Where clause in COUNT function and joining two queries

Question

I have a table that I am trying to count the number of course passed, and also list the modules passed as well.
the first problem I am having is what to put in the where variable , so that its not specific to a customer(I can use the query below for a particular customer and a particular course)but I will like a generic query where the result will be distinct in terms
of user and course like the one below
select FirstName,LastName,CourseTitle,Noofmodules, count (Coursecompleted) as modulescompleted from EStudentsprogress where Coursecompleted = '1'and EmailAddress = '[email protected]'
and CourseTitle = 'Microsoft MOS 2010 EXCEL' Group by FirstName, LastName, CourseTitle, Noofmodules ;
How can i make it list the result as above, whereby i dont specify the email address or course title(trying to get the result for all the clients )
. Also I have a query that list the courses that is passed by the customer, I will like the column with the list of courses passed be added to the result above, but as a column for each course.
select FirstName,LastName,CourseTitle, EmailAddress, CourseModule as coursepassed from EStudentsprogress where coursecompleted =1
cheers

Answer 1

Do you mean this?
select FirstName,
LastName,
CourseTitle,
Noofmodules,
count (Coursecompleted) as modulescompleted,
STUFF((SELECT ',' + CourseTitle
FROM EStudentsprogress
WHERE FirstName = e.FirstName
AND LastName = e.LastName
WHERE Coursecompleted = '1'
FOR XML PATH('')),1,1,'') AS CoursesCompleted
from EStudentsprogress e
where Coursecompleted = '1'
Group by FirstName, LastName, CourseTitle, Noofmodules ;
If not please provide some sample data and explain the output you want

I AM HAVING Incorrect syntax near the keyword 'WHERE'. 
It was a typo
try this
select FirstName,
LastName,
CourseTitle,
Noofmodules,
count (Coursecompleted) as modulescompleted,
STUFF((SELECT ',' + CourseTitle
FROM EStudentsprogress
WHERE FirstName = e.FirstName
AND LastName = e.LastName
AND Coursecompleted = '1'
FOR XML PATH('')),1,1,'') AS CoursesCompleted
from EStudentsprogress e
where Coursecompleted = '1'
Group by FirstName, LastName, CourseTitle, Noofmodules ;

its populating all the result for a particular customer, so i added another clause to  it and it worked
select FirstName,
LastName,
CourseTitle,
Noofmodules, 
count (Coursecompleted) as modulescompleted,
STUFF((SELECT ','  + CourseTitle
FROM EStudentsprogress 
WHERE FirstName = e.FirstName
AND LastName = e.LastName
AND Coursecompleted = '1'
AND CourseTitle = e.CourseTitle
FOR XML PATH('')),1,1,'') AS CoursesCompleted
from EStudentsprogress e
where Coursecompleted = '1'
Group by FirstName, LastName, CourseTitle, Noofmodules ;
but the result of the column is long , so i tried to used the course module, which is a column with numbers, and i tried modifying the query , but i had Error converting data type varchar to float.( i checked and saw that stuff is for concatinating
strings) is there a way around it.
i used 
select FirstName,
LastName,
CourseModule,
CourseTitle,
Noofmodules, 
count (Coursecompleted) as modulescompleted,
STUFF((SELECT ','  + CourseModule
FROM EStudentsprogress 
WHERE FirstName = e.FirstName
AND LastName = e.LastName
AND Coursecompleted = '1'
AND CourseTitle = e.CourseTitle
FOR XML PATH('')),1,1,'') AS CoursesCompleted
from EStudentsprogress e
where Coursecompleted = '1'
Group by FirstName, LastName,CourseModule, CourseTitle, Noofmodules ;
