存储过程和触发器编译但未找到数据错误

Question

我已经成功运行了以下过程和触发器，但是当我运行整个脚本时，我收到了错误消息和代码。请帮助我理解我在这里收到的错误消息。我看到表格上的数据，但它没有抓取？

--ERROR MESSAGE 错误从命令中的第 1,243 行开始：EXECUTE p_update_cust_fuzzy_perform_mv 错误报告：ORA-01403：未找到数据 ORA-01403: 未找到数据 ORA-06512: 在 “FUZZYTEST1.T_CUST_FUZZY_PERFORMANCE_MV”，第 23 行 ORA-04088：错误 在执行触发器“FUZZYTEST1.T_CUST_FUZZY_PERFORMANCE_MV”期间 ORA-06512：在“FUZZYTEST1.P_UPDATE_CUST_FUZZY_PERFORM_MV”，第 30 行 ORA-06512: 在第 1 行 01403. 00000 - “未找到数据”

您所做的就像加入 2 个表，而您的代码中缺少的是这样的 where 子句

where t1.col = t2.col

你也可以像这样使用 join 来做到这一点

select t1.customer_no, t1.lname, t1.fname, sysdate, t2.mem_set, t2.status
FROM 
(SELECT customer_no, lname, fname, sysdate
FROM wt_net) t1
JOIN
(select DISTINCT MEM_SET as mem_set, status
from fuzzy_param_triangle
where status=1) t2
ON t1.col = t2.col;
