   I think you forget to register this function in FE's FunctionSet. You can add it in gensrc/script/doris_builtin_functions.py just like function round.
   
   Btw, you'd better to add a SQL-like regression test case in folder regression/suites

+## round_bankers
+
+### description
+#### Syntax
+
+`round_bankers(x), round_bankers(x, d)`
+Rounds the argument `x` to `d` specified decimal places. `d` defaults to 0 if not specified. If d is negative, the left d digits of the decimal point are 0. If x or d is null, null is returned.
+
++ If the rounding number is halfway between two numbers, the function uses banker’s rounding.
++ In other cases, the function rounds numbers to the nearest integer.
+
+
+
+### example
+
+```
+mysql> select round_bankers(0.4);
++--------------------+
+| round_bankers(0.4) |
++--------------------+
+|                  0 |

   That's right!! I did trace the code and found that `getBuiltinFunction` returned `nil`, so it was registered through here, thank you very much! And I will complete the test cases as soon as possible
