How to know if every queries executed successfully in loop?

Question

Suppose I have executed an update query in loop using PetaPoco like,

foreach (var obj in mainObject) {
   db.Execute("update Table set Column = @0 where C1=@1 and C2 =@2", Column1, obj.data1, obj.data2);
}

How to know if each of these queries has been executed successfully ?

Answer 1

Usually PetaPoco returns 1 OR greater if a single query is executed successfully or means if any rows are affected and 0 if failed.

With this scenario you can trace those values by adding that in the loop, like:

List<int> checkSuccess = new List<int>(); //To trace the value returned by execute query

foreach (var obj in mainObject) {
    int updated = db.Execute("update Table set Column = @0 where C1=@1 and C2 =@2", Column1, obj.data1, obj.data2);
    checkSuccess.Add(updated);
}

if (checkSuccess.All(i => i >= 1))
{
    //Your every queries has been updated successfully
}
