Column data type not supported
Hello
I have Oracle 12 c installed in my system. I created an SP that returns a Table when I try to run it in SQL Developer, it gives me the correct results, but when I call it my DOTNET application it gives me the error-'datatype of the column unsupported. I'm trying to fill a dataset using a data adapter. To check I commented all the code in the procedure and returned the table using the code below.
Declare rc sys_refcursor; Begin OPEN rc FOR SELECT 'Sayam' AS "Error" FROM dual; SYS.DBMS_SQL.RETURN_RESULT (rc, TRUE) ; END;
But the problem was still same. This is the track of the same thing.
Oracle.ManagedDataAccess.Client.OracleException took

"of data type not supported" in the interactive report
Hello
I'm trying to download a file from a link to an itneractive report.
In the section "attributes of report" interactive column, I defined in the section "links" in a column of the 'target', 'URL', and the URL like this:
When I run the interactive report, the link view this:DOWNLOAD:CONVENTIONS:#FILE_BLOB#:#ID#::#MIME_TYPE#:#FICHIERS#:#LAST_UPDATE#::attachment:Conv
Download: CONVENTIONS: [type]:188:C22.pdf:attachment:Conv of data not supported
The table "CONVENTIONS" is defined as follows:
......
ACTIVATE THE 'ID' NUMBER NOT NULL,
VARCHAR2 (2048 BYTE) "FILES."
'FILE_BLOB' BLOB,
"LAST_UPDATE" DATE,
'MIME_TYPE' VARCHAR2 (255 BYTE)
Where is my mistake?
Thanks for your help!
ChristianHello Christina,
Sorry Wizard, you need to use is the "form > form on Table with Report", because the normal create assistant interactive report allows you to enter a query.
Once you have completed the wizard, take a look at the generated SQL statement (must use the dbms_lob.getlength) and the value in "number Format / Date" for this column.Concerning

Confusion of length of column data type
Hi all
To learn about my column data type and length, I have run the following query. However, when I confirm it with the table_name desc command, I see that the lengths of data do not correspond. You have an idea?
> > select column_name | » '|| DATA_TYPE | » ('|| ( data_length|') ' col_info all_tab_columns where table_name = 'CUSTTABLE' and column_name = 'ACCOUNTNUM;
> > ACCOUNTNUM NVARCHAR2 (24)
> > desc CUSTTABLE.
> > ACCOUNTNUM 1 N NVARCHAR2 (12)

By the way I couln t understand what were you thinking when you explain to no.
I missed you NVARCHAR2 column and thought it was VARCHAR2. When you declare the semantics of VARCHAR2 column length is specified explicitly or implicitly. Explicitly suffixing length with BYTE or CHAR and implicitly when you specify the length of the right itself. Then length is based on the value NLS_LENGTH_SEMANTICS session. So let's assume you generate table create statement (and it seems that you is, based on column_name |) » '|| DATA_TYPE | » ('|| ( data_length|') ' ). Then it does not matter if use use data_length or char_col_decl_length. It will be regadless semantics implied length of what you use. Therefore, when you run create table instructions column length will be interpreted as bytes if current NLS_LENGTH_SEMANTICS byte value. But same length is interpreted as the characters if current NLS_LENGTH_SEMANTICS a char value. As you can see, in order to generate create table statement we use explicit semantic length column, otherwise create table statement can produce lengths of different column in the source table.

How can I check, it's a table really compressed or OWM not in?
Hello
This is the right way to determine whether a table enabled version uses compression. It could be another property table or tablespace that causes the same error will be triggered. It is difficult to know exactly without the full table DDL. If the dba_tables query was ACTIVE for this column, the inner workings of the Workspace Manager would have to set as unused column instead of a fall that could have prevented this error. This behavior has been updated in 12 c to always define the column as unused anyway. As a on 11.2.0.3, you can use ignore_last_error to jump the abandonment of all columns of metadata (version, nextver, delstatus, ltlock and createtime/retiretime if history is used). Then when DisableVersioning is complete, you can issue the unused column from the game DDL manually for each of the columns.
Kind regards

Timestamp for date columns data type are not imported in discoverer admin
Hi all
Someone you will suggest why timestamp data type columns are not imported into admin. discoverer other types of data import you correctly, but the timestamp data type columns are missed.
Please let me know to change the type of data is not possible at this time.
Thank youHello
You will be disappointed because the timestamp columns are not one of the recognized data types supported by the discoverer. He acknowledges only dates, strings and (integer and decimal) numbers.Maybe you could put up a view that matches the table you use, convert the timestamp in a rather ordinary date?
Then, inside your end-user license, all you would have to do is redirect the folder to view.
Best wishes

XMLTable: definition of the columns data type of table
Hello world
I am using ORACLE 11 g and you want to shred XML into a table called test used. I was hoping I'd be able to get the types of data to the employees table existing instead of specify them in the clause of columns. Is this possible?
Here is an example of what I'm trying to do. But I get an error: PL/SQL: ORA-00907: lack the right parenthesis on the line starting with columns.
Error detailsinsert into EMPLOYEES select * from xmltable( '/employees/employee' passing EMP_XML columns FIRST_NAME EMPLOYEES.FIRST_NAME%TYPE path 'first_name', LAST_NAME EMPLOYEES.LAST_NAME%TYPE path 'last_name', GENDER EMPLOYEES.GENDER%TYPE path 'gender', AGE EMPLOYEES.AGE%TYPE path 'age' );
Thank you.columns FIRST_NAME EMPLOYEES.FIRST_NAME%TYPE path 'first_name', * ERROR at line 16: ORA-06550: line 16, column 42: PL/SQL: ORA-00907: missing right parenthesis ORA-06550: line 11, column 5: PL/SQL: SQL Statement ignored
Specification of column names is required, but you can omit the declaration of data types.
See: the function XMLTABLE SQL/XML in Oracle XML DB
XMLTable is used with storage XML based on a schema of XMLType data type is optional. If absent, the data type is inferred from the XML schema. If Oracle > XML DB is unable to determine the right type of a node, a default type VARCHAR2 (4000) is used.
It is an Oracle extension; in the SQL/XML standard, the data type is always required.
Note:
The alleged data type might change as a result of the application of a patch or upgrade of Oracle XML DB. In particular, a new set of release or patch might be able to > determine the data type when the previous version was unable to do so (and therefore not reimbursed to VARCHAR2 (4000)). To protect against such an eventuality, specify an explicit data type with the data type. -
I've just updated all my FF browsers to the latest version and now regret it.
Can I go back? Security be doomed, because I manage a daily site and use jpg all the time. When I open Joomla to create my new assignments, the FF browser now blocks the download of all the jpgs on my web server. Safari has still properly download jpg files, but does not allow other manipulations of images (when I work in Joomla).
(1) can I fix in FF
(2) if not, can I go back to a previous v. of FF if I now v. 12?You have the option to update PVE? This thread suggests she could solve the problem: Joomla! - View topic - problem downloading photos in the JCE Editor. Another suggests to disable a different download option (but that means nothing to me): type file not supported - file: undefined. Extended image 2.0.2 Manager.

Hello
You need to open ZIP files, which are compressed to make it smaller, then use the content
in the application appropriate - so if the audio or video content can use WMP.Compress and uncompress files (zip files)

ODI 12 - problem with missing data in the store column data types
Hello world
We have recently installed Studio 12 on Oracle RDBMS ODI. We have created some topologies, contexts and the logical architecture. We have created the necessary templates and made reverse engineering. The strange thing is when a model data store opening, we have noticed, the data types of its attributes are not displayed and cannot be selected in the drop-down list because they do not exist yet. You can see the image below.
So the mappings are not correctly executed because on the stage of the creation of work tables CREATE script was not generated correctly. (It's something like "CREATE TABLE < name > ()")
Anyone can give an idea what could be the reason for this and how might be solved?
Any ideas would be appreciated.
Thank you in advance.

Database application - direct incorrect column data type
Hello all-
hope you can help with this. I use the live database request in Oracle BI to send a complex query directly to our data warehouse. My problem is that the columns of results containing my measurements are converted by Oracle BI so they should be double. The conversion of integer causes decimals to round values, reading to incorrect results in my reports. I tried several tweeks to my request to allow OBIEE correct estimate on the data type, but nothing has worked.
Is there a way to force OBIEE to recognize the correct data type for a column in a query request to the live database?
Thanks in advance for you help!

Impossible to download a movie in Windows Movie Maker-file type not supported
I'm doing a movie with windows movie maker. It does allow me to download an audio file. It says it does not support the file and I need to download a codec. He didn't tell me what codec either. I tried to burn a cd of media player and import of this and it wouldn't let me not do it either.
I have exactly the same problem. How to convert the format?

Video on twitch.tv does not work. MIME type not supported.
Chrome and Internet browsers work fine. Only solution I found was to install flash player which I would rather. Another response, said that the problem is due to the beta version that is not the case here and to clear the data/cache that does not either because it is a brand new installation of the application on the device. Why is not able to play these video streams where other browsers have a Firefox problem? Please consider this because it's one of the reasons that I've completely switched to Firefox for my mobile devices.
"Twitch sends a stream of HLS (HTTP Live Streaming) iOS Chrome and Apple Safari at the URL /hls" rel = "nofollow" > http://twitch.tv/ < stream > /hls because that's what they are beta testing. We have no HLS streaming support yet but lean on it. To use shaking right now, you need Flash or any simply uses the native application of Jolt on Android, which is better than their desktop site functionally.

Compression type not supported error
I recently moved to a new PC in Win 7 64 bit first CS 5.5 from an old PC to Win 7 64 bit. Most of files loading projects and all seems well. However, in one or two projects some of the imported not files load correctly. When I try to import again I get a "compression type is" for the file. All files are imported and appear in the calendar of the project with its file name. They are all MTS files. Some appear and play correctly, but others have big red box indicating that the file does not appear in the timeline. The space reserved for this file is always in the timeline panel. All of creation and the MTS files are always in the same named folders as they were in the old PC. The MTS at the beginning of the timeline files are those that failed. At a given time in the timeline panel. following the end of chess and the MTS files appear will work perfectly. Dates of creation of the failed files are all in 2010 and earlier versions, the right files are from 2013. All were made with the same HDV camera. It's a puzzle. Any ideas?
