php - Unknown column 'Process_Status' in 'where clause' -

$result = mysql_query('select * accounting  acctstatustype = "start" , process_status null limit 10'); if($result === false)  {     die(mysql_error()); } 

the following code spits back

unknown column 'process_status' in 'where clause'

however, when copy , paste query

select * accounting acctstatustype = "start" , process_status null limit 10

directly mysql, successful.

i bit new php/mysql queries have worded differently when parsing them php?

thanks,

matt
