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.
