  • std::map insert segmentation fault

    - by Jakub Czaplicki
    Why does this code stop with segmentation fault : class MapFile { public: /* ... */ std::map <unsigned int, unsigned int> inToOut; }; bool MapFile::LoadMapFile( const wxString& fileName ) { /* ... */ inToOut.insert( std::make_pair(input,output) ); } but this one works fine : class MapFile { public: /* ... */ }; bool MapFile::LoadMapFile( const wxString& fileName ) { /* ... */ std::map <unsigned int, unsigned int> inToOut; inToOut.insert( std::make_pair(input,output) ); } ?

  • Check if row already exists, if so tell the referenced table the id

    - by flhe
    Let's assume I have a table magazine: CREATE TABLE magazine ( magazine_id integer NOT NULL DEFAULT nextval(('public.magazine_magazine_id_seq'::text)::regclass), longname character varying(1000), shortname character varying(200), issn character varying(9), CONSTRAINT pk_magazine PRIMARY KEY (magazine_id) ); And another table issue: CREATE TABLE issue ( issue_id integer NOT NULL DEFAULT nextval(('public.issue_issue_id_seq'::text)::regclass), number integer, year integer, volume integer, fk_magazine_id integer, CONSTRAINT pk_issue PRIMARY KEY (issue_id), CONSTRAINT fk_magazine_id FOREIGN KEY (fk_magazine_id) REFERENCES magazine (magazine_id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION ); Current INSERTS: INSERT INTO magazine (longname,shotname,issn) VALUES ('a long name','ee','1111-2222'); INSERT INTO issue (fk_magazine_id,number,year,volume) VALUES (currval('magazine_magazine_id_seq'),'8','1982','6'); Now a row should only be inserted into 'magazine', if it does not already exist. However if it exists, the table 'issue' needs to get the 'magazine_id' of the row that already exists in order to establish the reference. How can i do this? Thx in advance!

  • Selecting an item in an HTML SELECT list using keyboard doesnt trigger the CLICK event

    - by Jimbo
    I have an HTML select list which, when an item is selected, must show different information beneath it. The onclick or JQuery change events are triggered when a select list item is selected by being clicked on (mouse), but not when the user uses key presses (keyboard). Any idea what event to watch in order to determine when the selected list item has changed? Here is a BASIC test example: <select id="mylist" name="mylist"> <option value="">(none)</option> <option value="1">Test 1</option> <option value="2">Test 2</option> <option value="3">Test 3</option> </select> <span id="myspan"></span> <script type="text/javascript"> $("#mylist").change(function() { $("#myspan").html($("#mylist").attr("selectedIndex")); }); </script>

  • PHP - error when insert date into MySQL

    - by Michael Mao
    Hello everyone: I've got a typical problem when trying to insert a date into MySQL. The column defined in MySQL is of type DATE. My PHP version is 5.3.0 Apart from this date-related issue, the rest of my code works just fine. And this is my PHP script to do this: $tablename = BOOKS_TABLE; $insert = mysql_query("INSERT INTO $tablename (barcode, book_name, volume_num,". " author, publisher, item_type, buy_price, buy_date) VALUES ". "(". "'" . $barcode . "', ". "'" . $bookname . "', ". "'" . $volumenum . "', ". "'" . $author . "', ". "'" . $publisher . "', ". "'" . $itemtype . "', ". "'" . $buyprice . "', ". "'" . getMySQLDateString($buydate). //"'STR_TO_DATE('".$buydate ."', '%d/%m/%Y'))'". //nothing changes in MySQL ")"); And this is the faulty function : function getMySQLDateString($buydate) //typical buydate : 04/21/2009 { $mysqlDateString = date('Y-m-d H:i:s', $strtotime($buydate)); return $mysqlDateString; } The first commented out line wouldn't do anything, the script is executed with no error, however, there is nothing changed in datebase after this. The current approach will cause a Fatal error saying function name must be a string in this line. Actually I followed this thread on SO, but just cannot pass the date into MySQL... Can anyone help me figure out which part is not right? How would you do it, in this case, to get it right? Sorry about such a journeyman-like question, thanks a lot in advance.

  • JsonStore.insert() causes exception in extjs

    - by kalan
    I have an EditorGridPanel with toolbar button to add new records. Everything works fine except one scenario. When I try to insert a record which already exists in database, server sends back: {"success":false,"message":"already exists","data":{}} but grid creates a new row marked with red triangle. If after that I try to insert a new record (even if it doesn't exist in database), everything works fine on the server side, but i get an 'uncaught exception' in firebug. It says: 'uncaught exception: Ext.data.DataReader: #realize was called with invalid remote-data. Please see the docs for DataReader#realize and review your DataReader configuration.' why is that?

  • rails large amount of data in single insert activerecord gave out

    - by Nik

So I do: so I collected them into one single insert statement sql = "INSERT INTO tasks (attrib_a, attrib_b) VALUES (c1,d1),(c2,d2),(c3,d3)...(c36000,d36000);" ActiveRecord::Base.connection.execute sql from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/abstract_adapter.rb:219:in `log' from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute_without_analyzer from c:/r/projects/vendor/plugins/rails-footnotes/lib/rails-footnotes/notes/queries_note.rb:130:in `execute' from C:/Ruby/lib/ruby/1.8/benchmark.rb:308:in `realtime' from c:/r/projects/vendor/plugins/rails-footnotes/lib/rails-footnotes/notes/queries_note.rb:130:in `execute' from (irb):53 from C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/vendor/tzinfo-0.3.12/tzinfo/time_or_datetime.rb:242 I don't know if the above info is enough, please do ask for anything that I didn't provide here. So any idea what this is about? THANK YOU!!!!

The data above represents separate rows of the "Node" column. Is there an easy way to insert this data, all in one command? Also, the data will actually being coming in as seen, as a string... so I need to be able to just concat it into the SQL query string. I can obviously modify it first if needed.

  • Select calls seems to not time out.

    - by martsbradley
    HI Folks, I have a threaded C++ program where up to three threads are calling select on a three separate socket descriptors waiting for data to become available. Each thread handles one socket and adds it to the readfds with a timeout of 300 seconds. After select returns if there is data available I'm calling recv to read it. Is there anything that I need to be aware of with winsock and threads because for some reason after a number of hours the select calls all seem to be not timing out. Can a multi threaded program select from a number of threads without issue? I know that I should have one thread listening to all three sockets however that would be a large change for this app and I'm only looking to apply a bug fix. cheers, Martin.

  • How to perform a select using a WHERE NOT EXISTS

    - by Peter Bridger
    I'm using LINQ2SQL and I want to compare two tables and select all rows that are missing from one tables (based upon one of the column values). In standard SQL I would write this as: SELECT FirstName, LastName, RefId, Email FROM Users_ActiveDirectory AS ADU WHERE NOT EXISTS ( SELECT U.RefId FROM Users AS U WHERE U.RefID = ADU.RefId ) However I'm not sure how to achieve the same result using LINQ2SQL?

  • Disable Primary Key and Re-Enable After SQL Bulk Insert

    - by Jon
    I am about to run a massive data insert into my DB. I have managed to work out how to enable and rebuild non-clustered indexes on my tables but I also want to disable/enable primary keys. You can't disable the clustered index for the primary key as the table is inaccessible when that is done and my attempt to do a ALTER TABLE for constraints does not work as I think that is only for foreign keys. Do you know of a way to Disable the Primary Key and Re-Enable After SQL Bulk Insert. NOTE: This is over numerous tables and so I don't know the exact primary key specifications eg/name etc
