ifx_fetch_row -- Get row as an associative array

Popis

array ifx_fetch_row ( resource result_id [, mixed position] )

Fetches one row of data from the result associated with the specified result identifier.

Subsequent calls to ifx_fetch_row() would return the next row in the result set, or FALSE if there are no more rows.

Seznam parametrů

result_id

result_id is a valid resultid returned by ifx_query() or ifx_prepare() (select type queries only!).

position

An optional parameter for a "fetch" operation on "scroll" cursors: NEXT, PREVIOUS, CURRENT, FIRST, LAST or a number. If you specify a number, an "absolute" row fetch is executed. This parameter is optional, and only valid for SCROLL cursors.

Návratové hodnoty

Returns an associative array that corresponds to the fetched row, or FALSE if there are no more rows.

Blob columns are returned as integer blob id values for use in ifx_get_blob() unless you have used ifx_textasvarchar(1) or ifx_byteasvarchar(1), in which case blobs are returned as string values.
