【案例代码】：
DECLARE
– Local variables here
TYPE T_A IS RECORD(
filed1 VARCHAR2(10),
filed2 VARCHAR2(10),
);
TYPE T_B IS TABLE OF T_A INDEX BY BINARY_INTEGER;
TYPE T_C IS RECORD(
filed4 T_B
);
BEGIN
dbms_output.put_line(‘Hello World!’);
END;
【匿名块窗口错误信息】：执行 SQL 失败，错误详情：Debuggee session is not alive before debugger start
【问题描述】：filed4字段类型定义为集合（TYPE T_B IS TABLE OF T_A INDEX BY BINARY_INTEGER;）时可复现此错误，定义filed4为T_A 时不报错。
