  • Mocking ISession.Query<T>() for testing consumer

    - by TheCloudlessSky
    I'm trying to avoid using an in memory database for testing (though I might have to do this if the following is impossible). I'm using NHibernate 3.0 with LINQ. I'd like to be able to mock session.Query<T>() to return some dummy values but I can't since it's an extension method and these are pretty much impossible to test. Does anyone have any suggestions (other than using an in memory database) for testing session queries with LINQ?

  • Check value existance while performing a UPDATE query

    - by nimo
    Hi, I need to perform a simple update query where the update should only be done, if there is no value with updating value (item_name). For example, DB table [item_types] item_id(PK) | item_name Assuming there exist item_id with 6, My attempt is UPDATE item_types as k SET k.item_name = 'item_1' WHERE NOT EXISTS (SELECT * FROM item_types as a WHERE a.item_name = 'item_1') AND k.item_id = '6' But this gives me error "You can't specify target table 'k' for update in FROM clause" Could you please explain the error here and how can I achieve this ? Thank you

  • Change query to use a LEFT join

    - by Craig
    I have a query which is failing, as it needs to be using LEFT JOIN, as opposed to the default INNER JOIN used by the 'join' syntax: var users = (from u in this._context.Users join p in this._context.Profiles on u.ProfileID equals p.ID join vw in this._context.vw_Contacts on u.ContactID equals vw.ID orderby u.Code select new { ID = u.ID, profileId = p.ID, u.ContactID, u.Code, u.UserName, vw.FileAs, p.Name, u.LastLogout, u.Inactive, u.Disabled }).ToList(); How would i re-write this so that is utilises a LEFT join?

  • Update query not effecting all rows in database

    - by Webnet
    I have the following query.... UPDATE vehicle_catalog SET parent_id = 0 WHERE parent_id = SUBSTR(id, 0, 5) I need to set all parent_ids to 0 where the first 5 characters of id is the same as the parent_id. This is effecting 0 rows when I'm looking at the data and it should be effecting over 10,000. Any ideas on why this wouldn't be effecting all rows?

  • How to add new filters to CAML queries in SharePoint 2007

CAML it’s a markup language like html that allows developers to do queries against SharePoint lists, it’s syntax is very easy to understand and it allows to add logical conditions like Where, Contains, And, Or, etc, just like a SQL Query. For one of our projects we have the need to do a filter on SharePoint views, the problem here is that the view it’s a list containing a CAML Query with the filters the view may have, so in order to filter the view that’s already been filtered before, we need to append our filters to the existing CAML Query. That’s not a trivial task because the where statement in a CAML Query it’s like this: <Where>   <And>     <Filter1 />     <Filter2 />   </And> </Where> If we want to add a new logical operator, like an OR it’s not just as simple as to append the OR expression like the following example: <Where>   <And>     <Filter1 />     <Filter2 />   </And>   <Or>     <Filter3 />   </Or> </Where> But instead the correct query would be: <Where>   <Or>     <And>       <Filter1 />       <Filter2 />     </And>     <Filter3 />   </Or> </Where> Notice that the <Filter# /> tags are for explanation purpose only. In order to solve this problem we created a simple component, it has a method that receives the current query (could be an empty query also) and appends the expression you want to that query. Example: string currentQuery = @“ <Where>    <And>     <Contains><FieldRef Name='Title' /><Value Type='Text'>A</Value></Contains>     <Contains><FieldRef Name='Title' /><Value Type='Text'>B</Value></Contains>   </And> </Where>”; currentQuery = CAMLQueryBuilder.AppendQuery(     currentQuery,     “<Contains><FieldRef Name='Title' /><Value Type='Text'>C</Value></Contains>”,     CAMLQueryBuilder.Operators.Or); The fist parameter this function receives it’s the actual query, the second it’s the filter you want to add, and the third it’s the logical operator, so basically in this query we want all the items that the title contains: the character A and B or the ones that contains the character C. The result query is: <Where>   <Or>      <And>       <Contains><FieldRef Name='Title' /><Value Type='Text'>A</Value></Contains>       <Contains><FieldRef Name='Title' /><Value Type='Text'>B</Value></Contains>     </And>     <Contains><FieldRef Name='Title' /><Value Type='Text'>C</Value></Contains>   </Or> </Where>     The code:   First of all we have an enumerator inside the CAMLQueryBuilder class that has the two possible Options And, Or. public enum Operators { And, Or }   Then we have the main method that’s the one that performs the append of the filters. public static string AppendQuery(string containerQuery, string logicalExpression, Operators logicalOperator){   In this method the first we do is create a new XmlDocument and wrap the current query (that may be empty) with a “<Query></Query>” tag, because the query that comes with the view doesn’t have a root element and the XmlDocument must be a well formatted xml.   XmlDocument queryDoc = new XmlDocument(); queryDoc.LoadXml("<Query>" + containerQuery + "</Query>");   The next step is to create a new XmlDocument containing the logical expression that has the filter needed.   XmlDocument logicalExpressionDoc = new XmlDocument(); logicalExpressionDoc.LoadXml("<root>" + logicalExpression + "</root>"); In these next four lines we extract the expression from the recently created XmlDocument and create an XmlElement.                  XmlElement expressionElTemp = (XmlElement)logicalExpressionDoc.SelectSingleNode("/root/*"); XmlElement expressionEl = queryDoc.CreateElement(expressionElTemp.Name); expressionEl.InnerXml = expressionElTemp.InnerXml;   Below are the main steps in the component logic. The first “if” checks if the actual query doesn’t contains a “Where” clause. In case there’s no “Where” we add it and append the expression.   In case that there’s already a “Where” clause, we get the entire statement that’s inside the “Where” and reorder the query removing and appending elements to form the correct query, that will finally filter the list.   XmlElement whereEl; if (!containerQuery.Contains("Where")) { queryDoc.FirstChild.AppendChild(queryDoc.CreateElement("Where")); queryDoc.SelectSingleNode("/Query/Where").AppendChild(expressionEl); } else { whereEl = (XmlElement)queryDoc.SelectSingleNode("/Query/Where"); if (!containerQuery.Contains("<And>") &&                 !containerQuery.Contains("<Or>"))        {              XmlElement operatorEl = queryDoc.CreateElement(GetName(logicalOperator)); XmlElement existingExpression = (XmlElement)whereEl.SelectSingleNode("/Query/Where/*"); whereEl.RemoveChild(existingExpression);                 operatorEl.AppendChild(existingExpression);               operatorEl.AppendChild(expressionEl);                 whereEl.AppendChild(operatorEl);        }        else        {              XmlElement operatorEl = queryDoc.CreateElement(GetName(logicalOperator)); XmlElement existingOperator = (XmlElement)whereEl.SelectSingleNode("/Query/Where/*");                 whereEl.RemoveChild(existingOperator);               operatorEl.AppendChild(existingOperator);               operatorEl.AppendChild(expressionEl);                 whereEl.AppendChild(operatorEl);         }  }  return queryDoc.FirstChild.InnerXml }     Finally the GetName method converts the Enum option to his string equivalent.   private static string GetName(Operators logicalOperator) {       return Enum.GetName(typeof(Operators), logicalOperator); }        Normal 0 21 false false false ES-UY X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Normal 0 21 false false false ES-UY X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} This component helped our team a lot using SharePoint 2007 and modifying the queries, but now in SharePoint 2010; that wouldn’t be needed because of the incorporation of LINQ to SharePoint.

  • Legacy URL rewriting with query string parameters

    - by John Kaster
    I've looked at http://stackoverflow.com/questions/817325/asp-net-mvc-routing-legacy-urls-passing-querystring-ids-to-controller-actions and several other similar posts for legacy URL routing, but I can't get past the error "The RouteData must contain an item named 'controller' with a non-empty string value." Looking this up on line didn't give me any hints to solve my problem. I've implemented the Legacy routing class described in the link above, and this is what I've defined in the routing table: routes.Add( "Legacy", new LegacyRoute("fooref.aspx", "FooRef", new LegacyRouteHandler()) ); routes.MapRoute( "FooRef", "{controller}/{action}", new { controller = "Home", action = "Index", foo_id = UrlParameter.Optional, bar_id = UrlParameter.Optional } ); When I use Phil Haack's route debugger, it indicates that fooref.aspx has a match, but when I turn the route debugger off, I get the error above. If I reverse the statement order, I get "Resource not found" for /ctprefer.aspx, which makes sense -- so it appears to be finding that as a valid route when put in the other order. Where do I need to declare this missing controller reference? Have routing requirements changed for ASP.NET MVC 2 RTM?

  • How to make sql query dynamic?

    - by ClarkSKent
    Hello, I am using this pagination class and was looking for a way to make the sql query more dynamic instead of having it hardcoded. I have a 3 <li> elements that I want to be filter buttons, meaning when a user clicks on one of these elements I want It to send the id so I can use it in a sql query. So for the $sql = "select * from explore where category='marketing'"; (as seen below). When the user clicks on the 'automotive' button it will change the category above to automotive. Any help on this would be highly appreciated, Thanks. This is what my main page looks like: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_page.js"></script> <?php //Include the PS_Pagination class include('ps_pagination.php'); //Connect to mysql db $conn = mysql_connect('localhost', 'root', 'root'); mysql_select_db('ajax_demo',$conn); $sql = "select * from explore where category='marketing'"; //Create a PS_Pagination object $pager = new PS_Pagination($conn, $sql, 3, 11, 'param1=valu1&param2=value2'); //The paginate() function returns a mysql //result set for the current page $rs = $pager->paginate(); //Loop through the result set while($row = mysql_fetch_assoc($rs)) { echo "<table width='800px'>"; echo "<tr>"; echo"<td>"; echo $row['id']; echo"</td>"; echo"<td>"; echo $row['site_description']; echo"</td>"; echo"<td>"; echo $row['site_price']; echo"</td>"; echo "</tr>"; echo "</table>"; } echo "<ul id='pagination'>"; echo "<li>"; //Display the navigation echo $pager->renderFullNav(); echo "</li>"; echo "</ul>"; echo "<ul id='filter'>"; echo "<li id='marketing'>"; echo "Marketing"; echo "</li>"; echo "<li id='automotive'>"; echo "Automotive"; echo "</li>"; echo "<li id='sports'>"; echo "Sports"; echo "</li>"; echo "</ul>"; ?>

  • What's the most efficient query?

    - by Aaron Carlino
    I have a table named Projects that has the following relationships: has many Contributions has many Payments In my result set, I need the following aggregate values: Number of unique contributors (DonorID on the Contribution table) Total contributed (SUM of Amount on Contribution table) Total paid (SUM of PaymentAmount on Payment table) Because there are so many aggregate functions and multiple joins, it gets messy do use standard aggregate functions the the GROUP BY clause. I also need the ability to sort and filter these fields. So I've come up with two options: Using subqueries: SELECT Project.ID AS PROJECT_ID, (SELECT SUM(PaymentAmount) FROM Payment WHERE ProjectID = PROJECT_ID) AS TotalPaidBack, (SELECT COUNT(DISTINCT DonorID) FROM Contribution WHERE RecipientID = PROJECT_ID) AS ContributorCount, (SELECT SUM(Amount) FROM Contribution WHERE RecipientID = PROJECT_ID) AS TotalReceived FROM Project; Using a temporary table: DROP TABLE IF EXISTS Project_Temp; CREATE TEMPORARY TABLE Project_Temp (project_id INT NOT NULL, total_payments INT, total_donors INT, total_received INT, PRIMARY KEY(project_id)) ENGINE=MEMORY; INSERT INTO Project_Temp (project_id,total_payments) SELECT `Project`.ID, IFNULL(SUM(PaymentAmount),0) FROM `Project` LEFT JOIN `Payment` ON ProjectID = `Project`.ID GROUP BY 1; INSERT INTO Project_Temp (project_id,total_donors,total_received) SELECT `Project`.ID, IFNULL(COUNT(DISTINCT DonorID),0), IFNULL(SUM(Amount),0) FROM `Project` LEFT JOIN `Contribution` ON RecipientID = `Project`.ID GROUP BY 1 ON DUPLICATE KEY UPDATE total_donors = VALUES(total_donors), total_received = VALUES(total_received); SELECT * FROM Project_Temp; Tests for both are pretty comparable, in the 0.7 - 0.8 seconds range with 1,000 rows. But I'm really concerned about scalability, and I don't want to have to re-engineer everything as my tables grow. What's the best approach?

  • JPA + EJB + JSF: how can design complicated query

    - by Harry Pham
    I am using netbean 6.8 btw. Let say that I have 4 different tables: Company, Facility, Project, and Document. So the relationship is this. A company can have multiple facilities. A facility can have multiple projects, and a project can have multiple documents. Company: +companyNum: PK +facilityNum: FK Facility: +facilityNum: PK +projectNum: FK Project: +projectNum: PK +drawingNum: FK So when I create Entity Class From Database in netbean 6.8, I have 4 entity classes that named after the above 4 tables. So if I want to see all the Document in the database, then it is easy. In my SessionBean, I would do this: @PersistenceContext private EntityManager em; List<Document> documents = em.createNamedQuery("Document.findAll").getResultList(); However, that is not all what I need. Let say that I want to know all the Document from a particular Company, or all the Document from a particular Project from a particular Facility from a particular Company. I am very new to JPA + EJB + JSF as a whole. Please help me out.

  • Basic SQL Query, I am newbie

    - by user3530547
    I just started my database and query class on Monday. We met on Monday and just went over the syllabus, and on Wednesday the network at school was down so we couldn't even do the power point lecture. Right now I am working on my first homework assignment and I am almost finished but I am having trouble on one question. Here is is... Write a SELECT statement that returns one column from the Customers table named FullName that joins the LastName and FirstName columns. Format the columns with the last name, a comma, a space, and the first name like this: Doe, John Sort the result set by last name in ascending sequence. Return only the contacts whose last name begins with letters from M to Z. Here is what I have so far... USE md0577283 SELECT FirstName,LastName FROM Customers ORDER BY LastName,FirstName My question is how do I format is Lastname, FirstName like the professor wants and how do I only select names M-Z? If someone could point me in the right direction I would greatly appreciate it. Thank you. PS With all do respect, I didn't ask for the answer I asked for a nudge in the right direction so why the down vote guys?

  • Why won't C# accept a (seemingly) perfectly good Sql Server CE Query?

    - by VoidKing
    By perfectly good sql query, I mean to say that, inside WebMatrix, if I execute the following query, it works to perfection: SELECT page AS location, (len(page) - len(replace(UPPER(page), UPPER('o'), ''))) / len('o') AS occurences, 'pageSettings' AS tableName FROM PageSettings WHERE page LIKE '%o%' UNION SELECT pageTitle AS location, (len(pageTitle) - len(replace(UPPER(pageTitle), UPPER('o'), ''))) / len('o') AS occurences, 'ExternalSecondaryPages' AS tableName FROM ExternalSecondaryPages WHERE pageTitle LIKE '%o%' UNION SELECT eventTitle AS location, (len(eventTitle) - len(replace(UPPER(eventTitle), UPPER('o'), ''))) / len('o') AS occurences, 'MainStreetEvents' AS tableName FROM MainStreetEvents WHERE eventTitle LIKE '%o%' Here i am using 'o' as a static search string to search upon. No problem, but not exeactly very dynamic. Now, when I write this query as a string in C# and as I think it should be (and even as I have done before) I get a server-side error indicating that the string was not in the correct format. Here is a pic of that error: And (although I am only testing the output, should I get it to quit erring), here is the actual C# (i.e., the .cshtml) page that queries the database: @{ Layout = "~/Layouts/_secondaryMainLayout.cshtml"; var db = Database.Open("Content"); string searchText = Request.Unvalidated["searchText"]; string selectQueryString = "SELECT page AS location, (len(page) - len(replace(UPPER(page), UPPER(@0), ''))) / len(@0) AS occurences, 'pageSettings' AS tableName FROM PageSettings WHERE page LIKE '%' + @0 + '%' "; selectQueryString += "UNION "; selectQueryString += "SELECT pageTitle AS location, (len(pageTitle) - len(replace(UPPER(pageTitle), UPPER(@0), ''))) / len(@0) AS occurences, 'ExternalSecondaryPages' AS tableName FROM ExternalSecondaryPages WHERE pageTitle LIKE '%' + @0 + '%' "; selectQueryString += "UNION "; selectQueryString += "SELECT eventTitle AS location, (len(eventTitle) - len(replace(UPPER(eventTitle), UPPER(@0), ''))) / len(@0) AS occurences, 'MainStreetEvents' AS tableName FROM MainStreetEvents WHERE eventTitle LIKE '%' + @0 + '%'"; @:beginning <br/> foreach (var row in db.Query(selectQueryString, searchText)) { @:entry @:@row.location &nbsp; @:@row.occurences &nbsp; @:@row.tableName <br/> } } Since it is erring on the foreach (var row in db.Query(selectQueryString, searchText)) line, that heavily suggests that something is wrong with my query, however, everything seems right to me about the syntax here and it even executes to perfection if I query the database (mind you, un-parameterized) directly. Logically, I would assume that I have erred somewhere with the syntax involved in parameterizing this query, however, my double and triple checking (as well as, my past experience at doing this) insists that everything looks fine here. Have I messed up the syntax involved with parameterizing this query, or is something else at play here that I am overlooking? I know I can tell you, for sure, as it has been previously tested, that the value I am getting from the query string is, indeed, what I would expect it to be, but as there really isn't much else on the .cshtml page yet, that is about all I can tell you.

  • Query.fetch(limit=2000) only moves cursor forward by 1000 entities?

    - by Liron
    Let's say I have 2500 MyModel entities in my datastore, and I run this code: query = MyModel.all() first_batch = query.fetch(2000) len(first_batch) # 2000 next_query = MyModel.all().with_cursor(query.cursor()) next_batch = next_query.fetch(2000) What do you think len(next_batch) is? 500, right? Nope - it's 1500. Apparently the query cursor never moves forward by more than 1000, even when the query itself returns more than 1000 entities. Should I do something different or is it just an App Engine bug?

  • Use LINQ to query nested OData collection

    - by Kyle Russell
    I'm playing around with the new Netflix OData feed (http://odata.netflix.com/Catalog/) and having some issues. I'm trying to learn LINQ at the same time but having difficulty doing what I thought was going to be quite simple. I'd like to return a list of Titles that match a given Genre. The Titles object contains a collection of Genres. I'm not sure how to write this query. My attempt below does not appear to work using LINQPad. from t in Titles where t.Genres.Name.Contains("ABC") select t
