How do you include CLOB data in XML document? Is there a size limit?
Im actually using the Oracle API's to create an XML document as a clob.
But for the columns that are CLOB columns they just put
<column>(CLOB)</column> in the document and not the actual CLOB.
Anybody know the direction I need to resolve this?
Could you post the code that is causing this?

How do you include date in PDF export from Keynote 6.2.2
In Keynote '09, I used to be able to insert the date in the bottom of a PDF export. Now that I upgraded to Mavericks, Keynote (6.2.2) appears to only have the option to "include name and date".
That's a useless combination. Those are 2 different things: (1) the filename, and (2) the date. At best, those should be two separate checkboxes.
I miss the feature to add ONLY the date to the PDF generated. I haven't upgraded to Yosemite yet but don't have my hopes up that this feature exists.
Am I missing something? How can I include the date in a PDF exported/printed/saved from a Keynote presentation?Events are purely automatic, and will only organise on the date and time.
Make an Album of the photos and then you can drag them to any order you want.

How Get JDev to Omit data-sources.xml from every .war deployment
I want a global data-sources.xml file to be used for all deployments. I do not want a copy of my standard data-sources.xml file to be included in every single deployment. I want my global data-sources.xml file to reside in the standard J2EE location of:
oc4j_home/oc4j_instance_name/j2ee/config/data-sources.xml
JDeveloper, for whatever reason, includes a data-sources.xml into every .war file. How do we configure JDev to omit the data-sources.xml? How do we set up JDev to automatically configure the .xml files (orion-application.xml, application.xml, etc) to use the global data-sources.xml? I do not want to manually do this for every deployment.
I've been trying hard to find the answer in JDev online help and other OAS manuals. I read everywhere that I can have a "global" data-sources.xml, but I find no way to easily configure JDeveloper to do it this way.
I would be grateful for you insights/help.
thanks
-Paul JandaI found the answer:
In JDeveloper, Go to Tools | Preferences
Select Deployment
Uncheck the option for "Bundle default data-sources.xml during deployment"
Upon the next generation of the .ear or .war file (including the next deployment), data-sources.xml will be omitted.

How do you merge the data of two MIDI regions?
How do you merge the data of two MIDI regions into one MIDI region without using copy and paste functions in the piano roll editor?
Sorry - didn't make myself clear. The glue tool would be no good here. I meant that I wanted, for example, to merge the MIDI contents of two regions that are perhaps on different tracks but play back at the same time, i.e. I want to add the 2nd region's MIDI to the 1st region's MIDI, but without having to go into the piano roll editor and cut and paste the data.

Hi,
Is there a standard way (or maybe encoding to be used) to include
binary data in an XML document? I am interested in both inline
inclusion and external inclusion.
Thanks.
- sam
nullThere is no way to include binary data within the document;
however it could be referenced as an external unparsed entity
that resided in a different file.

You'd need an app that can edit EXIF data. You can't do that natively on an iPhone but there may be apps in the App Store that will let you do it. Take a look at Snapseed. I think it might.

How do you make your data into a chart?
Dick,
Your table should look like this:
You're looking at 1 Header Row and 1 Header Column. Headers are shaded by default. Adding a shading to a regular column doesn't make it a header. Use the Table Inspector.
When you Select the data and Insert a Table, you will get this:

How to fill an oracle CLOB with a XML document using Unicode UTF8
Hi,
I'm working with C# and oracle database v8.1.7 (release 3), and i'm having some problems to fill correctly an oracle CLOB parameter with XML document using UTF8 encoding.
It works fine with "Encoding.Unicode" but not with "Encoding.UTF8". The problem is that i can't use Unicode (UTF16) with oracle 8.
Can someone help me ? Thanks.
Here is my code.
OracleTransaction tx = conn.BeginTransaction();
OracleCommand cmd = conn.CreateCommand();
cmd.Transaction = tx;

cmd.Parameters.Add(new OracleParameter("tempclob", OracleType.Clob)).Direction = ParameterDirection.Output;
cmd.ExecuteNonQuery();
OracleLob tempLob = (OracleLob)cmd.Parameters[0].Value;

HOW TEXT CAN BE MADE SUBSCRIPTED IN XML DOCUMENT?
SIR,
I WANT TO DISPLAY MATHEMATICAL FORMULAS,WHICH INCLUDE MATHAMATICAL NOTATIONS LIKE "SIGMA" "DELTA" AND SO ON, AND ALSO SYMBOLS WITH SUBSCRIPTED TEXTS OR LETTERS,IN XML DOCUMENT.
MY PROBLEM IS HOW CAN WE RENDER SUBSCRIPTED TEXTS IN XML DOCUMENT.
FOR Eg.CONSIDER THE FORMULA SHOWN BELOW,IN HTML FORMAT.
ÓAli * Bli / Cli
PLEASE,TELL HOW THIS CAN BE REPRESENTED IN XML DOCUMENT.
AND ALSO TELL ME HOW CAN A HORIZONTAL RULE BE DRAWN IN XML DOCUMENT
THANK YOU.Ouch. Would you please not type in all capitals. It's hard to read.
Anyway the question doesn't make sense. XML is just a format for storing and transmitting data. XML doesn't have the concepts of subscripting and drawing horizontal rules. Perhaps you were thinking of HTML? -
Searching CLOB column of XML documents with leading wildcard - Performance
Hi, our table has a text indexed CLOB column of XML documents and when performing a search with a leading wild card, we never retrieve any results.
The query looks like this:
select id from <table> where contains(columnname, '(%12345)') > 0;
I cant even generate an explain plan from this query. I killed it after 39 minutes.
If the query changes to:
select id from <table> where contains(columnname, '(12345%)') > 0;
I get an explain plan immediately with a cost=2 and when I execute the query, I get results in less than a second.
I'd appreciate any thoughts of what I should check or what the problem might be.
Thanks! DougCan you provide a script that reproduces the case. I am unable to reproduce the problem with just some small sample data, as shown below. That means that there is nothing wrong with the syntax, but you may be having problems due to the size of your data or other parameters that have not been mentioned.
