mysql - Trouble with a simple inner join for multiple tables -

-

edit: made little change. added table db_supplier (supplier_id, supply_speed_id) , changed lookup_supply_speed (supplier_id, supplier_speed) lookup_supply_speed (supplier_speed_id, supplier_speed)

my tables:

db_supply  ----------------------------------------------- | supplier_id | supply_type_id | itm_id | stock | |-----------------------------------------------| | 1           | 1              | 33     | 3     | |-----------------------------------------------| | 2           | 2              | 28     | 1     |  -----------------------------------------------  db_supplier  ---------------------------------------- | supplier_id | supply_speed_id | etc... | |----------------------------------------| | 1           | 1               |        | |----------------------------------------| | 2           | 2               |        |  ----------------------------------------  lookup_supplier_name  ----------------------------- | supplier_id | supplier_name | |-----------------------------| | 1           | walter        | |-----------------------------| | 2           | jesse         |  -----------------------------  lookup_supply_type  ----------------------------------- | supply_type_id | supply_type_name | |-----------------------------------| | 1              | import           | |-----------------------------------| | 2              | delivery         |  -----------------------------------  lookup_itm  ------------------------ | itm_id | itm_name      | |------------------------| | 33     | pickles       | |------------------------| | 28     | burger        |  ------------------------  lookup_supply_speed  ------------------------------------ | supplier_speed_id | supplier_speed | |------------------------------------| | 1                 | fast           | |------------------------------------| | 2                 | slow           |  ------------------------------------  query 'burger' output table:  ---------------------------------------------------------------------- | supplier_name | supply_type_name | itm_name | stock | supplier_speed | |----------------------------------------------------------------------| | jesse         | delivery         | burger   | 1     | slow           |  ----------------------------------------------------------------------

problem: can't produce sql statement me supplier_speed column since lookup_supply_speed not have fk association db_supply (all other tables do).

sql below give me this: (we query itm_name e.g. burger)

 ----------------------------------------------------- | supplier_name | supply_type_name | itm_name | stock | |-----------------------------------------------------| | jesse         | delivery         | burger   | 1     |  ----------------------------------------------------- select  b.supplier_name,         c.supply_type_name,         d.itm_name,         a.stock    db_supply         inner join lookup_supplier_name b             on a.supplier_id = b.supplier_id         inner join lookup_supply_type c             on a.supply_type_id = c.supply_type_id         inner join lookup_itm d             on a.itm_id = d.itm_id   d.itm_name = 'burger'

how can modify can join lookup_supplier lookup_supply_speed via db_supplier , join rest?

sqlfiddle: http://www.sqlfiddle.com/#!2/9635d/3

how this?

select  f.supplier_name,         b.supplier_id,         c.supply_type_name,         d.itm_name,         a.stock,         e.supplier_speed    db_supply         inner join db_supplier b             on a.supplier_id = b.supplier_id         inner join lookup_supplier_name f             on f.supplier_id = b.supplier_id         inner join lookup_supply_type c             on a.supply_type_id = c.supply_type_id         inner join lookup_itm d             on a.itm_id = d.itm_id         inner join lookup_supply_speed e             on e.supplier_speed_id = b.supply_speed_id   d.itm_name = 'burger'

android - getbluetoothservice() called with no bluetoothmanagercallback -

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
