  • How to specify blob type in MS Access?

    - by Firat
    How to specify blob type in MS Access? I have office 2007 installed. I am using jdbc, but this should not matter for the SQL query I am passing. Tried to pass a length to it, or FILE type, did not help. CREATE TABLE mytable ( [integer] INTEGER not null, [string] VARCHAR (255), [datetime] DATETIME, [boolean] BIT, [char] CHAR, [short] SHORT, [double] DOUBLE, [float] FLOAT, [long] LONG, [blob] BLOB, // does not work Primary Key ([integer]) )

  • Quering computed fields in GORM

    - by Tihom
    I am trying to query the following HQL using GORM: MailMessage.executeQuery("toId, count(toId) from (SELECT toId, threadId FROM MailMessage as m WHERE receiveStatus = '$u' GROUP BY threadId, toId) as x group by x.toId") The problem is that count(toId) is a computed field doesn't exist in MailMessage and that I am using a subquery. I get the following error: java.lang.IllegalArgumentException: node to traverse cannot be null! Ideally, I would like to use a generic executeQuery which will return data of anytype. Is there such a thing?

  • Is there a way to get photo tags and new friendship type events by querying the FQL stream table?

    - by Fletcher Moore
    When you look at your stream on the Facebook website, events such as "FriendX was tagged in an album", "FriendY is attending EventZ", and "FriendK and FriendL are now friends". I've tried various "vague" queries on the stream table, and so far I have been unable to get these types of events. Is this possible, or do I need to query the all of the other tables and write a ton of logic to try to figure out which new events to show and how to show them?

  • Python what's the data structure for triple data

    - by Paul
    I've got a set of data that has three attributes, say A, B, and C, where A is kind of the index (i.e., A is used to look up the other two attributes.) What would be the best data structure for such data? I used two dictionaries, with A as the index of each. However, there's key errors when the query to the data doesn't match any instance of A.

    - by vfilby
    I am learning rails and am toying with a simple web-app that integrates with flickr to search photos based on user given criteria and store the query in a search history table. I am seeking the best or 'rails' way of handling this.

  • SubSonic 3 LeftOuterJoin

    - by michaelpearce
    I have read in this forum that left outer join syntax is not supported by subsonic in an answer to a question on the topic by "Apocatastasis". I have the same issue in that when I create a query using the .LeftOuterJoin the resulting sql has an inner join rather than a left outer join. Can someone please confirm that LeftOuterJoin is indeed not supported and, if that is the case, why is it included in the active record syntax? Thanks Michael

  • Determine Last Modification Datetime for an Azure Table

    - by embeddedprogrammer
    I am developing an application which may be hosted on a microsoft sql server, or on Azure SQL, depending upon the end user's wishes. My whole system works fine with the exception of some WCF functions which determine the last modification time of tables using the following technique: SELECT OBJECT_NAME(OBJECT_ID) as tableName, last_user_update as lastUpdate FROM mydb.sys.dm_db_index_usage_stats This query fails in Azure. Is there any analogous way to get table last modification dates from Azure's sql?

  • Can I cache a ManyToOne hibernate object without it being lazy loaded?

    - by Andrew
    @ManyToOne @JoinColumn(name = "play_template_id", table = "team_play_mapping" ) public Play getPlay() { return play; } public void setPlay( Play play ) { this.play = play; } By default, this is eager loading. Can I get it so that it will read the play object from a cache without making it lazy loading? Am I correct that eager loading will force it to do a join query and hence no caching?

  • Is there any library to represent SQL queries as objects in Java code?

    - by Pregzt
    I was wondering if there is any library that can be used to represent SQL queries as objects in Java. In the code I have plenty of static variables of type java.lang.String that are hand written SQL queries. I would be looking for library having a nice fluent API that allows me to represent the queries as objects rather than strings. Example: Query q = select("DATE", "QUOTE") .from("STOCKMARKET") .where(eq("CORP", "?")) .orderBy("DATE", DESC);
