How to handle multiple ResultSets, each with multiple Rows?
The call to NextResult()
breaks the while loop.
Some of my SPs return multiple ResultSets. I'm handling these with NextResult()
but when I do and my SP only has a single ResultSet, I see the while loop with Read() finishes leaving me with only the first Row.
Without the call to NextResult()
I get all the rows for the first ResultSet but of course the second and subsequent ResultSets don't get processed?
using (IDataReader reader = storedProcedure.ExecuteReader(
CommandBehavior.CloseConnection, parameterNames as string[], arguments))
{
while (reader.Read())
{
ArrayList row = new ArrayList();
for (int j = 0; j < reader.FieldCount; ++j)
{
object rowValue = reader.GetValue(j);
row.Add(rowValue);
}
reader.NextResult();//next resultset, breaks out of the while
}
}
