从MySQL 8.0开始，唯一索引的行为得到了改进，以符合SQL标准。在MySQL 8.0及更高版本中，唯一索引只允许一个`NULL`值。这意味着，如果列中已经包含了一个`NULL`值，后续尝试插入另一个`NULL`值的操作将会被拒绝，因为唯一索引要求`NULL`值也是唯一的。

+# MiniOB 向量数据库
+
+## 向量搜索
+
+向量搜索技术是非结构化数据检索的关键技术之一，通常通过近似最近邻搜索（Approximate Nearest Neighbor Search, ANN）的方式来在高维空间中进行检索，以此来找到满足要求的数据。向量搜索在检索相似的图片、音频和文本等方面发挥着关键作用。例如，在图像检索中，我们可以通过计算图像的特征向量，然后使用向量检索技术来找到与查询图像最相似的图像；在推荐系统中，我们可以通过计算用户和物品的特征向量，然后使用向量检索技术来找到与用户兴趣最相似的其他用户或物品。下面针对向量搜索技术的基本概念进行简要介绍。
+
+### 向量（Vector）是什么
+
+向量是一种表示多维特征的数据结构。每个向量由一组数值组成，这些数值通常对应于某种特定的特征或属性。例如，在图像处理中，一个向量可以表示图像的颜色、纹理等特征。为了更有效地管理非结构化数据，常见的做法是将其转换为向量表示，并存储在向量数据库中，这种转换过程通常被称为 Embedding。通过将文本、图像或其他非结构化数据映射到高维向量空间，我们可以捕捉数据的语义特征和潜在关系。单词、短语或整个文档以及图像、音频和其他类型的数据都可以表示成向量，例如，我们可以将下面的文本表示成向量：
+```
+"West Highland White Terrier": [0.0296700,0.0231020,0.0166550,0.0642470,-0.0110980, ... ,0.0253750]
+```
+
+### 向量数据库是什么
+
+向量数据库是可以高效存储/检索向量的数据库。向量数据库用专门的数据结构和算法来处理向量之间的相似性计算和查询。通过构建索引结构，向量数据库可以快速找到最相似的向量。
+
+### 向量搜索的应用
+
+向量在检索相似的图片、音频和文本等方面发挥着关键作用，这源于其数据属性和特征表示能力。在机器学习和数据科学领域，向量被广泛用于描述数据特征。以图片数据为例，我们可以将其表示为向量。在计算机中，图片本质上是由像素构成的二维矩阵。每个像素的亮度值可视为图片的一个特征，因此，我们可以将这些亮度值串联成一个高维向量，从而实现图片的向量化表示。这种向量化表示使我们能够利用向量空间中的距离和相似度度量方法来比较不同图片之间的相似程度。例如，欧氏距离可用于衡量两个图片向量间的像素差异，而余弦相似度则可测量它们的方向差异。通过计算向量间的距离或相似度，我们可以量化评估不同图片之间的相似程度。
+
+除此之外，检索增强生成（Retrieval-Augmented Generation）已经成为大语言模型应用的范式之一。而向量数据库是 RAG 应用中重要组成部分，向量数据库的存储容量、召回精度和召回速度在很大程度上影响了大语言模型应用的服务质量。
+
+## MiniOB 向量数据库赛题
+
+本次赛题，需要选手在 MiniOB 的基础上实现向量数据库的基本功能，向量数据库的功能被拆解为如下几个题目。
+
+### 题目一：向量类型基础功能
+* 向量类型
+  * 语法：`vector(size)`，其中，size 表示向量的维度（必须指定）
+  * 最大支持维度为 16000（在基础功能中只需要支持最大 1000 维向量即可）
+  * 向量类型中的浮点数最多保留两位小数，并且去掉多余的0
+* 支持创建包含向量类型的表：
+```sql
+CREATE TABLE items (id int, embedding vector(3));
+```
+* 支持插入向量类型的记录（注意：这里需要支持将字符串类型的值转换为向量类型存储）：
+```sql
+INSERT INTO items VALUES (1, '[1,2,3]');
+```
+* 支持向量类型的算术运算（加法（+），减法（-），乘法（*），比较运算）：
+```sql
+select embedding + '[1.5,2.3,3.3]', embedding - '[1,2,3]', '[1,2,3]' - embedding from items where embedding > '[0,0,0]';
+```
+其中，算术运算为逐个元素运算，如 `[1,2,3] + [1,1,1] = [2,3,4]`；比较运算为逐个元素的字典序比较，如`[1,2,3]<[1,2,4], [2,1,2]>[1,2,2]`
+* 支持距离表达式计算：
+  * l2_distance
+    *  语法：l2_distance(vector A, vector B)

+
+### 题目二：向量类型扩展
+
+支持使用列表（如：`[1,2,3]`）来表示向量：
+```sql
+select embedding + [1.5,2.3,3.3], embedding - '[1,2,3]',[1,2,3] - embedding from items where embedding > [0,0,0];
+```
+
+### 题目三：高维向量
+
+* 需要支持最大 16000 维向量的存储和检索。
+* 不需要考虑在高维向量上建立向量索引。
+* 高维向量的存储可以参考 TEXT 类型的实现。
+
+### 题目四：向量索引（一）
+在本次赛题中，需要实现 IVF-Flat 向量索引，下面简单介绍 IVF-Flat 向量索引的工作原理及相关语法。
+IVF-Flat 是一种常见的高效近似最近邻（Approximate Nearest Neighbor，ANN）搜索算法，尤其适用于大型、高维向量数据集。它通过一种称为倒排文件索引（Inverted File Index）的机制来加速向量检索。IVF-Flat 的主要思想是将所有的高维向量分为多个簇，然后在每个簇内进行精确的向量搜索。这种方法通过减少需要比较的向量数量，大大提高了搜索速度。
+
+具体来说，IVF-Flat 包括两个主要步骤：
+
+* 向量分组（簇划分）：将所有向量通过聚类算法（如 K-Means）分为多个簇。每个簇都有一个中心点（质心），所有向量都分配到离它最近的质心。下面的左图表示将所有向量分为若干个簇。
+
+* 倒排文件索引：建立一个倒排文件索引，将向量的索引存储在对应簇的列表中。然后，通过这个索引来快速锁定需要比较的向量集合。下面的右图表示向量索引检索的过程。
+
+![ivfflat](images/ivfflat.png)
+以图像搜索为例的 IVF-Flat 向量索引工作流程如下：
+1. 首先使用 K-Means 算法将所有图像的特征向量分成 1000 个簇。每个簇表示一部分相似的图片。例如，簇 1 可能包含大部分是风景图像的向量，簇 2 可能包含大部分是人物图像的向量，以此类推。对于每个簇，向量索引都维护一个倒排文件索引，存储属于这个簇的所有图像的索引。
+比如，簇 1 对应的倒排文件索引可能包括 [image_23, image_45, image_78...]，这些是属于簇 1 的图像的索引。
+1. 查询过程：用户指定一张新图像进行搜索。首先，将这张图片通过同样的特征提取模型转换成一个高维向量。然后，通过计算这个向量与1000个质心的距离，找到离它最近的几个质心（假设是前5个）。在这几个质心对应的簇中，你进一步进行精确的向量搜索，找到最相似的图像。
+
+
+向量索引语法：
+```sql
+CREATE VECTOR INDEX vector_idx 
+ON items (embedding) 
+WITH (distance=l2_distance, type=ivfflat, lists=245, probes=5);
+```
+其中 embedding 是向量索引列，必须指定是 vector 类型，`VECTOR INDEX` 必须搭配使用。vector_idx 是向量索引名，`WITH` 后面为创建向量索引的基本参数, 括号内部是一个表达式列表 其中的 distance 表示距离算法，必须是 `inner_product`，`l2_distance`，`cosine_distance` 其中的一种，type 为索引算法类型，当前只支持 ivfflat。distance 和 type 必须指定。注意：所有的关键字都是大小写不敏感的。
+
+邻近向量检索语法：
+```sql
+select column_name1,column_name2, ... from table_name order by vector_distance_func(vector_column_name, '[float0,float1,……]') limit K;
+```
+* vector_distance_func是向量距离表达式：
+  * l2_distance
+  * inner_product
+  * cosine_distance
+* 要求order by子句表达式必须是一个向量距离表达式，且目前只支持向量列与常量向量
+* 要求limit子句必须是一个整数常量表达式
+
+本题目中只需要支持：
+1. 创建 Ivf-Flat 向量索引（本题目不考察 ANN 查询）。
+2. 当查询为邻近向量检索且命中向量索引时，需要将 order by + limit 的查询计划改写为通过向量索引进行检索的查询计划。
+
+向量索引检索的查询计划示例如下：
+```sql
+EXPLAIN SELECT C1, L2_DISTANCE(C1, '[1,2,3]') FROM TEST ORDER BY L2_DISTANCE('[1,2,3]', C1) LIMIT 3;
+
+Query Plan
+OPERATOR(NAME)
+PROJECT
+└─VECTOR_INDEX_SCAN(V_I ON TEST)
+```
+
+### 题目五：向量索引题目（二）
+
+* 需要在没有索引的场景下，支持向量检索功能（即精确检索）。
+* 需要支持完整的向量检索功能（包括向量索引构建，向量索引查询）。
+
+向量检索示例：
+```sql
+SELECT * FROM TAB_VEC ORDER BY L2_DISTANCE(B, '[1,2,3]') LIMIT 1;
+```
+
+### 题目六：ann-benchmarks
+
+[ann-benchmarks](https://github.com/erikbern/ann-benchmarks) 是一个用于评估近似最近邻（Approximate Nearest Neighbor, ANN）搜索算法性能的工具和框架。我们使用 ann-benchmarks 来测试 MiniOB 向量搜索相关功能。
+本地运行支持 MiniOB 的 ann-benchmarks 测试的步骤如下：
+
+赛题测试程序中运行的 ann-benchmarks 只针对 `fashion-mnist-784-euclidean` 数据集进行测试，`--runs` 参数为1，测试使用的 python 脚本与 [ann-benchmarks](https://github.com/nautaa/ann-benchmarks/tree/miniob_ann) 完全相同，指定向量索引参数 `probes = 5, lists = 245`。
+测试程序不对性能做过多的限制，满足如下要求即为通过：
+1. 要求在 10 分钟内完成 ann-benchmarks 的整个运行（即包括：插入数据，创建索引，ANN 查询，不包括下载数据集的时间）。
+2. 要求 ANN 查询的每秒查询数（QPS）达到 100 qps
+3. 要求 ANN 查询的召回率（recall）达到 0.90
+4. 考虑向量索引的内存占用，要求 ann-benchmarks 运行过程中 miniob 的最大内存占用不超过 1 GB。
+
+注意: 需要对 MiniOB 代码进行修改，以支持运行 ann-benchmarks 测试（如MiniOB 现有的 MySQL 通讯协议需要兼容 ann-benchmarks 所使用的 pymysql）。
+
+#### 在 MiniOB 上运行 ann-benchmark
+
+1. 下载 ann-benchmarks 代码
+```
+git clone https://github.com/nautaa/ann-benchmarks.git -b miniob_ann
+```
+1. 安装所需 python 依赖
+```
+cd ann-benchmarks/
+pip install -r requirements.txt
+```
+1. 以 mysql 通讯协议且监听 unix socket 的方式启动 miniob.
+```bash
+# 示例命令
+/root/miniob/build_release/bin/observer -s /tmp/miniob.sock -P mysql 
+```
+1. 运行 ann-benchmark.
+注意：需要将 `algorithms/miniob/config.yml` 中的 `arg_groups: [{unix_socket: "/tmp/miniob.sock"}]` 修改为 miniob 实际使用的 unix socket 文件地址
+```bash
+# 示例命令
+python3 run.py --dataset fashion-mnist-784-euclidean --docker-tag ann-benchmarks-miniob --local --timeout 100 --runs 1
+```
+1. 生成运行结果.
+```bash
+# 示例命令
+python3 plot.py --dataset fashion-mnist-784-euclidean
+# 示例输出如下，其中每行结果倒数第一个值为该算法对应的QPS，每行结果倒数第二个值为该算法对应的召回率。

+
+### MiniOB 向量数据库语法示例
+
+```sql
+-- 建表语句
+CREATE TABLE TEST (ID INT, C1 VECTOR(3), C2 VECTOR(3), C3 VECTOR(4));
+
+-- 插入语句
+INSERT INTO TEST VALUES(1, '[1,1,1]', '[1,2,3]', '[1,2,3,4]');
+
+-- 查询语句
+SELECT C1, C2, L2_DISTANCE(C1, C2), L2_DISTANCE('[1,1,1]', '[1,2,3]'), COSINE_DISTANCE('[1,1,1]', C2) FROM TEST;
+SELECT C1, C2, C1 + '[1.5,2.3,3.3]', '[3.3,55.55,66.66]' - C2, C2 * C1 FROM TEST;
+
+-- 创建索引
+CREATE VECTOR INDEX V_I ON TAB_VEC(B) WITH(TYPE=IVFFLAT, DISTANCE=L2_DISTANCE, LISTS=3, PROBES=3);
+
+-- ANN 查询
+SELECT * FROM TAB_VEC ORDER BY L2_DISTANCE(B, '[1,2,3]') LIMIT 1;

-# Date实现解析
-
-> 此实现解析有往届选手提供。具体代码实现已经有所变更，因此仅供参考。
-
-## DATE的存储
-
-
-一种实现方式：date以int类型的YYYYMMDD格式保存，比如2021-10-21，保存为整数就是2021\*1000 + 10\*100 + 21，在select展示时转成字符串YYYY-MM-DD格式，注意月份和天数要使用0填充。
-
-在parse.cpp中，参考
-
-```c++
-int value_init_date(Value* value, const char* v) {
-    value->type = DATES;
-    int y,m,d;
-    sscanf(v, "%d-%d-%d", &y, &m, &d);//not check return value eq 3, lex guarantee
-    bool b = check_date(y,m,d);
-    if(!b) return -1;
-    int dv = y*10000+m*100+d;
-    value->data = malloc(sizeof(dv));//TODO:check malloc failure
-    memcpy(value->data, &dv, sizeof(dv));
-    return 0;
-}
-```
-
-## 修改点
-
-### 语法上修改支持
-
-需要可匹配date的token词和DATE_STR值（一定要先于SSS，因为date的输入DATE_STR是SSS的子集)
-
-语法(yacc文件)上增加type，value里增加DATE_STR值
-
-```c++
-[Dd][Aa][Tt][Ee]                     RETURN_TOKEN(DATE_T);  // 增加DATE的token，需要在yacc文件中增加DATE_T的token
-
-{QUOTE}[0-9]{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01]){QUOTE} yylval->string=strdup(yytext); RETURN_TOKEN(DATE_STR);  // 使用正则表达式过滤DATE。需要在yacc文件中增加 %token <string> DATE_STR
-```
-
-同时，需要增加一个DATE类型，与INTS,FLOATS等含义相同：
-
-```c++
-// in parse_defs.h
-typedef enum { UNDEFINED, CHARS, INTS, FLOATS, DATES, TEXTS, NULLS } AttrType;
-```
-
-### Date的合法性判断
-
-输入日期的格式可以在词法分析时正则表达式里过滤掉。润年，大小月日期的合法性在普通代码中再做进一步判断。
-
-在parse阶段，对date做校验，并格式化成int值保存（参考最前面的代码），同时对日期的合法性做校验，参考：
-
-```c++
-bool check_date(int y, int m, int d)
-{
-    static int mon[] = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
-    bool leap = (y%400==0 || (y%100 && y%4==0));
-    return y > 0
-        && (m > 0)&&(m <= 12)
-        && (d > 0)&&(d <= ((m==2 && leap)?1:0) + mon[m]);
-}
-```
-
-### 增加新的类型date枚举
-
-代码里有多处和类型耦合地方（增加一个类型，要动很多处离散的代码，基础代码在这方面的可维护性不好)
-
-包括不限于，以下几处：
-
-- DefaultConditionFilter
-需要增加DATES类型的数据对比。因为这里将date作为整数存储，那么可以直接当做INTS来对比，比如：
-
-```c++
-    case INTS: 
-    case DATES: {
-      // 没有考虑大小端问题
-      // 对int和float，要考虑字节对齐问题,有些平台下直接转换可能会跪
-                               int left = *(int *)left_value;
-                               int right = *(int *)right_value;
-                               cmp_result = left - right;
-    } break;
-```
-
-- BplusTreeScanner
-与 `DefaultConditionFilter` 类似，也需要支持DATE类型的对比，可以直接当做整数比较。参考其中一块代码：
-
-```c++
-case INTS:case DATES: {
-      i1 = *(int *) pdata;
-      i2 = *(int *) pkey;
-      if (i1 > i2)
-        return 1;
-      if (i1 < i2)
-        return -1;
-      if (i1 == i2)
-        return 0;
-    }
-      break;
-```
-
-- ATTR_TYPE_NAME(storage/common/field_meta.cpp)
-保存元数据时，需要这里的信息，比较简单，参考：
-
-```c++
-const char *ATTR_TYPE_NAME[] = {
-  "undefined",
-  "chars",
-  "ints",
-  "floats",
-  "dates"
-};
-```
-
-- insert_record_from_file（storage/default/default_storage_stage.cpp）
-
-这个接口主要是为了支持从文件导入数据的，同样，实现可以与int类型保持一致。
-
-```c++
-switch (field->type()) {
-        case INTS: case DATES:{
-        deserialize_stream.clear(); // 清理stream的状态，防止多次解析出现异常
-        deserialize_stream.str(file_value);
-
-        int int_value;
-        deserialize_stream >> int_value;
-        if (!deserialize_stream || !deserialize_stream.eof()) {
-          errmsg << "need an integer but got '" << file_values[i]
-                 << "' (field index:" << i << ")";
-
-          rc = RC::SCHEMA_FIELD_TYPE_MISMATCH;
-        } else {
-          value_init_integer(&record_values[i], int_value);
-        }
-      }
-```
-
-### Date select展示
-
-TupleRecordConverter::add_record时做格式转换，需要按照输出要求，将日期类型数据，转换成合适的字符串。参考：
-
-```c++
-case DATES: {
-  int value = *(int*)(record + field_meta->offset());
-  char buf[16] = {0};
-  snprintf(buf,sizeof(buf),"%04d-%02d-%02d",value/10000,    (value%10000)/100,value%100); // 注意这里月份和天数，不足两位时需要填充0
-  tuple.add(buf,strlen(buf));
-}
-break;
-```
-
-### 异常失败处理
-
-只要输入的日期不合法，输出都是FAILURE\n。包括查询的where条件、插入的日期值、更新的值等。这里在解析时(parse.cpp)中就可以直接返回错误。
-
-## 自测覆盖点
-
-1. 日期输入，包括合法和非法日期格式。非法日期可以写单元测试做。
-2. 日期值比较=、 >、 <、 >=、 <=
-3. 日期字段当索引。很多同学漏掉了这个点。
-4. 日期展示格式，注意月份和天数补充0

-title: Drop table 实现解析
----
-
-# miniob - drop table 实现解析
-
-> 此实现解析有往届选手提供。具体代码实现已经有所变更，因此仅供参考。
-
-**代码部分主要添加在：**
-
-drop table 与create table相反，要清理掉所有创建表和表相关联的资源，比如描述表的文件、数据文件以及索引等相关数据和文件。
-
-sql流转到default_storge阶段的时候，在处理sql的函数中，新增一个drop_table的case。
-
-drop table就是删除表，在`create table t`时，会新建一个t.table文件，同时为了存储数据也会新建一个t.data文件存储下来。同时创建索引的时候，也会创建记录索引数据的文件，在删除表时也要一起删除掉。
-
-那么删除表，就需要**删除t.table文件、t.data文件和关联的索引文件**。
-
-同时由于buffer pool的存在，在新建表和插入数据的时候，会写入buffer pool缓存。所以drop table，不仅需要删除文件，也需要**清空buffer pool** ，防止在数据没落盘的时候，再建立同名表，仍然可以查询到数据。
-
-如果建立了索引，比如t_id on t(id)，那么也会新建一个t_id.index文件，也需要删除这个文件。
-
-这些东西全部清空，那么就完成了drop table。
-
-具体的代码实现如下：
-在default_storage_stage.cpp 中的处理SQL语句的case中增加一个
-
-```c++
-  case SCF_DROP_TABLE: {
-    const DropTable& drop_table = sql->sstr[sql->q_size-1].drop_table; // 拿到要drop 的表
-    rc = handler_->drop_table(current_db,drop_table.relation_name); // 调用drop table接口，drop table要在handler中实现
-    snprintf(response,sizeof(response),"%s\n", rc == RC::SUCCESS ? "SUCCESS" : "FAILURE"); // 返回结果，带不带换行符都可以
-  }
-break;
-```
-
-在default_handler.cpp文件中，实现handler的drop_table接口：
-
-```c++
-RC DefaultHandler::drop_table(const char *dbname, const char *relation_name) {
-  Db *db = find_db(dbname);  // 这是原有的代码，用来查找对应的数据库，不过目前只有一个库
-  if(db == nullptr) {
-    return RC::SCHEMA_DB_NOT_OPENED;
-  }
-  return db->drop_table(relation_name); // 直接调用db的删掉接口
-}
-```
-
-在db.cpp中，实现drop_table接口
-
-```c++
-RC Db::drop_table(const char* table_name)
-{
-    auto it = opened_tables_.find(table_name);
-    if (it == opened_tables_.end())
-    {
-        return SCHEMA_TABLE_NOT_EXIST; // 找不到表，要返回错误，测试程序中也会校验这种场景
-    }
-    Table* table = it->second;
-    RC rc = table->destroy(path_.c_str()); // 让表自己销毁资源
-    if(rc != RC::SUCCESS) return rc;
-
-    opened_tables_.erase(it); // 删除成功的话，从表list中将它删除
-    delete table;
-    return RC::SUCCESS;
-}
-```
-
-table.cpp中清理文件和相关数据
-
-```c++
-RC Table::destroy(const char* dir) {
-    RC rc = sync();//刷新所有脏页
-
-    if(rc != RC::SUCCESS) return rc;
-
-    std::string path = table_meta_file(dir, name());
-    if(unlink(path.c_str()) != 0) {
-        LOG_ERROR("Failed to remove meta file=%s, errno=%d", path.c_str(), errno);
-        return RC::GENERIC_ERROR;
-    }
-
-    std::string data_file = std::string(dir) + "/" + name() + TABLE_DATA_SUFFIX;
-    if(unlink(data_file.c_str()) != 0) { // 删除描述表元数据的文件
-        LOG_ERROR("Failed to remove data file=%s, errno=%d", data_file.c_str(), errno);
-        return RC::GENERIC_ERROR;
-    }
-
-    std::string text_data_file = std::string(dir) + "/" + name() + TABLE_TEXT_DATA_SUFFIX;
-    if(unlink(text_data_file.c_str()) != 0) { // 删除表实现text字段的数据文件（后续实现了text case时需要考虑，最开始可以不考虑这个逻辑）
-        LOG_ERROR("Failed to remove text data file=%s, errno=%d", text_data_file.c_str(), errno);
-        return RC::GENERIC_ERROR;
-    }
-
-    const int index_num = table_meta_.index_num();
-    for (int i = 0; i < index_num; i++) {  // 清理所有的索引相关文件数据与索引元数据
-        ((BplusTreeIndex*)indexes_[i])->close();
-        const IndexMeta* index_meta = table_meta_.index(i);
-        std::string index_file = index_data_file(dir, name(), index_meta->name());
-        if(unlink(index_file.c_str()) != 0) {
-            LOG_ERROR("Failed to remove index file=%s, errno=%d", index_file.c_str(), errno);
-            return RC::GENERIC_ERROR;
-        }
-    }
-    return RC::SUCCESS;

-title: Date 测试解说
----
-
-> 此实现解析有往届选手提供。具体代码实现已经有所变更，因此仅供参考。
-
-miniob-date 测试解说
-
-本篇文章针对在miniob中增加date字段类型做解析，希望可以帮助参加比赛的同学能够顺利通过。
-
-# 题目描述
-
-date测试不会超过2038年2月，不会小于1970年1月1号。注意处理非法的date输入，需要返回FAILURE。  
-
-## 测试示例
-
-create table t(id int, birthday date);
-
-insert into t values(1, '2020-09-10');
-
-insert into t values(2, '2021-1-2');
-
-select * from t;
-
-> 注意：所有的字符都是英文。浏览器如果将英文字符转成中文字符，请留意。
-
-# 如何选择date的存储长度
-
-当前已经有的字段类型有：INTS/FLOATS/CHARS，这几个字段的内存大小都是4个字节。而题目中要求 date 类型，时间范围在1970年1月1日和2038年2月之间，说明date 字段也可以用4个字段来存储。这个原理可以参考time函数的说明，4个字节存储的时间戳，如果起始时间是1970年1月1日，那么将会在2038年某一天越界，而这一天是在2038年2月之后的。因此 date 字段也可以使用 `4 字节`存储。
-
-使用4字节存储的好处还有，可以将4字节数据直接当做一个整数来处理，这样做比较运算时，也可以直接使用整数运算。
-
-
-# 如何解析date 相关SQL
-
-date作为一个关键字，可以直接在lex文件中添加。
-
-\[Dd\]\[Aa\]\[Tt\]\[Ee\]                         RETURN_TOKEN(DATE);
-
-当然也需要增加token DATE。
-
-对于日期数据，比如"2021-10-25"，建议不要在词法解析和语法解析模块中写正则表达式来解析，因为它本身就是一个字符串。如果写正则表达式来解析，那就不能再将它作为普通字符串来处理，另外，正则表达式规则将会非常复杂，难以维护和扩展。比如我想让日期支持更多的格式："2021/10/25"，"2021年10月25日"；对与普通的字符串字段，理论上是能够接收"2021-10-25"，这样的字符串作为参数去更新或插入的，如果在词法/语法解析中处理，那还需要处理使用日期更新字符串字段的场景。
-
-
-
-# 需要考虑的场景
-
-## 日期解析
-
-需要判断类型为日期的地方，都需要按照一定格式去解析日期。当前输入格式年月日是按照'-'来分隔的，这样就非常简单了。将字符串分割为3个字符串，然后分别当成数字解析就可以。
-
-
-
-## 日期是否合法
-
-用字符串表示日期是有合法性要求的。比如2021-02-30，就不能算是正确的日期。
-
-可能出现日期的地方有（不一定全面）：
-
-- 插入数据的值；
-
-- 更新数据的值；
-
-- 比较条件中的日期；
-
-考虑再周全一点，可以支持一下聚合函数中有date数据类型。
-
-
-
-## 建表
-
-建表需要支持date类型字段
-
-## 建索引
-
-当前Miniob默认支持了B+-Tree索引，需要对这个索引做扩展。
-
-## 日期比较
-
-查询条件中可能有日期，查询可能是通过索引查询，也可能只是普通的查询。
-
-
-
-## 输出格式
-
-注意按照题目提示来输出 "YYYY-mm-dd"，位数不够，需要用'0'填充。
