你可以通过在 ClickHouse 中创建一个 [External Dictionary](../../sql-reference/dictionaries/external-dictionaries/external-dicts.md) 来解码这些值。
|
||||||
|
|
||||||
|
## 用例：合并地理数据 {#use-case}
|
||||||
|
|
||||||
|
使用 `pointInPolygon` 函数。
|
||||||
|
|
||||||
|
1. 创建一个用于存储多边形的表：
|
||||||
|
|
||||||
|
<Tabs groupId="deployMethod">
|
||||||
|
<TabItem value="serverless" label="ClickHouse Cloud" default>
|
||||||
|
|
||||||
|
```sql
|
||||||
|
CREATE TABLE moscow (polygon Array(Tuple(Float64, Float64)))
|
||||||
|
ORDER BY polygon;
|
||||||
|
```
|
||||||
|
|
||||||
|
</TabItem>
|
||||||
|
<TabItem value="selfmanaged" label="Self-managed">
|
||||||
|
|
||||||
|
```sql
|
||||||
|
CREATE TEMPORARY TABLE
|
||||||
|
moscow (polygon Array(Tuple(Float64, Float64)));
|
||||||
|
```
|
||||||
|
|
||||||
|
</TabItem>
|
||||||
|
</Tabs>
|
||||||
|
|
||||||
|
2. 以下点大致上构造了莫斯科的地理围栏（除“新莫斯科”外）：
|
||||||
|
|
||||||
|
```sql
|

该数据集由纽约公共图书馆创建。其中含有有关酒店、餐馆和咖啡馆的菜单上的菜肴及其价格的历史数据。
|
||||||
|
|
||||||
<Content />
|
来源：http://menus.nypl.org/data
|
||||||
|
数据为开放数据。
|
||||||
|
|
||||||
|
数据来自于图书馆中的档案，因此可能不完整，以至于难以进行统计分析。尽管如此，该数据集也是非常有意思的。数据集中只有 130 万条关于菜单中的菜肴的记录 - 这对于 ClickHouse 来说是一个非常小的数据量，但这仍是一个很好的例子。
|
||||||
|
|
||||||
|
## 下载数据集 {#download-dataset}
|
||||||
|
|
||||||
|
运行命令：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
wget https://s3.amazonaws.com/menusdata.nypl.org/gzips/2021_08_01_07_01_17_data.tgz
|
||||||
|
```
|
||||||
|
|
||||||
|
如果有需要可以使用 http://menus.nypl.org/data 中的最新链接。下载的大小约为 35 MB。
|
||||||
|
|
||||||
|
## 解压数据集 {#unpack-dataset}
|
||||||
|
|
||||||
|
```bash
|
||||||
|
tar xvf 2021_08_01_07_01_17_data.tgz
|
||||||
|
```
|
||||||
|
|
||||||
|
解压后的的大小约为 150 MB。
|
||||||
|
|
||||||
|
数据集由四个表组成：
|
||||||
|
|
||||||
|
- `Menu` - 有关菜单的信息，其中包含：餐厅名称，看到菜单的日期等
|
||||||
|
- `Dish` - 有关菜肴的信息，其中包含：菜肴名称以及一些特征。
|
||||||
|
- `MenuPage` - 有关菜单中页面的信息，每个页面都属于某个 `Menu`。
|
||||||
|
- `MenuItem` - 菜单项。某个菜单页面上的菜肴及其价格：指向 `Dish` 和 `MenuPage`的链接。
|
||||||
|
|
||||||
|
## 创建表 {#create-tables}
|
||||||
|
|
||||||
|
使用 [Decimal](/docs/zh/sql-reference/data-types/decimal.md) 数据类型来存储价格。
|
||||||
|
|
||||||
|
```sql
|
||||||
|
CREATE TABLE dish
|
||||||
|
(
|
||||||
|
id UInt32,
|
||||||
|

|
||||||
|

|
||||||
|
) ENGINE = MergeTree ORDER BY id;
|
||||||
|
|
||||||
|
CREATE TABLE menu
|

dish_count UInt16
|
||||||
|
) ENGINE = MergeTree ORDER BY id;
|
||||||
|
|
||||||
|
CREATE TABLE menu_page
|

|

|
||||||
|
) ENGINE = MergeTree ORDER BY id;
|
||||||
|
|
||||||
|
CREATE TABLE menu_item
|
||||||
|
(
|
||||||
|

|
||||||
|
menu_page_id UInt32,
|
||||||
|
price Decimal64(3),
|
||||||
|
high_price Decimal64(3),
|
||||||
|
dish_id UInt32,
|
||||||
|
created_at DateTime,
|
||||||
|
updated_at DateTime,
|
||||||
|
xpos Float64,
|
||||||
|
ypos Float64
|
||||||
|
) ENGINE = MergeTree ORDER BY id;
|
||||||
|
```
|
||||||
|
|
||||||
|
## 导入数据 {#import-data}
|
||||||
|
|
||||||
|
执行以下命令将数据导入 ClickHouse：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
clickhouse-client --format_csv_allow_single_quotes 0 --input_format_null_as_default 0 --query "INSERT INTO dish FORMAT CSVWithNames" < Dish.csv
|
||||||
|
clickhouse-client --format_csv_allow_single_quotes 0 --input_format_null_as_default 0 --query "INSERT INTO menu FORMAT CSVWithNames" < Menu.csv
|
||||||
|
clickhouse-client --format_csv_allow_single_quotes 0 --input_format_null_as_default 0 --query "INSERT INTO menu_page FORMAT CSVWithNames" < MenuPage.csv
|
||||||
|
clickhouse-client --format_csv_allow_single_quotes 0 --input_format_null_as_default 0 --date_time_input_format best_effort --query "INSERT INTO menu_item FORMAT CSVWithNames" < MenuItem.csv
|
||||||
|
```
|
||||||
|
|
||||||
|
因为数据由带有标题的 CSV 表示，所以使用 [CSVWithNames](/docs/zh/interfaces/formats.md#csvwithnames) 格式。
|
||||||
|
|
||||||
|
因为只有双引号用于数据字段，单引号可以在值内，所以禁用了 `format_csv_allow_single_quotes` 以避免混淆 CSV 解析器。
|
||||||
|
|
||||||
|
因为数据中没有 [NULL](/docs/zh/sql-reference/syntax.md#null-literal) 值，所以禁用 [input_format_null_as_default](/docs/zh/operations/settings/settings.md#settings-input-format-null-as-default)。不然 ClickHouse 将会尝试解析 `\N` 序列，并可能与数据中的 `\` 混淆。
|
||||||
|
|
||||||
|
设置 [date_time_input_format best_effort](/docs/zh/operations/settings/settings.md#settings-date_time_input_format) 以便解析各种格式的 [DateTime](/docs/zh/sql-reference/data-types/datetime.md)字段。例如，识别像“2000-01-01 01:02”这样没有秒数的 ISO-8601 时间字符串。如果没有此设置，则仅允许使用固定的 DateTime 格式。
|
||||||
|
|
||||||
|
## 非规范化数据 {#denormalize-data}
|
||||||
|
|
||||||
|
数据以 [规范化形式] (https://en.wikipedia.org/wiki/Database_normalization#Normal_forms) 在多个表格中呈现。这意味着如果你想进行如查询菜单项中的菜名这类的查询，则必须执行 [JOIN](/docs/zh/sql-reference/statements/select/join.md#select-join)。在典型的分析任务中，预先处理联接的数据以避免每次都执行“联接”会更有效率。这中操作被称为“非规范化”数据。
|
||||||
|
|
||||||
|
我们将创建一个表“menu_item_denorm”，其中将包含所有联接在一起的数据：
|
||||||
|
|
||||||
|
```sql
|
||||||
|
CREATE TABLE menu_item_denorm
|
||||||
|
ENGINE = MergeTree ORDER BY (dish_name, created_at)

## 下载数据集 {#download-dataset}
|
||||||
|
|
||||||
|
运行命令：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
wget -O- https://zenodo.org/record/5092942 | grep -oP 'https://zenodo.org/record/5092942/files/flightlist_\d+_\d+\.csv\.gz' | xargs wget
|
||||||
|
```
|
||||||
|
|
||||||
|
Download will take about 2 minutes with good internet connection. There are 30 files with total size of 4.3 GB.
|
||||||
|
|
||||||
|
## 创建表 {#create-table}
|
||||||
|
|
||||||
|
```sql
|
||||||
|
CREATE TABLE opensky
|
||||||
|
(
|
||||||
|
callsign String,
|
||||||
|
number String,
|
||||||
|
icao24 String,
|
||||||
|
registration String,
|
||||||
|
typecode String,
|
||||||
|
origin String,
|
||||||
|
destination String,
|
||||||
|
firstseen DateTime,
|
||||||
|
lastseen DateTime,
|
||||||
|
day DateTime,
|
||||||
|
latitude_1 Float64,
|
||||||
|
longitude_1 Float64,
|
||||||
|
altitude_1 Float64,
|
||||||
|
latitude_2 Float64,
|
||||||
|
longitude_2 Float64,
|
||||||
|
altitude_2 Float64
|
||||||
|
) ENGINE = MergeTree ORDER BY (origin, destination, callsign);
|
||||||
|
```
|
||||||
|
|
||||||
|
## 导入数据 {#import-data}
|
||||||
|
|
||||||
|
将数据并行导入到 ClickHouse：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
ls -1 flightlist_*.csv.gz | xargs -P100 -I{} bash -c 'gzip -c -d "{}" | clickhouse-client --date_time_input_format best_effort --query "INSERT INTO opensky FORMAT CSVWithNames"'
|
||||||
|
```
|
||||||
|
|
||||||
|
- 这里我们将文件列表（`ls -1 flightlist_*.csv.gz`）传递给`xargs`以进行并行处理。 `xargs -P100` 指定最多使用 100 个并行工作程序，但由于我们只有 30 个文件，工作程序的数量将只有 30 个。
|
||||||
|
- 对于每个文件，`xargs` 将通过 `bash -c` 为每个文件运行一个脚本文件。该脚本通过使用 `{}` 表示文件名占位符，然后 `xargs` 由命令进行填充（使用 `-I{}`）。
|
||||||
|
- 该脚本会将文件 (`gzip -c -d "{}"`) 解压缩到标准输出（`-c` 参数），并将输出重定向到 `clickhouse-client`。
|
||||||
|
- 我们还要求使用扩展解析器解析 [DateTime](../../sql-reference/data-types/datetime.md) 字段 ([--date_time_input_format best_effort](../../operations/settings/ settings.md#settings-date_time_input_format)) 以识别具有时区偏移的 ISO-8601 格式。
|
||||||
|
|
||||||
|
最后，`clickhouse-client` 会以 [CSVWithNames](../../interfaces/formats.md#csvwithnames) 格式读取输入数据然后执行插入。
|
||||||
|
|
||||||
|
并行导入需要 24 秒。
|
||||||
|
|
||||||
|
如果您不想使用并行导入，以下是顺序导入的方式：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
for file in flightlist_*.csv.gz; do gzip -c -d "$file" | clickhouse-client --date_time_input_format best_effort --query "INSERT INTO opensky FORMAT CSVWithNames"; done
|
||||||
|
```
|
||||||
|
|
||||||
|

||||||

## 下载并解压数据集
|
||||||
|
|
||||||
|
1. 进入下载页面[https://recipenlg.cs.put.poznan.pl/dataset](https://recipenlg.cs.put.poznan.pl/dataset)。
|
||||||
|
2. 接受条款和条件并下载 zip 文件。
|
||||||
|
3. 使用 `unzip` 解压 zip 文件，得到 `full_dataset.csv` 文件。
|
||||||
|
|
||||||
|
## 创建表
|
||||||
|
|
||||||
|
运行 clickhouse-client 并执行以下 CREATE 请求：
|
||||||
|
|
||||||
|
``` sql
|
||||||
|
CREATE TABLE recipes
|
||||||
|
(
|
||||||
|
title String,
|
||||||
|
ingredients Array(String),
|
||||||
|
directions Array(String),
|
||||||
|
link String,
|
||||||
|
source LowCardinality(String),
|
||||||
|
NER Array(String)
|
||||||
|
) ENGINE = MergeTree ORDER BY title;
|
||||||
|
```
|
||||||
|
|
||||||
|
## 插入数据
|
||||||
|
|
||||||
|
运行以下命令：
|
||||||
|
|
||||||
|
``` bash
|
||||||
|
clickhouse-client --query "
|
||||||
|
INSERT INTO recipes
|
||||||
|
SELECT
|
||||||
|
title,
|
||||||
|
JSONExtract(ingredients, 'Array(String)'),
|
||||||
|
JSONExtract(directions, 'Array(String)'),
|
||||||
|
link,
|
||||||
|
source,
|
||||||
|
JSONExtract(NER, 'Array(String)')
|
||||||
|
FROM input('num UInt32, title String, ingredients String, directions String, link String, source LowCardinality(String), NER String')
|
||||||
|
FORMAT CSVWithNames
|
||||||
|
" --input_format_with_names_use_header 0 --format_csv_allow_single_quote 0 --input_format_allow_errors_num 10 < full_dataset.csv
|
||||||
|
```
|
||||||
|
|
||||||
|
这是一个展示如何解析自定义 CSV，这其中涉及了许多调整。
|
||||||
|
|
||||||
|
说明：
|
||||||
|
- 数据集为 CSV 格式，但在插入时需要一些预处理；使用表函数 [input](../../sql-reference/table-functions/input.md) 进行预处理；
|
||||||
|
- CSV 文件的结构在表函数 `input` 的参数中指定；
|
||||||
|
- 字段 `num`（行号）是不需要的 - 可以忽略并从文件中进行解析；
|
||||||
|
- 使用 `FORMAT CSVWithNames`，因为标题不包含第一个字段的名称，因此 CSV 中的标题将被忽略（通过命令行参数 `--input_format_with_names_use_header 0`）；
|
||||||
|
- 文件仅使用双引号将 CSV 字符串括起来；一些字符串没有用双引号括起来，单引号也不能被解析为括起来的字符串 - 所以添加`--format_csv_allow_single_quote 0`参数接受文件中的单引号；
|
||||||
|
- 由于某些 CSV 的字符串的开头包含 `\M/` 因此无法被解析； CSV 中唯一可能以反斜杠开头的值是 `\N`，这个值被解析为 SQL NULL。通过添加`--input_format_allow_errors_num 10`参数，允许在导入过程中跳过 10 个格式错误；
|
||||||
|
- 在数据集中的 Ingredients、directions 和 NER 字段为数组；但这些数组并没有以一般形式表示：这些字段作为 JSON 序列化为字符串，然后放入 CSV 中 - 在导入是将它们解析为字符串，然后使用 [JSONExtract](../../sql-reference/functions/json-functions.md ) 函数将其转换为数组。
|
||||||
|
|
||||||
|
## 验证插入的数据
|
||||||
|
|
||||||
|
通过检查行数：
|
||||||
|
|
||||||
|
请求：
|
||||||
|
|
||||||
|
``` sql
|
||||||
|
SELECT count() FROM recipes;
|
||||||
|
```
|
||||||
|
|
||||||
|
结果：
|
||||||
|
|
||||||
|
``` text
|
||||||
|
┌─count()─┐
|
||||||
