Hi :
From a crystal report i get a list of employee firstnames as a string
into my store procedure. Why is it comming this way ? hmmmmmm it's a
question for me too.
ex: "e1,e2,e3"
here are my tables
tblProjects
ProjectId
1
2
3
tblEmployee
employeeId FirstName
1 e1
2 e2
3 e3
tblProjectsToEmployee
ProjectId employeeId
1 1
1 2
1 3
2 1
2 2
3 1
3 2
3 3
4 1
4 3
i need to find out the project ids all 3 of these employees worked on.
so the out put i need is
projectId
1
3
How can i get it ????????????
now i can use replace command to format it to a OR clause or AND
clause
SET @string= 'employeeId =' + '''' + REPLACE('e1,e2,e3',',',''' OR
employeeId = ''') + ''''
some thing like this.
OR clause will give me all 4 projects.
in('e1','e2','e3') will give me all 4 projects.
of cause AND command will not give me any.
other method i tried was adding the employee table 3 times into the
same SQL string and doing some thing like
WHERE (empTable1.Firstname ='e1' AND (empTable1.Firstname
in('e2','e3'))
AND (empTable2.Firstname ='e2' AND (empTable1.Firstname in('e1','e3'))
AND ...
and goes alone. this gives me some what i needed. but it's a very
messy way of doing it, because i get a comma seperated string
parameter i have to construct the sql string on the fly.
any help or direction on this matter would greatly appreciated.
thanks

Hi Eric,
The first step would be to convert the comma-delimited list of employees
to a temp table. SQL Server MVP Erland Sommarskog has a whole web page
devoted to various techniques to accomplish this. Check it out at http://www.sommarskog.se/arrays-in-sql.html, pick one of the techniques
and implement it. For the rest of this message, I'll assume that the
employees you are looking for are not in a comma-delimited list anymore,
but in the temp table #Employees, column EmployeeID.
i need to find out the project ids all 3 of these employees worked on. so the out put i need is
projectId 1 3 How can i get it ????????????
(snip)
This is called "relational division". The standard solution is
SELECT p.ProjectID
FROM Projects AS p
INNER JOIN ProjectsToEmployee AS pe
ON pe.ProjectID = p.ProjectID
INNER JOIN #Employees AS e
ON e.EmployeeID = pe.EmployeeID
GROUP BY p.ProjectID
HAVING COUNT(*) = (SELECT COUNT(*) FROM #Employees)
Best, Hugo

You can try this, I know database experts won't like this solution but
it works :)
SELECT ProjectId
FROM (SELECT tblProjects.ProjectId,SUM(tblEmployee.sadrzajid) as sum_all
FROM tblProjects
INNER JOIN tblProjectsToEmployee
ON tblProjects.ProjectId = tblProjectsToEmployee.ProjectId
INNER JOIN tblEmployee
ON tblProjectsToEmployee.employeeId = tblEmployee.employeeId
GROUP BY tblProjects.ProjectId) AS complet
WHERE (complet.sum_all = (SELECT SUM(employeeId)
FROM tblEmployee))

lapsus, sorry
FROM tblProjects INNER JOIN tblProjectsToEmployee ON tblProjects.ProjectId = tblProjectsToEmployee.ProjectId INNER JOIN tblEmployee ON tblProjectsToEmployee.employeeId = tblEmployee.employeeId GROUP BY tblProjects.ProjectId) AS complet WHERE (complet.sum_all = (SELECT SUM(employeeId) FROM tblEmployee)) Josko This thread has been closed and replies have been disabled.
