• SqlAlchemy hangs after adding record in MS SQL

  - by Patrick

  I'm running SQLAlchemy on Jython and trying to connect to a MS SQL database using jTDS with windows authentication. I can query and delete just fine but when I try to insert new values it will hang when I commit. int 'before add' session.add(newVal) print 'after add' session.commit() print 'after commit' I see the first two print statements but not the last. My CPU maxes out and I can't even query the table directly using the MS SQL Management Studio. When I kill the Jython java process I can query again but the new values haven't been added. Strangely enough I can insert values directly using an SQL command: insert_sql = "INSERT INTO my_table (my_value) VALUES ('test_value')" session.execute(insert_sql) session.commit() Any ideas what I'm doing wrong?

• Can JPA do batch update | put | write | insert as pm.makePersistentAll() does in GAE/J

  - by Kenyth

  I searched through multiple discussions here. Can someone just give me a quick and direct answer? And if with JPA you can't do a batch update, what if I don't use transaction, and just use the following flow: em = emf.getEntityManager // do some query // make some data modification em.persist(..) // do some query // make some data modification em.persist(..) // do some query // make some data modification em.persist(..) ... em.close() How does this compare to batch update with regard to performance, and compare to a single transaction commit, measured by RPC calls to datastore server, CPU cycles per request, or so. Does every call to em.persist(..) before em.close() trigger a RPC call to the datastore server? Thanks very much for any response!

• C# mysql one return last_insert_id

  - by Bernhard

  I am trying to create a method in which I can exequte mysql UPDATE, DELETE or INSERT query. The method must work when with an INSERT I ask or do not ask the last_insert_id(). Below is the code that I have at the moment: public int executeUID(MySqlCommand msCommand) { try { this.Open(); msCommand.Connection = this.msCon; return int.Parse(msCommand.ExecuteScalar().ToString()); } catch (MySqlException ex) { throw ex; } finally { this.Close(); } } The problem with this is is that when I use an insert query that returns a last_insert_id() the method works greatly. But when the query doesn't return an last_insert_id() the method malfunctions. How can I get this method to work?

• Strange type in c++

  - by Cemre

  I have a method with the prototype: bool getAssignment(const Query& query, Assignment *&result); I am a bit confused about the type of the second param (Assignment *&result) since I don't think I have seen something like that before. It is used like: Assignment *a; if (!getAssignment(query, a)) return false; Is it a reference to a pointer or the other way around ? or neither ? Any explanation is appreciated. Thanks.

• Get the sum by comparing between two tables

  - by Ismail Gunes

  I have to tables ProdBiscuit As tb and StockData As sd , I have to get the sum of the quantity in StockData (quantite) with the condition of if (sd.status0 AND sd.prodid = tb.id AND sd.matcuisine = 3) Here is my sql query SELECT tb.id, tb.nom, tb.proddate, tb.qty, tb.stockrecno FROM ProdBiscuit AS tb JOIN (SELECT id, prodid, matcuisine, status, SUM(quantite) AS rq FROM StockData) AS sd ON (tb.id = sd.prodid AND sd.status > 0 AND sd.matcuisine = 3) LIMIT 25 OFFSET @Myid This gives me no rows at all ? There is only 3 rows in ProdBiscuit and 11 rows in Stockdata and there is only 2 rows in StockData good with the condition. And as shown in the picture there is only two rows which give the condition. What is wrong in my query ? PS: The green lines on the image shows the condition in my query.

• Multiple LIKE, OR MySql Queries Match

  - by Codex73

  Search for: 'chemist' Problem: query which will match a string like 'onechemist' but not 'chemist'. SELECT id,name FROM `records` WHERE name LIKE '%". mysql_real_escape_string($q) ."%' This alternate try won't work: SELECT id,name FROM `records` WHERE name LIKE '%". mysql_real_escape_string($q) ."%' OR name LIKE '". mysql_real_escape_string($q) ."%' OR name LIKE '%". mysql_real_escape_string($q) ."' How could I compile the above into one single query that will match any field which has the string or optimize the query into a better expression?

• Problem using Min(field)

  - by Todd

  have these two queries: SELECT classroomid AS crid, startdate AS msd FROM unitTemplates where classroomid = 6 GROUP BY classroomid and: SELECT classroomid AS crid, Min(startdate) AS msd FROM unitTemplates where classroomid = 6 GROUP BY classroomid The second query uses the minimum function. There is only one record in my table with a classroomid of 6. The first query returns msd = 20100505, the second query returns msd = 0 (instead of the expected 20100505). If I change the "Min" to "Max" it returns the highest (and only) startdate (20100505). Why doesn't MySQL like the Min function I'm using?

• Using SQLAlchemy, how can I return a count with multiple columns

  - by Andy

  I am attempting to run a query like this: SELECT comment_type_id, name, count(comment_type_id) FROM comments, commenttypes WHERE comment_type_id=commenttypes.id GROUP BY comment_type_id Without the join between comments and commenttypes for the name column, I can do this using: session.query(Comment.comment_type_id,func.count(Comment.comment_type_id)).group_by(Comment.comment_type_id).all() However, if I try to do something like this, I get incorrect results: session.query(Comment.comment_type_id, Comment.comment_type, func.count(Comment.comment_type_id)).group_by(Comment.comment_type_id).all() I have two problems with the results: (1, False, 82920) (2, False, 588) (3, False, 4278) (4, False, 104370) Problems: The False is not correct The counts are wrong My expected results are: (1, 'Comment Type 1', 13820) (2, 'Comment Type 2', 98) (3, 'Comment Type 2', 713) (4, 'Comment Type 2', 17395) How can I adjust my command to pull the correct name value and the correct count?

• SQL alert for a stored procedure?

  - by superdupersomething

  I have a SQL 2005 setup and am rather new :) Been cracking at this for a few hours and I just need some help. I have been able to setup alerts successfully for the standard "SQL server performance events", its fun. So I already have email alerts working. However I need the alert thing to run a stored procedure I have created, and depending on its output it will alert me or not via email. So far I have been trying to use the WMI events, but I keep getting an error "The @wmi_query could not be executed in the @wmi_namespace provided. Verify that an event class selected in the query exists in the namespace and that the query has the correct syntax" the query definitely works so I have no idea.. is there a different way to do this?

• MYSQL sum() for distinct rows

  - by makeee

  I'm looking for help using sum() in my SQL query (not posting full query since the scenario is fairly simple). I have COUNT(DISTINCT conversions.id) in my query. I use DISTINCT because I'm doing "group by" for multiple columns and this ensures the same row is not counted more than once. Now I want to add: SUM(conversions.value) as conversion_value The problem is that the "value" for each row is counted more than once (due to the multiple group bys) I basically want to do SUM(conversions.value) for each DISTINCT conversions.id. Is that possible?

• [sqlalchemy] subquery in select statement

  Hi guys, I have two tables (albums,pictures) in a one to many relationship and I want to display each albums details with one picture so I have the following query select albums.name,(select pictures.path from pictures where pictures.albumid=albums.id limit 1) as picture from albums where ... Now I'm struggling creating this on Pylons with sqlalchemy I tried to do the following picture = Session.query(model.Picture) sub_q = picture.filter_by(albumid = model.Album.id).limit(1).subquery() album_q = Session.query(model.Album, sub_q) result = album_q.all() but it creates the following statement displaying the incorrect picture beacuse the table albums is included in the subquery select albums.name,(select pictures.path from pictures,albums where pictures.albumid=albums.id) from albums where ... Am I doing it wrong?, is this even possible in sqlalchemy?.

• Django: optimizing queries

  - by Josh

  I want to list the number of items for each list. How can I find this number in a single query, rather than a query for each list? Here is a simplified version of my current template code: {% for list in lists %} <li> {{ listname }}: {% with list.num_items as item_count %} {{ item_count }} item{{ item_count|pluralize }} {% endwith %} </li> {% endfor %} lists is passed as: List.objects.filter(user=user) and num_items is a property of the List model: def _get_num_items(self): return self.item_set.filter(archived=False).count() num_items = property(_get_num_items) This queries SELECT COUNT(*) FROM "my_app_item" WHERE... n times, where n is the number of lists. Is it possible to make a single query here?

• Selecting a sequence NEXTVAL for multiple rows

  - by stringpoet

  I am building a SQL Server job to pull data from SQL Server into an Oracle database through a linked server. The table I need to populate has a sequence for the name ID, which is my primary key. I'm having trouble figuring out a way to do this simply, without some lengthy code. Here's what I have so far for the SELECT portion (some actual names obfuscated): SELECT (SELECT NEXTVAL FROM OPENQUERY(MYSERVER, 'SELECT ORCL.NAME_SEQNO.NEXTVAL FROM DUAL')), psn.BirthDate, psn.FirstName, psn.MiddleName, psn.LastName, c.REGION_CODE FROM Person psn LEFT JOIN MYSERVER..ORCL.COUNTRY c ON c.COUNTRY_CODE = psn.Country MYSERVER is the linked Oracle server, ORCL is obviously the schema. Person is a local table on the SQL Server database where the query is being executed. When I run this query, I get the same exact value for all records for the NEXTVAL. What I need is for it to generate a new value for each returned record. I found this similar question, with its answers, but am unsure how to apply it to my case (if even possible): Query several NEXTVAL from sequence in one satement

• Duplicate records

  - by czuroski

  Hello, I am using nHibernate for db persistence. I have a one-to-many relationship defined between 2 tables. When I query and try to get data, I am getting the correct number of rows from the "many" table, but the rows are duplicates of the first row returned. table1 (one), table2 (many). I create a criteria query to get a certain record from table1. I then expect to get all associated records from table2. ie, table1 holds orders, table2 holds items. I query table1 to get an order which has 4 items. I expect to see each of those 4 items from table2, but all I am seeing is the 1st item repeated 4 times. Does anyone have any idea what might be happening?

• Why my mysql DISTINCT doesn't work ?

  - by belaz

  Hello, Why the two query below return duplicate member_id and not the third ? i need the second query to work with distinct.

• SqlDataAdapter.Fill suddenly taking a long time

  - by WraithNath

  I have an application with a central DataTier that can execute a query to a data table using an SQLDataAdapter. None of this code has changed but now all queries are taking at least 10x as long to execute a query returning even one record. The only difference is that I have been using the app in a VM but the issue has started mid way through using the application. eg, the speed issue has not manifested itself from the start of using the VM, rather half way through. Has anyone else had an issue with the SQL Data Adapter taking a long time to fill for no reason? executing the query in Management studio it runs in less than a second. Firewalls are disabled

• Querying a smalldatetime's date and time seperately in SQL server?

  - by Kylee

  Imagine a table that has two fields, a smalltimedate and an int and about 1000 rows of data. What I'm attempting to do in query is to find the average of the INT field for rows between 3/3/2010 - 3/13/2010 and only if the entry is between 6:00am - 11:00pm. I tried between '2010-03-03 06:00 AND 2010-03-13 23:00' However that only restricts that very beginning and end times. I could do this with a loop but I'm going to need to have the same query run over much larger date ranges and this will quickly eat server resources. Is there a way to query date and time seperately?

• Symfony use NativeSQL to JOIN unrelated tables

  I'd like to run a query like this: $rsm = new ResultSetMappingBuilder($this->em); $rsm->addRootEntityFromClassMetadata('myBundle:Foo', 'f'); $rsm->addRootEntityFromClassMetadata('myBundle:Bar', 'b'); $sql = 'SELECT l.*, b.* FROM foos f INNER JOIN FROM bars b ON b.baz_id = f.baz_id WHERE l.bam = 1'; $query = $this->em->createNativeQuery($sql, $rsm); $fooBarQuery= $query->getResult(); Unfortunately this is not a situation where I can set up a proper relationship in the entity. Is not going to be possible for me to do this? Thanks.

• Combining IN and NOT IN in SQL as single result

  - by UltraVi01

  I apologize for the vague title. I am attempting to write a query that returns an alias column with matching values (resulting from an IN) as well as an alias column with values that do not match (using NOT IN). I want the result set to have: userId | matches | nonmatches. I currently have the following query which returns the matches as expected. I am having trouble getting the nonmatches in the result set -- that is, from a NOT IN statement SET @userId = 9; SELECT ug.user_id, COUNT(DISTINCT goal_id) as matches FROM user_goal ug WHERE ug.user_id!=@userId AND goal_id IN (SELECT iug.goal_id FROM user_goal iug WHERE user_id=@userId) GROUP BY user_id ORDER BY matches DESC LIMIT 4 So, the NOT IN would look something like this: goal_id NOT IN(SELECT uggg.goal_id FROM user_goal uggg WHERE user_id=@userId) AS nonmatches I am just not sure how to incorporate the NOT IN statement in my query so I get all the results

• iqueryable select/where not working

  - by Steve

  I have two tables Boxer and Prospect. Boxers has general stuff like name and and dob etc and a BoxerId While Prospect contains only one value (at the moment) which is a boxerId. If a boxer is a prospect(up and coming boxer) there Id will be in the prospect table. This works fine but now I want to select all boxers that are prospects public static IQueryable<Boxer> IsProspect(this IQueryable<Boxer> query) { //this does not filter down to only prospects!!! return query.Where(x => x.Prospect != null); } This is the function I call using: var repository = GetRepository<Boxer>(); var boxers = repository.Query().IsProspect(); I would hope this would filter my collection of all boxers down to just boxers that are prospects! Oddly it doesnt filter it but if i hover over my boxers object and look at each boxer during debugging I can see "IsProspect" true or false correctly

• Both sql LAST_INSERT_ID() and PHP insert_id return 0

  - by jakubplus

  I've been searching google a lot for this issue and really found nothing. People just keep copying MySQL documentation on last_insert_id and nothing else. I've got an issue regarding last_insert_id, because for both situations (php & sql) it returns 0. YES: I've set a PRIMARY & UNIQUE field with AUTO_INCREMENT value YES: i've done some inserting before NO: Making double query with INSERT AND SELECT LAST... doesn't work. I've created a class Db for maintaining connection & query: class Db { public function connect() { $db = new mysqli('','','','',''); ... return $db; } public function insert() { $this->connect()->query("INSERT INTO bla bla..."); return $this->connect()->insert_id; } } And it doesn't work.
