SQL & PL/SQL :: External Table And Blank Strings

Sep 23, 2011

I am importing some data using an external table, but the file on which the external table is built has some rows where a certain column is populated with two empty space characters.

CREATE OR REPLACE DIRECTORY xtern_data_dir AS 'C:/...';

CREATE TABLE ET_RPDMMA1_PEDI_MSTR (
GCN_SEQNO NUMBER(6),
PDM_MNAGE NUMBER(4),
PDM_MXAGE NUMBER(4),
PDM_MND NUMBER(18,6),
[code].......

This is an except of what's in the external text file. The full text file has been attached.

000011|0030|....|000000.000000| |000000.000000| |0002
000011|0365|....|000000.000000| |000000.000000| |0002
000011|0730|....|000000.000000| |000000.000000| |0002
^
blank spaces may be |
causing error----------

Here is the error message I am receiving. I believe this is caused by the blank fields in the data.

INSERT INTO RPDMMA1_PEDI_MSTR (GCN_SEQNO,....
*
ERROR at line 1:
ORA-29913: error in executing ODCIEXTTABLEFETCH callout
ORA-30653: reject limit reached
ORA-06512: at "SYS.ORACLE_LOADER", line 52

This is difficult to work with because the external table function does not appear to be even reading the file so it's not like I can convert the data as I'm loading into the internal database table. What are some approaches I can use to get Oracle to accept these blank columns and either populate them with blank spaces or set them to null?

SQL & PL/SQL :: External Table Query (compare Number Records In File With External Table)

Jan 23, 2013

I have got a procedure that successfully creates an oracle external table and populates it with the contents of a file. This works fine until I have a situation where one of the fields is a VARCHAR2(2) and I try to insert say, a 5 character value. When this happens the record in question does not get populated in the external table (and rightly so), but I could do with working out if there is a discrepancy in the number of records in the file and the number of records that actually make it into the table so I could inform the user that there is a problem.

I have attached the code that creates the external table and populates it.

SQL & PL/SQL :: Updating Another Table For Equal Strings

Jun 8, 2010

There are two tables:

create table songs(song_name text, song_artist text,song_url text, song_cat text, last_edit text);
create table categories(cat_name text, cat_total int);

im trying to create a trigger that, when i insert a new song in the songs table, it will check the category of the song (song_cat) and increase the respective cat_total (from table categories) by 1.

here is what i've done so far:

drop trigger countcat;
CREATE TRIGGER countcat AFTER INSERT ON songs FOR EACH ROW
update categories SET cat_total= cat_total +1
WHERE cat_name = (select song_cat FROM inserted);

What to write in the cat_name = (select ...). I have tried lots of stuff but still nothing. when i use this, i get the error that mydatabase.inserted doesnt exist

Precompilers, OCI & OCCI :: How To Pass Array Of Strings To And Return Table Set From Proc

Jan 24, 2011

I have to write a PL/SQL procedure, which is supposed to take an array of strings as input. This array will have simple strings as elements, like

'000887S','000780S'.

Now I have a query in the procedure, which will return a row, for each of the array elements. For example:

SELECT
su.EMPLOYEE_ID,su.FIRST_NAME,
su.LAST_NAME
FROM
USERS su,
[code]......

In the place of the '?' in the above query, the array elements have to be passed. So we will get one row from the above query for each array element.

Now we either have to loop through the array elements to fetch the result set for the above query for each array element, or we can use some other method too. Our objective is to collect all the rows of the above query for each array element as a table data and this procedure has to return this table set.

what will be the best way to pass such a set of data to the proc and best way for the proc to return this result set. Like we can use arrays, table type data,ref cursors, etc.

SQL & PL/SQL :: Insert All Records From External Table Into Export Table

Mar 25, 2013

following is the requirement

External Table
WKSHT_FILE_EXT
wksht_line
Export Table
Wksht_export
global_idvarchar2(10)
wksht_linevarchar2(250)
[code]....

Step 1.Insert all records from the external table into the export table. Truncate the export table first

Step 2.Read in a record from the export map table

Step 3.Search through export table records looking for the key words BRANCH =. Compare the branch code with the branch code form the map table

Step 4.If a match is found mark all records in the export table for the worksheet with the global ID from the export map table as follows..The first line of a worksheet is marked by the words WKSHTS..The last line of the work sheet is marked by the words COMPANY CONFIDENTIAL..We will need to capture the line break so also mark the next line after the COMPANY CONFIDENTIAL line

Step 5.Continue with Steps 2 - 4 until all records have been processed from the export map table.

first I have to create a procedure ti insert data from external table to export table.Global id will be blank.it will be updated by the mapping table's Global Id when The EB COLUMN's data(i.e 8p,2Betc ) will match with the BRANC=NA,2Betc of the datasheet loaded from the external table.. FOLLOWING IS THE SAMPLE DATASHEET

WKSHTS AAAAA BBBBBBBBBBB ELECTRONICS INC. TIME REPORT-DATE PAGE
SORT - BR, SLSREP AEC FIELD SALES REPRESENTATIVE 16:14 09/21/12 1
BRANCH = 2B
EMPLOYEE NAME SALVAAG, GREGG Days in the Month 28
[code]....

THERE ARE 2 pages..I have to split this LONG REPORT STORED IN WKSHT_LINE COLUMN OF EXPORT TABLE to 2 records..like wise 500 pages are there means 500 records.. AND THEN FIND BRANCH= after that which two words will come i.e NA,2B etc if it will MATCH WITH MAPPING TABLE"S EB COLUMN"S DATA,THEN MAPPING TABLE's GLOBAL ID WILL BE UPDATED TO EXPORT TABLE's GLOBAL ID WHICH IS BLANK

MS Excel As External Table

Sep 6, 2013

I need to do some analysis and research to find if any of these 8000 tables I have in a spreadheet that are going to be spit off into a separate database are used by any of our PeopleSoft processes.

I'm assigned to Student Records identified by NTSR.

So for table AAP_ETHNIC_PMPT, I could do something like

SELECT *
FROM PSSQLTEXTDEFN
where SQLID like 'NTSR%'
AND upper(sqltext) like '%PS_AAP_ETHNIC_PMPT%';

But how can I automate this and search 8000 rows in column A2 of a spreadsheet? What other tables other than PSSQLTEXTDEFN or PSPROJECTITEM can I use to search for values of NTSR?

SQL & PL/SQL :: External Table With Validation

Jun 25, 2010

I'm trying to create a external table column validation.

I have data like this

First column is Numeric, second is Non-Numeric

1,X
2,Y
3,Z

There are chances that I may have data as following
1,X
2A,Y
3,Z

My requirement is whenever I get non-numeric data in first column I want to pass 0 or NULL. So, I have created a external table with following script.

CREATE TABLE EXT_test
(
SL NUMBER (4),
BRANCH_NAME VARCHAR2 (100)
)
ORGANIZATION EXTERNAL
(
[code]........

Following is the code for function is numeric

function isnumeric( p_string in varchar2) return boolean as
l_number number;
begin
l_number := p_string;
return TRUE;
exception
when others then
return FALSE;
end;

It is not recognizing function IS NUMERIC. Is there any way, I can do this through External Table.

I'm getting error like

The following error has occurred:

ORA-29913: error in executing ODCIEXTTABLEOPEN callout

SQL & PL/SQL :: External Table And Spanish Characters

Sep 27, 2011

I am having difficulty importing Spanish text files into my Oracle 11g XE database. Below is my external table declaration code. The external file is attached.

CREATE OR REPLACE DIRECTORY xtern_data_dir AS 'C:/.../';

CREATE TABLE ET_SLBLWD0_SPNSH_DESC (
LBL_WARN VARCHAR(4),
LBL_TXTSNS NUMBER(2),
LBL_DESCS VARCHAR2(55),

[Code]...

All 406 rows seem to import fine, but do not display the Spanish accent characters correctly. Note the strange characters:

SQL> SELECT count(*) FROM ET_SLBLWD0_SPNSH_DESC;

COUNT(*)
----------
406

SQL> select * from et_slblwd0_spnsh_desc;

LBL_ LBL_TXTSNS LBL_DESCS L L L L
---- ---------- ------------------------------------------------------- - - - -
0001 1 Puede causar somnolencia. El alcohol puede intensificar
0001 2 este efecto. Tenga cuidado cuando conduzca veh¿los
0001 3 automotores u opere maquinaria peligrosa.
0002 1 Importante: Acabe todo este medicamento a menos que
0002 2 quien le escriba la receta le indique lo contrario.

[Code]...

I tried modifying my external table declaration by adding CHARACTERSET WE8ISO8859P1 and CHARACTERSET WE8MSWIN1252, but that just seems to cause the system to throw out ALL the rows containing Spanish characters:

COUNT(*) ---------- 197

SQL> select * from et_slblwd0_spnsh_desc;

LBL_ LBL_TXTSNS LBL_DESCS L L L L
---- ---------- ------------------------------------------------------- - - - -
0001 1 Puede causar somnolencia. El alcohol puede intensificar
0001 3 automotores u opere maquinaria peligrosa.
0002 1 Importante: Acabe todo este medicamento a menos que
0002 2 quien le escriba la receta le indique lo contrario.
0005 1 Debe tomar este medicamento con mucha agua.
0006 1 Puede descolorar la orina o las heces.

[Code]...

The log file specifies the following error on the bad rows:

error processing column LBL_DESCS in row xxx for datafile ...SLBLWD0_CRLF.TXT ORA-12899: value too large for column LBL_DESCS (actual: 55, maximum: 55)

What can I do to import these Spanish characters correctly?

Server Utilities :: How To Create External Table

Aug 10, 2012

im trying to create an external table, and i load my data without no problem, and everything is fine, but i got some behavior with one column that i would like to know whats behind scenes, OK let's get the example:

[*] Sample Data
Line 1:333 1111111112009100000000000080000000013450.33
Line 2:11111111111220091016000000004.48
Line 3:222222222 220091016000000004.48
Line 4:(This is a blank line left)

And this is my External Table Create Query:

CREATE TABLE EXT_TABLE_TEMP
(COL_A VARCHAR2(11),
COL_B VARCHAR2(1),
COL_C DATE,
COL_D NUMBER(12,2))
ORGANIZATION EXTERNAL

[code]....

As you can see i can upload my table with no problem but i always get 3 lines counting last blank line if i try LOAD WHEN COL_A != BLANKS, i dont know if its a problem of the blank space left between fixed fields length, but if i do LOAD WHEN COL_B != BLANKS i get correct result 2 lines instead of 3, i want to know why (missing fields...) and (reject rows...) are not working...

Note: COL_A could be 9-11 length, if length its 9 then 2 spaces left before next one...

Can I create an external table for loading this file based on selection of fields driven by the record identifier which is the first field of each record, except for the firt two?

For e.g In the above file, for records which say 'abc' in it's first field, I want to load the 2,3,6,8 fields delimited by a comma (the values may as well be null in those fields) and for records which say 'Product' in their first fields, I want to load 5,8,9 and 10 fields from the same file. Basically, I want to know if we can use instr function while choosing the fields line by line based on a search criteria in the file. There will be less columns in my table than the number of fields in the csv file, so I guess I got to mention 'MISSING FIELD VALUES ARE NULL' option. There is another challenge too - I have to skip loading the first two lines from the file to the table.

I have written a big pl/sql proc for doing the same, using utl_file.get_line option, but it is still untested and I would be extremely happy to believe that this can be achieved by creating an external table too.
