Hi,

The sql*loader is a utility you load the text,csv data into you oracle database.

The Ex :

emp.ctl (control file)

options(direct= true)
load data
infile 'd:\utl_dir\emp 2.txt'
badfile 'd:\utl_dir\emp .bad'
discardfile 'd:\utl_dir\emp .dsc'
into table emp
fields terminated by "|"
trailing nullcols
(empno,ename.., ...)

from dosprompt : sqlldr scott/tiger control=emp.ctl

It will insert the data from emp2.txt file to oracle emp table.

For exporting the oracle database :

exp userid=system/manager@orcl file=c:\backup. dmp log=c:\backup.l og full=y rows=y owner=scott;

It will export the scott schema objects into backup.dmp file.

For more gothrough the export utility


For Import :

imp userid=system/manager@orcl fromuser=scott touser=scott file=c:\backup. dmp log=c:\backup.l og

It will import the data from backup.dmp to oralce database.

Thanks,
