Details

    • Can result in data loss
    • Q3/2026 Server Maintenance

    Description

      e.g.

      --mkdir $MYSQL_TMP_DIR/o'hara
      		 
      eval create table t1 (a int) data directory="$MYSQL_TMP_DIR/o'hara";
      		 
      show create table t1;
      		 
      drop table t1;

      this prints

      CREATE TABLE `t1` (
      		 
        `a` int(11) DEFAULT NULL
      		 
      ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_swedish_ci DATA DIRECTORY='MYSQL_TMP_DIR/o'hara/'
