文档解释

ORA-29255: Cursor contains both bind and define arrays which is not permissible

Cause: Both define_array and bind_array have been called on this cursor. This is illegal. It is not possible for a cursor to both contain array binds and array defines. The semantics of this setting are nonsensical. Array defines are used to move data from select queries into PL/SQL tables and array binds to bind PL/SQL tables to non-select queries.

Action: Modify your PL/SQL program to only perform calls to one of the two functions depending on the kind of cursor at hand.

ORA-29255: Cursor包含了既有bind array（变量赋值）又有define array（存储结果集），这是不允许的。官方解释是：无法同时使用bind array和define array，因为PL/SQL不允许同时变量赋值和存储结果集。

常见案例是使用bind array和define array时会引发这个错误，有时错误原因是我们忘记给bind array和define数组赋值。

一般处理方法及步骤

1. 检查代码，是否忘记给bind array和define array赋值？

2. 检查bind array和define数组的大小，以及数据类型是否一致？

3. 检查数组的结构，看看是否正确的构建成数组结构？

4. 将bind array和define array分开，避免同时使用。
