| 其中，IvyexecPreparedStatement2 更为特殊：它要求用户额外提供一个 IvyBindOutInfo* 类型的输出绑定列表。该列表不仅用于绑定 OUT 参数，还被 IvyAssignPLISQLOutParameter 在获取 PL/SQL 过程返回结果时用来识别每个 OUT 参数的数据类型。因此，在处理 CALL语句时，接口会先对用户传入的 IvyBindOutInfo*列表进行位置重排（将INTO对应的输出变量移至首位），再将其写入IvyPreparedStatement语句句柄中，供后续赋值使用。 | ||

| 关于输出参数的精度处理：当CALL语句中的输出绑定变量与实际返回值的精度不匹配时，系统可能报错，也可能自动截断——具体行为取决于绑定变量的数据类型是否与过程/函数声明的参数类型完全一致。 | ||
| 在PL/SQL inline handler中，每个OUT参数的精确数据类型均可通过ParamListInfo在绑定阶段获取。如果当前执行的匿名块是由CALL语句转换而来的特殊DoStmt，那么在执行赋值时，系统会进行如下判断： |
