Implementing dynamic table names in MyBatis can be achieved through the use of dynamic SQL. Dynamic SQL is a powerful feature provided by MyBatis that allows for the dynamic generation of SQL statements based on different conditions.<\/p>\n

The specific steps of implementation are as follows:<\/p>\n

    \n
  1. you finish your homework, you can watch TV.<\/li>\n<\/ol>\n
    <select<\/span> id<\/span>=\"selectUser\"<\/span> resultType<\/span>=\"User\"<\/span> parameterType<\/span>=\"map\"<\/span>><\/span>\r\n    SELECT * FROM\r\n    <choose<\/span>><\/span>\r\n        <when<\/span> test<\/span>=\"tableName == 'table1'\"<\/span>><\/span>\r\n            table1\r\n        <\/when<\/span>><\/span>\r\n        <when<\/span> test<\/span>=\"tableName == 'table2'\"<\/span>><\/span>\r\n            table2\r\n        <\/when<\/span>><\/span>\r\n        <otherwise<\/span>><\/span>\r\n            default_table\r\n        <\/otherwise<\/span>><\/span>\r\n    <\/choose<\/span>><\/span>\r\n    WHERE id = #{id}\r\n<\/select<\/span>><\/span>\r\n<\/code><\/pre>\n
      \n
    1. Passing dynamic table name parameters in Java code, selecting table names to query based on conditions.<\/li>\n<\/ol>\n
      Map<String, Object> params = new<\/span> HashMap<\/span><>();\r\nparams.put(\"tableName\"<\/span>, \"table1\"<\/span>);\r\nparams.put(\"id\"<\/span>, 1<\/span>);\r\nUser<\/span> user<\/span> =<\/span> sqlSession.selectOne(\"selectUser\"<\/span>, params);\r\n<\/code><\/pre>\n
      By following the above steps, it is possible to dynamically pass table name parameters in MyBatis, allowing for the selection of different table names based on conditions for query operations.<\/p>\n","protected":false},"excerpt":{"rendered":"
