS TICKET, z.name AS Subject, reqs.name AS Requester, techs.name AS Assignee,
e.name AS Entity,DATE_FORMAT(tt.date,'%y%-%m%-%d') AS DATE,
DATE_FORMAT(tt.date,'%T') AS HOUR,
CASE WHEN z.priority = 6 THEN 'Mayor' WHEN z.priority = 5 THEN 'Muy urgente' WHEN z.priority = 4 THEN 'Urgente'WHEN z.priority = 3 THEN 'Mediana' WHEN z.priority = 2 THEN 'Baja' WHEN z.priority =1 THEN 'Muy baja' END AS Priority,
c.name AS Category, i.name AS Department
FROM glpi_tickets_users tureq
JOIN glpi_tickets_users tutech ON tureq.tickets_id = tutech.tickets_id
JOIN glpi_users AS reqs ON tureq.users_id = reqs.id
JOIN glpi_users AS techs ON tutech.users_id = techs.id
JOIN glpi_tickets z ON z.id = tureq.tickets_id
LEFT OUTER JOIN glpi_tickettasks tt ON z.id = tt.tickets_id
LEFT JOIN glpi_itilcategories i ON z.itilcategories_id = i.id
LEFT JOIN glpi_usercategories c ON c.id = reqs.usercategories_id
INNER JOIN glpi_entities e ON z.entities_id = e.id
WHERE (tureq.id < tutech.id AND tureq.type < tutech.type) OR
(tureq.id < tutech.id AND tureq.users_id = tutech.users_id) OR
(tureq.id = tutech.id AND tureq.users_id = tutech.users_id)
The problem is that I get something like that:
1 Report jdoe jdoe Development 16-06-07 11:56:17 Mediana Software Mkt
1 Report jdoe fwilson Development 16-06-07 11:56:17 Mediana Software MKt
1 Report fwilson fwilson Development 16-06-07 11:56:17 Mediana Software Mkt
2 Task11 gwilliams gwilliams Ops 16-06-08 12:00:00 ALTA Hardware Def
3 Task12 gwilliams gwilliams Ops 16-06-08 12:01:00 ALTA Hardware Def
I don't want first and third row because is a CROSS JOIN result. Second row is OK, because jdoe is a requester and fwilson an assignee.
The problem is that sometimes requester and assignee are the same, eg: he creates a ticket for a task that himself will do. For example, 4th and 5th rows are OK.
So, how should I do to make a difference for those distinct cases, i.e.: I need to include:
tureq.id = tech.id AND req.users_id = tech.users.id
BUT NOT IF ALREADY EXISTS
tureq.id = tech.id AND req.users_id <> tech.users_id
Update
The main problem is that a user can assign to himself a ticket:
SELECT * from glpi_tickets_users WHERE type = 2 GROUP BY tickets_id HAVING COUNT(users_id)<2 limit 3;
+----+------------+----------+------+------------------+-------------------+
| id | tickets_id | users_id | type | use_notification | alternative_email |
+----+------------+----------+------+------------------+-------------------+
| 1 | 2 | 12 | 2 | 1 | NULL |
| 3 | 6 | 13 | 2 | 1 | NULL |
| 7 | 8 | 14 | 2 | 1 | NULL |
+----+------------+----------+------+------------------+-------------------+
Update 2:
It was a human mistake. The problem was really not about self-assigned tickets. Rather it was either that some tickets had not Requester or had Requester but still had not any resolver assigned.
I've found
As there are always the two types per ticket you are interested in, you can simply select the according records, so as to get requester and assignee per ticket.
select
t.id as ticket,
t.name as subject,
requester.name as requester,
assignee.name as assignee,
e.name as entity,
date_format(tt.date,'%y%-%m%-%d') as date,
date_format(tt.date,'%T') as hour,
case t.priority
when 6 then 'Mayor'
when 5 then 'Muy urgente'
when 4 then 'Urgente'
when 3 then 'Mediana'
when 2 then 'Baja'
when 1 then 'Muy baja'
end as priority,
uc.name as category,
ic.name as department
from glpi_tickets t
join glpi_entities e on e.id = t.entities_id
join
(
select tu.tickets_id, u.name, u.usercategories_id
from glpi_tickets_users tu
join glpi_users u on u.id = users_id
where tu.type = 1
) requester on requester.tickets_id = t.id
join
(
select tu.tickets_id, u.name
from glpi_tickets_users tu
join glpi_users u on u.id = users_id
where tu.type = 2
) assignee on assignee.tickets_id = t.id
left join glpi_itilcategories ic on ic.id = t.itilcategories_id
left join glpi_usercategories uc on uc.id = requester.usercategories_id;
left outer join glpi_tickettasks tt on tt.tickets_id = t.id
The only thing I wonder is: There can be several ticket tasks per ticket. So what do you want to do then? Have one line per ticket task in your results? This is what the query does. Only, it looks queer that your result rows don't contain any information on the tasks except for the dates, so you may have many, many lines with the same data, only with different dates. So maybe, you'd rather want the first or last date per ticket. To get the last date per ticket, you'd replace the last line in the query with:
left outer join
(
select tickets_id, max(date) as date
from glpi_tickettasks
group by tickets_id
) tt on tt.tickets_id = t.id
And you probably want to add an ORDER BY clause.
you need to add more qualifiers to your joins for example
JOIN glpi_tickets_users tutech ON tureq.tickets_id = tutech.tickets_id and tutech.type = 2
I am using a prebuilt program so I am unable to directly edit the SQL, I can only edit snippets of it. The problem I am having is that the code is printing out the customer code for as many cases that customer has. For example, if a customer has 57 cases, it will print the customer code 57 times instead of just showing it once such as Customer Code 4 Cases 57 etc.
I was reading that you may not be able to use a Unique or Distinct function with the OVER command but I am not sure how else to make the sum work without it. Here is my code:
SET NOCOUNT ON;
DECLARE #ShowZeros nVarChar(4000);
SET #ShowZeros = 'N';
SELECT
SUM ([IC_ProductLots].[Available_Alt]) OVER(PARTITION BY [AR_Customers]. [CustomerCode]) AS [Cases]
, IC_Products.UnitOfMeasure_Alt
, SUM([IC_ProductLots].[Available_Stk]) OVER(PARTITION BY [AR_Customers]. [CustomerCode]) AS [Total Stock]
, IC_Products.UnitOfMeasure_Stk
, IC_Products.Description1
, IC_Products.ProductCode
, AR_Customers.Name
, AR_Customers.CustomerCode
FROM
((( DC_Transactions
INNER JOIN
AR_Customers ON DC_Transactions.CustomerKey = AR_Customers.CustomerKey)
INNER JOIN
IC_ProductLots ON DC_Transactions.LotKey = IC_ProductLots.LotKey)
INNER JOIN
IC_Products ON DC_Transactions.ProductKey = IC_Products.ProductKey)
WHERE
(IC_Products.ProductCode = ' 515070') AND
((CASE WHEN #ShowZeros = 'Y' or #ShowZeros = 'YES' THEN 1 ELSE
(ISNULL([IC_ProductLots].[Available_Stk],0))
END) > 0)
ORDER BY
IC_Products.ProductCode
, AR_Customers.CustomerCode
, AR_Customers.Name
Output should look similar to below:
Cases | U/M | Total Stock | Description | Cust Name | Cust Code
-----------------------------------------------------------------
57 | CS | 1779.45 | Food | Restaurant | 2
4 | CS | 120 | Dough | Bakery | 44
Currently it prints out 57 lines for customer code 2 and 4 lines for customer code 44, displaying the same information for each customer code.
The following seems to be more or less what you want. You say you can only partly edit your query, but well, you need the GROUP BY clause to say which records you want (i.e. one record per product and customer), so this is what mainly needs be done. Then you cannot use an OVER clause, as the aggregation group is given by GROUP BY already. I have made more changes for readability. See what edits you can do.
select
sum(l.available_alt) as cases
, p.unitofmeasure_alt
, sum(l.available_stk) as [total stock]
, p.unitofmeasure_stk
, p.description1
, p.productcode
, c.name
, c.customercode
from dc_transactions t
inner join ar_customers c on t.customerkey = c.customerkey
inner join ic_productlots l on t.lotkey = l.lotkey
inner join ic_products p on t.productkey = p.productkey
where p.productcode = ' 515070'
and (#showzeros in ('Y', 'YES') or l.available_stk > 0)
group by p.productcode, c.customercode
, p.unitofmeasure_alt, p.unitofmeasure_stk, p.description1, c.name
order by p.productcode, c.customercode;
I am actually creating a crystal reports v12 (2008) report but can't find the method, using Crystal, to extract the following. I thought if someone might answer in SQL language, I could piece it together.
2 Tables: hbmast, ddmast
SELECT hbmast.custno, hbmast.id, ddmast.name, ddmast.status
WHERE hbmast.custno = ddmast.custno
GROUP BY hbmast.id
pseudo code::show all hbmast values that have ddmast.status = '2'
Sample output:
J0001, 111222, PAUL JONES, 1
111222, PAUL JONES, 2
111222, PAUL JONES, 1
K0001, 555333, PETER KING, 3
555333, PETER KING, 1
I would like to have Paul show on the report with all child records but Peter should not be returned on the report since he has no child records with '2' for ddmast.status field.
Thanks for the help
I think you're looking for this:
select hb.custno, hb.id, dd.name, dd.status from hbmast hb
join ddmast dd on hb.custno = dd.custno
where hb.custno in (
select custno from ddmast
where status = '2'
)
Let me know if this returns your expected result.
The way to achieve this in Crystal would be to have your hb and dd tables then a second alias of the dd table.
So you would filter your dd alias table where status = 2 then join to your hb table and back to your dd table (not the alias). The SQL would end up looking like:
select hb.custno, hb.id, dd.name, dd.status from hbmast hb
inner join ddmast dd on hb.custno = dd.custno
inner join ddmast dd2 on hb.custno = dd2.custno
where dd2.status = '2'
Andomar makes a valid point about duplicate records appearing if there is more than 1 record per group with a status of 2. If that is the case you can either group by primary key and show row information at group footer level OR use a sql expression with a subquery in your selection formula instead of the double join method.
SQL Expression: (select count(*) from ddmast where custno = "hbmast.custno" and status = '2')
Then record selection expert: {%sqlexpression} > 0
And a different way to get the same...
SELECT hb.custno, hb.id, dd.name, dd.status
FROM hbmast hb
INNER join ddmast dd
on hb.custno = dd.custno
INNER JOIN DDMAST2 DD2
on DD2.custNo = HB.custNo
AND DD2.Status='2'
i have a table campaign which has details of campaign mails sent.
campaign_table: campaign_id campaign_name flag
1 test1 1
2 test2 1
3 test3 0
another table campaign activity which has details of campaign activities.
campaign_activity: campaign_id is_clicked is_opened
1 0 1
1 1 0
2 0 1
2 1 0
I want to get all campaigns with flag value 3 and the number of is_clicked columns with value 1 and number of columns with is_opened value 1 in a single query.
ie. campaign_id campaign_name numberofclicks numberofopens
1 test1 1 1
2 test2 1 1
I did this using sub-query with the query:
select c.campaign_id,c.campaign_name,
(SELECT count(campaign_id) from campaign_activity WHERE campaign_id=c.id AND is_clicked=1) as numberofclicks,
(SELECT count(campaign_id) from campaign_activity WHERE campaign_id=c.id AND is_clicked=1) as numberofopens
FROM
campaign c
WHERE c.flag=1
But people say that using sub-queries are not a good coding convention and you have to use join instead of sub-queries. But i don't know how to get the same result using join. I consulted with some of my colleagues and they are saying that its not possible to use join in this situation. Is it possible to get the same result using joins? if yes, please tell me how.
This should do the trick. Substitute INNER JOIN for LEFT OUTER JOIN if you want to include campaigns which have no activity.
SELECT
c.Campaign_ID
, c.Campaign_Name
, SUM(CASE WHEN a.Is_Clicked = 1 THEN 1 ELSE 0 END) AS NumberOfClicks
, SUM(CASE WHEN a.Is_Opened = 1 THEN 1 ELSE 0 END) AS NumberOfOpens
FROM
dbo.Campaign c
INNER JOIN
dbo.Campaign_Activity a
ON a.Campaign_ID = c.Campaign_ID
GROUP BY
c.Campaign_ID
, c.Campaign_Name
Assuming is_clicked and is_opened are only ever 1 or 0, this should work:
select c.campaign_id, c.campaign_name, sum(d.is_clicked), sum(d.is_opened)
from campaign c inner join campaign_activity d
on c.campaign_id = d.campaign_id
where c.flag = 1
group by c.campaign_id, c.campaign_name
No sub-queries.
Hmm. Is what you want as simple as this? I'm not sure I'm reading the question right...
SELECT
campaign_table.campaign_id, SUM(is_clicked), SUM(is_opened)
FROM
campaign_table
INNER JOIN campaign_activity ON campaign_table.campaign_id = campaign_activity.campaign_id
WHERE
campaign_table.flag = 1
GROUP BY
campaign_table.campaign_id
Note that with an INNER JOIN here, you won't see campaigns where there's nothing corresponding in the campaign_activity table. In that circumstance, you should use a LEFT JOIN, and convert NULL to 0 in the SUM, e.g. SUM(IFNULL(is_clicked, 0)).
I suppose this should do it :
select * from campaign_table inner join campaign_activity on campaign_table.id = campaign_activity.id where campaign_table.flag = 3 and campaign_activity.is_clicked = 1 and campaign_activity.is_opened = 1
Attn : this is not tested in a live situation
The SQL in it's simplest form and most robust form is this: (formatted for readability)
SELECT
campaign_table.campaign_ID, campaign_table.campaign_name, Sum(campaign_activity.is_clicked) AS numberofclicks, Sum(campaign_activity.is_open) AS numberofopens
FROM
campaign_table INNER JOIN campaign_activity ON campaign_table.campaign_ID = campaign_activity.campaign_ID
GROUP BY
campaign_table.campaign_ID, campaign_table.campaign_name, campaign_table.flag
HAVING
campaign_table.flag=1;
