sql server - pandas + pyodbc ODBC SQL type -150 is not yet supported -


i know there many topics on think specific. current code audit purpose:

import pandas pd import pyodbc  query = """ --top 50 high total cpu queries select top 50 'high cpu queries' type, serverproperty('machinename') 'server name', isnull(serverproperty('instancename'),serverproperty('machinename')) 'instance name',         coalesce(db_name(qt.dbid),         db_name(cast(pa.value int)),          'resource') dbname,     qs.execution_count [execution count],     qs.total_worker_time/1000 [total cpu time],     (qs.total_worker_time/1000)/qs.execution_count [avg cpu time],     qs.total_elapsed_time/1000 [total duration],     (qs.total_elapsed_time/1000)/qs.execution_count [avg duration],     qs.total_physical_reads [total physical reads],     qs.total_physical_reads/qs.execution_count [avg physical reads],     qs.total_logical_reads [total logical reads],     qs.total_logical_reads/qs.execution_count [avg logical reads], substring(qt.text,qs.statement_start_offset/2,          (case when qs.statement_end_offset = -1          len(convert(nvarchar(max), qt.text)) * 2          else qs.statement_end_offset end -qs.statement_start_offset)/2)         query_text          sys.dm_exec_query_stats qs     cross apply sys.dm_exec_sql_text(qs.sql_handle) qt     outer apply sys.dm_exec_query_plan (qs.plan_handle) qp     outer apply sys.dm_exec_plan_attributes(qs.plan_handle) pa     attribute = 'dbid'        order          [total cpu time] desc """ cnxn = pyodbc.connect('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx') cnxn.execute(query).fetchall() cnxn.close()

i following error:

cnxn.execute(sql_status_20).fetchall() traceback (most recent call last): file "", line 1, in pyodbc.programmingerror: ('odbc sql type -150 not yet supported. column-index=1 type=-150', 'hy106')

anyone can me handle ? have same problem many sql server audit scripts using dates , can't change driver have kind of sql versions in production env.

if can't change driver, you'll need change query return data types supports.

sql type -150 sql_variant, returned serverproperty. workaround explicitly cast column supported type nvarchar:

cast(serverproperty('machinename') nvarchar(100)) 'server name', cast(isnull(serverproperty('instancename'),serverproperty('machinename')) nvarchar(100)) 'instance name',

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() .
