sql server 2008 - MDX MAX MEMBER_KEY return wrong result -


i trying determine max dimension key processed cube can write view return new data process add operation.

i came across couple of links showing same thing. changed these examples bit , determined max date key within date dimension.

with member [measures].[maxkey]     max([dim date].[date sk].allmembers     ,strtovalue([dim date].[date sk].currentmember.member_key)) select     {[measures].[maxkey]} on 0     [pgl dw]

as expected results of above query 20170730

when change query execute against agent dimension returns incorrect value.

with member [measures].[maxkey]    max([dim agent].[dim agent key].members    , [dim agent].[dim agent key].currentmember.member_key) select    {[measures].[maxkey]} on 0    [pgl dw]

the value return above query "-6" incorrect.

if list dim agent member keys using below query values of 100000+

with member [measures].[dim agent key] [dim agent].[dim agent key].currentmember.member_key select {measures.[dim agent key]} on axis(0), [dim agent].[dim agent key].members on axis(1) [pgl dw]

query results

the dim agent key attribute dimension's key attribute it's keycolumn set dim agent.dim_agentkey (integer).

any idea why query returning incorrect results when querying agent dimension?

if find maximum of membervalue rather key still -6?

with member [measures].[maxkey]    max([dim agent].[dim agent key].[dim agent key].members    , [dim agent].[dim agent key].currentmember.membervalue) select    {[measures].[maxkey]} on 0    [pgl dw];

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
