Issue writing Count SQL query and displaying results

Question

I am having an issue converting this query into a Count query, is anyone able to help. I basically want to count the number of records returned for this date, and ideally show it in a table that says Database Name and then total count. EG In this example would be Test then 6

SELECT
    test.dbo.OrderedDocuments.UserDocumentID, 
    OrderedDocuments.OrderGroupID, OrderGroups.TimePlaced 
FROM
    OrderedDocuments 
INNER JOIN 
    OrderGroups ON OrderedDocuments.OrderGroupID = OrderGroups.OrderGroupID
WHERE 
    OrderGroups.TimePlaced > '2018-05-17'

Answer 1

If, you want to display count then use count() function :

For instance :

SELECT count(*) Total_count
FROM  OrderedDocuments 
INNER JOIN OrderGroups 
           ON OrderedDocuments.OrderGroupID = OrderGroups.OrderGroupID
WHERE OrderGroups.TimePlaced >'2018-05-17';

If, you want to get departmental count then use GROUP BY clause to get departmental count

Answer 2

From my understanding (assuming UserDocumentID is the field you want to see the counts of) you would want to do this:

SELECT od.UserDocumentID, COUNT(*) as Total
FROM  OrderedDocuments od
INNER JOIN OrderGroups og
   ON od.OrderGroupID = og.OrderGroupID
WHERE og.TimePlaced >'2018-05-17'
GROUP BY od.UserDocumentID
