SQL without a WHERE that uses a key column - php

Question

My script is quitting on SQL calls that should not have an issue. One of the queries that is failing to update is:
UPDATE dist_comp.private_schools SET mail_address = '1351 Royalty Dr', city = 'Alabaster', state = 'AL',zip_code = 35007,phone = '2056633973' WHERE school_name = 'Kingwood Christian School' AND city = 'Alabaster'
When I run the same query in MySQL workbench, I get
Error Code: 1175. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column To disable safe mode, toggle the option in Preferences -> SQL Queries and reconnect.
Is this the reason why my script is quitting?
<?php
require_once('connect.php');
function schoolInfo($school_name,$city){
$data = array();
$counter = 0;
$handle = fopen("k12privateschools_loc_0813.csv","r") or exit('doesnt work');
fgetcsv($handle) or exit('fgetcsv issue');
while( ($line = fgetcsv($handle)) !== false) {
$data[] = $line;
///echo ("Does schoolname and city match: " . addslashes($data[$counter][2]). ":" . $school_name . " ; " . addslashes($data[$counter][4]). ":" . $city . "\n");

$sql2 = mysqli_query($con,"SELECT school_name,city FROM dist_comp.private_schools") or exit('query issue second');
while($row = mysqli_fetch_array($sql2)){ //this line is making it take a really long time
$school_name= addslashes($row['school_name']);
$city = addslashes($row['city']);
schoolInfo($school_name,$city);
}//end while fetch array
//}
echo "Import finished";
?>

Answer 1

Try to disable safe update using this line before your query :
mysqli_query($con,"SET sql_safe_updates=0");
Or use :
$query="SET sql_safe_updates=0";
$query.= "UPDATE dist_comp.private_schools SET
mail_address = '".$mail_address."',
city = '".$city."',
state = '".$state."';";
mysqli_multi_query($con,$query);
or in MySQL WorkBench:
Edit -> Preferences -> SQL Queries
Uncheck Forbid UPDATE and DELETE statements without a WHERE clause
(safe updates)
Query --> Reconnect to Server

Answer 2

$query = 'SET SQL_SAFE_UPDATES=0;';
$query .= 'custom query here;';
$query .= 'SET SQL_SAFE_UPDATES=1;';
