hop of those help? I'm not sure about the Response.Write part but I am sure that you create a SQLCommand but never actually execute it.
Did you forget to put a cmd.executeNonScalar() in there?

I hope this helps . You don't need to include the keyword "table" in your query. You can check the syntax of the update query here: http://www.w3schools.com/php/php_mysql_update.asp
It should look like this:
code :
UPDATE givi_user_sessions set givi_user_clientid='somevalue' where givi_user_id=2;

it helps some times I have a table that contains an oldid and an oldparid. I want to update the rows where row.oldpar = otherrow.oldid but I'm having a problem with my query. , Use join for it
code :
update 
    01_menu_main t1
    join 01_menu_main t2 on t2.oldid = t1.oldpar
set
    t1.parid = t2.newpar

this will help As Forbs stated, your UPDATE statement will not result in any changes since you are filtering based on "current_timestamp", which will be whatever time the query executes. What you need to do instead is pass an existing timestamp into your code so that it updates whatever existing record already has that as its iso_date.
See the example below for how you can change your code.
code :
//this is whatever your time is that you are looking for a record for
$isoDateDT = '2018-08-01 08:15:00';//human readable datetime
$isoDateTS = strtotime($isoDateDT);//unix timestamp
$result = "SELECT * FROM open_lab_report WHERE iso_date = $isoDateTS";
if(!mysqli_query($link, $result)) {
    $sql = "INSERT INTO open_lab_report (iso_date, lab_monitor, incidentReport) VALUES ($isoDateTS, '$lab_monitor', 1)";
} else {
    $sql = "UPDATE open_lab_report SET incidentReport = 1 WHERE iso_date = $isoDateTS";
}

if(!mysqli_query($link, $sql)) {
    echo "Query failed, code: " . mysqli_errno($link);
}

fixed the issue. Will look into that further I get a generic error message, and have no idea what the problem is with the query. What do I do to fix this? , Add semicolon after each command.
code :
START TRANSACTION;

UPDATE 
Invoice
SET 
Invoice.zip_code = (SELECT zip_code FROM temp WHERE temp.invoice_number = Invoice.invoice_number)
WHERE 
Invoice.invoice_date >= '2017-08-01';
