Sql 使用select语句并将函数插入游标

可以将with结构与游标中的函数一起使用，我不知道是否声明了不正确的with结构，在过程中使用with函数会出现以下错误pl sql语句不受支持

错误消息清楚地表明您不能执行您要执行的操作，但是如果您的光标如下所示，则不必执行

CURSOR c_detail IS
WITH test_data AS(
    SELECT 36.25 AS FOB_I, 12536.36 AS FOB_TOTAL, 362 AS W FROM dual UNION ALL
    SELECT 15.36 AS FOB_I, 3678.65 AS FOB_TOTAL, 362 AS W FROM dual UNION ALL
    SELECT 878.77 AS FOB_I, 89653.13 AS FOB_TOTAL, 362 AS W FROM dual
)
SELECT TD.FOB_I,
       TD.FOB_TOTAL,
       CASE WHEN TD.FOB_I > 0 AND TD.FOB_TOTAL > 0 AND TD.W > 0 
       THEN (TD.FOB_I * TD.W) / TD.FOB_TOTAL
       ELSE 0
       END WEIGHT
FROM test_data TD
;

[TL；DR]您可以在子查询factoring子句中声明函数，但正如Justin Cave所述，它仅在您以动态SQL的形式执行查询时才起作用，并且在将来的数据库版本中可能会支持在游标内使用静态SQL中的函数

此带有函数的子查询factoring子句在游标外部工作：

具有 带_函数的函数 p_id的编号 返回号码 是 开始 返回42+p_id； 终止 测试单元数据id为

从DUAL CONNECT中逐级选择您使用的Oracle版本是什么？基于此，我相信您需要使用动态SQL才能完成此任务this@M10Oracle 12C感谢大家的帮助，我还以为是我在光标处宣布了一些错误
