Ma77Ball opened a new pull request, #58761: URL: https://github.com/apache/spark/pull/58761
### What changes were proposed in this pull request? Rename the legacy error condition `_LEGACY_ERROR_TEMP_1068` to the new named condition `CANNOT_USE_RESERVED_DATABASE_AS_CURRENT` (SQLSTATE `42939`). It is raised when a session sets the current database to the global temporary view database, e.g. `USE global_temp`. ### Why are the changes needed? The error-conditions README disallows new `_LEGACY_ERROR_TEMP_*` entries and asks existing ones to be resolved. This resolves one (part of SPARK-37935). ### Does this PR introduce _any_ user-facing change? Yes. The condition becomes `CANNOT_USE_RESERVED_DATABASE_AS_CURRENT`, and the message is reworded and now quotes the database name with backticks, e.g. ``Cannot use `global_temp` as the current database because the name is reserved for system use. To access global temporary views, use a qualified name, e.g. SELECT * FROM `global_temp`.viewName.`` ### How was this patch tested? Converted the message assertion in `GlobalTempViewSuite` to `checkError`. `SparkThrowableSuite` and `GlobalTempViewSuite` pass. ### Was this patch authored or co-authored using generative AI tooling?
