Is it possible to execute SQL procedure in Delphi 6 BDE TUpdateSQL? -


is possible write execute procedure (...with arguments...) (for firebird 2.1 database) in delphi 6 bde tupdatesql.modifysql? have tried, receiving error message update failed simplest sql procedure. - there restrictions on statement can executed in modifysql? know (and using extensively), possible write execute procedure (and more complex statements) in delphi ibx tibdataset.modifysql (or in other similar properties of ibx components). should avoid execute procedure in tupdatesql or there tricks should take consideration?

rené hoffmann's idea right - possible execute procedure update statement. e.g. following statement accepted in modifysql:

update target_table set   id = :id,   field1 = :field1,   field2 = (select proc.field2 additional_actions_procedure(:field2, :param1, :param2) proc)     id = :old_id

delphi unit dbtables contains code explains why exception raised:

procedure tupdatesql.execsql(updatekind: tupdatekind); begin   query[updatekind]   begin     prepare;     execsql;     if rowsaffected <> 1 databaseerror(supdatefailed);   end; end;

so affected rows counting happens. apparently dbtables accounting of affected rows differs affected rows count in ibexpert. ibexpert counts real affected rows affected execute procedure, update statement or other statements. dbtables counts (my guess) rows of target table updated update statement. more investigation of delphi code can reveal more exact explanation.

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() .
