Question

I’m trying something like:

            using (var db = new Database(ConnectionString, DataProvider))
            {
                var spResult =
                    db.Execute("exec [cmtUpdateOrganization] @Id,@FullName",
                               new
                                   {
                                       organizatonData.Id,
                                       organizatonData.FullName
                                   }
                        );
                if (spResult == 0 || spResult == 1)
                    return true;
                return false;
            }

But it appears the spResult is always -1.

Although in the stored procedure, it definately returns 0. I validated with the same parameters on sql server itself.

Output parameters work fine, but that is not what i prefer to do as it involves changing a lot of stored procedures.

Answer 1

The Execute method in PetaPoco just calls the ExecuteNonQuery() method form the SqlCommand object.

Here is there reason why you are returning -1, which comes directly from MSDN.

Quoted from MSDN

You can use the ExecuteNonQuery to perform catalog operations (for
example, querying the structure of a database or creating database
objects such as tables), or to change the data in a database without
using a DataSet by executing UPDATE, INSERT, or DELETE statements.

Although the ExecuteNonQuery returns no rows, any output parameters or
return values mapped to parameters are populated with data.

For UPDATE, INSERT, and DELETE statements, the return value is the
number of rows affected by the command. When a trigger exists on a
table being inserted or updated, the return value includes the number
of rows affected by both the insert or update operation and the number
of rows affected by the trigger or triggers. For all other types of
statements, the return value is -1. If a rollback occurs, the return
value is also -1.
