BEFORE_OURCE_OBAT = '1' AND ROOM = 'ORCHID' AND MONTH (DATE) = '$ month' ";

If that is all your code then the $conn = sqlsrv_connect() is missing.

My guess is that the MySQLi connect function exists somewhere in the framework, etc., and not necessarily right above where a query call is being made.

Obviously here sqlsrv_query() is returning FALSE. This can happen because the SQL query is invalid. It can be invalid for a number of reasons:

  • NAME_TABEL doesn't exist or it's a typo and it's supposed to be NAME_TABLE
  • Table doesn't have columns BEFORE_OURCED_OBAT and ROOM
  • $ month is invalid ... it should be $month without a space, and you need to be properly escaping this variable to prevent SQL injections!
