• Assign values from same table

  - by Reddy S R

  I have a database table with parent child relationships between different rows. 1 parent can have any number of children. Children do not have children. I want to copy 'Message' from 'Parent Category' to child categories. CategoryID Name Value Message ParentID DeptId 1 Books 9 Specials 1 2 Music 7 1 3 Paperback 25 1 1 4 PDFs 26 1 2 5 CDs 35 2 1 If that was sample data, Paperback should have Specials as it's Message after the query is run. I have gotten the child rows (the query runs very slow, don't know why), but how do I get the data and assign it to appropriate child rows? --@DeptId = 1 select * from Categories where ParentID in( select CategoryID from Categories where DeptID = @DeptId ) I would like to see a solution that would not use cursors. Thanks

• update table with information from IDirectory

  - by sue

  I have a table with 4 columns, LoginID, LastName, FirstName, Email. The data for LoginID was populated from an other table. I have to write a small routine to update this table, by sending in the LoginID and with help of IDirectory routines, get the Lastname, firstname and email. This is what i'm attempting to do, but getting confused with the right syntax. using (TSADRequestEntities context = UnityHelper.Resolve()) { var fpvalues = context.FOCALPOINTs.ToList(); foreach (var item in fpvalues) { IEnumerable<UserInfo> query = UnityHelper.Resolve<IUserDirectory>().Search(item.LoginID); //Here, FocalPoint is the table that has the loginID and the other fields //I need to update. the query shld now hv info on lastname etc..how do I //retrieve that value and update the table? } }

• MySQL Dynamicly determine the tabel to use with inner join

  - by user366990

  He guys, I'm stuck with a problem and I hope someone can help me out. I have a date. For example 2009-10-1. This date is used to check in which season I am working. This could be summer or winter. If whe are in the summer the table to use for my inner join whould be 'summer09_rooms'. If winter 'winter09_rooms'. So I basicly whant to do a CASE WHEN in my INNER JOIN. How to accomplish this. The query would look like this: SELECT name, arrival_date, departure_date FROM holliday a INNER JOIN ( CASE when arrival_date BETWEEN 2009-10-1 AND 2009-4-1 THEN summer09_rooms b ELSE winter09_rooms b END ) ON a.dossier=b.dossier Of course this query isn't working but now I hope you'l see what I want to accomplish. Kind regards, Digital Human

• Paging in SQL Server problems

  - by Manh Trinh

  I have searched for paging in SQL Server. I found most of the solution look like that What is the best way to paginate results in SQL Server But it don't meet my expectation. Here is my situation: I work on JasperReport, for that: to export the report I just need pass the any Select query into the template, it will auto generated out the report EX : I have a select query like this: Select * from table A I don't know any column names in table A. So I can't use Select ROW_NUMBER() Over (Order By columsName) And I also don't want it order by any columns. Anyone can help me do it? PS: In Oracle , it have rownum very helpful in this case. Select * from tableA where rownum > 100 and rownum <200 Paging with Oracle

• for loop with count from array, limit output? PHP

  - by Philip

  print '<div id="wrap">'; print "<table width=\"100%\" border=\"0\" align=\"center\" cellpadding=\"3\" cellspacing=\"3\">"; for($i=0; $i<count($news_comments); $i++) { print ' <tr> <td width="30%"><strong>'.$news_comments[$i]['comment_by'].'</strong></td> <td width="70%">'.$news_comments[$i]['comment_date'].'</td> </tr> <tr> <td></td> <td>'.$news_comments[$i]['comment'].'</td> </tr> '; } print '</table></div>'; $news_comments is a 3 diemensional array from mysqli_fetch_assoc returned from a function elsewhere, for some reason my for loop returns the total of the array sets such as [0][2] etc until it reaches the max amount from the counted $news_comments var which is a return function of LIMIT 10. my problem is if I add any text/html/icons inside the for loop it prints it in this case 11 times even though only array sets 1 and 2 have data inside them. How do I get around this? My function query is as follows: function news_comments() { require_once '../data/queries.php'; // get newsID from the url $urlID = $_GET['news_id']; // run our query for newsID information $news_comments = selectQuery('*', 'news_comments', 'WHERE news_id='.$urlID.'', 'ORDER BY comment_date', 'DESC', '10'); // requires 6 params // check query for results if(!$news_comments) { // loop error session and initiate var foreach($_SESSION['errors'] as $error=>$err) { print htmlentities($err) . 'for News Comments, be the first to leave a comment!'; } } else { print '<div id="wrap">'; print "<table width=\"100%\" border=\"0\" align=\"center\" cellpadding=\"3\" cellspacing=\"3\">"; for($i=0; $i<count($news_comments); $i++) { print ' <tr> <td width="30%"><strong>'.$news_comments[$i]['comment_by'].'</strong></td> <td width="70%">'.$news_comments[$i]['comment_date'].'</td> </tr> <tr> <td></td> <td>'.$news_comments[$i]['comment'].'</td> </tr> '; } print '</table></div>'; } }// End function Any help is greatly appreciated.

• Is SELECT INTO able to affect data from its original table during UPDATE

  - by driveby

  Whilst asking this question asp.net scheduling timed events user murph posted some insightful information: Point about this is that its very, very simple - you have an process for exchange that is performing a clearly defined task and you have a high frequency task that is not doing anything particularly complex, its a straightforward query (select from table where sent = false and send at < value) - probably into temporary table so that you can run a single query update after you've done the sends - that you can optimise the index for. You're not trying to queue up a huge pile of event triggers, just one that fires once a minute and processes things that are due. Is it possible to SELECT data from table X INTO table Y and have the UPDATES that are performed on table Y pushed into table X? I guess the alternative would be that the data gets updated in table Y then an update command can be run on table X based on the data in table Y. What would be the advantage of selecting into another table? Thank you,

• Grails: Querying Associations causes groovy.lang.MissingMethodException

• SQL join to grab data from same table via intermediate table

  - by Sergio

  Hi Could someone help me with building the following query. I have a table called Sites, and one called Site_H. The two are joined by a foreign key relationship on page_id. So the Sites table contains pages, and the Site_H table shows which pages any given page is a child of by having another foreign key relation back to the site table with a column called ParentOf. So, a page can be have another page as a parent. Other data is stored in the Site_H table such as position etc, hence why it is separated out. I would like a query that returns the details of a page along with the details of its parent page. I just cant quite think about how to structure the SQL. Thanks

• Gotchas INSERTing into SQLite on Android?

  - by paul.meier

  Hi friends, I'm trying to set up a simple SQLite database in Android, handling the schema via a subclass of SQLiteOpenHelper. However, when I query my tables, the columns I think I've inserted are never present. Namely, in SQLiteOpenHelper's onCreate(SQLiteDatabase db) method, I use db.execSQL() to run CREATE TABLE commands, then have tried both db.execSQL and db.insert() to run INSERT commands on the tables I've just created. This appears to run fine, but when I try to query them I always get 0 rows returned (for debugging, the queries I'm running are simple SELECT * FROM table and checking the Cursor's getCount()). Anybody run into anything like this before? These commands seem to run on command-line sqlite3. Are they're gotchas that I'm missing (e.g. INSERTS must/must not be semicolon terminated, or some issue involving multiple tables)? I've attached some of the code below. Thanks for your time, and let me know if I can clarify further. @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE "+ LEVEL_TABLE +" (" + " "+ _ID +" INTEGER PRIMARY KEY AUTOINCREMENT," + " level TEXT NOT NULL,"+ " rows INTEGER NOT NULL,"+ " cols INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ DYNAMICS_TABLE +" (" + " level_id INTEGER NOT NULL," + " row INTEGER NOT NULL,"+ " col INTEGER NOT NULL,"+ " type INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ SCORE_TABLE +" (" + " level_id INTEGER NOT NULL," + " score INTEGER NOT NULL,"+ " date_achieved DATE NOT NULL,"+ " name TEXT NOT NULL);"); this.enterFirstLevel(db); } And a sample of the insert code I'm currently using, which gets called in enterFirstLevel() (some values hard-coded just to get it running...): private void insertDynamic(SQLiteDatabase db, int row, int col, int type) { ContentValues values = new ContentValues(); values.put("level_id", "1"); values.put("row", Integer.toString(row)); values.put("col", Integer.toString(col)); values.put("type", Integer.toString(type)); db.insertOrThrow(DYNAMICS_TABLE, "col", values); } Finally, query code looks like this: private Cursor fetchLevelDynamics(int id) { SQLiteDatabase db = this.leveldata.getReadableDatabase(); try { String fetchQuery = "SELECT * FROM " + DYNAMICS_TABLE; String[] queryArgs = new String[0]; Cursor cursor = db.rawQuery(fetchQuery, queryArgs); Activity activity = (Activity) this.context; activity.startManagingCursor(cursor); return cursor; } finally { db.close(); } }

• How do I find the largest factor of an integer in mysql

• MySQL break out group clause from subquery

  Here is my query SELECT COALESCE(js.name,'Lead saknas'), count(j.id) FROM jobs j LEFT JOIN job_sources js ON j.job_source=js.id LEFT JOIN (SELECT * FROM quotes GROUP BY job_id) q ON j.id=q.job_id GROUP BY j.job_source The problem is that it's allowed for each job to have more than one quote. Because of that i group the quotes by job_id. Now sure, this works. But i don't like the solution with a subquery. How can i break out the group clause from the subquery to the main query? I have tried to add q.job_id to the main group clause, both before and after the existing one but don't get the same results.

• c# const in jQuery?

  - by Cristian Boariu

  Hi guys, I have this piece of code in javascript: var catId = $.getURLParam("category"); In my asp.net and c# code for "category" query string i use a public const: public const string CATEGORY = "category"; so if i want to change the query string parameter to be "categoryTest" i only change this const and all the code is updated. Now the question is: how can i do something similar for the javascript i have in the same application (so i want to use the same constant)? I mean i want something like this: var catId = $.getURLParam(CQueryStringParameters.CATEGORY); but because there are none asp.net tags, my const is not interpreted... Any workaround?

• Left Join Returning Extra Rows T-SQL?

  - by davemackey

  I have the following query: select * from ACADEMIC a left join RESIDENCY r on a.PEOPLE_CODE_ID = r.PEOPLE_CODE_ID where a.ACADEMIC_TERM='Fall' and r.ACADEMIC_TERM='Fall' and a.ACADEMIC_SESSION='' and a.ACADEMIC_YEAR = (Select Year(GetDate())) and r.ACADEMIC_YEAR = (Select Year(GetDate())) and (CLASS_LEVEL LIKE 'FR%' OR a.CLASS_LEVEL LIKE 'SO' OR a.CLASS_LEVEL LIKE 'JR' OR a.CLASS_LEVEL LIKE 'SR%') and r.RESIDENT_COMMUTER='R' For each person in the database it returns two rows with identical information. Yet, when I do the same query without the left join: select * from ACADEMIC a where a.ACADEMIC_TERM='Fall' and a.ACADEMIC_SESSION='' and a.ACADEMIC_YEAR = (Select Year(GetDate())) and (CLASS_LEVEL LIKE 'FR%' OR a.CLASS_LEVEL LIKE 'SO' OR a.CLASS_LEVEL LIKE 'JR' OR a.CLASS_LEVEL LIKE 'SR%') ORDER BY PEOPLE_ID It returns only one row for each person. I'm doing a left join - why is it adding an extra row? Shouldn't it only do that if I add a right join?

  Given these tables: create table Orders ( Id INT IDENTITY NOT NULL, primary key (Id) ) create table Items ( Id INT IDENTITY NOT NULL, primary key (Id) ) create table OrdersItems ( OrderId INT not null, ItemId INT not null, primary key (OrderId, ItemId) ) Is it possible to use HQL/criteria API to contruct a query that results in the following SQL: SELECT [OrderId], [ItemId] FROM [OrdersItems] I've tried both of these approaches: var hqlResults = session .CreateQuery("select order.id, item.id from Order order inner join order.Items item") .List(); var criteriaResults = session .CreateCriteria<Order>() .CreateAlias("Items", "item", NHibernate.SqlCommand.JoinType.None) .SetProjection(Projections.Property("id"), Projections.Property("item.id")) .List(); But both approaches insist on generating a join (or fail because the join isn't present, in using criteria), resulting in SQL such as: select order.Id, item.Id from Orders order inner join OrdersItems ordersItems on order.Id = ordersItems.ArticleId inner join Items item on ordersItems.CategoryId = item.Id Is there any way to have NHibernate generate a query that selects columns only from the join table, without requiring a join?
