    you cannot use comparisons like
    if clob_column_1 = clob_column_2
    use dbms_lob.compare

    begin
    if inserting then
    INSERT INTO tblworkingcontentversion (idworkingcontentversion,content,IdWorkingContent,IdUser,MinorVersion, idDocument) values
    (sq_tblwcontvers.nextval,:new.content,:new.idworkingcontent,:new.iduserwhocreate,1,:new.iddocument);
    end if;
    if UPDATING then
    if dbms_lob.compare(:new.content,ld.content,30000,1,1)<>0 then
    INSERT INTO tblworkingcontentversion (idworkingcontentversion,Content,IdWorkingContent,IdUser, idDocument) values
    (sq_tblwcontvers.nextval,:new.content,ld.idworkingcontent,ld.iduserwhocreate,ld.iddocument);
    end if;
    end if;
    end;


    It doesn't work.
    Please if u can write some code it would help so much.
    I want a trigger that triggers when only the content (clob field)
    updates and I am not managing to do that.
