> I try reading a database model, which contains a table with LONG VARCHAR columns in it.
As described in the documentation, the write-back of the unchanged model to Oracle results
in a ColumnDataTypeChange (to CLOB).
> When the change is to be applied to the DB, there is no cast from LONG VARCHAR to LOB.
Say I have a table
> CREATE TABLE T (
>   DATA LONG VARCHAR
> );
> the script, which is generated by ddlutils is
> CREATE TABLE T_ (
>   DATA CLOB
> );
> INSERT INTO T_ (DATA) SELECT DATA FROM T;
> [...]
> At this point Oracle exits with ORA-00997: Unzulässige Verwendung des Datentyps LONG
> IMHO the script should have been
> INSERT INTO T_ (DATA) SELECT TO_LOB(DATA) FROM T;
> which works fine.
