db2_fetch_row
Opis
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.
Parametry
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.
Zwracane wartości
Returns TRUE if the requested row exists in the result set. Returns FALSE if the requested row does not exist in the result set.

Przykład 2. i5/OS recommended alternatives to db2_fetch_row/db2_result On i5/OS it is recommended that you use db2_fetch_both(), db2_fetch_array(), or db2_fetch_object() over db2_fetch_row()/db2_result(). In general db2_fetch_row()/db2_result() have more issues with various column types in EBCIDIC to ASCII translation, including possible truncation in DBCS applications. You may also find the performance of db2_fetch_both(), db2_fetch_array(), and db2_fetch_object() to be superior to db2_fetch_row()/db2_result().
