sesam_fetch_result
(PHP 3 CVS only)
sesam_fetch_result -- Return all or part of a query result
Description
mixed sesam_fetch_result ( string result_id [, int max_rows])
Returns a mixed array with the query result entries, optionally
limited to a maximum of max_rows rows. Note that both row
and column indexes are zero-based.
Table 1. Mixed result set returned by sesam_fetch_result()
Array Element Contents
int $arr["count"] number of columns in result
set (or zero if this was an "immediate" query)
int $arr["rows"] number of rows in result set
(between zero and max_rows)
bool $arr["truncated"] TRUE if the number of rows
was at least max_rows, FALSE otherwise. Note that even when
this is TRUE, the next sesam_fetch_result() call may return
zero rows because there are no more result entries.
mixed $arr[col][row] result data for all the fields at row(row)
and column(col), (where the integer index row is between
0 and $arr["rows"]-1, and col is between 0 and
$arr["count"]-1). Fields may be empty, so you
must check for the existence of a field by using the php
isset() function. The type of the returned fields depend
on the respective SQL type declared for its column (see
SESAM overview for the conversions applied). SESAM "multiple
fields" are "inlined" and treated like a
sequence of columns.
Note that the amount of memory used up by a large query
may be gigantic. Use the max_rows parameter to limit the
maximum number of rows returned, unless you are absolutely
sure that your result will not use up all available memory.
See also: sesam_fetch_row(), and sesam_field_array() to
check for "multiple fields". See the description
of the sesam_query() function for a complete example using
sesam_fetch_result().
