  Notes
  
   By default, warnings generated on a call to any SQLSRV function are treated 
   as errors. This means that if a warning occurs on a call to a SQLSRV function, 
   the function returns FALSE. However, warnings that correspond to SQLSTATE 
   values 01000, 01001, 01003, and 01S02 are never treated as errors. For 
   information about changing this behavior, see sqlsrv_configure 
   and the WarningsReturnAsErrors setting.
