drtconway opened a new issue, #16327:
URL: https://github.com/apache/datafusion/issues/16327
### Describe the bug
I have a UInt64 column containing a 64-bit hash which I want to convert to a
hex string. `to_hex` should work, but gives the error:
```
Error: Custom { kind: Other, error: Plan("Failed to coerce arguments to
satisfy a call to 'to_hex' function: coercion from [UInt64] to the signature
Uniform(1, [Int64]) failed No function matches the given name and argument
types 'to_hex(UInt64)'. You might need to add explicit type casts.\n\tCandidate
functions:\n\tto_hex(Int64)") }
```
### To Reproduce
Create a DataFrame with a UInt64 column.
Attempt to execute code such as
```rust
df.with_column("my_hash_str", to_hex(col("my_hash")))?;
```
### Expected behavior
We would expect `to_hex` to correctly produce a hex string, especially for
unsigned types!
