这个 SQL 语句中使用了 SEQ_KD_INDEX.nextval,而在 SELECT 语句中不能直接使用序列的 nextval() 方法,因为 nextval() 方法不是一个常量或字面值,而是一个函数,因此不能在字符串中直接使用。要解决这个问题,可以将 nextval() 放在一个子查询中,然后在 SELECT 语句中引用该子查询的结果。例如,可以将第一个 SELECT 语句修改如下:
```
SELECT '155427848241370' || (SELECT SEQ_KD_INDEX.nextval FROM dual) || 'GJ', a.PROBABLECAUSE, ...
```
这样就可以在字符串中引用 nextval() 方法的返回值了。注意,这里使用了 Oracle 中的 dual 表来执行子查询,因为在 Oracle 中,必须使用 FROM 子句来指定一个表,即使这个表只包含一行数据也是如此。
