spec_meta_get_rows_affected

Value

dbGetRowsAffected() returns a scalar number (integer or numeric), the number of rows affected by a data manipulation statement issued with dbSendStatement(). The value is available directly after the call and does not change after calling dbFetch(). NA_integer_ or NA_numeric_ are allowed if the number of rows affected is not known.

For queries issued with dbSendQuery(), zero is returned before and after the call to dbFetch(). NA values are not allowed.

Failure modes

Attempting to get the rows affected for a result set cleared with dbClearResult() gives an error.
