Mybatis如何运行sql“ desc表”

Question

我对如何运行sql“ desc table”以获取表字段信息有疑问。我尝试运行这些代码以获取表字段信息，但出现语法错误。@Mapperpublic interface TableMapper {/** * 获取指定表中字段的具体信息 * @param tableName 表名 * @return 所有字段的具体信息. */@Select("desc #{tableName}")@Results({        @Result(property = "fieldName", column = "Field", javaType = String.class),        @Result(property = "fieldType", column = "Type", javaType = String.class),        @Result(property = "nullable", column = "Null", javaType = String.class),        @Result(property = "key", column = "Key", javaType = String.class),        @Result(property = "extra", column = "Extra", javaType = String.class)})Set<TableFieldInfo> findTableFieldsInfo(@Param(value = "tableName") String tableName);}有人可以告诉我如何使用mybaits获取表字段信息吗？
