Hi
I am loading data into table using sqlldr(SQL Loader).
how can i prevent data to append/insert into table if any row in the data file/csv file is bad or empty, or mismatch datatype etc.
when i try with bad data file it is still enter good data into table, but in my case i dont want even the good row to be inserted in the table if any row is bad.if any row is bad it should exit without inserting data.
pls let me know.
Thanks
sami

Either use direct option as shown
or
load to a staging table.
If you are not happy with the loaded data, dump the data in staging table.
If you are happy with the load then, insert data from staging table into your target table.
Please see session.

Thank you Mahesh,
when i tried using the option Direct, i am getting error, but if try without direct option it is inserting good data.
pls see the following.
[oracle@dl1 java]$ sqlldr control=test.cntl direct=y errors=0

Hi Mahesh,
Can i give NOT NULL in the control file, because we are creating table which accepts the null values, but i dont have to insert data into table if the file column has any null values,
pls see my control file
test.cntl:
load data
infile '/home/oracle/java/test.csv'
append into table pub.table_test
fields terminated by ","
optionally enclosed by '"'
(custno not null,
loginid ,
permission ,
delivery )
Thanks in advance
Sami

I think i have to use WHEN clause in the control file
eg: test.cntl
load data
infile '/home/oracle/test/java/test.csv'
append into table pub.sami_test
WHEN custno != ' ' <========== here we have to use WHEN
fields terminated by ","
optionally enclosed by '"'
(custno ,
loginid ,
permission ,
delivery )
