PLS-00497: cannot mix between single row and multi-row (BULK) in INTO list Cause: - When BULK syntax (e.g. BULK COLLECT INTO) is used to retrieve data, every variable in the INTO list has to be of type that is a collection of the type of the corresponding column. - When BULK is NOT used, every variable in the INTO list has to be of compatible type with the corresponding column. Action: Change the INTO list so that all variables have correct data types 需明确定义列 如：type col1 is table of iptpa_poll_host.col1%type; v_d  col1 ; fetch v_c bulk collect into v_d 此时，取了一个列的集合
