Release Note 1.2.3

1.2.4.1

Hot fix version for 1.2.4.

Bug Fixs

• Fix bug that DELETE FROM stmt can not be executed if column name in WHERE clause is upper case([Bug](delete) fix the delete ignore char case #18991)
• Fix bug that using CAST to time may cause BE crash ([branch-1.2](cherry-pick) using typeindex to create column instead of type name because type name is not stable #19004)

1.2.4

Behavior Changed

• For DateV2/DatetimeV2 type, in the results of DESCRIBLE and SHOW CREATE TABLE statements, they will no longer be displayed as DateV2/DatetimeV2, but directly displayed as Date/Datetime.

  • This change is for compatibility with some BI tools. If you want to see the actual type of the column, you can check it with the DESCRIBE ALL statement.

• When querying tables in the information_schema database, the meta information(database, table, column, etc.) in the external catalog is no longer returned by default.

  • This change avoids the problem that the information_schema database cannot be queried due to the connection problem of some external catalog, so as to solve the problem of using some BI tools with Doris. It can be controlled by the FE configuration infodb_support_ext_catalog, and the default value is false, that is, the meta information of external catalog will not be returned.

Improvement

• Supports connecting to Trino/Presto via JDBC Catalog

  • https://doris.apache.org/docs/dev/lakehouse/multi-catalog/jdbc#trino
