  • CONTAINSTABLE with wildcard works different in SQLServer 2005 and SQLServer 2008?

    - by musuk
    I have two same databases one on SQLServer 2005 and one on SqlServer 2008, it have same SQL_Latin1_General_CP1_CI_AS Collation, and full text search catalogs have the same settings. These two databases contains table with same data, NTEXT string: "...kræve en forklaring fra miljøminister Connie Hedegaard.." My problem is: CONTAINSTABLE on SQLServer 2008 finds nothing if query is: select * from ContainsTable(SearchIndex_7, Content, '"miljø*"') ct but SQLServer 2005 works perfectly and finds necessary record. SQLServer 2008 finds necessary record if query is: select * from ContainsTable(SearchIndex_7, Content, '"milj*"') ct or select * from ContainsTable(SearchIndex_7, Content, '"miljøminister"') What can be reason for so strange behavior?

  • nth smallest number among two databases of size n each using divide and conquer

    - by urfriend
    we have two databases of size n containing numbers without repeats. So, in total we have 2n elements. They can be accessed through a query to one database at a time. The query is such that you give it a k and it returns kth smallest entry in that database. we need to find nth smallest entry among all the 2n elements in O(logn) queries. the idea is to use divide and conquer but i need some help thinking through this. thanks!

  • Pear MDB2 class and raiserror exceptions in SQL Server

    - by drholzmichl
    Hi, in SQL Server it's possible to raise an error with raiserror(). I want to use a severity, which doesn't interrupt the connection. This error is raised in a stored procedure. In SQL Management Studio all is fine and I get my error code when executing this SP. But when trying to execute this SP via MDB2 in PHP5 this doesn't work. All I get is an empty array. MDB2 object is created via (including needed options): $db =& MDB2::connect($dsn); $db->setFetchMode(MDB2_FETCHMODE_ASSOC); $db->setOption('portability',MDB2_PORTABILITY_ALL ^ MDB2_PORTABILITY_EMPTY_TO_NULL); The following works (I get a PEAR error): $db->query("RAISERROR('test',11,0);"); But when calling a stored procedure which raises this error via $db->query("EXEC sp_raise_error"); there is not output. What's wrong?

  • Deleting rows with MySQL LEFT JOIN

    - by fabrik
    Hello! I have two tables, one for job deadlines, one for describe a job. Each job can take a status and some statuses means the jobs' deadlines must be deleted from the other table. I can easily SELECT the jobs/deadlines that meets my criteria with a LEFT JOIN: SELECT * FROM `deadline` LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` = 'szamlazva' OR `status` = 'szamlazhato' OR `status` = 'fizetve' OR `status` = 'szallitva' OR `status` = 'storno' (status belongs to job table not deadline) But when i'd like to delete these rows from deadline, MySQL throws an error. My query is: DELETE FROM `deadline` LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` = 'szamlazva' OR `status` = 'szamlazhato' OR `status` = 'fizetve' OR `status` = 'szallitva' OR `status` = 'storno' MySQL error says nothing: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` = 'szaml' at line 1 How can i turn my SELECT into a working DELETE query? Thanks, fabrik

  • MySQL JDBC date issues with database server in different timezone

    - by Somatik
    I have a database server in "Europe/London" time zone and my web server in "Europe/Brussels". Since it is summer time now my application server has a 2 hour difference. I created a test to reproduce my issue: Query q = JPA.em().createNativeQuery("SELECT UNIX_TIMESTAMP(startDateTime) FROM `Event` WHERE `id` =574"); BigInteger unix = (BigInteger) q.getSingleResult(); System.out.println(unix + "000 UNIX_TIMESTAMP to BigInteger"); Query q2 = JPA.em().createNativeQuery("SELECT startDateTime FROM `Event` WHERE `id` =574"); Timestamp o = (Timestamp) q2.getSingleResult(); System.out.println(o.getTime() + " Timestamp"); The startDateTime column is defined as 'datetime' (but same issue with 'timestamp') The output I am getting is this: 1340291591000 UNIX_TIMESTAMP to BigInteger 1340284391000 Timestamp Reading java date objects results in a shift in time zone, how do I fix this? I would expect the jdbc driver to just set the "unix time" value it gets from the server in the Date object. (a proper solution should work with any timezone combination, not only for db in GMT)

  • CakePHP: How do I order results based on a 2-level deep association model?

    - by KcYxA
    I'm hoping I won't need to resort to custom queries. A related question would be: how do I retrieve data so that if an associated model is empty, no record is retrieved at all, as opposed to an empty array for an associated model? As an oversimplified example, say I have the following models: City -- Street -- House How do I sort City results by House numbers? How do I retrieve City restuls that have at least one House in it? I don't want a record with a city name and details and an empty House array as it messes up pagination results. CakePHP retrieves House records belonging to the Street in a separate query, so putting somthing like 'House.number DESC' into the 'order' field of the search query returns a 'field does not exist' error. Any ideas?

  • Rails relation select

    - by Dimitar Vouldjeff
    Hi, I have the following models: class User < ActiveRecord::Base has_many :results, :dependent => :destroy has_many :participants, :dependent => :destroy has_many :courses, :through => :participants end class Course < ActiveRecord::Base has_many :tests, :dependent => :destroy has_many :participants, :dependent => :destroy has_many :users, :through => :participants end class Result < ActiveRecord::Base belongs_to :test belongs_to :user end class Test < ActiveRecord::Base belongs_to :course has_many :results, :dependent => :destroy end The Idea is that a user has_and_belongs_to_many courses, the course has_many tests, and every test has_and_belongs_to_many users (results). So what is the best query to select every Result from a single Course (not test), and also the query to select every Result from a single Course, but from one user. Thanks!

  • Hibernate: same generated value in two properties

    - by Markos Fragkakis
    Hi, I have an entity A with fields: aId (the system id) bId I want the first to be generated: @Id @Column(name = "PRODUCT_ID", unique = true, nullable = false, precision = 12, scale = 0) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "PROD_GEN") @BusinessKey public Long getAId() { return this.aId; } I want the bId to be initially exactly as the aId. One approach is to insert the entity, then get the aId generated by the DB (2nd query) and then update the entity, setting the bId to be equal to aId (3rd query). Is there a way to get the bId to get the same generated value as aId? Note that afterwards, I want to be able to update bId from my gui. If the solution is JPA, even better.

  • Get the AVG of two SQL Access Queries

    - by reggiereg
    Hi, I'm trying to get the AVERAGE from the results of two separate sql queries built in MS Access. The first sql query pulls the largest record: SELECT DISTINCTROW Sheet1.Tx_Date, Sheet1.LName, Sheet1.Patient_Name, Sheet1.MRN, Max(Sheet1.) AS [Max Of FEV1_ACT], Max(Sheet1.FEF_25_75_ACT) AS [Max Of FEF_25_75_ACT] FROM Sheet1 GROUP BY Sheet1.Tx_Date, Sheet1.LName, Sheet1.Patient_Name, Sheet1.MRN; The second sql query pulls the second largest record: SELECT Sheet1.MRN, Sheet1.Patient_Name, Sheet1.Lname, Max(Sheet1.FEV1_ACT) AS 2ndLrgOfFEV1_ACT, Max(Sheet1.FEF_25_75_ACT) AS 2ndLrgOfFEF_25_75_ACT FROM Sheet1 WHERE (((Sheet1.FEV1_ACT)<(SELECT MAX( FEV1_ACT ) FROM Sheet1 ))) GROUP BY Sheet1.MRN, Sheet1.Patient_Name, Sheet1.Lname; These two queries work great, I just need some help on pulling the AVERAGE of the results of these two queries into one. Thanks.

  • Cursor (touchpad) moves and clicks erratically

    - by James Wood
    Sometimes (usually after two-finger scrolling) the touchpad on my Asus X54C becomes unresponsive and the cursor begins to click and move small distances. Clicking seems to happen more often than moving. Unlike with other similar problems, I've never seen the cursor move to (0, 0). Suspending (closing the lid) and unsuspending doesn't help, and neither does moving to a tty and back or rebooting. I've also tried disabling the touchpad via Fn+F9. That tends to take a long time, but doesn't have any effect. I'm on 13.10 at the moment, but I remember it happening on 13.04 as well. Here's the pointer section of xinput: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? ETPS/2 Elantech Touchpad id=12 [slave pointer (2)]

  • does mysql stored procedures support data types like array, hash,etc?

    - by Yang
    i am creating a mysql function which takes in a varchar and change it to a int based on a mapping table. select name, convert_to_code(country) from users where sex = 'male' here, the convert_to_code() function takes in a country name (e.g. Japan, Finland..) and change it to country code which is an integer (e.g. 1001, 2310..) based on a mapping table called country_maping like below: country_name (varchar) | country_code (int) Japan | 1001 Finland | 2310 Canada | 8756 currently, the stored function need to select country_code from country_mapping where country_name = country_name and return the query result. is that possible to create a hash data struct in SP to optimize the process so that it will not need to perform the query for each row matches the where clause. thanks in advance!

  • Avoiding Nested Queries

    - by Midhat
    How Important is it to avoid nested queries. I have always learnt to avoid them like a plague. But they are the most natural thing to me. When I am designing a query, the first thing I write is a nested query. Then I convert it to joins, which sometimes takes a lot of time to get right. And rarely gives a big performance improvement (sometimes it does) So are they really so bad. Is there a way to use nested queries without temp tables and filesort

Why? How can I get all children's trees?

  • Studying parallel programming

    - by mort
    I'm currently finishing my Bachelor's degree in Computer Science and thinking a lot about which specialisation to choose in my Master's degree. One subject I'm particularly interested in is parallel programming. However, this topic does not seem to be a standard topic in Computer Science degrees, although it is something that is used more and more - new processors nowadays are usually dual or quad cores. So I was wandering: does anybody know a good study program in this field? I was mostly looking for it at universities in Germany, but they tend to combine the application side with some type of engineering or natural science. Thus, programs are more the "Computational Engineering" or "Computational Science" type, but I'm more interested in the Computer Science part of it, i.e. parallel programming, languages and compilers, algorithms and hardware.

  • Mysql Select 1:n

    - by clinisbut
    Hello, I have two tables that relates 1:n content --------- - id - title - text content_meta ------------- - id - content_id - meta_key - meta_value A content can have multiple content_meta registers associated to it. Typically content_meta will contain the category, tags, descriptions and all that stuff, so I really don't know the number of registers a content will have. What I want to accomplish is to take the content register and also all the related registers in content_meta in a single query. I've tried the subselect approachment but seems that I can only get one register/column (¿?) SELECT content.*, ( SELECT * FROM content_meta WHERE content_id = content.id ) FROM content This query complains that "Operand should contain 1 column(s)", so changing the '*' by for example meta_key clears the error, but returns a NULL for this subselect... SELECT content.*, ( SELECT meta_key FROM content_meta WHERE content_id = content.id ) FROM content Can anybody show me where to go from here please?

I can do it using mysql> insert into gifts (name, filename, effectiveTime) -> values ("coffee", "coffee123.jpg", now()); Query OK, 1 row affected (0.00 sec) but the column names need to be all specified. Is there a way that they don't have to be specified and the auto increment of primary key still works? thanks.

  • Expand in linq not loading inner data collections from service.

    - by Kit
    I am seeing odd behavior with service queries! I am using MVVM pattern for a silverlight 3 app on 3.5 framework and Dataservices 1.5. The following code eager loads correctly the parent object and the child heirarchy perfectly IF and ONLY IF I am preloading the data. But I would like to fetch a different set of the parent object (and its child heirarchy) on different button clicks. What I am seeing is that on button click, only the parent object is retrieved, and the child heirarchy contains nothing. Any suggestions? Any ideas how to tackle this? Thanks all. The method: DataServiceQuery serviceQuery = (DataServiceQuery)(from m1 in dbEntities.gis_Region.Expand("gis_RegionValue/gis_Measure") where m1.RegionGuid == new Guid(regionGuid) select m1); serviceQuery.BeginExecute(GetRegionDetailAsyncResult, serviceQuery); The wired Async Result: DataServiceQuery query = (DataServiceQuery)result.AsyncState; gis_Region region = query.EndExecute(result).First();
