  • Delphi plugin for pasting text constants in source code?

    - by mjn
    Inserting (pasting from clipboard) of text constants in the Delphi code editor requires some manual "postprocessing" ... split up long text into multiple lines (and insert the string concatenation symbol) escape quotes (replace single quotes with double quotes) enclose the string with quotes keep original white space (leadinng blanks, line feeds) Is there a IDE plugin available which helps to reduce these manual steps?

  • Why (and when to) use stored procedures?

    - by mr.b
    What would be appropriate scenario when stored procedures should be used? I stumbled upon implementation where almost whole data manipulation was handled by store procedures, even simplest form of INSERT/DELETE statements were wrapped and used via SP's. So, what's the rationale for using stored procedures in general? Sorry for such a beginners question..

  • VB.Net HTTPWebRequest Speed is slow comparing Python URLOpen

    - by regexhacks
    Hi I am coding a web-crawler which will crawl the websites and selectively parse different sections of a web site. I am a .Net developer so the choice was obvious that I did it in .Net but the speed was very slow which included downloading and parsing of HTMLPages Then I tried to just download the contents first using .Net and then same domains using python but the python was very impressive in downloading data. I have achieved downloading using python but the later part is not that easy to code in python, which obviously i don't want to do. The same batch of domain which took 100 seconds in Python was taking 20 minutes in .Net based crawler I tried http://www.eqlit.com/ to download and in took 8 seconds in Python and same was taking 100 Seconds in .Net crawler Does anyone anyone have any idea why this is slow in .Net but fast in python?

  • hibernate annotation- extending base class - values are not being set - strange error

    - by gt_ebuddy
    I was following Hibernate: Use a Base Class to Map Common Fields and openjpa inheritance tutorial to put common columns like ID, lastModifiedDate etc in base table. My annotated mappings are as follow : BaseTable : @MappedSuperclass public abstract class BaseTable { @Id @GeneratedValue @Column(name = "id") private int id; @Column(name = "lastmodifieddate") private Date lastModifiedDate; ... Person table - @Entity @Table(name = "Person ") public class Person extends BaseTable implements Serializable{ ... Create statement generated : create table Person (id integer not null auto_increment, lastmodifieddate datetime, name varchar(255), primary key (id)) ; After I save a Person object to db, Person p = new Person(); p.setName("Test"); p.setLastModifiedDate(new Date()); .. getSession().save(p); I am setting the date field but, it is saving the record with generated ID and LastModifiedDate = null, and Name="Test". Insert Statement : insert into Person (lastmodifieddate, name) values (?, ?) binding parameter [1] as [TIMESTAMP] - <null> binding parameter [2] as [VARCHAR] - Test Read by ID query : When I do hibernate query (get By ID) as below, It reads person by given ID. Criteria c = getSession().createCriteria(Person.class); c.add(Restrictions.eq("id", id)); Person person= c.list().get(0); //person has generated ID, LastModifiedDate is null select query select person0_.id as id8_, person0_.lastmodifieddate as lastmodi8_, person0_.name as person8_ from Person person0_ - Found [1] as column [id8_] - Found [null] as column [lastmodi8_] - Found [Test] as column [person8_] ReadAll query : //read all Query query = getSession().createQuery("from " + Person.class.getName()); List allPersons=query.list(); Corresponding SQL for read all select query select person0_.id as id8_, person0_.lastmodifieddate as lastmodi8_, person0_.name as person8_ from Person person0_ - Found [1] as column [id8_] - Found [null] as column [lastmodi8_] - Found [Test] as column [person8_] - Found [2] as column [id8_] - Found [null] as column [lastmodi8_] - Found [Test2] as column [person8_] But when I print out the list in console, its being more weird. it is selecting List of Person object with ID fields = all 0 (why all 0 ?) LastModifiedDate = null Name fields have valid values I don't know whats wrong here. Could you please look at it? FYI, My Hibernate-core version : 4.1.2, MySQL Connector version : 5.1.9 . In summary, There are two issues here Why I am getting All ID Fields =0 when using read all? Why the LastModifiedDate is not being inserted?

  • deleting a large number of rows from a table

    - by Azeem
    We have a requirement to delete rows in the order of millions from multiple tables as a batch job (note that we are not deleting all the rows, we are deleting based on a timestamp stored in an indexed column). Obviously a normal DELETE takes forever (because of logging, referential constraint checking etc.). I know in the LUW world, we have ALTER TABLE NOT LOGGED INITIALLY but I can't seem to find the an equivalent SQL statement for DB2 v8 z/OS. Any one has any ideas on how to do this really fast? Also, any ideas on how to avoid the referential checks when deleting the rows? Please let me know.

  • Trouble editing Word document with PHP

    - by bhoomi-nature
    I want to open a word document and edit it I am opening the word document from the server and at that time it's opening with garbage values (perhaps it's not being properly converted to UTF-8). When I delete those garbage values and insert something from a textarea to that file it is going to insert and from then on it opens properly. I would like the document to open with the English words in the document instead of garbage value - it's only the first opening that's broken at present. <? $filename = 'test.doc'; if(isset($_REQUEST['Submit'])){ $somecontent = stripslashes($_POST['somecontent']); // Let's make sure the file exists and is writable first. if (is_writable($filename)) { // In our example we're opening $filename in append mode. // The file pointer is at the bottom of the file hence // that's where $somecontent will go when we fwrite() it. if (!$handle = fopen($filename, 'w')) { echo "Cannot open file ($filename)"; exit; } // Write $somecontent to our opened fi<form action="" method="get"></form>le. if (fwrite($handle, $somecontent) === FALSE) { echo "Cannot write to file ($filename)"; exit; } echo "Success, wrote ($somecontent) to file ($filename) <a href=".$_SERVER['PHP_SELF']."> - Continue - "; fclose($handle); } else { echo "The file $filename is not writable"; } } else { // get contents of a file into a string $handle = fopen($filename, 'r'); $somecontent = fread($handle, filesize($filename)); ?> <h1>Edit file <? echo $filename ;?></h1> <form name="form1" method="post" action=""> <p> <textarea name="somecontent" cols="80" rows="10"><? echo $somecontent ;?></textarea> </p> <p> <input type="submit" name="Submit" value="Submit"> </p> </form> <? fclose($handle); } ?>
