SQL server Update incomplete

I am trying to create a table with editable fields and at the end of the table that has an update button, this is my sentence when I pass the update (the table and the update I try to keep it as simple as possible afterwards. It's hard to see what I did : o):

$query = "UPDATE usuarios SET 
                 incdia    ='$incdia1', 
                 pago             ='$pago1', 
                 sueldos          ='$sueldos1',
                 Pasajes             ='$pasajes1',  
                 dias_trabajados  ='$dias_trabajados1', 
                 dias_adicionales ='$dias_adicionales1'  
          WHERE Id_usuario = '$id' ";

I'm working on SQL server and something has happened VERY rraro when running my Querry I do not get error update the first 833 items but after there is nothing saved or update anything

I find it strange because it stops working in the middle of the table and the previous thing does perfectly

I have more experience in phpmyadmin and is the first time I face SQL server for a page, will it have any restrictions or something where I can correct?
