( object result_identifier )
dbx_fetch_row() returns a row on success, and
0 on failure (e.g. when no more rows are available).
When the DBX_RESULT_UNBUFFERED is not set in the
query, dbx_fetch_row() will fail as all rows have
already been fetched into the results data property.
As a side effect, the rows property of the query-result
object is incremented for each successful call to
The result_identifier parameter is the result
object returned by a call to dbx_query().
The returned object contains the same information as any row would have
in the dbx_query result data property, including
columns accessible by index or fieldname when the flags for dbx_guery
were set that way.
