  • Problem with UPDATE statement in stored-procedure in Oracle Database

    - by MKP
    Hello, I have stored-procedure in Oracle database like this: create or replace PROCEDURE EDYTUJ_PRACOWNIKA (PR_IMIE IN VARCHAR2, PR_NAZWISKO IN VARCHAR2, PR_PENSJA IN FLOAT, PR_PRZELOZONY IN NUMBER, PR_ODDZIAL IN NUMBER, PRAC_ID IN NUMBER) AS tmpPensja FLOAT := 0; tmpPrzel NUMBER := 0; BEGIN select przelozony into tmpPrzel from pracownik where id = PRAC_ID; IF(tmpPrzel IS NOT NULL) THEN select pensja into tmpPensja from pracownik where id = tmpPrzel; IF(tmpPensja < 1150) THEN UPDATE PRACOWNIK SET pensja = 1000 WHERE id = tmpPrzel; ELSE UPDATE PRACOWNIK SET pensja = pensja - 150 WHERE id = tmpPrzel; (4) END IF; END IF; IF(PR_PRZELOZONY > 0) THEN UPDATE PRACOWNIK SET imie = PR_IMIE, nazwisko = PR_NAZWISKO, pensja = PR_PENSJA, przelozony = PR_PRZELOZONY, oddzial = PR_ODDZIAL WHERE id = PRAC_ID; (2) select pensja into tmpPensja from pracownik where id = PR_PRZELOZONY; IF(tmpPensja > 4850) THEN UPDATE PRACOWNIK SET pensja = 5000 WHERE id = PR_PRZELOZONY; ELSE UPDATE PRACOWNIK SET pensja = pensja + 150 WHERE id = PR_PRZELOZONY; (1) END IF; ELSE UPDATE PRACOWNIK SET imie = PR_IMIE, nazwisko = PR_NAZWISKO, pensja = PR_PENSJA, przelozony = NULL, oddzial = PR_ODDZIAL WHERE ID = PRAC_ID; (3) END IF; END; where przelozony and pensja are columns in pracownik table. And I have problem that when running procedure with parameters that provide that line marked with "(1)" (there is the same problem with line marked with "(4)") should be executed that update statement don't have any effect. What's more statements in lines marked with "(2)" and "(3)" works fine. I have no ideas how to fix it. Thank you in advance for your help.

  • Properly populating tables in an Object Relational database

    - by chaosTechnician
    I've got a homework assignment that requires that I use Oracle 10g Express to implement an Object Relational database to track phone billing data. I have a superclass of Communications with subclasses of Call, Text, and Data. I'm hitting a snag with properly populating these tables so that I can find the appropriate data in the various tables. My Types and Tables are declared as such: create type CommunicationType as object ( -- column names here ) not final; create type CallType under CommunicationType ( -- column names here ); create type TextType under CommunicationType ( -- column names here ); create type DataType under CommunicationType ( -- column names here ); create table Communications of CommunicationType ( -- Primary and Foreign key constraints here ); create table Calls of CallType; create table Texts of TextType; create table Datas of DataType; When I try to insert data into one of the subclasses, its entry doesn't appear in the superclass. Likewise if I insert into the superclass, it doesn't show up in the appropriate subclass. For example, insert into Calls values (CallType( -- Values -- )); doesn't show any data in Communications. Nor does insert into Communications values (CallType( -- Values -- )); show anything in Calls. What am I doing wrong?

  • Ribbon not showing up with dynamically generated ribbon XML from the database

    - by ydobonmai
    I am trying to form ribbon XML with the data from the database and following is what I wrote:- XNamespace xNameSpace = "http://schemas.microsoft.com/office/2006/01/customui"; XDocument document = new XDocument(); document.Add( new XElement (xNameSpace+"customUI" , new XElement("ribbon" , new XElement("tabs")))); // more code to add the groups and the controls with-in the groups ....... // code below to add ribbon XML to the document and to add the relationship RibbonExtensibilityPart ribbonExtensibilityPart = myDoc.AddNewPart<RibbonExtensibilityPart>(); ribbonExtensibilityPart.CustomUI = new DocumentFormat.OpenXml.Office.CustomUI.CustomUI(ribbonXml.ToString()); myDoc.CreateRelationshipToPart(ribbonExtensibilityPart); I don't see any error executing the above. However, when I open the changed document, I dont see my ribbon added. I see following in the CustomUI/CustomUI.xml inside the word:- <?xml version="1.0" encoding="utf-8"?><customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui"> <ribbon xmlns=""> <tabs> ..... I am not sure how the "xmlns" attribute is getting added to the ribbon element. When I remove that attribute, the ribbon gets showed. Could anybody throw any idea on where am I going wrong?

    I have a web application in which I need to fetch data from the database and display in the index page. As you know, asp.net mvc has given options to edit delete etc... I need to populate the page using the conventional DB way and it uses a stored procedure to retrieve results. I dont want to use LINQ.

  • Using reflection to find all linq2sql tables and ensure they match the database

    - by Jake Stevenson
    I'm trying to use reflection to automatically test that all my linq2sql entities match the test database. I thought I'd do this by getting all the classes that inherit from DataContext from my assembly: var contexttypes = Assembly.GetAssembly(typeof (BaseRepository<,>)).GetTypes().Where( t => t.IsSubclassOf(typeof(DataContext))); foreach (var contexttype in contexttypes) { var context = Activator.CreateInstance(contexttype); var tableProperties = type.GetProperties().Where(t=> t.PropertyType.Name == typeof(ITable<>).Name); foreach (var propertyInfo in tableProperties) { var table = (propertyInfo.GetValue(context, null)); } } So far so good, this loops through each ITable< in each datacontext in the project. If I debug the code, "table" is properly instantiated, and if I expand the results view in the debugger I can see actual data. BUT, I can't figure out how to get my code to actually query that table. I'd really like to just be able to do table.FirstOrDefault() to get the top row out of each table and make sure the SQL fetch doesn't fail. But I cant cast that table to be anything I can query. Any suggestions on how I can make this queryable? Just the ability to call .Count() would be enough for me to ensure the entities don't have anything that doesn't match the table columns.

  • SQL connection to database repeating

    - by user175084
    ok now i am using the SQL database to get the values from different tables... so i make the connection and get the values like this: DataTable dt = new DataTable(); SqlConnection connection = new SqlConnection(); connection.ConnectionString = ConfigurationManager.ConnectionStrings["XYZConnectionString"].ConnectionString; connection.Open(); SqlCommand sqlCmd = new SqlCommand("SELECT * FROM Machines", connection); SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd); sqlCmd.Parameters.AddWithValue("@node", node); sqlDa.Fill(dt); connection.Close(); so this is one query on the page and i am calling many other queries on the page. So do i need to open and close the connection everytime...??? also if not this portion is common in all: DataTable dt = new DataTable(); SqlConnection connection = new SqlConnection(); connection.ConnectionString = ConfigurationManager.ConnectionStrings["XYZConnectionString"].ConnectionString; connection.Open(); can i like put it in one function and call it instead.. the code would look cleaner... i tried doing that but i get errors like: Connection does not exist in the current context. any suggestions??? thanks

  • Given the Following List (UL), how can it be serialized and sent to the Database

    - by nobosh
    I have the follow structure which is created with a nested sortable: <UL id="container"> <LI id="main1"> <input type="checkbox" /> Lorem ipsum dolor sit amet, consectetur <UL> <LI id="child2"> <input type="checkbox" /> In hac habitasse platea dictumst. <UL></UL> </LI> </UL> </LI> <LI id="main3"> <input type="checkbox" /> In hac habitasse platea dictumst. <UL></UL> </LI> <LI id="main4"> <input type="checkbox" /> In hac habitasse platea dictumst. <UL></UL> </LI> <LI id="main5"> <input type="checkbox" /> In hac habitasse platea dictumst. <UL></UL> </LI> </UL> Where I'm stuck is how to send this back to the database. I"m guessing that it needs to be serialized, does that sound right to? so that is looks something like: item[]=main1&item[]=221&item_221[]=21&item_221[]=2&item_221[]=211&item[]=22 I'm a little lost at this point and appreciate any tips to move me in the right direction. Thanks, B

  • Database insertion not happening

    - by Pramod Setlur
    int i=0; ContentValues values = null; for ( SortedMap.Entry<Integer, String> entry : mapDefect.entrySet() ) { if( i++ < count ) continue; if( i < arrlst.size() ) { values = new ContentValues(); Log.d("MAP", "Id :"+entry.getKey()+"Des :"+entry.getValue()+"Co :"+ arrlst.get(i)); values.put( MARKER_COORD, arrlst.get( i ) ); values.put( MARKER_ID, entry.getKey() ); values.put( DEFECT_DESCRIPTION, entry.getValue() ); values.put( IMAGE_ID_F, imageID + 1 ); Log.d( "Err", "in insertNewDefectsDescription" ); long rowId = db.insert( TABLE_DEFECTS, null, values ); long rowId1 = rowId; i++; } } So, I want to access the arraylist only after the count variable, which is why the:- if(i++<count) continue; But, when I insert a break point at the 'insert' line, it is not working. The line is not executing at all, and hence the data is not being inserted into the database. What has gone wrong?? The 'values' are null.

  • Database locking: ActiveRecord + Heroku

    - by JP
    I'm building a Sinatra based app for deployment on Heroku. You can imagine it like a standard URL shortener but where old shortcodes expire and become available for new URLs (I realise this is a silly concept but its easier to explain this way). I'm representing the shortcode in my database as an integer and redefining its reader to give a nice short and unique string from the integer. As some rows will be deleted, I've written code that goes thru all the shortcode integers and picks the first free one to use just before_save. Unfortunately I can make my code create two rows with identical shortcode integers if I run two instances very quickly one after another, which is obviously no good! How should I implement a locking system so that I can quickly save my record with a unique shortcode integer? Here's what I have so far: Chars = ('a'..'z').to_a + ('A'..'Z').to_a + ('0'..'9').to_a CharLength = Chars.length class Shorts < ActiveRecord::Base before_save :gen_shortcode after_save :done_shortcode def shortcode i = read_attribute(:shortcode).to_i return '0' if i == 0 s = '' while i > 0 s << Chars[i.modulo(CharLength)] i /= 62 end s end private def gen_shortcode shortcode = 0 self.class.find(:all,:order=>"shortcode ASC").each do |s| if s.read_attribute(:shortcode).to_i != shortcode # Begin locking? break end shortcode += 1 end write_attribute(:shortcode,shortcode) end def done_shortcode # End Locking? end end

  • Adding with PHP to a MySQL database

    I am pretty new to PHP and I am trying to make an inventory database. I have been trying to make it so that a user can enter a card ID and then amount the want to add to the inventory and have it update the inventory. For example someone could type in test and 2342 and it would update test. Here is what I have been trying with no success: add.html <body> <form action="add.php" method="post"> Card ID: <input type="text" name="CardID" /> Amount to Add: <input type="text" name="Add" /> <input type="submit" /> </form> </body> </html> add.php <?php $link = mysql_connect('tulsadir.ipowermysql.com', 'cbouwkamp', '!starman1'); if (!$link){ die('Could not connect: ' . mysql_error()); } mysql_select_db("tdm_inventory", $link); $add = $_POST[Add] mysql_query("UPDATE cardLists SET AmountLeft = '$add' WHERE cardID = 'Test'"); echo "test successful"; mysql_close($link); ?>

  • Not able to insert data in the database from a form in php

  • A little confused about MVC and where to put a database query

    - by jax
    OK, so my Joomla app is in MVC format. I am still a little confused about where to put certain operations, in the Controller or in the Model. This function below is in the controller, it gets called when &task=remove. Should the database stuff be in the Model? It does not seem to fit there because I have two models editapp (display a single application) and allapps (display all the applications), now which one would I put the delete operation in? /** * Delete an application */ function remove() { global $mainframe; $cid = JRequest::getVar( 'cid', array(), '', 'array' ); $db =& JFactory::getDBO(); //if there are items to delete if(count($cid)){ $cids = implode( ',', $cid ); $query = "DELETE FROM #__myapp_apps WHERE id IN ( $cids )"; $db->setQuery( $query ); if (!$db->query()){ echo "<script> alert('".$db->getErrorMsg()."');window.history.go(-1); </script>\n"; } } $mainframe->redirect( 'index.php?option=' . $option . '&c=apps'); } I am also confused about how the flow works. For example, there is a display() function in the controller that gets called by default. If I pass a task, does the display() function still run or does it go directly to the function name passed by $task?

  • Processing a database queue across multiple threads - design advice

    - by rwmnau
    I have a SQL Server table full of orders that my program needs to "follow up" on (call a webservice to see if something has been done with them). My application is multi-threaded, and could have instances running on multiple servers. Currently, every so often (on a Threading timer), the process selects 100 rows, at random (ORDER BY NEWID()), from the list of "unconfirmed" orders and checks them, marking off any that come back successfully. The problem is that there's a lot of overlap between the threads, and between the different processes, and their's no guarantee that a new order will get checked any time soon. Also, some orders will never be "confirmed" and are dead, which means that they get in the way of orders that need to be confirmed, slowing the process down if I keep selecting them over and over. What I'd prefer is that all outstanding orders get checked, systematically. I can think of two easy ways do this: The application fetches one order to check at a time, passing in the last order it checked as a parameter, and SQL Server hands back the next order that's unconfirmed. More database calls, but this ensures that every order is checked in a reasonable timeframe. However, different servers may re-check the same order in succession, needlessly. The SQL Server keeps track of the last order it asked a process to check up on, maybe in a table, and gives a unique order to every request, incrementing its counter. This involves storing the last order somewhere in SQL, which I wanted to avoid, but it also ensures that threads won't needlessly check the same orders at the same time Are there any other ideas I'm missing? Does this even make sense? Let me know if I need some clarification.

  • Saving form values to database after a user logs in

    - by redfalcon
    Hi. We have a form with ratings to submit for a certain restaurant. After the user has entered some values and wants to submit them, we check whether the user is logged in or not. If not, we display a login form and let the user put in his account data and redirect him to the restaurant he wanted to submit a rating for. The problem is, that after he successfully logged in himself, the submitted values are not saved to the database (which works fine if the user is already logged in). So I wondered if it is possible, to somehow save the data although the user is not logged in. I thought of maybe saving the filled values in a variable and have then automatically re-entered after we redirected the user. But I guess this wont work because we use before_filter :login_required, :only => [ :create ] So we couldnt even access the filled in values, since we display the login-form before the method has processed the values in the form, right? Any idea how we can make rails to save the values or at least have them automatically re-entered to the form? Thanks!

My code: <?php function display($column,$rows) { echo "<table border='1' align='center'>"; for ($iii = 0;$iii <$_POST['column'];$iii++) { echo "<tr>".$jjj."</tr>"; //display no. of <tr> for ($jjj = 0; $jjj <$_POST['rows'];$jjj++) { echo "<td>" ."<input type=\"text\" name='$iii'>"."</td>"; } } echo "</table>"; } ?>

  • database design - empty fields

    - by imanc
    Hey, I am currently debating an issue with a guy on my dev team. He believes that empty fields are bad news. For instance, if we have a customer details table that stores data for customers from different countries, and each country has a slightly different address configuration - plus 1-2 extra fields, e.g. French customer details may also store details for entry code, and floor/level plus title fields (madamme, etc.). South Africa would have a security number. And so on. Given that we're talking about minor variances my idea is to put all of the fields into the table and use what is needed on each form. My colleague believes we should have a separate table with extra data. E.g. customer_info_fr. But this seams to totally defeat the purpose of a combined table in the first place. His argument is that empty fields / columns is bad - but I'm struggling to find justification in terms of database design principles for or against this argument and preferred solutions. Another option is a separate mini EAV table that stores extra data with parent_id, key, val fields. Or to serialise extra data into an extra_data column in the main customer_data table. I think I am confused because what I'm discussing is not covered by 3NF which is what I would typically use as a reference for how to structure data. So my question specifically: - if you have slight variances in data for each record (1-2 different fields for instance) what is the best way to proceed?
