Change subject: IMPALA-15202: Add explicit CAST support between UUID and STRING ...................................................................... Patch Set 2: (1 comment) http://gerrit.cloudera.org:8080/#/c/24817/2/testdata/workloads/functional-query/queries/QueryTest/iceberg-uuid-type.test File testdata/workloads/functional-query/queries/QueryTest/iceberg-uuid-type.test: http://gerrit.cloudera.org:8080/#/c/24817/2/testdata/workloads/functional-query/queries/QueryTest/iceberg-uuid-type.test@475 PS2, Line 475: CAST(uuid_col AS CHAR(36)) > What happens for CAST(uuid_col AS CHAR(30)), or CAST(uuid_col AS CHAR(40))? Nice observation. Tried this out and since UUID is cast to CHAR in two steps, first it produces the canonical 36-character form and then CastToChar truncates or right-pads with spaces. -- To view, visit http://gerrit.cloudera.org:8080/24817 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I51af55c6e343f7155cae22bf3714e293f31561d5 Gerrit-Change-Number: 24817 Gerrit-PatchSet: 2 Gerrit-Owner: Arnab Karmakar <[email protected]> Gerrit-Reviewer: Arnab Karmakar <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Zoltan Borok-Nagy <[email protected]> Gerrit-Comment-Date: Wed, 16 Sep 2026 15:37:23 +0000 Gerrit-HasComments: Yes
