db2_fetch_row

(no version information, might be only in CVS)db2_fetch_row -- Sets the result set pointer to the next row or requested row

Описание

bool db2_fetch_row (resource stmt [, int row_number])

Use db2_fetch_row() to iterate through a result set, or to point to a specific row in a result set if you requested a scrollable cursor.

To retrieve individual fields from the result set, call the db2_result() function.

Rather than calling db2_fetch_row() and db2_result(), most applications will call one of db2_fetch_assoc(), db2_fetch_both(), or db2_fetch_array() to advance the result set pointer and return a complete row as an array.

Список параметров

stmt

A valid stmt resource.

row_number

With scrollable cursors, you can request a specific row number in the result set. Row numbering is 1-indexed.

Возвращаемые значения

Returns TRUE if the requested row exists in the result set. Returns FALSE if the requested row does not exist in the result set.
