StructType.toString throws UnsupportedOperationException

[ibzib]

Doing String.format or any other function that calls toString fails on a struct type.

Our solution to the problem was overriding this class on the classpath with the version that has an implementation.

[ibzib]

Which version has an implementation?

[kanterov]

There nothing publicly available that I'm aware of, but such version could look like:

public class ZetaSQLStrings {
...
  public static String toIdentifierLiteral(String str) {
    return str; // TODO escape if needed
  }
...
}
