sql - Query taking too much -

-

i trying execute updates while condition returns results, problem when testing query never finishes. here query;

while(select count(*) agreement agr agr.id in (   select toa.id agreement_temporaryonceagreement toa toa.executed =1) , agr.endingdate null) > 0 begin declare @agreementid int; set @agreementid =  ( select top 1 agr.id agreement agr agr.id in (   select toa.id agreement_temporaryonceagreement toa toa.executed =1) , agr.endingdate null ) update agreement set endingdate = (   select tado.date temporaryagreementsdateofexecution tado     tado.agreementid = cast(@agreementid int)) agreement.id = cast(@agreementid int); end;

you don't need loop. single update query resembling should job done.

update set endingdate = tado.date agreement join temporaryagreementsdateofexecution tado on a.agreementid = tado.agreementid  join agreement_temporaryonceagreement toa on a.id = toa.id  endingdate null , toa.executed = 1

there might slight variations depending on rdbms using.

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
