  • Creating Tables and Retrieving Query results with Dynamics AX 2009 business connector

    - by namenlos
    I'm writing a C# command line tool to fetch data from AX and to add data (create new tables) to AX. Fetching data from an AX table is easy and documented here: http://msdn.microsoft.com/en-us/library/cc197126.aspx Adding data to an existing table is also easy: http://msdn.microsoft.com/en-us/library/aa868997.aspx But I cannot figure out how to do two things: Create a new AX Table Retrieve data from an AX Query Can someone please share some sample code or give some pointers on where to start looking. My searches on Google and MSDN have not revealed much. NOTE: I am not an experienced AX or ERP developer.

  • Multiple JOIN and SELECT Statements from eight tables

    - by user1486004
    I am trying to make an SQL statement that takes eight different numbers and searches eight different tables from one database for the corresponding value. I keep getting invalid syntax, but I can't figure out why. Here is my code: SELECT cable_length.ID, drawing.ID, optional.ID, output_type.ID, pressure_range.ID, pressure_type.ID, series.ID, termination.ID FROM ( SELECT value AS cable_length FROM A1 WHERE A1.id = %s JOIN SELECT value AS drawing FROM A2 WHERE A2.id = %s, JOIN SELECT value AS optional FROM A3 WHERE A3.id = %s, JOIN SELECT value AS output_type FROM A4 WHERE A4.id = %s, JOIN SELECT value AS pressure_range FROM A5 WHERE A5.id = %s, JOIN SELECT value AS pressure_type FROM A6 WHERE A6.id = %s, JOIN SELECT value AS series FROM A7 WHERE A7.id = %s, JOIN SELECT value AS termination FROM A8 WHERE A8.id = %s ); The %s will be changed to numbers only. The column name in each database is "ID" and "Value". I want to search by "ID" and return "Value". Any help is greatly appreciated.

  • Database theory - relationship between two tables

    - by iansinke
    I have a database with two tables - let's call them Foo and Bar. Each foo may be related to any number of bars, and each bar may be related to any number of foos. I want to be able to retrieve, with one query, the foos that are associated with a certain bar, and the bars that are associated with a certain foo. My question is, what is the best way of recording these relationships? Should I have a separate table with records of each relationship (e.g. two columns, foo and bar)? Should the foo table have a column for a list of bars, and vice versa? Is there another option that I'm overlooking? I'm using SQL Server, if that makes a difference.

  • FullText Search using multiple tables in SQL

    - by Caesar
    Hi there. I have 3 tables, tblBook(BookID, ISBN, Title, Summary) tblAuthor(AuthorID, FullName) tblBookAuthor(BookAuthorID, BookID, AuthorID) tblBookAuthor allows for a single book to have multiple authors and an author may have written any number of books. I am using full text search to search for ranking base on a word: SET @Word = 'FORMSOF(INFLECTIONAL, "' + @Word + '")' SELECT COALESCE(ISBNResults.[KEY], TitleResults.[KEY], SummaryResults.[KEY]) AS [KEY], ISNULL(ISBNResults.Rank, 0) * 3 + ISNULL(TitleResults.Rank, 0) * 2 + ISNULL(SummaryResults.Rank, 0) AS Rank FROM CONTAINSTABLE(tblBook, ISBN, @Word, LANGUAGE 'English') AS ISBNResults FULL OUTER JOIN CONTAINSTABLE(tblBook, Title, @Word, LANGUAGE 'English') AS TitleResults ON ISBNResults.[KEY] = TitleResults.[KEY] FULL OUTER JOIN CONTAINSTABLE(tblBook, Summary, @Word, LANGUAGE 'English') AS SummaryResults ON ISBNResults.[KEY] = SummaryResults.[KEY] The above code works fine for just searching tblBook table. But now I would like to search also the table tblAuthor based on key word searched. Can you help me with this?

  • Compile-time lookup array creation for ANSI-C?

    - by multiproximus
    A previous programmer preferred to generate large lookup tables (arrays of constants) to save runtime CPU cycles rather than calculating values on the fly. He did this by creating custom Visual C++ projects that were unique for each individual lookup table... which generate array files that are then #included into a completely separate ANSI-C micro-controller (Renesas) project. This approach is fine for his original calculation assumptions, but has become tedious when the input parameters need to be modified, requiring me to recompile all of the Visual C++ projects and re-import those files into the ANSI-C project. What I would like to do is port the Visual C++ source directly into the ANSI-C microcontroller project and let the compiler create the array tables. So, my question is: Can ANSI-C compilers compute and generate lookup arrays during compile time? And if so, how should I go about it? Thanks in advance for your help!

  • Display/Edit fields across tables in a Django Form

    - by jamida
    I have 2 tables/models, which for all practical purposes are the same as the standard Author/Book example, but with the additional restriction that in my application each Author can only write 0 or 1 books. (eg, the ForeignKey field in the Book model is or can be a OneToOneField, and there may be authors who have no corresponding book in the Book table.) I would like to be able to display a form showing multiple books and also show some fields from the corresponding Author table (eg author_name, author_address). I followed the example of the inlineformset and but that doesn't even display the author name in the generated form.

  • joining tables while keeping the Null values

    - by Tam
    I have two tables: Users: ID, first_name, last_name Networks: user_id, friend_id, status I want to select all values from the users table but I want to display the status of specific user (say with id=2) while keeping the other ones as NULL. For instance: If I have users: 1 John Smith 2 Tom Summers 3 Amy Wilson And in networks: user_id friend_id status 2 1 friends I want to do search for John Smith for all other users so I want to get: id first_name last_name status 2 Tom Summers friends 3 Amy Wilson NULL I tried doing LEFT JOIN and then WHERE statement but it didn't work because it excluded the rows that have relations with other users but not this user. I can do this using UNION statement but I was wondering if it's at all possible to do it without UNION.

  • MySQL "OR MATCH" hangs (long pause with no answer) on multiple tables

    - by Kerry
    After learning how to do MySQL Full-Text search, the recommended solution for multiple tables was OR MATCH and then do the other database call. You can see that in my query below. When I do this, it just gets stuck in a "busy" state, and I can't access the MySQL database. SELECT a.`product_id`, a.`name`, a.`slug`, a.`description`, b.`list_price`, b.`price`, c.`image`, c.`swatch`, e.`name` AS industry, MATCH( a.`name`, a.`sku`, a.`description` ) AGAINST ( '%s' IN BOOLEAN MODE ) AS relevance FROM `products` AS a LEFT JOIN `website_products` AS b ON (a.`product_id` = b.`product_id`) LEFT JOIN ( SELECT `product_id`, `image`, `swatch` FROM `product_images` WHERE `sequence` = 0) AS c ON (a.`product_id` = c.`product_id`) LEFT JOIN `brands` AS d ON (a.`brand_id` = d.`brand_id`) INNER JOIN `industries` AS e ON (a.`industry_id` = e.`industry_id`) WHERE b.`website_id` = %d AND b.`status` = %d AND b.`active` = %d AND MATCH( a.`name`, a.`sku`, a.`description` ) AGAINST ( '%s' IN BOOLEAN MODE ) OR MATCH ( d.`name` ) AGAINST ( '%s' IN BOOLEAN MODE ) GROUP BY a.`product_id` ORDER BY relevance DESC LIMIT 0, 9 Any help would be greatly appreciated.

    Hi guys, I have a very large database structure, (Data is not important at this point, I can migrate the info in the db pretty easily if the structure is done) , all reside in SQL Server and I even published it to SQL Azure, but thinking about the limitation of SQL Azure in size, made me decide to switch most of the tables that do not need all the bells and whistles of SQL Azure to Azure Table and blob storage. I was thinking of creating a TT template that dose that, but was wondering if their is a tool that do that. Any ideas or thoughts. The only tables that i would keep in SQL Azure would anything related to transactions like payments. Appreciate your thoughts and advice

  • C# dbml stops linking tables to code

    - by Philip
    I am having occasional trouble with my C# dbml where it starts not linking properly. I do not know how to replicate the exact cause of the problem, it was working perfectly until I changed a database table and then deleted the table and readded it with the new schema. The error message I get is "The type or namespace name 'tbl' could not be found (are you missing a using directive or an assembly reference?) The only fix I have found is to make a new dbml readd the tables. Any ideas what to do or why this is happening?

  • Are these tables respect the 3NF Database Normalization?

    - by penas
    AUTHOR table Author_ID, PK First_Name Last_Name TITLES table TITLE_ID, PK NAME Author_ID, FK DOMAIN table DOMAIN_ID, PK NAME TITLE_ID, FK READERS table READER_ID, PK First_Name Last_Name ADDRESS CITY_ID, FK PHONE CITY table CITY_ID, PK NAME BORROWING table BORROWING_ID,pk READER_ID, fk TITLE_ID, fk DATE HISTORY table READER_ID TITLE_ID DATE_OF_BORROWING DATE_OF_RETURNING Are these tables respect the 3NF Database Normalization? What if 2 authors work together for the same title? The column Addresss should have it's own table? When a reader borrows a book, I make an entry in BORROWING table. After he returns the book, I delete that entry and I make another one entry in HISTORY table. Is this a good idea? Do I brake any rule? Should I have instead one single BORROWING table with a DATE_OF_RETURNING column?

  • Python In-memory table

    - by nsharish
    What is the right way to forming in-memory table in python with direct lookups for rows and columns.I thought of using dict of dicts this way, class Table(dict): def __getitem__(self, key): if key not in self: self[key]={} return dict.__getitem__(self, key) table = Table() table['row1']['column1'] = 'value11' table['row1']['column2'] = 'value12' table['row2']['column1'] = 'value21' table['row2']['column2'] = 'value22' >>>table {'row1':{'column1':'value11','column2':'value12'},'row2':{'column1':'value21','column2':'value22'}} I had difficulty in looking up for values in columns. >>>'row1' in table True >>>'value11' in table['row1'].values() True Now how do I do lookup if 'column1' has 'value11' Is this method of forming tables wrong?Is there a better way to implement such tables with easier lookups?.Thanks

  • Subsonic custom mapping of objects to tables

    - by codekaizen
    Geeting, I'm using Compact Framework 3.5 and have tenatively settled on a custom build of Subsonic 3.0 to do data access. The trouble is that I am used to developing model-first but am also interested in keeping control of my DB schema. Therefore, neither ActiveRecord or Repository appears to meet my needs, and I want to use my existing POCO model and map it to my existing tables. I'm used to doing this via NHibernate and Entity Framework. After some investigation, it appears that I might be able to author a custom QueryMapping to give me the custom mapping I want. Before I start down this path, however, I'd like to see some kind of example of this being done. I can't seem to find any on the web, and wonder if anyone could give input on experience with Subsonic, model-first and a custom Table-per-Type and Table-per-Hierarchy mapping.

  • Django syncdb not making tables for my app

    - by Rosarch
    It used to work, and now it doesn't. python manage.py syncdb no longer makes tables for my app. From settings.py: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'mysite.myapp', 'django.contrib.admin', ) What could I be doing wrong? The break appeared to coincide with editing this model in models.py, but that could be total coincidence. I commented out the lines I changed, and it still doesn't work. class MyUser(models.Model): user = models.ForeignKey(User, unique=True) takingReqSets = models.ManyToManyField(RequirementSet, blank=True) takingTerms = models.ManyToManyField(Term, blank=True) takingCourses = models.ManyToManyField(Course, through=TakingCourse, blank=True) school = models.ForeignKey(School) # minCreditsPerTerm = models.IntegerField(blank=True) # maxCreditsPerTerm = models.IntegerField(blank=True) # optimalCreditsPerTerm = models.IntegerField(blank=True) UPDATE: When I run python manage.py loadddata initial_data, it gives an error: DeserializationError: Invalid model identifier: myapp.SomeModel Loading this data had worked fine before. This error is thrown on the very first data object in the data file.

  • Left Join 3 Tables and Show True or False on Empty Cells

    - by Jason Shultz
    Ok, this may be confusing so I hope I explain it correctly. I have 4 tables: business photos video category I want to display "featured" businesses on the home page (or elsewhere) and I want to show a Yes or No in the table row based upon whether or not there are photos or videos for that business. Example: Joes Crab Shack has no videos or photos but is featured. So, when his row is echoed out it will show the Business Name and Business Owner but there will be no data in the photo or video cells thus in the video and photos column it will say No. Otherwise, if the opposite was true, it would say Yes. Here's my pastebin

    http://stackoverflow.com/questions/1152405/postgresql-is-better-using-multiple-databases-with-1-schema-each-or-1-database I am new in schema concept for PostgreSQL. For the above mentioned scenario, I was wondering Why don't we use a single database (with default schema named public) Why don't we have a single table, to store multiple users row? Other tables which hold users related information, with foreign key point to the user table. Can anyone provide me a real case scenario, which single database, multiple schema will be extremely useful, and can't solve by conventional single database, single schema.

  • Select from multiple tables, remove duplicates

    - by staze
    I have two tables in a SQLite DB, and both have the following fields: idnumber, firstname, middlename, lastname, email, login One table has all of these populated, the other doesn't have the idnumber, or middle name populated. I'd LIKE to be able to do something like: select idnumber, firstname, middlename, lastname, email, login from users1,users2 group by login; But I get an "ambiguous" error. Doing something like: select idnumber, firstname, middlename, lastname, email, login from users1 union select idnumber, firstname, middlename, lastname, email, login from users2; LOOKS like it works, but I see duplicates. my understanding is that union shouldn't allow duplicates, but maybe they're not real duplicates since the second user table doesn't have all the fields populated (e.g. "20, bob, alan, smith, [email protected], bob" is not the same as "NULL, bob, NULL, smith, [email protected], bob"). Any ideas? What am I missing? All I want to do is dedupe based on "login". Thanks!

  • VB.net 'cross-referencing' tables.

    - by Lee
    Hello, I have a DataGridView that is being filled with data from a table. Inside this table is a column called 'group' that has the ID of an individual group in another table. What I would like to do, is when the DataGridView is filled, instead of showing the ID contained in 'group', I'd like it to display the name of the group. Is there some type of VB.net 'magic' that can do this, or do I need to cross-reference the data myself? Here is a breakdown of what the 2 tables look like: table1 id group (this holds the value of column id in table 2) weight last_update table2 id description (this is what I would like to be displayed in the DGV.) take care, lee BTW - I am using Visual Studios Express.

  • How can you name the Dataset's Tables you return in a stored proc ?

    - by Brann
    I've got the following stored procedure Create procedure psfoo () AS select * from tbA select * from tbB I'm then accessing the data this way : Sql Command mySqlCommand = new SqlCommand("psfoo" , DbConnection) DataSet ds = new DataSet(); mySqlCommand.CommandType = CommandType.StoredProcedure; SqlDataAdapter mySqlDataAdapter = new SqlDataAdapter(); mySqlDataAdapter.SelectCommand = mySqlCommand; mySqlDataAdapter.Fill(ds); Now, when I want to access my tables, I have to do this : DataTable datatableA = ds.Tables[0]; DataTable datatableB = ds.Tables[1]; the dataset Tables property also got an accessor by string (instead of int). Is it possible so specify the name of the tables in the SQL code, so that I can instead write this : DataTable datatableA = ds.Tables["NametbA"]; DataTable datatableB = ds.Tables["NametbB"]; I'm using SQL server 2008, if that makes a difference.

  • SQL joins "going up" two tables

    - by blcArmadillo
    I'm trying to create a moderately complex query with joins: SELECT `history`.`id`, `parts`.`type_id`, `serialized_parts`.`serial`, `history_actions`.`action`, `history`.`date_added` FROM `history_actions`, `history` LEFT OUTER JOIN `parts` ON `parts`.`id` = `history`.`part_id` LEFT OUTER JOIN `serialized_parts` ON `serialized_parts`.`parts_id` = `history`.`part_id` WHERE `history_actions`.`id` = `history`.`action_id` AND `history`.`unit_id` = '1' ORDER BY `history`.`id` DESC I'd like to replace `parts`.`type_id` in the SELECT statement with `part_list`.`name` where the relationship I need to enforce between the two tables is `part_list`.`id` = `parts`.`type_id`. Also I have to use joins because in some cases `history`.`part_id` may be NULL which obviously isn't a valid part id. How would I modify the query to do this?
