SQL input is treated as multiple statements only when the CLIENT_MULTI_STATEMENTS setting is enabled on the client side, enhancing compatibility with MySQL. #36759

New features

  • A new BE configuration allow_zero_date has been added, allowing dates with all zeros. When set to false, 0000-00-00 is parsed as NULL, and when set to true, it is parsed as 0000-01-01. The default value is false to maintain consistency with previous behavior. #34961
