ORA-06502: PL/SQL: numeric or value error: character to number conversion error while inserting data through cursor

Question

我有一个简单的 cursor，它获取数据并根据条件将数据插入到 2 table 中。现在对于有效条件，我收到以下错误。请指导我如何检查和匹配条件。

错误如下

ORA-06502: PL/SQL: numeric or value error: character to number conversion error ORA-06512: at "APP_FIBERINV.FIP_VAL_INV_DATA", line 37

下方是光标

create or replace PROCEDURE FIP_VAL_INV_DATA AS

在不知道你的列数据类型的情况下很难猜测真正的错误，但我认为它来自 and l_state_name = 1 标准，因为 l_state_name 必须是一个 varchar 并且当你将它与1，引擎尝试将 l_state_name 转换为数字

用 and l_state_name = '1'

修复

必须与and l_maint_zone_code = 1相同=> and l_maint_zone_code = '1'

顺便把length(cur_r.rj_span_id) = '21'改成length(cur_r.rj_span_id) = 21
