How can I include a link to the remote database as a variable in pl/sql?

I am writing a new procedure for the parcel and it can be run on different environments. Excerpts from the main query in a table via a database link. I created variables to identify the owner of the current scheme, the owner of the remote table and the database link remote. The problem I have is to put this together in the main query for example.

PROCEDURE check_table
AS

v_schema_owner varchar2 (30);
v_database_link_owner varchar2 (30);
v_database_link_value varchar2 (128);
v_table varchar2 (500);


BEGIN

-Download the current schema owner-
V_schema_owner INTO SELECT username
Of user_users;

-The owner of the link database download-
Master_owner SELECT INTO v_database_link_owner
OF dba_mview_refresh_times
WHERE name = 'TEST_MV '.
AND the owner = v_schema_owner;

-Download database - link chain
Substr(master_link,2) SELECT INTO v_database_link_value
OF dba_mviews
WHERE mview_name = 'TEST_MV. '
AND the owner = v_schema_owner;

v_table: = v_database_link_owner |'. ' |' test_table@'|| v_database_link_value;


INSERT INTO check_table
SELECT trunc (sysdate) as check_date, 'Error of Test' as check_reason
OF v_table-* this is where he fails to compile * -.
WHERE texte_erreur like '% Test Failed ";

COMMIT;

EXCEPTION
WHEN NO_DATA_FOUND
THEN
NULL;

END check_table;


I get "table or view does not exist" on v_table. I tried to not have a variable v_table and set the string for the name of the table directly in the query, but it does not work. Only when I hardcode the owner of the table and the link doesn't it works but ideally I'd rather not have to do that.

Does anyone have any suggestions?

Thank you
GB

Hi, you use an EXECUTE IMMEDIATE to execute dynamic sql code

vSql := 'INSERT INTO check_table' ||
                ' SELECT TRUNC(sysdate) as check_date, ''Test Error'' as check_reason'||
                   ' FROM '||v_table||
                      ' WHERE error_text like ''Test Failed%''';
EXECUTE IMMEDIATE vSql;

  • How can I make my link 'See the product detail' of .swf in Dreamweaver

    Hi all:

    New to Dreamweaver.  This should be a simple click, but I can't.

    I made a button to 'See the product detail'.swf into Flash and I imported into

    product my Web page in Dreamweaver.

    How can I make a link to another page where the larger picture of the product is in Dreamweaver? /

    Thank you

    Ms. frustrated

    I made a button to 'See the product detail'.swf into Flash and I imported into

    product my Web page in Dreamweaver.

    I'm sorry to say, but I think it is a very bad idea.  Flash navigation elements are not good practices on the web, because you cannot be 100% sure that your visitor has the Flash Player on your computer.  In addition, the search engines don't analyze reliable these links for SERP purposes on the page.  Finally, any person using an assistive device to the screen will not be able to use these items.  Using a graph prepared in FW or PS, however, will not have these disadvantages and will be 100% reliable/useable for all categories (assuming that you have correctly provided a descriptive alt attribute for the image).

    How can I make a link to another page where the larger picture of the product is in Dreamweaver? /

    You can't do that in HTML - it needs to be done in the Actionscript of Flash at the moment you make the button. It is yet another reason why use Flash navigation items is a bad idea...

  • How can I include results of a subsequence, which takes place in a new thread in the test report from the main sequence

    Hello!

    I have ", working with the Version 4.2.1 of TestStand. I have a main sequence, which sous-séquences of different calkls. All these steps are reported correctly. One of the subsequences works like "new thread". How can I include his results in the common test report of the main sequence?

    I have variable markes of the subsequence as is required for the test report (it works OK if it's not a new thread). If the digital test, which is performed in this subsequence is correct, I get no results at all. If the digital test could not get a "message in red" who whithout having failed to test any reference to step somewhere in the report of the main sequence or values of vaiables that were not correct.

    I tried an option 'on the fly' in the Configuration of the report, but n ' got no useful result. What should I do?

    Best regards

    Hello Pericles,

    You can use a queue time for the results of the wire once it ends. Place a waiting time after the call to the thread in your MainSequence at the location where you want the results to add to the report (compared to other results). In the waiting step Setup tab, select wait: Thread the threaded sequence, and then select call to specify sequence call the radio button. You can also use an object reference if you need results if poster somewhere where elsewhere - you would just add an object reference to the appeal of sequence threaded in its thread settings dialog box.

    I hope this helps.

    Well, the way I would do is copy and paste the URL in the e-mail so that the recipient can click the link and get the right of the Web page.

    For example, I just googled 'horses' and there is the result of this research:

  • I would like to bring to the text from Word (and the web) which is already a hypertext link in InDesign. How can I do it while keeping the links active?

    I would like to bring to the text from Word (and the web) which is already a hypertext link in InDesign. How can I do it while keeping the links active?

    Whenever I have to copy and paste from the web or Word it removes hyperlinks.  And when I try to do in 'Place' ing a Word document in my InDesign project that it retains formatting with it, the rectangles around the text.

    I have the latest version of InDesign.

    Any help is appreciated.

    Copy-paste might not include the shaped. A regular import using square is the best way.

    The rectangles around the hyperlinks are just to indicate that they are links - they do not print, but they appear in your PDF.

    You can delete them by double clicking on the hyperlink in the hyperlinks Panel and select "Rectangle Invisible" as the type.

    In general, Word formatting of hyperlinks - blue text, underline - with a character Style. If you want to remove or change the formatting, all you have to do is to change the character style. My experience, however, is that you need to check all the hyperlinks because no reason apparent, sometimes they appear in the document without the character style.
