【问题描述】:
请帮助我理解为什么第二个块抛出错误但第一个块正在运行。两个地方的限制都小于声明的大小(41)。
Declare
Type typ_int_array IS VARRAY(41) OF NUMBER;
v_typ_int_array typ_int_array := typ_int_array(10,20,30,40);
BEGIN
SYS.DBMS_OUTPUT.PUT_LINE(v_typ_int_array(1));
v_typ_int_array.extend(6);
v_typ_int_array(6) := 60;
END;
Declare
Type typ_int_array IS VARRAY(41) OF NUMBER;
v_typ_int_array typ_int_array := typ_int_array(10,20,30,40);
BEGIN
SYS.DBMS_OUTPUT.PUT_LINE(v_typ_int_array(1));
v_typ_int_array.extend(38);
v_typ_int_array(38) := 60;
END;
例外:
**Error :**
Error report -
ORA-06532: Subscript outside of limit
ORA-06512: at line 6
06532. 00000 - "Subscript outside of limit"
*Cause: A subscript was greater than the limit of a varray
or non-positive for a varray or nested table.
*Action: Check the program logic and increase the varray limit
if necessary.
