db2_fetch_row

Description

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.

Parameters

Return Values

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

Examples

Example 1. Iterating through a result set The following example demonstrates how to iterate through a result set with db2_fetch_row() and retrieve columns from the result set with db2_result(). <?php $sql = 'SELECT name, breed FROM animals WHERE weight < ?'; $stmt = db2_prepare($conn, $sql); db2_execute($stmt, array(10)); while (db2_fetch_row($stmt)) {     $name = db2_result($stmt, 0);     $breed = db2_result($stmt, 1);     print "$name $breed"; } ?> The above example will output: cat Pook gold fish Bubbles budgerigar Gizmo goat Rickety Ride

Example 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(). <?php   $conn = db2_connect("","","");   $sql = 'SELECT SPECIFIC_SCHEMA, SPECIFIC_NAME, ROUTINE_SCHEMA, ROUTINE_NAME, ROUTINE_TYPE, ROUTINE_CREATED, ROUTINE_BODY, IN_PARMS, OUT_PARMS, INOUT_PARMS, PARAMETER_STYLE, EXTERNAL_NAME, EXTERNAL_LANGUAGE FROM QSYS2.SYSROUTINES FETCH FIRST 2 ROWS ONLY';   $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE));   while ($row = db2_fetch_both($stmt)){     echo "<br>db2_fetch_both {$row['SPECIFIC_NAME']} {$row['ROUTINE_CREATED']} {$row[5]}";   }   $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE));   while ($row = db2_fetch_array($stmt)){     echo "<br>db2_fetch_array {$row[1]}  {$row[5]}";   }   $stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE));   while ($row = db2_fetch_object($stmt)){     echo "<br>db2_fetch_object {$row->SPECIFIC_NAME} {$row->ROUTINE_CREATED}";   }   db2_close($conn); ?> The above example will output: db2_fetch_both MATCH_ANIMAL 2006-08-25-17.10.23.775000 2006-08-25-17.10.23.775000 db2_fetch_both MULTIRESULTS 2006-10-17-10.11.05.308000 2006-10-17-10.11.05.308000 db2_fetch_array MATCH_ANIMAL 2006-08-25-17.10.23.775000 db2_fetch_array MULTIRESULTS 2006-10-17-10.11.05.308000 db2_fetch_object MATCH_ANIMAL 2006-08-25-17.10.23.775000 db2_fetch_object MULTIRESULTS 2006-10-17-10.11.05.308000
