Max Gekk 5651284c3b [SPARK-32992][SQL] Map Oracle's ROWID type to StringType in read via JDBC ... ### What changes were proposed in this pull request? Convert the `ROWID` type in the Oracle JDBC dialect to Catalyst's `StringType`. The doc for Oracle 19c says explicitly that the type must be string: https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/Data-Types.html#GUID-AEF1FE4C-2DE5-4BE7-BB53-83AD8F1E34EF ### Why are the changes needed? To avoid the exception showed in https://stackoverflow.com/questions/52244492/spark-jdbc-dataframereader-fails-to-read-oracle-table-with-datatype-as-rowid ### Does this PR introduce _any_ user-facing change? Yes ### How was this patch tested? N/A Closes #29884 from MaxGekk/jdbc-oracle-rowid-string.
