  If you need to have answers in another table:

  Student (student_id, name, etc...)
  Review (exam_id, exam_name, etc...)
  Question (question_id, exam_id, question_text)

  Response (question_id, a_text, b_text, c_text, d_text, a, b, c, d).<-- one-to-one="" with="" question="" table,="" a-d="" flags="" used="" to="" indicate="">

• SQL query in mapping to load the table from the warehouse

  Hi experts,
  
  I hope you can help me solve my problem. I already tried here in the forum how we can add a query in a mapping, but still not found the answer.
  In my store, I have a time dimension table that has a unique dimension key and all the date information. In my source database, I have a table for business information. In this dirty table, I have a field named date. This date will be in exact format.
  I also have a table sales in my warehouse which is almost a copy of the sales table from the source. I don't have that one more field in this table sale warehouse called "time_dim_key". This field should get the key of the dimension of the time dimension table warehouse based on the date of the sales table of source.
  Do I think a mapping, which includes:
  -the table sales source
  -the time of warehouse dimension table
  -the table of sales warehouse
  Normal fields can I directly table card sales from source to sale warehouse table.
  But the 'time_dim_key' of the table field dirty warehouse should fill up as:
  Select dimension_key in the warehouse_time_dim_table where day_date = source_sales_table.date
  Unfortunately I do not know how to include a query to get the exact date of this sale of source table in the mapping to fill the sales table from the warehouse.
  I hope someone can help me solve this issue.
  
  Thank you very much!
  Kind regards
  David

  take the Carpenter of the palette
  and create two groups
  1.warehouse_time_dim_table
  2.source_sales_table

  then, write the join condition,
  warehouse_time_dim_table.day_date = source_sales_table.date

  Who will solve the purpose.

  See you soon

• How can I get WIndows8 TouchSmart to boot from the recovery disc

  How can I get WIndows8 TouchSmart to boot from the recovery disc? With the recovery in the drive disk when I do a reboot or stop and start it does not read anything from the DVD player. My computer is a HP TouchSmart 23-D160QD.

  @AirForce9731,

  You may need to change the boot order to boot from the DVD drive first.  The steps to do this are in the document below.

  http://support.HP.com/us-en/document/c00364979

  These are recovery disks made by the recovery discs sent by HP?  They will not work in a different system (you will receive an error message), but you are able to get the boot floppies in a different system?  They should be able to start up to a point where the error message will be displayed.

• How can I sync 2 sony AVCHD images from the camera on the "date" as a prelude and import it in first pro?

  I have 2 sony camera popular with the AVCHD file structure. The two cameras are the same. How can I sync 2 sony AVCHD images from the camera on the "date" as a prelude and import it in first pro? Im working with 6.0

  
  

  Now I see the date taken in the import screen until I click "ingest". When in the trash, this option is there, but no metadata in there. It is therefore impossible to import images from two cameras and have these sorted.

  
  

  How can I get this sorted out before, so I can export for the first?

  Thank you. Tom van den Dool

  No, you won't lose your photos.  but you can prepare your catalogue for migration, http://helpx.adobe.com/photoshop-elements/kb/backup-restore-move-catalog-photoshop.html

  and if you follow the 7 steps you can download a free trial here: http://prodesigntools.com/direct-download-links-for-lightroom-3-and-photoshop-elements-8.h tml

  and activate it with your serial number.

  If you have a problem from the download, you follow the 7 steps, or your browser does not accept cookies.

  the most common problem is caused by failing to meticulously follow the steps 1, 2, and/or 3 (which adds a cookie to your system, allowing you to download the correct version of the adobe.com site).

  The same process.
  The method below would be easy to import.

  Expand the specific table in the physical layer, select any column duplicate and rename to actual or new column column and set the data type, save it.

• How to add channels to a channel table in the display panel in the script

  Hi all

  We try to put in place a review tool video using DIAdem, and we want to fill the results which have already been analysed in a Panel. This means populating a channel table in this Panel with the necessary data, but we cannot find a way to add strings to a table in the script. It seems that it should be very simple, but we can not find!

  Thank you

  Peter

  Hi Peter,.

  Yes, it's simple. You prepare your VIEW with the channel table layout and use the add on the columns collection method.

  The command might look like this:

  VIEW. Sheets (1). Areas (1). DisplayObj.Columns.Add("myGroup/myChannel")
