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().
