Can you compare your design to you DB.

Hi,
I would like to know , if it is possbile to find the differences between my design and the database and from there generate the DDL
so my DB can be in syn with the design
Thanks.

Hi,
If you originally imported your design from the database, you can use the Synchronize feature to compare your design and the current database definition, and to generate the DDL:
First open your design in Data Modeler and make sure the relevant Physical Model is open too.
When the Relational Model diagram is being displayed, select the right-pointing arrow above the diagram ("Synchronize Data Dictionary With Model). This will display the Compare Models dialog showing the differences.
You can select which differences are relevant (in the left-hand tree in the dialog), and use the "DDL Preview" button to generate DDL to update your database.
If the design was not originally imported from the database, you can do the comparison as follows:
First open your design (and make sure the relevant Physical Model is open too), and then use File/Import/Data Dictionary to import the database definitions. As you want to to generate DDL to update your database with the differences, you should set the "Swap Target Model" option on step 2 of the Data Dictionary Import Wizard.
After the Import phase, this displays the Compare Models dialog, showing the differences between your model and the definitions imported from the database.
As before, you can then use the "DDL Preview" button on this dialog to generate the DDL for the differences.
In the lower part of the Compare Models dialog, you can select the Options tab. The "Compare Options" tab allows you to select options used in the comparison (e.g. whether the owning Schema is significant, or whether differences in the order of columns is significant) - if you change these options, you can use the Refresh Trees button to update the comparison trees.

  • Crystal Report XI: Can you write your query in SQL instead of using the GUI

    Hello
      In crystal report version XI, can you write your query in sqlplus and then use the crystal report designer to build your report instead of using the GUI . I would like to be able to go database and show sql query and open that query and make changes directly there, is that possible on this version, if yes is there a setting somewhere? Please let me know.
    Thank you
    alpha

    Moved to Database forum.
    No you can no longer modify the SQL directly. Use a Command Object to enter the SQL directly.
    Thank you

  • How can you keep your iPhone 4 (using it as my car's iPod) staying on the Audible app?  When I leave the car and return to continue hearing a book, it has switched to iTunes.

    How can you keep your iPhone 4 (using it as my car's iPod) staying on the Audible app?  When I leave the car and return to continue hearing a book, it has switched to iTunes.

    The first time an iPhone is connected to iTunes that is used to sync with another iPhone or iOS device, you are prompted to transfer the backup for the other iPhone or iOS device or to set up the iPhone as a new iPhone.
    The former does as provided - it transfers the backup for the other iPhone or iOS device to the iPhone replacing all data on the iPhone that is included with the backup being transferred. The latter does nothing allowing you to make your various selections for the iPhone sync preferences with iTunes.
    This is designed to be done right away with a new iPhone.
    If you don't have a backup for the iPhone with iTunes on your computer and don't have an iCloud backup that hasn't been updated since choosing to transfer the backup for your iPod Touch to the iPhone, the data that was on the iPhone is gone.

  • Where can you compare 2 photos side by side in Full Screen in Elements 11?

    Where can you compare 2 photos side by side in Full Screen in Elements 11? Version 9 has this feature under Display View.

    In the Organizer select two thumbnails and hit the F12 key to compare them. But I guess you mean in the Editor application. In Expert Mode it‘s possible to work with floating windows rather than fixed tabs but you first need to set your preferences. Go to:
    Edit >> Preferences >> General (Windows)
    Photoshop Elements Editor >> Preferences >> General (Mac)
    Then put a checkmark in the box against “Allow Floating Documents in Expert Mode”
    Click OK
    You can now open your two images and use the layout button at the bottom to choose various configurations or to cascade.

  • Can you convert your desktop site plan into the phone & tablet version w/o re-creating the pages?

    Can you convert your desktop site plan into the phone & tablet version without re-creating the landing pages? This seems too extensive to have to re-design each page?

    Cwsnell,
    On your nav bar there is a shorcut to other pages.
    The most effecient way I have found to do this from the phone layout,
    click on the page icon shown above
    type in the name of the page (and select the desktop version as indicated by the icon of the monitor)
    select all on that page (CTRL A / Command A) and copy (CTRL C / Command C)
    revert back to the phone layout page and paste (CTRL V / Command V)
    then resize, delete what you dont need, make any other edits and your done!
    There is not a way to copy a page entirely over.  The mobile version should have less information and less imagery to enable fast load times.

  • Can you "auto smooth" your drawing as you're drawing?

    When I draw on the computer, it's always very sketchy looking, even if I'm using my tablet. I'm learning vectors right now but I'd rather draw at the moment. Nevertheless, I was wondering if there was a option or tool in adobe's arsenal, that makes it so, as you draw, adobe is autocorrecting your lines to make everything smooth and not jagged? Does this "autosmoother" even exist? I hope so.
    P.S. Can you guys recommend me some good sites/videos that teaches you how to use vector to it's fullest and how to start a website?
    Thanks in advance!

    AI has some "auto smoothing" options, but do not know of such in PS. Now, AI will be Vector art.
    In Corel Painter, you can also invoke similar. Painter is a pixel-based Raster program, and is designed for "natural media" drawing.
    Good luck, and maybe others will have tips on something I have missed.

  • Hi i am trying to make a cut path from a jpeg i designed in photoshop so that i can cut a sticker on my plotter of the jpeg  can you help

    hi i am trying to make a cut path from a jpeg i designed in photoshop so that i can cut a sticker on my plotter of the jpeg  can you help

    Peter,
    The cleanest way is to lock your imge, the draw the cut shape with the Pen Tool, set Fill to None and a suitable Stroke Weight. For rounded paths, you ClickDrag Handles out from carefully chosen Anchor Points all the way round, ending where you started. You may adjust the position of the current Anchor Point while you draw by pressing the Spacebar, which lets you freeze the Handles and move the Anchor Point about; you can Ctrl/Cmd+Z to go back, and you may start over. To practise with the Pen Tool, you may try some (outlined) letters from a font with serifs, or any relevant curved path that resembles the desired cut path for the image.
    Or, if you have a distinct colouring where you want the cut path, you may Object>Image Trace the image with the right settings (including creating (stroked) paths, then expand and delete everything but the cut path.

  • Can you edit text after saving your file as pdf

    I have recently created a letterhead in Illustrator.
    Is there a way to change a person name and title after saving it as a pdf file? I heard something about creating a form in Acrobat professsional.
    I need to print out a letterhead with different peoples name and title. Any help would be appreciated. Thank you.

    Can you edit the text in Acrobat Reader?
    Yes, if you use Acrobat Pro to save the PDF as a Reader-enabled form.
    1. Create your letterhead in Illustrator (or whatever). Leave design space for, but do not create text objects that you want to be editable.
    2. Save as PDF.
    3. Open the PDF in Acrobat Pro. Use Acrobat's Form tools to add text fields whereever you want the end users to be able to key text.
    4. Select the Enable Reader Usage Rights command in Acrobat to make the form fields edtiable in Reader. Save the file.
    Recipients of the PDF can now open it in Reader, edit the content of the fields, and save the file with their edits.

  • "You can't compare a date with a number" in a formula that worked in Excel

    I opened in Numbers an invoice file which was created in Excel. Formula returns hours worked. It has an "if" condition for the date field. I am assuming that that is the reason I get this "You can’t compare a date with a number because their data types are different." What do I do?
    Formula reads =IF(SUM(A11)>0,(D11−C11),"") where A11 is a date and D11- C11 are times, ie 4PM and 5PM
    Message was edited by: iamzoran

    Jerrold Green1,
    I agree with your words about using Sum with a single cell [have no idea why the "creator" of the file did that]; same for the parentheses enclosing subtraction. Yet cleaning it up as you showed me [=IF(A11>0,D11−C11,"") ] I got the same comment
    "You can’t compare a date with a number because their data types are different."
    Makes me think that t quinn is on to something with his "think the issue is with the expression ">0". Could it be that >0 is the number referred to and <>"" and ISBLANK are not numbers?!

  • Can you utilize Time Capsule to backup Windows 7 files simultaneously with Time Machine backing up your MacBook?

    Can you use the Time Capsule 2TB to backup files from a PC (using the standard backup program in Windows 7) while also using the TC 2TB to run Time Machine to backup a MacBook?

    Yes, it will work fine.. at least until the disk starts to fill up, then the expanding size of the sparsebundle can cause issues with the files from windows.. Pondini has made note of the issues..
    http://pondini.org/TM/TCQ3.html
    but I have to admit to doing precisely what you are talking about without problems.. as long as you maintain space.. plenty of space. Time Machine is eventually designed to use up all space on the TC.
    You cannot partition the TC drive without opening the TC and breaking warranty.. but you can create a disk image and put your windows backups inside it.. that might help to prevent issues.

    can you record your voice in logic pro 9 just as simple as garageband or do you need a plug-in or interface?

    Alas, poor Logic, I knew him well.
    Recording wise, It will be much the same as Garageband but you will need to read manuals as Logic doesn't set things up for you. You must choose input and output devices, create the correct tracks. Logic was designed for professional use so it expects users to be somewhat familiar with recording/editing techniques, in other words, won't hold your hand or be nearly as easy to use.

  • (261705413) Q RPCC-21 Can you compare a performance of "usual" RPC from EJB and RPC from Web Services?

    Q<RPCC-21> Can you compare a performance of "usual" RPC from EJB and RPC from Web
    Services?
    A<RPCC-21> There are additional performance overheads for invoking a web service
    when compared to straight EJB invocation. However, you should not think of web
    services as a way to replace your EJBs instead you should be willing to accept
    some performance decline for the massive gains in platform interoperability and
    the ability to exposure your services outside of you firewall.
    Additionally, performance decreases will be dependent on several factors. The
    most significant of which is the XML-Java and Java-XML translation of the SOAP
    message. This can be very fast if the XML structure is simple but if you web services
    requires a parameter that has a complex XML format you may see a more significant
    slow down.

    Sorry if this sounds like I am new to this but I am.
    So, the extended version is the format that would be used if you were not utilizing the files that the wsdl2java function creates?
    And this is done to when you want more flexibiility for the user to call your service?
    So, you would push to have the stub files used when you want to control how the web service is used?
    thanks for the feedback.
