Question

I wrote a simple (test) procedure and it returns only 1 row, why is that?

SELECT *
FROM service

The procedure executes fine, just the result shown contains only first row instead of all table records.

Answer 1

If you got the last row each time. Then may be your code is something like that,

$result = mysql_query("SELECT * FROM service");
while($row = mysql_fetch_array($result))
{
  $user=$row['Username'];  //assume you have a column named Username
}

echo $user . "<br>";

But it should be like below, then you can get all data.

$result = mysql_query("SELECT * FROM service");
while($row = mysql_fetch_array($result))
{
  $user=$row['Username'];  //assume you have a column named Username
  echo $user . "<br>";
}
