DBIResult-class: DBIResult class

In DBI: R Database Interface

DBIResult class

Description

This virtual class describes the result and state of execution of a DBMS statement (any statement, query or non-query). The result set keeps track of whether the statement produces output how many rows were affected by the operation, how many rows have been fetched (if statement is a query), whether there are more rows to fetch, etc.

Implementation notes

Individual drivers are free to allow single or multiple active results per connection.

The default show method displays a summary of the query using other DBI generics.
