Just seeing if anyone has come across this before.
When I create the external table the NUMBER column of the table has random numbers that are not in the file being converted. As you can see, the ID value is at the end of the record along with an CRLF.
So, I'm guessing the conversion of ID is also adding in the actual ID number plus the CRLF and that's why the ID column is not the number in the file.
The file can't be changed so how do I work around this and get the actual ID value that is in the file?
CREATE TABLE EXTERNAL_TBL
(
FIRST_NAME VARCHAR2(40 CHAR),
LAST_NAME VARCHAR2(40 CHAR),
DEPARTMENT VARCHAR2(60 CHAR),
ID NUMBER
)
ORGANIZATION EXTERNAL
( TYPE ORACLE_LOADER
DEFAULT DIRECTORY TEMP
ACCESS PARAMETERS
(
records delimited by newline
skip 1
fields terminated by ','
optionally enclosed by '"'
missing field values are null
(first_name char(40),
last_name char(40),
department char(40),
id integer)
)
LOCATION (TEMP:'duane-excel-example-2.csv')
)
REJECT LIMIT 0;
The file shows the ID column has a value of 123456
The Table shows the ID column has a value of 875770417

What I meant was that the ID field is at end of the table definition and then the CRLF follows that in the file.
(first_name char(40),
last_name char(40),
department char(40),
id integer)
It appears the fix is to change the Integer to be Char and add RTRIM to the field.
(first_name char(40),
last_name char(40),
department char(40),
id char(20) rtrim)

Then I don't.
Here's some data.
CREATE TABLE EXTERNAL_TBL
(
FIRST_NAME VARCHAR2(40 CHAR),
LAST_NAME VARCHAR2(40 CHAR),
DEPARTMENT VARCHAR2(60 CHAR),
ID NUMBER
)
ORGANIZATION EXTERNAL
( TYPE ORACLE_LOADER
DEFAULT DIRECTORY TEMP
ACCESS PARAMETERS
(
records delimited by newline
skip 1
fields terminated by ','
optionally enclosed by '"'
missing field values are null
(first_name char(40),
last_name char(40),
department char(40),
id integer)
)
LOCATION (TEMP:'excel-example-1.csv')
)
REJECT LIMIT 0;
Viewing the attached file in Notepad++ will show the CRLF at the end of each record.

Thank you.
Very interesting. My last employment was a Windows shop so I never saw this behavior before. Now with a different place that runs Unix and I can see how things need to change based on the platform.
I did try different combinations of "records delimited by" but I can see by your example that my syntax was way off.
Thanks again.

Well.....I tried your code and it doesn't work on Unix.
CREATE TABLE EXTERNAL_TBL
(
FIRST_NAME VARCHAR2(40 CHAR),
LAST_NAME VARCHAR2(40 CHAR),
DEPARTMENT VARCHAR2(60 CHAR),
ID NUMBER
)
ORGANIZATION EXTERNAL
( TYPE ORACLE_LOADER
DEFAULT DIRECTORY TEMP
ACCESS PARAMETERS
(
records delimited by X'0D0A'
skip 1
fields terminated by ','
optionally enclosed by '"'
missing field values are null
(first_name char(40),
last_name char(40),
department char(40),
id integer EXTERNAL(10))
)
LOCATION (TEMP:'duane-excel-example-2.csv')
)
REJECT LIMIT 0;

It's a challenge sometimes when you can't show production data so I was just using data I made up. I just went longer on the ID when entering that data into the spreadsheet. I didn't think about it when you showed me the "integer external(x)" reference and my ID data was longer than actual production data. After I posted my reply, it dawned on me that production data only had a length of 8.
Thanks again.
