I am trying to use 'cut' to get a line from my file. But it seems that 'cut' recongnizes TAB as default. My file uses space instead. So 'cut' doesn't work.
Anybody can tell me how to change the default from TAB to space ? Or how to transform a space-delimited file into tab-delimited file??... (2 Replies)
I have a file which contains 6 columns.
But I only need the first 3 columns. So I need to remove the last 3 columns. I checked 'cut' but it seems not working.
So is there a command that could remove certain columns from a file? :(

DB2_FETCH_ARRAY(3) 1 DB2_FETCH_ARRAY(3)db2_fetch_array - Returns an array, indexed by column position, representing a row in a result setSYNOPSIS
array db2_fetch_array (resource $stmt, [int $row_number = -1])
DESCRIPTION
Returns an array, indexed by column position, representing a row in a result set. The columns are 0-indexed.
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 a 0-indexed array with column values indexed by the column position representing 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_array(3) without a specific row number, it automatically retrieves the next row in the result set.
<?php
$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$stmt = db2_prepare($conn, $sql);
$result = db2_execute($stmt);
while ($row = db2_fetch_array($stmt)) {
printf ("%-5d %-16s %-32s %10s
",
$row[0], $row[1], $row[2], $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_array(3) from a scrollable cursor
If your result set uses a scrollable cursor, you can call db2_fetch_array(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_array($result, $i)) {
printf ("%-5d %-16s %-32s %10s
",
$row[0], $row[1], $row[2], $row[3]);
$i = $i + 2;
}
?>
The above example will output:
0 Pook cat 3.20
5 Rickety Ride goat 9.70
2 Smarty horse 350.00
