awk
Thank you for your reply.
The things is everytime the file that passed to awk is different.
So I don't know the exact number of columns.
But I only modify $1,$2. There might be over 10 fields after that.
It's really $0 - $1 - $2.
I need to write out any fields after $1 and $2.
Any hint?

maxdb_field_tell
MAXDB_FIELD_TELL(3) 1 MAXDB_FIELD_TELL(3)
maxdb_field_tell - Get current field offset of a result pointer
Procedural style
SYNOPSIS
int maxdb_field_tell (resource $result)
DESCRIPTION
Object oriented style
int$maxdb_result->current_field ()
Returns the position of the field cursor used for the last maxdb_fetch_field(3) call. This value can be used as an argument to
maxdb_field_seek(3).
RETURN VALUES
Returns current offset of field cursor.
EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = $maxdb->query($query)) {
/* Get field information for all columns */
while ($finfo = $result->fetch_field()) {
/* get fieldpointer offset */
$currentfield = $result->current_field;
printf("Column %d:
", $currentfield);
printf("Name: %s
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $finfo->type);
}
$result->close();
}
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = maxdb_query($link, $query)) {
/* Get field information for all fields */
while ($finfo = maxdb_fetch_field($result)) {
/* get fieldpointer offset */
$currentfield = maxdb_field_tell($result);
printf("Column %d:
", $currentfield);
printf("Name: %s
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $finfo->type);
}
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Column 1:
Name: NAME
Table:
max. Len: 10
Flags: -1
Type: 2
Column 2:
Name: CNO
Table:
max. Len: 4
Flags: -1
Type: 0
