    curfroeign cursor (columnname varchar(300)) is select
distinct(fk_relation),fk_column from foreign_keys
where pk_relation in (select pk_relation from
foreign_keys where pk_column=columnname);
        var_str1  varchar(300);

BEGIN


    open curforeign(par_colname);

||tablename || 'where' ||columnname||'='||parcolvalue;
