amorynan opened a new pull request, #46927:
URL: https://github.com/apache/doris/pull/46927
### What problem does this PR solve?
if we set session variable for fold_constant_for_be = 1 and
enable_decimal256 = true
here will meet error in sql
```
SELECT ARRAY_AVG(CAST([] AS ARRAY < DECIMALV3(1,0) > ));
```
with core
```
