Dear all,

When I import using impdb command & some data exists in the table, then impdb fails. It don't insert remaining records in table. In oracle 9i , we have option ignore=Y , so when we insert duplicate data, it gives error but insert remaining rows. But in case of impdb command, which parameter we have to use so that remaining rows will get inserted.

Thnaks

Thanks. So if I use SKIP option, will it skip entire table or duplicate rows & insert non duplicate rows?

You didn't read properly.

TABLE_EXISTS_ACTION
Default: SKIP (Note that if CONTENT=DATA_ONLY is specified, the default is APPEND, not SKIP.)

Purpose

Tells Import what to do if the table it is trying to create already exists.

Syntax and Description

TABLE_EXISTS_ACTION={SKIP | APPEND | TRUNCATE | REPLACE}

The possible values have the following effects:

SKIP leaves the table as is and moves on to the next object. This is not a valid option if the CONTENT parameter is set to DATA_ONLY.

APPEND loads rows from the source and leaves existing rows unchanged.

TRUNCATE deletes existing rows and then loads rows from the source.

REPLACE drops the existing table and then creates and loads it from the source. This is not a valid option if the CONTENT parameter is set to DATA_ONLY.

Hi,

Thanks for your reply. Actually I want to insert 1 crore records (may contain duplicate data)in table of approx. 100 crore records. I don't want to disable constraint & then then import duplicate rows & then delete duplicate records from entire table. So which is the best method to do this?
