    Oracle 8.1.7 Unions with differing datatypes in the selects

    We are migrating a SQL Server 2000 view to Oracle 8.1.7. There is one
    view which uses a Union statement, which in the first select, the 8th
    column is selecting a varchar2, and in the second select the 8th col
    is a CLOB.

    Has anyone written their own TO_CHAR function that will take a CLOB
    and convert it, as the Oracle provided functions do not work correctly
    on this version. They work OK in 9.

    Cheers
