datastep - Is there a way to force cleansing the raw data before importing it via a data step, in SAS? -


sas eg

i have tab delimited text file has imported every month. wrote import procedure via data step.

data lib.txtimp; %let _efierr_=0; infile "file/path/tabdlm.txt" lrecl=256 dlm='09'x missover firstobs=2 dsd; informat <vars>; format <vars>; input <vars>; if _error_ call symput('_efierr_',1); run;

a recent problem had there times when datalines have 2 tabs mistake. text file huge, in order of 500mb. tried automate process writing above, doesn't take problem in consideration. writes blank in place. when use in-built 'import data', first cleanses raw file , runs intermediate data step give desired output. doesn't give me blank in column. ignores tab.

an example of problem text file.

col1   col2   col3 1     b 2   foo   bar 3      wayout   data 4        example

sample file

is there way can automate cleansing process data step import? or, guys know steps should add of sort?

remove dsd option. dsd option tells sas treat 2 consecutive delimiters missing, whereas standard approach treat 2 consecutive delimiters single delimiter.

i cannot replicate issue. code works fine me on sas 9.4 ts1m3.

data txtimp; infile "c:\_localdata\temp\sample_tab_dlm_file.txt"  missover lrecl=256 dlm='09'x  firstobs=2 ; input col1 $ col2 $ col3 $; run;

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() .
