creating an external table
HelloI made an excel csv file, but some of the columns of the excel file are null, so I did type .dat
and when I try: select *.
from caen:
I get this error:
Error at startup on line 2 of the command:
Select *.
Caen
Error report:
SQL error: ORA-29913: error in executing ODCIEXTTABLEFETCH legend
ORA-30653: reject limit reached
29913 00000 - "error in the execution of %s legend".
* Cause: The execution of the specified legend caused an error.
* Action: Examine the error messages take appropriate measures.
I also have a comma after each line FRO this .dat file.
Can you help me to import this file?
Thank you
Some of your data values seem to have a comma in the data:
Cultivarea cerealelor (exclusiv orez), plantelor leguminoase si aplantelor producatoare de seminte oleaginoase
Cultivarea legumelor si a pepenilor, a radacinoaselor si tuberculilor
Cultivarea fructelor arbustilor fructiferi, capsunilor, nuciferilorsi a altor pomi fructiferi
Cultivarea condimentelor, plantelor aromatice, medicinale si aplantelor de uz farmaceutic
I suggest that you change your data file if you can so that text fields are surrounded with double quotes.

create an external table based on local drive
Hello world
Is it possible to create an external table and that it points to a file on my local drive?
It is perhaps a silly question. I'm sorry.
Thank you
Lydiea
In addition to the response of William Robertson (which is correct), if you do not have a way to make the server access to your local disk, you can use sql loader on your local computer to load the data into an actual table.

Creating the external Table - length fixed
I was responsible for importing data in fixed length of a text file in an oracle table. To do this, I create an external Table. I'm finally at the point where the script works to create the table, but when I run a statement select for ' select * from external table ', I have received only a single line/record (the first line of the text file).
This is what the script looks like:

Published by: zephyr223 on March 25, 2013 10:47Hello
Which characters do you have in your data file that define the "line break".Oracle documentation:
If DELIMITED BY NEWLINE is specified, then the actual value used is platform-specific. On UNIX platforms, NEWLINE is assumed to be "\n". On Windows NT, NEWLINE is assumed to be "\r\n".you have these 'hidden' characters in your folder or are they something else?

Helps to create an external table to a dashboard
I am creating a table in an external file that will receive and organize partitions from Quiz.fla when you click on the button to submit the results. I also want another fla file to reference the external table and pull 15 scores him and then view scores on a scrolling banner. I want the banner to be able update dynamically (I guess it would accomplish the reloading of the banner fla every time it reaches the end of its cycle, with the first load of the image of the outer table on an onClipEvent action), how it will update while remaining open. The main reason that I need two separate files for the quiz and the banner of the score is that they are displayed on two different monitors. What would be the most effective way to solve this problem? I know a little actionscript, but I don't have much experience with the call for data and functions from external fla or as files (table and function referring to the way in which the data will be organized inside the table will be in a file separate .as).
I currently work in AS2, since I had almost no experience with AS3.
Please mark this thread as answered, if it is closed.

It's funny, I never thought of parsing an XML through SQL * Loader before.
Are you aware of the XML DB features? They are intended only for what you are doing here.
Also, please look at function XMLTable. It allows you to directly map your XML file in columns and relational rows.
For example, by giving an example of file "book.xml" like this:
1 2 ABC DEF 1 3 XYZ TTT Then, just do:
SELECT * FROM XMLTable( '/GL_RECS/GL_REC' passing xmltype( bfilename('XML_DIR','book.xml'), nls_charset_id('CHAR_CS') ) columns status varchar2(50) path 'STATUS', ledger_id varchar2(15) path 'LEDGER_ID', segment1 varchar2(25) path 'SEGMENT1', segment2 varchar2(25) path 'SEGMENT2' ); -

Creating external Tables using the EXECUTE IMMEDIATE in PL/SQL
Hi guys,.
I am trying to create an external Table using the EXECUTE IMMEDIATE in a procedure and I managed to compile and no errors were generated. But when I try to run it from sql using the exec command I get the following error:
------------------------------------------------------------------------
ERROR on line 5:
ORA-00911: invalid character
ORA-06512: at "GEO. TEST_DDL', line 4
ORA-06512: at line 5
-------------------------------------------------------------------------
I tried to check the whole statement to create the external table, but I can't find where is the error. Surprisingly, if I simply run the command table create external on sqlplus it works, but not a procedure.
If anyone can help with ideas or experience?
Geoffrey KossamiThe error means that there is an identifier somewhere that starts with a nonalphanumeric. This is a typical mistake of editing. A procedure compiles correctly is not of course because the underlying dynamic sql running is OK. Which of course only be resolved when you try to run it.
There is certainly a problem with the text you provide to be run as a piece of dynamic sql code. You should try to watch it with dbms_output and run this code in sqlplus. But your problem is with the code you run as dynamic PL/SQL, it is not itself compilable.

You need to carefully examine the description of the PREPROCESSOR option in the chapter of the manual external Tables utility.
The first point that applies to your question is that the preprocessor must write its data transformed to stdout. To do this with gunzip, you use the - c command line parameter. The second point that applies to your case, in view of the answer to the first point, is that you must write a script shell if your preprocessor requires command line settings.
Kind regards

Reg: question of external table-
Hi Experts,
I am trying to create and read from an external table, but it raises an error. Please notify.
Scenario-
I'm downloading a file of my APEX application that is stored in a BLOB field. Then, comes the following:
DBMS_LOB.CREATETEMPORARY (v_clob, true);
-/ / Convert BLOB on the CLOB type
() DBMS_LOB.converttoclob
v_clob, v_blob,
DBMS_LOB. LOBMAXSIZE,
v_dest_offset, v_src_offset,
v_blob_csid, v_lang_context, g_msg
);
-/ / creating a csv file
v_temp_filename: = 'apex_ ' | TO_CHAR (sysdate, 'yyyymmddhh24miss') |'. CSV';
-/ / Put the csv file in the database directory 'APEX_DIR '.
dbms_xslprocessor.clob2file (v_clob, 'APEX_DIR', v_temp_filename);
-/ / creating an external table
v_ext_table: = q'[create table (apex_temp_data_ext)

It gives me a generic mistake on the front-end server. But, when I take this external Table as well as the "v_temp_filename", that it is created, but when the SELECTION is fired triggers error:
ORA-29913: error in executing ODCIEXTTABLEOPEN legend
ORA-29400: data cartridge error
KUP-00554: error occurred when parsing the access settings
KUP-01005: syntax error: found 'distinctive sign': expected an a: "binary_double, types binary_float, comma, date, defaultif, char, decimal, double, float, integer, (, nullif, oracle_date, oracle_number, position, raw, recnum,), unsigned, varchar, varraw, varrawc, varcharc, zoned.
KUP-01008: the bad ID was: varchar2
KUP-01007: in column 15 of line 6
Privilege is already provided - GRANT READ, WRITE on APEX_DIR to APEX_DEV;
But you should check with DBA on the rwx for the generated 'v_temp_filename' permission.
Pointers?
Thank you and best regards,
Nordine

External table Oracle via the Tables API
Hello world
I did experiment with the Oracle NoSQL database recently and I became a bit stuck with the new API of Tables. I have so far successfully of the external tables on the data entered using storage techniques 'vanilla' KV and avro (using generic and specific links) scheme, but create API Tables seems to be another matter entirely.
My question arises in the trainer interface, which has a KeyValueVersion and a KVStore. I can't translate a KeyValueVersion created with the API of Tables in a primary key for recovery (since I don't know what the key generated by the API actually looks like to!) or map it on an avro scheme. The problem seems to be that the Tables API writes data in some format that can be easily translated into a string or an integer (releases from external table lines due to unknown characters if I am trying to retrieve all the values in the database to see what it looks like to), and try to map it to an AVRO map results in the error message 'the data are not as AVRO'.
Scenario:
I created a very simple table in the administration tool KV, which consists of a column personId (integer) that is PK, firstName, lastName, emailAddr (all channels) and enter 5 rows with success. What I want to do is to create an external table called person that returns just those 5 values (and brand new I add to the table of course). This means that I have to first understand what the parentKey value must be defined in the .dat file and how to take this key and it becomes a primary key for the recovery of the line.
Faithful old Google could not find information on how to do this (he was only a thread similar to this with the answer "we'll add it soon"), so I hope that someone here managed to do!
Thank you
Richard
Hi Richard
I understand the issue you are facing. In the current version (12.1.3.0.9) the external tables feature only works with records of K/V not with the Table model, however, in the next version (which us will very soon be GA) we will support integration of external tables with the data of Table model as well. Please make sure that you have signed up for the announcement of release so that we can inform you of the release. I apologize for the inconvenience, he did to you.
Best
