  • In Blackberry's Application class what is the difference between hasEventThread() and isHandlingEven

    - by Eric Sniff
    In Blackberry's Application class what is the difference between hasEventThread() and isHandlingEvents(). I'm just curious, because I have only found hasEventThread useful. From BB's docs for Applicaiton: public boolean hasEventThread() Determines if this application has entered the event dispatcher. Returns: True if this application has entered the event dispatcher (i.e. has invoked Application.enterEventDispatcher()); otherwise, false. isHandlingEvents public final boolean isHandlingEvents() Determines if this application has entered the event dispatch loop. Returns: True if the application has entered the event dispatch loop; otherwise, false. My only guess is that isHandlingEvents most happen sometime after hasEventThread. But is that really that useful?

  • Why is IE not adhering to my column widths?

    - by Trent
    This has been driving my crazy trying to solve Code: http://pastebin.com/rqyw35jG First of all, I'm rendering in standards mode. I have a table in IE, with width=100%, and all columns in the table with specified widths except the last column. The intended behaviour is for IE to size the final column so it stretches to the page. This more or less works. However; Certain conditions seem to break the table widths and cause IE to go and size the table however it pleases. The table contains a row which is merged across all columns AND This merged row contains enough text to fill the whole cell AND Enough text is entered into one of the cells whose column had unspecified width, causing the text to wrap. When this 3 conditions occur, all the columns move slightly. The text still wraps and you wouldn't normally notice that the columns are the wrong size unless you measure them, or compare the page to a version without wrapped text. Is this even supposed to happen in standards mode? Code: <%@ Page Language="VB" %> <%@ Import Namespace="Microsoft.SharePoint.Client" %> <%@ Import namespace="System.Data" %> <%@ Import Namespace="System.Data.SQLClient" %> <script runat="server"> Protected Sub Page_Load(sender As Object, e As System.EventArgs) End Sub </script> <% %> <!DOCTYPE html /> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <table style="width:100%;"> <tr> <td style="width:500px;">egqwgw gqgqwgqg qwgqgqg qgwgqgqg qwgqgg</td> <td style="width:500px;">gqgqwgqg gqwgqgqgq gqgqgqg qgg</td> <td>If too much text is entered into this column, the column sizes will begin to change. wehwehweh hwehwh whhwhwh hwehwhwh</td> </tr> <tr> <td>a gqwgqwg gqgqw </td><td>gqgqgqg gqgqg</td><td></td> </tr> <tr> <td colspan="3">Columns only move if text on this line is filling out the whole width of the page. gqwgqwggqg qgqgqwgqg qgqwgqgqg gqgwqgqg gqgqgqgqg qgqgqgqg gqgggqg qgwgqgqg gqgqgqwgwg qgqwgqgqgq gqgwgwgqg gqgwgq gqwgwgqgqwg qgwgqgqgqwg qwgqwgqgqg qgwgqgqqg gqwgqwgqwgwqg gqgwgqgwg qwgqwgqgqgq qwgqgqgqg gwqgqgqg qggqwgqg qggwqgqg </td> </tr> </table> </body> </html>

  • Multiple ID's in database

    - by eric
    I have a database that contains a few tables such as person, staff, member, and supporter. The person table contains information about every staff, member, and supporter. The information it contains is name,address,email, and telephone. I also created an id that is the primary key. My issue is that I also have an primary key ID for staff, member, and supporter. For instance, in the person table is John with id 1. He is a supporter so in the supporter table is pID(for person id)to reference back to John with all his information and ID(for supporter ID). pID references to the person table and every person has an ID incremented by 1 starting at 1. supporter ID is for every supporter and also starts at 1 and is incremented by 1. Is it possible to have in the supporter table pID = 1 and supporter ID = 1? Another person may have a pID = 26 and supporter ID = 5. Or will supporter ID have to be different than the pID and be something like "sup"? So you would have pID = 1 and supporter ID = sup1 or pID = 26 and supporter ID = sup5

  • What's the best way to store custom objects in relational database?

    - by user342610
    I have my objects with their properties. Objects could change their structure: properties may be added/removed/changed. Objects could be absolutely dropped. So object's metadata (description, classes, call them like you want :) )could be changed. The database should store objects schemas and instances of these objects. What's the best way to organise a relational database structure to store data mentioned above? Currently I see only two ways: 1) Store objects schemas in a few tables: schema general data,schema properties, possible properties types. Store instances in their tables: instance general data, a few tables - per each type from possible properties types table to store instance properties data. And so on. 2) store objects schemas like in p1 but store instances like XML files in one table: one table for general instance info and one table with instance XML. please, don't ask why/for what I need this. Just need to store custom objects and DB should work fast :)

  • How can I treat a sequence value like a generated key?

    - by Jeff Knecht
    Here is my situation and my constraints: I am using Java 5, JDBC, and DB2 9.5 My database table contains a BIGINT value which represents the primary key. For various reasons that are too complicated to go into here, the way I insert records into the table is by executing an insert against a VIEW; an INSTEAD OF trigger retrieves the NEXT_VAL from a SEQUENCE and performs the INSERT into the target table. I can change the triggers, but I cannot change the underlying table or the general approach of inserting through the view. I want to retrieve the sequence value from JDBC as if it were a generated key. Question: How can I get access to the value pulled from the SEQUENCE. Is there some message I can fire within DB2 to float this sequence value back to the JDBC driver?

  • Counting character count in Access database column ins SQL

    - by jzr
    Good Evening. My problem is possibly very easy, I just have spent some time researching now and probably have a brain lock and unable to solve this, help would be much appreciated. database structure: col1 col2 col3 col4 ==================== 1233+4566+ABCD+CDEF 1233+4566+ACD1+CDEF 1233+4566+D1AF+CDEF I need to count character count in col3, wanted result in from the previous table would be: char count =========== A 3 B 1 C 2 D 3 F 1 1 2 is this possible to achieve by using SQL only? at the moment I am thinking of passing a parameter in to SQL query and count the characters one by one and then sum, however I did not start the VBA part yet, and frankly wouldn't want to do that. this is my query at the moment: PARAMETERS X Long; SELECT First(Mid(TABLE.col3,X,1)) AS [col3 Field], Count(Mid(TABLE.col3,X,1)) AS Dcount FROM TEST GROUP BY Mid(TABLE.col3,X,1) HAVING (((Count(Mid([TABLE].[col3],[X],1)))>=1)); ideas and help are much appreciated, as being said this is probably very for some of your guys, I don't usually work with access and SQL. Thanks.

  • SQL Server column level security

    - by user46372
    I think I need some pointers on security in SQL Server. I'm trying to restrict some of our end users from getting access to certain columns (i.e. SSN) on a table. I thought I could just use column level security to restrict access to the columns. That successfully prevented users from accessing the table directly, but I was surprised that they could still get to those columns through a view that accessed that table. I followed the tips here: http://www.mssqltips.com/sqlservertip/2124/filtering-sql-server-columns-using-column-level-permissions/ Those were very helpful, but when I created a view at the end, the intern was able to access that column by default I've read that views are the best way to accomplish this, but I really don't want to go through and change all of the views and the legacy front-end application. I would rather just restrict it once on the table and if a view tries to access that column it would just fail. Is that possible or am I misunderstanding how security works in SQL Server?

  • SQL update statement to change the value of a field and not replace it

    - by wzzrd
    I'm in the process of migrating some databases. I have this table that has a couple of hundred rows, and has a filename column. To each record in this table, the filename column needs to be altered and part of a path needs to be prepended to the value that is in that field. The table is like: | 1 | filename1 | | 2 | filename2 | and needs to become: | 1 | path/filename1 | | 2 | path/filename2 | I am not an SQL guru, but I know the basics. This eludes me though. Is there a way to do something like: update table set filename = 'path/' + filename where id = 1;

  • Mysql dropping inserts with triggers

    - by user2891127
    Using mysql 5.5. I have two tables. One has a whitelist of hashes. When I insert a new row into the other table, I want to first compare the hash in the insert statement to the whitelist. If it's in the whitelist, I don't want to do the insert (less data to plow through later). The inserts are generated from another program and are text files with sql statements. I've been playing with triggers, and almost have it working: BEGIN IF (select count(md5hash) from whitelist where md5hash=new.md5hash) 0 THEN SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = 'Already Whitelisted'; END IF; END But there's a problem. The Signal throwing up the error stops the import. I want to skip that line, not stop the whole import. Some searching didn't find any way to silently skip the import. My next idea was to create a duplicate table definition, and redirect the insert to that dup table. But the old and new don't seem to apply to table names. Other then adding an ignore column to my table then doing a mass drop based on that column after the import, is there any way to achieve my goal?

  • Should multiple regional websites all use the same database?

    - by John Himmelman
    I'm developing a cms for a company that has multiple regional sites (us, uk, china, russia, etc..). Should I use a separate database for each of these sites or use a single database with a 'site' field in each table? My main concern is the table language encoding (ie, can storing strings in different langauges in the same table cause problems, such as sorting issues).

  • MYSQL variables - SET @var

    - by Lizard
    I am attempting to create a mysql snippet that will analyse a table and remove duplicate entries (duplicates are based on two fields not entire record) I have the following code that works when I hard code the variables in the queries, but when I take them out and put them as variables I get mysql errors, below is the script SET @tblname = 'mytable'; SET @fieldname = 'myfield'; SET @concat1 = 'checkfield1'; SET @concat2 = 'checkfield2'; ALTER TABLE @tblname ADD `tmpcheck` VARCHAR( 255 ) NOT NULL; UPDATE @tblname SET `tmpcheck` = CONCAT(@concat1,'-',@concat2); CREATE TEMPORARY TABLE `tmp_table` ( `tmpfield` VARCHAR( 100 ) NOT NULL ) ENGINE = MYISAM ; INSERT INTO `tmp_table` (`tmpfield`) SELECT @fieldname FROM @tblname GROUP BY `tmpcheck` HAVING ( COUNT(`tmpcheck`) > 1 ); DELETE FROM @tblname WHERE @fieldname IN (SELECT `tmpfield` FROM `tmp_table`); ALTER TABLE @tblname DROP `tmpcheck`; I am getting the following error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '@tblname ADD `tmpcheck` VARCHAR( 255 ) NOT NULL' at line 1 Is this because I can't use a variable for a table name? What else could be wrong or how wopuld I get around this issue. Thanks in adavnce

  • How to design a database schema for storing text in multiple languages?

    - by stach
    We have a PostgreSQL database. And we have several tables which need to keep certain data in several languages (the list of possible languages is thankfully system-wide defined). For example lets start with: create table blah (id serial, foo text, bar text); Now, let's make it multilingual. How about: create table blah (id serial, foo_en text, foo_de text, foo_jp text, bar_en text, bar_de text, bar_jp text); That would be good for full-text search in Postgres. Just add a tsvector column for each language. But is it optimal? Maybe we should use another table to keep the translations? Like: create table texts (id serial, colspec text, obj_id int, language text, data text); Maybe, just maybe, we should use something else - something out of the SQL world? Any help is appreciated.

  • When using SELECT can you modify the value of a returned field based on other fields?

    - by user570759
    When using MySQL SELECT can you change the value of a returned field based on other fields? For example, if I have this select: SELECT city,state,country FROM table Now if city is empty AND state is empty, I want the value of country to returned empty as well (whether country actually has a value or not). Example table: id | city | state | country ----------------------------- 1 | Here | There | MyCountry 2 | | | YourCountry So with the above table, I want the results for id=1 to return Here,There,MyCountry but the results for id=2 should be empty,empty,empty Thanks

  • Can't seem to get my like/dislike to work in PHP

    - by user300371
    My table is comment_likedislike. It has the comment_counterid, comment_counter, comment_id(which is from another table) fields. And I have an url (LIKE) that when clicked would link to this code and get the comment_id and like_id. I want to do a count where if it is the first 'like', it would store a new comment_counter in the comment_likedislike table. But if there is already a 'like' for the comment in the table, it would just update the comment_counter to +1. Problem: When I run this code, it doesn't UPDATE(1st statement) but INSERT(2nd if statement) no matter if there is a like for the comment or not. I don't think the code is checking if the comment_id is in the table already. I am a novice php programmer. Thanks! if (isset($_GET['comment_id']) && isset($_GET['like_id'])) { $query5="SELECT * FROM comment_likedislike "; $data5=mysqli_query ($dbc, $query5); while ($row5= mysqli_fetch_array($data5)){ $comment_id2=$row5['comment_id']; } if ($comment_id2 == $_GET['comment_id']){ $counter=$row5['comment_counter']; $counter++; $query= "UPDATE comment_likedislike SET comment_counter ='$counter' WHERE comment_id= '".$_GET['comment_id']."' "; mysqli_query($dbc, $query); } if ($comment_id2 != $_GET['comment_id']) { $counter2=1; $query9 = "INSERT INTO comment_likedislike (comment_counter, comment_id) VALUES ('$counter2', '".$_GET['comment_id']."' )"; mysqli_query($dbc, $query9); } }
