Updating existing rows in a table requires to run the UPDATE statement with a WHERE clause to identify the row. The following sample script updates one row with two new values:

<?php
  $con = odbc_connect('FYI_SQL_SERVER','sa','FYIcenter');

  $sql = "UPDATE fyi_links SET notes='Nice site.', counts=8"
    . " WHERE id = 102";
  $res = odbc_exec($con, $sql);
  if (!$res) {
    print("SQL statement failed with error:\n");
    print(odbc_error($con).": ".odbc_errormsg($con)."\n");
  } else {
    $number_of_rows = odbc_num_rows($res);
    print("$number_of_rows rows updated.\n");
  }

  odbc_close($con);
?>

If you run this script, you will get something like this:

1 rows updated.
