DB2_FETCH_ROW(3) 1 DB2_FETCH_ROW(3)
db2_fetch_row - Sets the result set pointer to the next row or requested row
SYNOPSIS
bool db2_fetch_row (resource $stmt, [int $row_number])
DESCRIPTION
Use db2_fetch_row(3) 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(3) function.
Rather than calling db2_fetch_row(3) and db2_result(3), most applications will call one of db2_fetch_assoc(3), db2_fetch_both(3), or
db2_fetch_array(3) to advance the result set pointer and return a complete row as an array.
PARAMETERS
o $stmt
- A valid stmt resource.
o $row_number
- With scrollable cursors, you can request a specific row number in the result set. Row numbering is 1-indexed.
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(3) and retrieve columns from the result
set with db2_result(3).
<?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(3), db2_fetch_array(3), or db2_fetch_object(3) over
db2_fetch_row(3)/db2_result(3). In general db2_fetch_row(3)/db2_result(3) 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(3),
db2_fetch_array(3), and db2_fetch_object(3) to be superior to db2_fetch_row(3)/db2_result(3).
<?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:
