Re: Populating VARCHAR2 with LONG data...

The COPY command does not fit the requirements that Harpal stipulated.

And yes, I didn't include that the maximum varchar2 size that can be used is 4k.

It would probably be better to make use of a CLOB.

Hi...
If you do not want to use pl-sql for populating your varchar2 field, then another choice is:

use the COPY command from sqlplus... for doing the pass of data.

you must have into account that varchar2 just can hold up to 4000 characters!

so, your long data column, should not have more than 4000 chars or you could use: set long 4000
