I work with perl and sybase. I try to create view in perl:
if(condition)
create view name_view
as select col1,col2,col3
from table1,table2
where key1=key2
else (condition)
create view name_view
as select col1,col2,col2
from table1,table3
where key1=key2
And when I run it, I always get an error, that view is already exists.
Even I put an if - exists condition.
drop view name_view
it is always the same error.
Please note: I cannot create a view in separate query, because when I select from view, it works very slow.
I would recommend using prepare and execute call. Please read this excellent post from PerlMonks.org

We are using Optimizely/Episerver CMS 11.20. When trying to export a page hierarchy from our production environment and then import the resulting ExportedFile.episerverdata file to our acceptance test environment I get the following error:
[Importing content 70725_133679] Exception: Object reference not set to an instance of an object.
I have no idea what 70725_133679 is referring to. Is there a way to look this up, e.g. via an SQL query against the "EPi" database?
It refers to a specific version of some content (which could be just about anything).
You could try to browse to https://yoursite/EPiServer/CMS/#context=epi.cms.contentdata:///70725_133679 (note the ID at the end) to see which content it is.
Got another answer on a Optimizely forum (thanks to Surjit Bharath):
The following SQL against the EPi database gives information about the referenced content:
select * from tblContent where pkID = 70725
select * from tblWorkContent where pkID = 133679
This too points to a submit button. I have yet to understand why that block would cause an exception during import, but now I at least have a place to start digging.
I am using a FlexColumnLayout for my app.
In the mid column I need to access a controll of the begin column of the FlexColumnLayout. Here is the problem:
Since it is a different view I cannot use
this.getView().byId("myId")
My first solution was to use stable ID's, by giving the views (XML) IDs.
Like that I could use:
sap.ui.getCore().byId("application---viewId--myId")
At first it worked just fine, but now that I integrated my app into the fiori launchpad the first part of the stable ID (the part before "viewId") changed and when I transport into productive it will change again.
Is there a way to access the mid column controls without sap.ui.getCore().byId?
Or is there a way to load the first part dynamically so I don't need to change my IDs when tranporting?
Sadly I don't know how to reproduce a Launchpad for testing purposes, but for those who want to test their ideas about my problem, my FlexColumnLayout is build just like in the DemoApp: https://sapui5.hana.ondemand.com/#/entity/sap.f.FlexibleColumnLayout
Ok guys i found a solution:
this.getView().getParent().getParent()
returns the FlexColumnLayout. This has a method called "getBeginColumnPages", which returns an array of the views representing the begin column. Now that i can access the view in which my control is found, i can access it with the sap.ui.core.mvc.View.byId() method.
Now I have
this.getView().getParent().getParent().getMidColumnPages()[0].byId("myId")
Since the doulbe .getParent() doesn't seem to be ideal, please post a better solution if you know one : D
You have to use createId() function, this will return the complete ID of your control.
this.byId(this.createId("myid"));
I am trying to create a Hierarchical block using the GNURadio Companion GUI. Answers I've found in other posts say to select the blocks you want to incorporate, then go to More -> Create Hier. Then a new screen is supposed to appear. However, doing "Create Hier" with any combinations of blocks selected seems to do nothing.
Am I doing something wrong, or is there a problem with my GRC?
It's very simple. You just start with a new flow graph in GRC, and use Pad Sources as input, and Pad Sinks as output.
If you want to let the user configure something, use a Parameter GRC block.
You must set the Generate Options in the Options block to Hier Block, and set a sensible ID there, too – don't stick with top_block, but use something (without spaces or -; it needs to work as a python name) that won't conflict with something else.
Here's an example:
You can then Generate button (or press [F5]), and then, after you've done a rescan of your block library with the refresh button you can find (and use) your new block in the Block Category you specified.
This is the first time I'm encountering GetLayoutObjectAttribute and I am having serious issues with it. My variable $web won't set. I think it's because PD_WebV isn't the right object name to refer to, but I don't know how to find the right object name. I can't find the objects name when I hit Edit Layout, so does anyone know how to find an layout objects name?
Loop
Pause/Resume Script [Duration (seconds): 1]
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
If[$Web="done"]
#execute if statements
After Edit:
After some troubleshooting, I found out that PD_WebV is the right object name to refer and it's refered to correctly, so my new question is why doesn't the script go to the line If[$Web="done"] and how could I fix it? Ss my If statement not evaluating something it should be? Is my $web variable never set to done or is the issue something completely different? Would the problem possibly have to do with my WebDirect sharing settings? Any guidance would help. Thanks.
After, After Edit:
So now that my application is getting past Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")], the variable $web only equals <HTML></HTML>. Does anyone know a way, without using javascript, to test the inside of the html tags?
Also, I printed the bounds of the webViewer PD_WebV that I can't locate on the layout but am referring to in the script. The bounds that are printed are different each time I run the script. Is the usual or unusual? My source is also about:blank so it doesn't look like I'm sourcing from a URL
Is my $web variable never set to done or is the issue something
completely different?
If you're doing:
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
then the only time
$Web="done"
will return true is when the web page loaded into your web viewer contains exactly the string "done" (in practical terms, that's never).
I have already suggested in a comment that you test for:
PatternCount ( $webpage ; "</html>" )
This is assuming you want the subsequent steps to execute only after the page has finished loading. The entire script would look something like this:
Loop
Pause/Resume Script [Duration (seconds): 1]
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
Exit Loop If [ PatternCount ( $webpage ; "</html>" ) ]
End Loop
# execute statements
You might also want to add a counter to the loop and exit the script after n trials.
Ah, I reread your question.
To set the object name for your webviewer so that the GetLayoutObjectAttribute function works you need to set it in the Name field in the inspector when you have the webviewer selected.
e.g.:
After that your variable should populate.
Be aware
What it will populate with will be all of the html from the browser, i.e. not a boolean true/false liek your conditional suggests.
I'm not sure exactly what you're trying to accomplish, but to be able to determine a result from your web viewer you'll need to either parse the HTML to see if it's content contains what you're looking for or within the code you're setting the webviewer with, fire a javascript function that calls back to the FileMaker file using a FileMaker url.
So, using SSDT on Visual Studio 2013, I can specify a Database name...
create view vSample1 as
select * from [$(RandomDatabase)].dbo.TableName
I can also do this with a four part name
create view vSample2 as
select * from [$(RandomServer)].[$(RandomDatabase)].dbo.TableName
But when I try to do this with the TableName, I get errors...
create view vSample3
select * from [$(RandomServer)].[$(RandomDatabase)].dbo.[$(RandomTable)]
It gives me an error similiar to
Error: SQL71561: View: [vSample3] has an unresolved reference to object [$(RandomServer)].[$(RandomDatabase)].dbo.[$(RandomTable)].
I've been looking at the SQLCMD variables window in the project settings and have verified that the $(RandomTable) variable is defined as TableName, but it still gives me build errors.
Why is this, and how do I fix it?
Thanks
I would use pre/post deployment script to create such view using sp_executesql and dynamic query.
exec sp_executesql N'create view vSample3 as
select * from [$(RandomServer)].[$(RandomDatabase)].dbo.[$(RandomTable)]'
I would use synonyms - create a table which matches the actual table and create a synonym that points to that, then reference the synonym in the view or just reference instead of the view. You need this so you get it to compile and you get the good stuff like references etc.
Then when you deploy to each server just deploy the correct synonym to the correct server.
(Then kick your vendor in the b&DD$ for such an annoying system)
