"WRONG_NUM_ARGS" : {
"message" : [
- "Invalid number of arguments for the function <functionName>."
+ "The <functionName> requires <expectedNum> parameters but the actual
number is <actualNum>."
Review Comment:
```
"Cannot resolve <sqlExpr> due to data type mismatch:"
```
I think `WRONG_NUM_ARGS` is not a sub-class of `DATATYPE_MISMATCH`, so we
don't need to follow the existing message from `DATATYPE_MISMATCH`.
Maybe
```
"The <functionName> requires <expectedNum> parameters but the actual number
is <actualNum>."
```
alone also can helpful for user to fix the problem ??
WDYT, @cloud-fan @srielau @MaxGekk ?
Do we want to show the `<sqlExpr>` in the error message as well??
