In the tab-delimeted input file below I am trying to use awk to update the value in $2 if TYPE=ins in bold, by adding the value of

db2_fetch_both
DB2_FETCH_BOTH(3) 1 DB2_FETCH_BOTH(3)db2_fetch_both - Returns an array, indexed by both column name and position, representing a row in a result setSYNOPSIS
array db2_fetch_both (resource $stmt, [int $row_number = -1])
DESCRIPTION
Returns an array, indexed by both column name and position, representing a row in a result set. Note that the row returned by
db2_fetch_both(3) requires more memory than the single-indexed arrays returned by db2_fetch_assoc(3) or db2_fetch_array(3).
PARAMETERS
o $stmt
- A valid stmt resource containing a result set.
o $row_number
- Requests a specific 1-indexed row from the result set. Passing this parameter results in a PHP warning if the result set uses a
forward-only cursor.
RETURN VALUES
Returns an associative array with column values indexed by both the column name and 0-indexed column number. The array represents the next
or requested row in the result set. Returns FALSE if there are no rows left in the result set, or if the row requested by $row_number does
not exist in the result set.
EXAMPLES
Example #1
Iterating through a forward-only cursor
If you call db2_fetch_both(3) without a specific row number, it automatically retrieves the next row in the result set. The follow-
ing example accesses columns in the returned array by both column name and by numeric index.
<?php
$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$stmt = db2_prepare($conn, $sql);
$result = db2_execute($stmt);
while ($row = db2_fetch_both($stmt)) {
printf ("%-5d %-16s %-32s %10s
",
$row['ID'], $row[0], $row['BREED'], $row[3]);
}
?>
The above example will output:
0 Pook cat 3.20
5 Rickety Ride goat 9.70
2 Smarty horse 350.00
Example #2
Retrieving specific rows with db2_fetch_both(3) from a scrollable cursor
If your result set uses a scrollable cursor, you can call db2_fetch_both(3) with a specific row number. The following example
retrieves every other row in the result set, starting with the second row.
<?php
$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$result = db2_exec($stmt, $sql, array('cursor' => DB2_SCROLLABLE));
$i=2;
while ($row = db2_fetch_both($result, $i)) {
printf ("%-5d %-16s %-32s %10s
",
$row[0], $row['NAME'], $row[2], $row['WEIGHT']);
$i = $i + 2;
}
?>
The above example will output:
0 Pook cat 3.20
5 Rickety Ride goat 9.70
2 Smarty horse 350.00
