GROUP By and Having count in LinQ

[Paul]

Hi

How can i do this:

SELECT Name, COUNT(*) AS Num
FROM Table1
GROUP BY Name
HAVING COUNT(*)>1

What would be the equivalent:
var lst=from cust in datacontext.customer ....

Any idea?

Thanks

Don't have the code, but subset the count(*) > 1 and join it to your
main query to filter that way. Grouping is fairly easy.

group x by x into y

for example. This link hits the grouping:

I saw a good workaround for having (to subset) yesterday, but I cannot
find it in my history today ... at least not yet. If I find it, I will
post. I know I found it through a google search, however.

Peace and Grace,
