sql - MYSQL statement together OR and AND -

-

i have table in mysql named sale 3 columns below : sale:

id|customers|type

i want select sales has type!=2 or sales has type=2 , customers!=0

i write statement :

sale.type != 2 or (sale.type = 2 , sale.customers != 0 )

but doesn`t give me correct rows .

also have use , other columns in query operators between of them , , here use or .

just remember rule: bracket or!

where foo = 'bar' , (sale.type != 2 or (sale.type = 2 , sale.customers != 0 ) ) , blah = 3

actually condition can simplified to:

( sale.type != 2 or sale.customers != 0 )

because logically checking sale.type = 2 redundant.

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
