HTML Table not showing first record of PostgreSQL - php

Question

I've managed to fill an HTML table with user queries from PostgreSQL without problem, the thing is that when I make the Query on the PostgreSQL database directly it shows the complete records according to the Query but when I do it in my PHP and fill an HTML with it it doesn't show the first one
For example I have 500 records and I want them in DESC order
It should show:
500
499
498
...
But it shows:
499
498
497
...
So its 'jumping' the first record always, with every query I call
What could it be? Obviously I need all the records.
Here is the code I'm using to run the query($sql1) and $conexion is the connection to my postgresql db:
$rs =odbc_exec($conexion, $sql1);
$nr =odbc_result($rs, 1);
if(!empty($nr)){
print "

Your problem (as pointed out by #Sean in the comments) is that this line:
$nr =odbc_result($rs, 1);
is reading the first row from the result set and you are not outputting the data from that row. To work around this I would recommend an if ... do ... while structure:
if ($result = odbc_fetch_array($rs)) {
// output the table headers here
do {
// output the row data
} while ($result = odbc_fetch_array($rs));
}
else {
// no data to output
}
