    - by Daniel
    I've got a string like this in my Excel VBA: strSQL = "SELECT * FROM Total WHERE (SimulationID = (" & TextBox1.Text & ") And Test1 = (" & Example & "))" However, sometimes Test will be 'is null', which makes the query And Example = is NULL How can I change it to add an if/then statement or something to make it say And Example is null when Example has a value of "is null"?

  • Performance in SQL Mobile with one big column that's not being selected

    - by Anthony Mastrean
    I have a SQL Mobile database with one table. It has several columns with useful, often queried data and one column that stores a relatively large string per record (1000+ characters) that is not queried often. Imagine this fake schema, the "lifeStory" field is the large one. table1 String firstName String lastName String address String lifeStory A representative query would be SELECT firstName, lastName, address FROM table1 WHERE firstName = :p1 Does anyone know of any performance concerns leaving that large, infrequently queried column in this table?

  • Problem in loading cities using JSON

    - by Saravanan I M
    I am using Geonames for loading the cities using JSON. Geonames data i imported into my database. I am using MS SQL 2008 Server. I display a dropdown for country select. Once the user select the country. I am loading all the cities into the autocomplete textbox. I am facing a delay in the getJSON method. Also it seems like executing asynchronous. So before getting all the data my autocompelte is getting filled. Below is my complete script. I think i have some problem in the loop. Please advice me what i am doing wrong in my code. $(document).ready(function () { $("#ShowLoad").hide(); //Hook onto the MakeID list's onchange event $("#Country").change(function () { findcities = []; $("#ShowLoad").show(); $("#HomeTown").unautocomplete(); var url = '<%= Url.Content("~/") %>' + "Location/GetCitiesCountByCountry/" + $("#Country").val(); $.getJSON(url, null, function (data) { var total = data; if (total > 0) { var pageTotal = Math.ceil(total / 1000); var isFilled = false; for (var i = 0; i < pageTotal; i++) { var skip = i == 1 ? 0 : (i * 1000) - 1000; var url = '<%= Url.Content("~/") %>' + "Location/GetCitiesByCountry/" + $("#Country").val() + "?skip=" + skip; //alert(i); $.getJSON(url, null, function (data) { $.each(data.Cities, function (index, optionData) { if ($("#Country").val() == "US") { findcities.push(optionData.asciiname + "," + optionData.admin1_code); } else { findcities.push(optionData.asciiname); } }); if (i == pageTotal) { //alert(findcities); $("#ShowLoad").hide(); $("#HomeTown").focus().autocomplete(findcities); } }); } $("#HomeTown").setOptions({ max: 100000 }); } }); }).change(); });

  • Hibernate mapping to object that already exists

    - by teehoo
    I have two classes, ServiceType and ServiceRequest. Every ServiceRequest must specify what kind of ServiceType it is. All ServiceType's are predefined in the database, and ServiceRequest is created at runtime by the client. Here are my .hbm files: <hibernate-mapping> <class dynamic-insert="false" dynamic-update="false" mutable="true" name="xxx.model.entity.ServiceRequest" optimistic-lock="version" polymorphism="implicit" select-before-update="false"> <id column="USER_ID" name="id"> <generator class="native"/> </id> <property name="quantity"> <column name="quantity" not-null="true"/> </property> <many-to-one cascade="all" class="xxx.model.entity.ServiceType" column="service_type" name="serviceType" not-null="false" unique="false"/> </class> </hibernate-mapping> and <hibernate-mapping> <class dynamic-insert="false" dynamic-update="false" mutable="true" name="xxx.model.entity.ServiceType" optimistic-lock="version" polymorphism="implicit" select-before-update="false"> <id column="USER_ID" name="id"> <generator class="native"/> </id> <property name="description"> <column name="description" not-null="false"/> </property> <property name="cost"> <column name="cost" not-null="true"/> </property> <property name="enabled"> <column name="enabled" not-null="true"/> </property> </class> </hibernate-mapping> When I run this, I get com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails I think my problem is that when I create a new ServiceRequest object, ServiceType is one of its properties, and therefore when I'm saving ServiceRequest to the database, Hibernate attempts to insert the ServiceType object once again, and finds that it is already exists. If this is the case, how do I make it so that Hibernate points to the exists ServiceType instead of trying to insert it again?

  • Mysql Left Join Null Result

    - by Ozzy
    I have this query SELECT articles.*, users.username AS `user` FROM `articles` LEFT JOIN `users` ON articles.user_id = users.id ORDER BY articles.timestamp Basically it returns the list of articles and the username that the article is associated to. Now if there is no entry in the users table for a particular user id, the users var is NULL. Is there anyway to make it that if its null it returns something like "User Not Found"? or would i have to do this using php?

  • Complicted ActiveRecord Association. Going through a 4th table

    - by Dex
    I have kind of a complicated case and am wondering how this would work in rails: I want to categories the genres of some singers. Singers can belong to more than one genres, and users can assign tags to each genre For example: singers <-- singers_genres -- genres <-- genres_tags -- tags SQL would look something like: SELECT * FROM singers S INNER JOIN singers_genres SG ON S.id=SG.singer_id INNER JOIN genres G ON G.id = SG.genre_id LEFT OUTER JOIN genre_tags GT ON G.id = GT.genre_id INNER JOIN tags T ON GT.tag_id = T.id

  • I need help with creating a data structure in PHP

    - by alex
    What I need to do is have a data structure that shows jobs organised into 14 day periods, but only when an id is the same. I've implemented all sorts of stuff, but they have failed miserably. Ideally, maybe a SQL expert could handle all of this in the query. Here is some of my code. You can assume all library stuff works as expected. $query = 'SELECT date, rig_id, comments FROM dor ORDER BY date DESC'; $dors = Db::query(Database::SELECT, $query)->execute()->as_array(); This will return all jobs, but I need to have them organised by 14 day period with the same rig_id value. $hitches = array(); foreach($dors as $dor) { $rigId = $dor['rig_id']; $date = strtotime($dor['date']); if (empty($hitches)) { $hitches[] = array( 'rigId' => $rigId, 'startDate' => $date, 'dors' => array($dor) ); } else { $found = false; foreach($hitches as $key => $hitch) { $hitchStartDate = $hitch['startDate']; $dateDifference = abs($hitchStartDate - $date); $isSameHitchTimeFrame = $dateDifference < (Date::DAY * 14); if ($rigId == $hitch['rigId'] AND $isSameHitchTimeFrame) { $found = true; $hitches[$key]['dors'][] = $dor; } } if ($found === false) { $hitches[] = array( 'rigId' => $rigId, 'startDate' => $date, 'dors' => array($dor) ); } } } This seems to work OK splitting up by rig_id, but not by date. I also think I'm doing it wrong because I need to check the earliest date. Is it possible at all to do any of this in the database query? To recap, here is my problem I have a list of jobs with all have a rig_id (many jobs can have the same) and a date. I need the data to be organised into hitches. That is, the rig_id must be the same per hitch, and they must span a 14 day period, in which the next 14 days with the same rig_id will be a new hitch. Can someone please point me on the right track? Cheers

    What are the possible causes of this type of error - "[Microsoft][ODBC SQL Server Driver]Protocol error in TDS stream"? And how can this be fixed? My application runs in C++ calling stored procedures implemented in SQL Server. There's this one SP (containing select and update statements) that causes this problem, after which all succeeding queries will return that the cursor is in an invalid state. I've checked the SP but I don't see any possible problem.
