  If it is only the data (not apps) I use Dropbox. It turned out to be the best way to move things between the side Mac and the bootcamped Windows of my iMac side. I don't see why it would not work to move data from a virtual machine installation of Win to a BootCamp installation.

• Export of data from text to MicroSoft Acess via SQLExec

  I was able to export numberical data in a Microsoft Access (mdb) database.  However, I have problems of export of text from a datamember data.  I use the SQLExec object to achieve this.

  Here is the general syntax of SQLExec I put in place for the text values:

  "INSERT INTO test (column1) VALUES('"&(text(\\.\Process1\TEXTENTRY.value,"0")& "')

  The value of the datamember TEXTENTRY will matter in the mdb file, column1 if it is digital.  Not if it is alpha-numeric.  The column is implemented for the text format.

  However, I am unable to import 'fixed' characters (not datamember text) to the database that is to say:

  "INSERT INTO test VALUES ('hello') (column1) the result is Hello will be in Column1.

  Please notify.

  Thank you!

  The text() function converts the digital text, so you do not need.

  Try the VALUE ('"' & TEXTENTRY &" ' ")

  Hello
  I'm new to soa, I want to create an xml with the data from database tables, I'll have the xsd please suggest me how to get the data in the tables and insert in a file
  concerning

  in your bpel process, you can use the db adapter to communicate with the database.
  with this type of adapter, you can use stored procedures, selects, etc to get the data from your database into your bpel workflow.

  When did it call in your bpel to the db adapter process it will return an output_variable with the contents of your table data, represented in a style of xml form.

  After that, you can use the second card (a file synchronization adapter) to write to the content of this variable in output to the file system

  The issue is that I can't understand that I should create the view by the union of the haggis and the two gus data or only haggis.
  the reason I believe I need to combine the two is mentioned * "" create views in your database schema HAGGIS who join their all the qualities of the review. ". *
  By the mention of creating views and who join their all the qualities of the review, it probably means to obtain the data of the GUS and HAGGIS.

  This is my interpretation of the assignment, too.
  If you ask just the tables on Gus, you will get the ranks of three of the four schools: it's not all examination classes.
  If you ask just the tables on Haggis, you will get the ranks of any of the four schools: it's not all examination classes.

  2nd prob is that if have decided to create a view that gets the data from these two gus and therer haggis would be a lot of duplication involved due to the cross product

  Why would there be "repetition involved due to the cross-product"?
  If the quuery of Gus produces 100 lines, the request of product Haggis 30 rows, then the UNION of the two will have 100 + 30 = 130 lines (assuming, as you say, each student is at school only one).

  You should not write, not to mention not formatted zip code. I have a little time I can devote to answering questions in the forum. Do you want me
  b spend this time formatting your code, so I can understand the question, and no time to answer, or
  b spend only a little time reading understanding your code and spend most of my time to help you?
  I would prefer (b), but the choice is yours.
  See the statement that I posted in my last post for an example of the formatted code. You see how it appears in a box with a police fixed-width, and multiple spaces are printed? This is because I typed {code} (all small letters), before and after the section I wanted formatted.

  At least put each table in the FROM clause on a separate line, so it is easy to know if you have enough join conditions.
  If you have N tables in the FROM clause, you almost always have at least N-1 join conditions that specify how the tables are linked together. For example, if talk you about two tables, quality and student, you expect to see a join condition that tells you when you have data in a table, how to find related data in the other table, such as

  g_gus.upn = s_gus.upn
  

  No no no join conditions will cause "repetition involved due to the cross product.

• Using the calendar function to select and read data from MS access tables?

  Hello

  I woke up in the learning of database in no time. I'm using Labview 9 to create a table based on DDMMYY hhmmss format. I can write data to the table in access. The picture will be 24 hours before a new table will be created. However, I find that this concept is not very gd as time goes by, I'll have a lot of paintings for example after 6 months.

  1.I would like to create a calendar (similar to the system clock) in labview, through which the user can click and select, which will then open and retrieve the data. Inorder to do I think I need to create queries and the relationship in MS Access? can any1 advice? Please give as much detail as possible.

  2.i can access data and display in labview. However, I want to display the data and plot in the chart. For instance, coloum b, c and trace on the graph in a proceeding for the analyst.

  3. how to generate a report to an email in a file to document the daily data inserted. I can do it in labview?

  Any help would be much appreciated.  If you have examples of code and don't mind not to share, I would be very grateful.

• The question of performance - cached data from a large table

  Hi all

  I have a general question about caching, I use an Oracle 11 g R2 server.

  I have a large table on 50 million lines, which is very often consulted by my application. Some query runs slowly and some are ok. But (of course) when the data in the table is already in the cache (so basically when a user asks the same thing twice or several times) it works very quickly.

  Does anyone have any recommendations on the caching of data / table of this size?

  Thank you very much.

  Your user name has run a query to return the lines 68 000 - what type of user is, a human being cannot cope eventually with that a lot of data and it's not entirely surprising that he might take a long time to return.

  One thing I would check is if you still get the same execution plan - Oracle here estimates are out by a factor of about 95 (7 100 vs 68 500 returned planned lines) may be a part of your change in the calendar refers to plan changes.

  If you check the numbers you will see about half your time came to survey the unique index, and half visited the table. In general, it is hard to beat Oracle to cache algorithms, but the indexes are often much smaller than the paintings they cover, so it is possible that your best strategy is to protect this index at the expense of the table. Rather than trying to create a cache to KEEP the index, however, you MIGHT find that you get some advantage to create a cache of RECYCLING for the table, using a small percentage of available memory - the goal is to arrange things so that the table blocks that you revisit do not grow the index blocks that you will come back to memory.

  Another detail to consider is that if you visit the index and the table completely random (for 68 500 sites), it is possible that you find yourself re-reading blocks several times during the visit. If you order the intermediate result set of driving all table first you find you're walk the index and the table in the order and that you don't have to reread all the blocks. It's something that only you can know, however.  The code will have to change to include a view of inline with a dash of no_merge and no_eliminate_oby.

  My best results are that I have data in the first table, but none in the two tables joined.

  I'm asuming it has to do with the way im insert the data, but after some research, I've seen others have had similar problems, what I did not understand.

  I'm sure that this is a problem common just need advice.

• Inserting data in several related tables using the database

  Hello world
  I'm working on a BPM application using Oracle BPM 11.1.1.5.0 and JDeveloper 11.1.1.5.0.
  
  In my database, I have two tables, loan and guarantee that are related by a field named employeeID (PK on loan) and FK in warranty.
  Each line can have several lines of guarantee.
  
  At this point, I'm doing an entry form for the user to insert data in the two tables.
  
  I did successfully before with a single table that has no relations.
  
  The way I'm doing here is, after the creation of the database successfully adapter, a type of LoanCollection is created in the types module, which can be used to create business objects and data objects of.
  
  The problem is when I create an object of type loanCollection process data and then create a UI generated automatically on that basis, only the fields in the primary table (the Table of loan) appear in the form.
  On the other hand, if I create a business object based on the LoanSchema, the form for all of the two tables is created automatically (the loan as a form, the guarantee in a table), but then, when I try to access it in the section processing service mission which calls the database adapter, I have no access to such.
  In fact, the only type which can be used in the service task is the process based on the loanCollection data object.
  
  To summorize, I have to use the type of business for my UI object to include all the fields in both tables, so I have to use the data object from the collection process in the transformation of service task dialog box.
  And I can't find a way to map to another.
  
  Can someone help me with this please?
  Thank you very much

  Try to follow these steps.

  1. create a new module in your catalogue our BPM project management section
  2. in this new module create 3 Business Objects - (LoanBusinessObject, GuaranteeBusinessObject and GuaranteeArrayBusinessObject)
  3. Add the attributes appropriate to the LoanBusinessObject and the GuaranteeBusinessObject so that they mimic your database tables, then to the GuaranteeArrayBusinessObject add an array of type attribute GuraranteeBusinessObject
  4. now you need to create two process data objects, type loanProcessObject LoanBusinessObject and type guaranteesProcessObject GuaranteeArrayBusinessObject
  5. as inputs to your human task adds the loanProcessObject and guaranteesProcessObject, these should now be available in your data controls and can be used to auto generate the form
  6. in your dbadapter you'll then use XSL Transformation and use for each so that it will write the data to the ready table and all the line items of warranty for the warranty table.
