Entity Framework 7 FromSql stored procedure return value

.net c# entity-framework-core

Question

I am trying to return a value using the new FromSql command in Entity Framework 7. My stored procedure returns a value of 0 if all goes well and 1 if an error occurs.

Using FromSql with DbSet we can for example do

_dbContext.ExampleEntity.FromSql('someSproc', 'param')

How will you get the scalar return value of 0 or 1 from this?

Looks like stored procedure support is still on the backlog.

Here's an example extension method you can call using _dbContext.ExecuteStoredProcedure("someSproc", "param");.

public static class DbContextExtension 
{
    public static int ExecuteStoredProcedure(this DbContext context, string name, string parameter)
    {
        var command = context.Database.GetDbConnection().CreateCommand();
        command.CommandType = CommandType.StoredProcedure;
        command.CommandText = name;
        var param = command.CreateParameter();
        param.ParameterName = "@p0";
        param.Value = parameter;
        command.Parameters.Add(param);
        return (int)command.ExecuteScalar();
    }
}
