RE: Transferring data from one table to anotherSQL*Plus COPY command can do it, truncating the contents of the LONG after the length specified by by SET LONG command...





  How about if your table has (I didn't do it) a LONG column. CTAS doesn't work and I don't see the nologging option for the ccopy command - in 8.1.6 anyway.

    CTAS with nologging.  Could create a simple script to do this.
