    Description

      When running with sql_mode=ORACLE, MariaDB should emulate Oracle-style transaction related behavior:

      • No explicit transaction start (e.g. BEGIN or START statement) is needed.
        Transactions start automatically and last until COMMIT or ROLLBACK.
        This looks to be equal to SET AUTOCOMMIT=0.
      • The BEGIN keyword should always start a code block (a compound statement), even outside of a stored procedure.

          I assume the an easy solution is that we set autocommit=0 when changing mode to Oracle.

          In 10.2, we already support compound statements with BEGIN NOT ATOMIC.

          The MariaDB syntax, when, running in autocommit=0 mode, is:

          begin not atomic select 1 ; end ; commit |

          While Oracle syntax is:

          begin select 1 ; end ; commit |
