Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.
The number of columns in the result set is returned in an associative array element $array["count"]. Because some of the result columns may be empty, the count() function can not be used on the result row returned by sesam_fetch_row().
result_id is a valid result id returned by sesam_query() (select type queries only!).
whence is an optional parameter for a fetch operation on "scrollable" cursors, which can be set to the following predefined constants:
Table 1. Valid values for "whence" parameter
|0||SESAM_SEEK_NEXT||read sequentially (after fetch, the internal default is set to SESAM_SEEK_NEXT)|
|1||SESAM_SEEK_PRIOR||read sequentially backwards (after fetch, the internal default is set to SESAM_SEEK_PRIOR)|
|2||SESAM_SEEK_FIRST||rewind to first row (after fetch, the default is set to SESAM_SEEK_NEXT)|
|3||SESAM_SEEK_LAST||seek to last row (after fetch, the default is set to SESAM_SEEK_PRIOR)|
|4||SESAM_SEEK_ABSOLUTE||seek to absolute row number given as offset (Zero-based. After fetch, the internal default is set to SESAM_SEEK_ABSOLUTE, and the internal offset value is auto-incremented)|
|5||SESAM_SEEK_RELATIVE||seek relative to current scroll position, where offset can be a positive or negative offset value.|
When using "scrollable" cursors, the cursor can be freely positioned on the result set. If the whence parameter is omitted, the global default values for the scrolling type (initialized to: SESAM_SEEK_NEXT, and settable by sesam_seek_row()) are used. If whence is supplied, its value replaces the global default.
offset is an optional parameter which is only evaluated (and required) if whence is either SESAM_SEEK_RELATIVE or SESAM_SEEK_ABSOLUTE. This parameter is only valid for "scrollable" cursors.
sesam_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array (indexed by values between 0 and $array["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.
Subsequent calls to sesam_fetch_row() would return the next (or prior, or n'th next/prior, depending on the scroll attributes) row in the result set, or FALSE if there are no more rows.
