Need help with switching field/column values
Hi all, I need some help on switching field/column values. For example I have a file name data.txt which contains:
a b
a b
a b
and I want to switch a and b and save it to the same file.
the file data.txt then will have:
b a
b a
b a
The problem is, well, I know how to switch field values in awk, but it's not gonna modify the file itself. I could just output the result to another file and change the file name, but now I want to modify the file data.txt directly. Is there any way to do it? And I would like to know if vi can do that. Thank you very much.

db2_result
DB2_RESULT(3) 1 DB2_RESULT(3)
db2_result - Returns a single column from a row in the result set
SYNOPSIS
mixed db2_result (resource $stmt, mixed $column)
DESCRIPTION
Use db2_result(3) to return the value of a specified column in the current row of a result set. You must call db2_fetch_row(3) before
calling db2_result(3) to set the location of the result set pointer.
PARAMETERS
o $stmt
- A valid stmt resource.
o $column
- Either an integer mapping to the 0-indexed field in the result set, or a string matching the name of the column.
RETURN VALUES
Returns the value of the requested field if the field exists in the result set. Returns NULL if the field does not exist, and issues a
warning.
EXAMPLES
Example #1
A db2_result(3) example
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, 'BREED');
print "$name $breed";
}
?>
The above example will output:
cat Pook
gold fish Bubbles
budgerigar Gizmo
goat Rickety Ride
