> 这个异常是因为对于函数来说`slice`，它注册了`((array(T),bigint,bigint) -> array(T))`，但没有`ARRAY<VARCHAR>, INTEGER, INTEGER`，只有第二个和第三个参数类型不同。 有两种解决方案 > > 1. 将切片从 gluten expressionMap 移动到仅 CH 后端https://github.com/apache/incubator-gluten/blob/main/gluten-core/src/main/scala/org/apache/gluten/expression/ExpressionMappings.scala#L221 > 2. 使用 实现该功能`ARRAY<VARCHAR>, INTEGER, INTEGER`。https [://github.com/facebookincubator/velox/blob/main/velox/functions/prestosql/Slice.cpp#L210](https://github.com/facebookincubator/velox/blob/main/velox/functions/prestosql/Slice.cpp#L210) > > 我更喜欢第二种方法，数据类型的改变非常容易实现 This is not just an issue with slice; similar problems can occur with other array functions when there is a mismatch. -- This is an automated message from the Apache Git Service.
