dbx_fetch_row — Fetches rows from a query-result that had the DBX_RESULT_UNBUFFERED flag set
Inhaltsverzeichnis |
Beschreibung
mixed dbx_fetch_row ( object $result_identifier )
dbx_fetch_row() fetches rows from a result identifier
that had the DBX_RESULT_UNBUFFERED flag set.
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
dbx_fetch_row().
Parameter-Liste
- result_identifier
- A result set returned by dbx_query().
Rückgabewerte
Returns an object on success that 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_query() were set
that way.
Upon failure, returns 0 (e.g. when no more rows are
available).
Beispiele
