Question

I have a SP which I want to call from linq. The SP have 5 parameters but i only want to pass/need to 2 of them.

how would I call the SP as when i go to add the parameters in code it wont build as it want all 5.

Answer 1

You'd have something like this:

MyDbDataContext db = new MyDbDataContext();

db.MyStoredProc(customerID, "sometext", null, null, null);

Success/failure would depend on the SQL statements inside your sproc dealing with nulls on those last 3 parameters.

Answer 2

Another option is to drag the stored proc into your DBML a second time and delete the parameters you don't want to pass in.

Answer 3

overload the sproc call.

I dont have it in front of me but you'd goto your DataAccessName.cs file and create a method name with the same signature

auto gen'd sproc method signature:

void sp_sproc(int a, int b, int c, int d, int e);

you'd make this in your DataAccessName.cs file

void sp_sproc(int a, int b)
{
    this.sp_sproc(a,b,0,0,0);
}

if the params are nullable, like so

void sp_sproc(int? a, int? b, int? c, int? d, int? e);

then you could do

void sp_sproc(int a, int b)
{
    this.sp_sproc(a,b,null,null,null);
}
