1. How to Install
>loadjava -v -u user/pass@[TNSNAME] -r dbf2csv.jar
>sqlplus user/pass@[TNSNAME] @dbf2csv.sql
2. How to Run
>sqlplus user/pass@[TNSNAME]
sql>
set serverout on
declare
Path varchar2(1000) := '/temp/'; -- directory with perms
DFBFile varchar2(1000) := 'DFBFile.dbf';
CSVFile varchar2(1000) := 'CSVFile.csv';
Fine varchar2(1000);
begin
Fine :=
nn$dbf2csv.dbf2csv(Path||DFBFile, Path||CSVFile, ';');
dbms_output.put_line(substr(Fine,1,255));
end;
/
File -/temp/'CSVFile.csv will be created
Warning! Grant Oracle Java permissions to USER.
> sqlplus "sys/[password]@[TNSNAME] as sysdba"
sql>
begin
dbms_java.grant_permission('USER',
'SYS:java.io.FilePermission',
'/temp/-',
'read,write,delete');
end;
CREATE OR REPLACE DIRECTORY temp AS '/temp/';
GRANT READ ON DIRECTORY temp TO user;
GRANT WRITE ON DIRECTORY temp TO user;
GRANT DELETE ON DIRECTORY temp TO user;
/

3. Now you can upload data from .csv file to an Oracle Database

>sqlplus user/pass@[TNSNAME]
sql>
declare
Path varchar2(1000) := '/temp/'; -- directory with perms
DFBFile varchar2(1000) := 'DFBFile.dbf';
CSVFile varchar2(1000) := 'CSVFile.csv';
Fine varchar2(1000);
begin
Fine :=
nn$dbf2csv.dbf2csv(Path||DFBFile, Path||CSVFile, ';');
execute immediate Fine;
end;
4. Now you can fetch data from Oracle external table created based on Excel file

>sqlplus user/pass@[TNSNAME]
sql> select * from NNDBF$DFBFile;
