Review comment:
I just checked it roughly, and looks like temporary view is not loaded
by `loadTable` - it throws NoSuchTableException in V2SessionCatalog.
```
test("write to temporary view shouldn't be allowed") {
val tableIdentifier = "table_name"
val tempViewIdentifier = "temp_view"
spark.sql(s"CREATE TABLE $tableIdentifier (id bigint, data string) USING
parquet")
checkAnswer(spark.table(tableIdentifier), Seq.empty)
spark.sql(s"SELECT id, data FROM
$tableIdentifier").createOrReplaceTempView(tempViewIdentifier)
// spark.sql(s"CREATE TEMPORARY VIEW $tempViewIdentifier AS SELECT id,
data FROM $tableIdentifier")
withTempDir { checkpointDir =>
val exc = intercept[AnalysisException] {
runStreamQueryAppendMode("default." + tempViewIdentifier,
checkpointDir, Seq.empty, Seq.empty)
}
assert(exc.getMessage.contains("doesn't support streaming write"))
}
}
```
fails with `"Table default.temp_view not found;" did not contain "doesn't
support streaming write"`
