Retrieve SQL statement from MySQL and process in PHP - php

Question

I have successfully saved a number of SQL UPDATE statements to MySQL and now I want to retrieve them and have PHP process them. The code is below.
When I echo $query I get the correct SQL statements from the DB, but then when I try to process them, I get an error Warning: mysqli_query() [function.mysqli-query]: Empty query
It makes no sense to me and is driving me nuts! Do I have to do something else to $query so PHP can process it?
$num_rows = mysqli_num_rows($resultSQL);
if ($num_rows > 0)
{
while ($row = mysqli_fetch_array($resultSQL))
{
$strSQLupd[] = $row['uSQL'];
}
foreach ($strSQLupd as $query) {
$resultSQLupd = mysqli_query($link,
$query
);
if (!$resultSQLupd)
{
$error = 'Error fetching data: ' . mysqli_error($link);
include 'error.html.php';
exit();
}
}
}

Answer 1

Are you setting the value of $link somewhere and is it required for what you're doing in this application? Also, remember that var_dump($varname); is always a helpful debugging tool.
foreach ($strSQLupd as $query) {
// put a var_dump below
var_dump($query);
$resultSQLupd = mysqli_query($query
);
if (!$resultSQLupd)
{
$error = 'Error fetching data: ' . mysqli_error($link);
include 'error.html.php';
exit();
}
}
Give this a shot and look at the query string dumped to the screen. It may be null which is what's producing your error.
