Hi,

I have one table in that there are more than 300 records.
I am doing operation for each record using LINQ. But it gets hang.

C#

var qryCkeckClocked = (from a in
                                             context.sp1
                                         select a);
foreach (var scan in qryCkeckClocked)
                    
var stud = (from ***
}

This is my code.
I think the query excutes with no of iteration to SQL.
Please suggest me

That code fragment doesn't tell us very much: the second part won't even compile.
But what the first part does depends on what "context" is: if it's an IEmumerable such as a List, then it does nothing useful in practice!

300 records is nothing, you shouldn't even feel the time of execution without having some bad-a$$ computing within.

If you want to use join two table use Join function of LINQ instead of foreach. This query will create sql command like

VB

Select * from context.sp1

So instead of * you can select only desired table this will also reduce query execution time.
