Answer 1

LONG datatypes cannot be used for Insert with selects or CTAS.
If the maximum length of the long datatype column is less than or equal to 4000 then you can use
SQL> insert into temp select col1, col2, dbms_metadata_util.long2varchar(4000,'TABLE_NAME','COLUMN_NAME',rowid) Column_alias from temp1;
If the maximum length of the long column is greater than 4000 then you can use
SQL> insert into temp select col1, dbms_metadata_util.long2clob(40000,TABLE_NAME','COLUMN_NAME',rowid) Column_alias from temp1;
