`ASOF JOIN` is useful when you need to join records that have no exact match.
|
||||
|
||||
Tables for `ASOF JOIN` must have an ordered sequence column. This column cannot be alone in a table, and should be one of the data types: `UInt32`, `UInt64`, `Float32`, `Float64`, `Date`, and `DateTime`.
|
||||
Algorithm requires the special column in tables. This column:
|
||||
|
||||
- Must contain an ordered sequence.
|
||||
- Can be one of the following types: [Int*, UInt*](../../data-types/int-uint.md), [Float*](../../data-types/float.md), [Date](../../data-types/date.md), [DateTime](../../data-types/datetime.md), [Decimal*](../../data-types/decimal.md).
|
||||
- Can't be the only column in the `JOIN` clause.

当ClickHouse合并数据部分时，它会删除具有相同主键和版本但 `Sign`值不同的一对行. 行的顺序并不重要。
|
||||
|
||||
当ClickHouse插入数据时，它会按主键对行进行排序。 如果 `Version` 列不在主键中，ClickHouse将其隐式添加到主键作为最后一个字段并使用它进行排序。
|
||||
|
||||
## 选择数据 {#selecting-data}
|
||||
|
||||
ClickHouse不保证具有相同主键的所有行都将位于相同的结果数据部分中，甚至位于相同的物理服务器上。 对于写入数据和随后合并数据部分都是如此。 此外，ClickHouse流程 `SELECT` 具有多个线程的查询，并且无法预测结果中的行顺序。 这意味着聚合是必需的，如果有必要得到完全 “collapsed” 从数据 `VersionedCollapsingMergeTree` 桌子

ClickHouse不保证具有相同主键的所有行都将位于相同的结果数据部分中，甚至位于相同的物理服务器上。 对于写入数据和随后合并数据部分都是如此。 此外，ClickHouse流程 `SELECT` 具有多个线程的查询，并且无法预测结果中的行顺序。 这意味着，如果有必要从`VersionedCollapsingMergeTree` 表中得到完全 “collapsed” 的数据，聚合是必需的。
|
||||
|
||||
要完成折叠，请使用 `GROUP BY` 考虑符号的子句和聚合函数。 例如，要计算数量，请使用 `sum(Sign)` 而不是 `count()`. 要计算的东西的总和，使用 `sum(Sign * x)` 而不是 `sum(x)`，并添加 `HAVING sum(Sign) > 0`.
|
||||
|
||||
聚合 `count`, `sum` 和 `avg` 可以这样计算。 聚合 `uniq` 如果对象至少具有一个非折叠状态，则可以计算。 聚合 `min` 和 `max` 无法计算是因为 `VersionedCollapsingMergeTree` 不保存折叠状态值的历史记录。
|
||||
|
||||
如果您需要提取数据 “collapsing” 但是，如果没有聚合（例如，要检查是否存在其最新值与某些条件匹配的行），则可以使用 `FINAL` 修饰符 `FROM` 条款 这种方法效率低下，不应与大型表一起使用。

# 语法 {#syntax}
|
||||
|
||||
系统中有两种类型的解析器：完整SQL解析器（递归下降解析器）和数据格式解析器（快速流解析器）。
|
||||
在所有情况下，除了 `INSERT` 查询时，只使用完整的SQL解析器。
|
||||
该 `INSERT` 查询使用两个解析器:
|
||||
# SQL语法 {#syntax}
|
||||
|
||||
CH有2类解析器：完整SQL解析器（递归式解析器），以及数据格式解析器（快速流式解析器）
|
||||
除了 `INSERT` 查询，其它情况下仅使用完整SQL解析器。
|
||||
`INSERT`查询会同时使用2种解析器：
|
||||
``` sql
|
||||
INSERT INTO t VALUES (1, 'Hello, world'), (2, 'abc'), (3, 'def')
|
||||
```
|
||||
|
||||
该 `INSERT INTO t VALUES` 片段由完整的解析器解析，并且数据 `(1, 'Hello, world'), (2, 'abc'), (3, 'def')` 由快速流解析器解析。 您也可以通过使用 [input\_format\_values\_interpret\_expressions](../operations/settings/settings.md#settings-input_format_values_interpret_expressions) 设置。 当 `input_format_values_interpret_expressions = 1`，ClickHouse首先尝试使用fast stream解析器解析值。 如果失败，ClickHouse将尝试对数据使用完整的解析器，将其视为SQL [表达式](#syntax-expressions).
|
||||
含`INSERT INTO t VALUES` 的部分由完整SQL解析器处理，包含数据的部分 `(1, 'Hello, world'), (2, 'abc'), (3, 'def')` 交给快速流式解析器解析。通过设置参数 [input\_format\_values\_interpret\_expressions](../operations/settings/settings.md#settings-input_format_values_interpret_expressions)，你也可以对数据部分开启完整SQL解析器。当 `input_format_values_interpret_expressions = 1` 时，CH优先采用快速流式解析器来解析数据。如果失败，CH再尝试用完整SQL解析器来处理，就像处理SQL [expression](#syntax-expressions) 一样。
|
||||
|
||||
数据可以有任何格式。 当接收到查询时，服务器计算不超过 [max\_query\_size](../operations/settings/settings.md#settings-max_query_size) RAM中请求的字节（默认为1MB），其余的是流解析。
|
||||
它允许避免与大的问题 `INSERT` 查询。
|
||||
数据可以采用任何格式。当CH接受到请求时，服务端先在内存中计算不超过 [max\_query\_size](../operations/settings/settings.md#settings-max_query_size) 字节的请求数据（默认1 mb），然后剩下部分交给快速流式解析器。
|
||||
|
||||
使用时 `Values` 格式为 `INSERT` 查询，它可能看起来数据被解析相同的表达式 `SELECT` 查询，但事实并非如此。 该 `Values` 格式更为有限。
|
||||
这将避免在处理大型的 `INSERT`语句时出现问题。
|
||||
|
||||
本文的其余部分将介绍完整的解析器。 有关格式解析器的详细信息，请参阅 [格式](../interfaces/formats.md) 科。
|
||||
当 `INSERT` 语句中使用 `Values` 形式时，看起来 数据部分的解析和解析`SELECT` 中的表达式相同，但并不是这样的。 `Values` 形式非常有限。
|
||||
该篇的剩余部分涵盖了完整SQL解析器。关于格式解析的更多信息，参见 [Formats](../interfaces/formats.md) 章节。
|
||||
|
||||
## 空间 {#spaces}
|
||||
## 空字符 {#spaces}
|
||||
|
||||
语法结构之间可能有任意数量的空格符号（包括查询的开始和结束）。 空格符号包括空格、制表符、换行符、CR和换页符。
|
||||
sql语句中（包含sql的起始和结束）可以有任意的空字符，这些空字符类型包括：空格字符，tab制表符，换行符，CR符，换页符等。
|
||||
|
||||
## 评论 {#comments}
|
||||
## 注释 {#comments}
|
||||
|
||||
ClickHouse支持SQL风格和C风格的注释。
|
||||
SQL风格的注释以下开头 `--` 并继续到线的末尾，一个空格后 `--` 可以省略。
|
||||
C型是从 `/*` 到 `*/`并且可以是多行，也不需要空格。
|
||||
CH支持SQL风格或C语言风格的注释：
|
||||
- SQL风格的注释以 `--` 开始，直到行末，`--` 后紧跟的空格可以忽略
|
||||
- C语言风格的注释以 `/*` 开始，以 `*/` 结束，支持多行形式，同样可以省略 `/*` 后的空格
|
||||
|
||||
## 关键词 {#syntax-keywords}
|
||||
## 关键字 {#syntax-keywords}
|
||||
|
||||
当关键字对应于以下关键字时，不区分大小写:
|
||||
以下场景的关键字是大小写不敏感的：
|
||||
- 标准SQL。例如，`SELECT`, `select` 和 `SeLeCt` 都是允许的
|
||||
- 在某些流行的RDBMS中被实现的关键字，例如，`DateTime` 和 `datetime`是一样的
|
||||
|
||||
- SQL标准。 例如, `SELECT`, `select` 和 `SeLeCt` 都是有效的。
|
||||
- 在一些流行的DBMS（MySQL或Postgres）中实现。 例如, `DateTime` 是一样的 `datetime`.
|
||||
|
||||
数据类型名称是否区分大小写可以在 `system.data_type_families` 桌子
|
||||
你可以在系统表 [system.data_type_families](../operations/system-tables.md#system_tables-data_type_families) 中检查某个数据类型的名称是否是大小写敏感型。
|
||||
|
||||
与标准SQL相比，所有其他关键字（包括函数名称）都是 **区分大小写**.
|
||||
和标准SQL相反，所有其它的关键字都是 **大小写敏感的**，包括函数名称。
|
||||
In contrast to standard SQL, all other keywords (including functions names) are **case-sensitive**.
|
||||
|
||||
不保留关键字；它们仅在相应的上下文中被视为保留关键字。 如果您使用 [标识符](#syntax-identifiers) 使用与关键字相同的名称，将它们括在双引号或反引号中。 例如，查询 `SELECT "FROM" FROM table_name` 是有效的，如果表 `table_name` 具有名称的列 `"FROM"`.
|
||||
关键字不是保留的；它们仅在相应的上下文中才会被处理。如果你使用和关键字同名的 [变量名](#syntax-identifiers) ，需要使用双引号或转移符将它们包含起来。例如：如果表 `table_name` 包含列 `"FROM"`，那么 `SELECT "FROM" FROM table_name` 是合法的
|
||||
|
||||
## 标识符 {#syntax-identifiers}
|
||||
## 变量名 {#syntax-identifiers}
|
||||
|
||||
标识符是:
|
||||
变量包括：
|
||||
Identifiers are:
|
||||
|
||||
- 集群、数据库、表、分区和列名称。
|
||||
- 功能。
|
||||
- 数据类型。
|
||||
- [表达式别名](#syntax-expression_aliases).
|
||||
- 集群，数据库，表，分区，列名称
|
||||
- 函数
|
||||
- 数据类型
|
||||
- 表达式别名
|
||||
|
||||
标识符可以是引号或非引号。 后者是优选的。
|
||||
变量名可以使用反引号包含起来
|
||||
|
||||
非引号标识符必须与正则表达式匹配 `^[a-zA-Z_][0-9a-zA-Z_]*$` 并且不能等于 [关键词](#syntax-keywords). 例: `x, _1, X_y__Z123_.`
|
||||
没有使用反引号包含的变量名，必须匹配正则表达式 `^[a-zA-Z_][0-9a-zA-Z_]*$`，并且不能和 [关键字]相同
|
||||
|
||||
如果要使用与关键字相同的标识符，或者要在标识符中使用其他符号，请使用双引号或反引号对其进行引用，例如, `"id"`, `` `id` ``.
|
||||
如果想使用和关键字同名的变量名称，或者在变量名称中包含其它符号，你需要通过双引号或转义符号，例如： `"id"`, `` `id` ``
|
||||
|
||||
## 文字数 {#literals}
|
||||
## 字符 {#literals}
|
||||
|
||||
有数字，字符串，复合和 `NULL` 文字。
|
||||
CH包含数字，字母，括号，NULL值等字符
|
||||
|
||||
### 数字 {#numeric}
|
||||
|
||||
数值文字尝试进行分析:
|
||||
数字类型字符会被做如下解析：
|
||||
- 首先，当做64位的有符号整数，使用该函数 [strtoull](https://en.cppreference.com/w/cpp/string/byte/strtoul)
|
||||
- 如果失败，解析成64位无符号整数，同样使用函数 [strtoull](https://en.cppreference.com/w/cpp/string/byte/strtoul)
|
||||
|
||||
- 首先，作为一个64位有符号的数字，使用 [strtoull](https://en.cppreference.com/w/cpp/string/byte/strtoul) 功能。
|
||||
- 如果不成功，作为64位无符号数，使用 [strtoll](https://en.cppreference.com/w/cpp/string/byte/strtol) 功能。
|
||||
- 如果不成功，作为一个浮点数使用 [strtod](https://en.cppreference.com/w/cpp/string/byte/strtof) 功能。
|
||||
- 否则，将返回错误。
|
||||
- 如果还失败了，试图解析成浮点型数值，使用函数 [strtod](https://en.cppreference.com/w/cpp/string/byte/strtof)
|
||||
Numeric literal tries to be parsed:
|
||||
|
||||
文本值具有该值适合的最小类型。
|
||||
例如，1被解析为 `UInt8`，但256被解析为 `UInt16`. 有关详细信息，请参阅 [数据类型](../sql-reference/data-types/index.md).
|
||||
- 最后，以上情形都不符合时，返回异常
|
||||
|
||||
例: `1`, `18446744073709551615`, `0xDEADBEEF`, `01`, `0.1`, `1e100`, `-1e-100`, `inf`, `nan`.
|
||||
|
||||
### 字符串 {#syntax-string-literal}
|
||||
数字类型的值类型为能容纳该值的最小数据类型。
|
||||
例如：1 解析成 `UInt8`型，256 则解析成 `UInt16`。更多信息，参见 [数据类型](../sql-reference/data-types/index.md)
|
||||
|
||||
仅支持单引号中的字符串文字。 封闭的字符可以反斜杠转义。 以下转义序列具有相应的特殊值: `\b`, `\f`, `\r`, `\n`, `\t`, `\0`, `\a`, `\v`, `\xHH`. 在所有其他情况下，转义序列的格式为 `\c`，哪里 `c` 是任何字符，被转换为 `c`. 这意味着你可以使用序列 `\'`和`\\`. 该值将具有 [字符串](../sql-reference/data-types/string.md) 类型。
|
||||
例如: `1`, `18446744073709551615`, `0xDEADBEEF`, `01`, `0.1`, `1e100`, `-1e-100`, `inf`, `nan`.
|
||||
|
||||
在字符串文字中，你至少需要转义 `'` 和 `\`. 单引号可以用单引号，文字转义 `'It\'s'` 和 `'It''s'` 是平等的。
|
||||
### 字母 {#syntax-string-literal}
|
||||
CH只支持用单引号包含的字母。特殊字符可通过反斜杠进行转义。下列转义字符都有相应的实际值： `\b`, `\f`, `\r`, `\n`, `\t`, `\0`, `\a`, `\v`, `\xHH`。其它情况下，以 `\c`形式出现的转义字符，当`c`表示任意字符时，转义字符会转换成`c`。这意味着你可以使用 `\'`和`\\`。该值将拥有[String](../sql-reference/data-types/string.md)类型。
|
||||
|
||||
### 化合物 {#compound}
|
||||
|
||||
数组使用方括号构造 `[1, 2, 3]`. Nuples用圆括号构造 `(1, 'Hello, world!', 2)`.
|
||||
从技术上讲，这些不是文字，而是分别具有数组创建运算符和元组创建运算符的表达式。
|
||||
数组必须至少包含一个项目，元组必须至少包含两个项目。
|
||||
有一个单独的情况下，当元组出现在 `IN` a条款 `SELECT` 查询。 查询结果可以包含元组，但元组不能保存到数据库（除了具有以下内容的表 [记忆](../engines/table-engines/special/memory.md) 发动机）。
|
||||
在字符串中，你至少需要对 `'` 和 `\` 进行转义。单引号可以使用单引号转义，例如 `'It\'s'` 和 `'It''s'` 是相同的。
|
||||
|
||||
### NULL {#null-literal}
|
||||
### 括号 {#compound}
|
||||
数组都是使用方括号进行构造 `[1, 2, 3]`，元组则使用圆括号 `(1, 'Hello, world!', 2)`
|
||||
|
||||
指示该值丢失。
|
||||
从技术上来讲，这些都不是字符串，而是包含创建数组和元组运算符的表达式。
|
||||
|
||||
为了存储 `NULL` 在表字段中，它必须是 [可为空](../sql-reference/data-types/nullable.md) 类型。
|
||||
创建一个数组必须至少包含一个元素，创建一个元组至少包含2个元素
|
||||
|
||||
根据数据格式（输入或输出), `NULL` 可能有不同的表示。 有关详细信息，请参阅以下文档 [数据格式](../interfaces/formats.md#formats).
|
||||
当元组出现在 `SELECT` 查询的 `IN` 部分时，是一种例外情形。查询结果可以包含元组，但是元组类型不能保存到数据库中（除非表采用 [内存表](../engines/table-engines/special/memory.md)引擎）
|
||||
|
||||
处理有许多细微差别 `NULL`. 例如，如果比较操作的至少一个参数是 `NULL`，此操作的结果也是 `NULL`. 对于乘法，加法和其他操作也是如此。 有关详细信息，请阅读每个操作的文档。
|
||||
|
||||
在查询中，您可以检查 `NULL` 使用 [IS NULL](operators/index.md#operator-is-null) 和 [IS NOT NULL](operators/index.md) 运算符及相关功能 `isNull` 和 `isNotNull`.
|
||||
### NULL值 {#null-literal}
|
||||
|
||||
## 功能 {#functions}
|
||||
代表不存在的值
|
||||
|
||||
函数调用像一个标识符一样写入，并在圆括号中包含一个参数列表（可能是空的）。 与标准SQL相比，括号是必需的，即使是空的参数列表。 示例: `now()`.
|
||||
有常规函数和聚合函数（请参阅部分 “Aggregate functions”). 某些聚合函数可以包含括号中的两个参数列表。 示例: `quantile (0.9) (x)`. 这些聚合函数被调用 “parametric” 函数，并在第一个列表中的参数被调用 “parameters”. 不带参数的聚合函数的语法与常规函数的语法相同。
|
||||
为了能在表字段中存储NULL值，该字段必须声明为 [空值](../sql-reference/data-types/nullable.md) 类型
|
||||
根据数据的格式（输入或输出），NULL值有不同的表现形式。更多信息参见文档 [数据格式](../interfaces/formats.md#formats)
|
||||
|
||||
## 运营商 {#operators}
|
||||
在处理 `NULL`时存在很多细微差别。例如，比较运算的至少一个参数为 `NULL` ，该结果也是 `NULL` 。与之类似的还有乘法运算, 加法运算,以及其它运算。更多信息，请参阅每种运算的文档部分。
|
||||
|
||||
在查询解析过程中，运算符会转换为相应的函数，同时考虑它们的优先级和关联性。
|
||||
例如，表达式 `1 + 2 * 3 + 4` 转化为 `plus(plus(1, multiply(2, 3)), 4)`.
|
||||
在语句中，可以通过 [是否为NULL](operators/index.md#operator-is-null) 以及 [是否不为NULL](operators/index.md) 运算符，以及 `isNull` 、 `isNotNull` 函数来检查 `NULL` 值
|
||||
|
||||
## 数据类型和数据库表引擎 {#data_types-and-database-table-engines}
|
||||
## 函数 {#functions}
|
||||
函数调用的写法，类似于变量并带有被圆括号包含的参数列表（可能为空）。与标准SQL不同，圆括号是必须的，不管参数列表是否为空。例如： `now()`。
|
||||
|
||||
数据类型和表引擎 `CREATE` 查询的编写方式与标识符或函数相同。 换句话说，它们可能包含也可能不包含括号中的参数列表。 有关详细信息，请参阅部分 “Data types,” “Table engines,” 和 “CREATE”.
|
||||
函数分为常规函数和聚合函数（参见“Aggregate functions”一章）。有些聚合函数包含2个参数列表，第一个参数列表中的参数被称为“parameters”。不包含“parameters”的聚合函数语法和常规函数是一样的。
|
||||
|
||||
|
||||
## 运算符 {#operators}
|
||||
|
||||
在查询解析阶段，运算符会被转换成对应的函数，使用时请注意它们的优先级。例如：
|
||||
表达式 `1 + 2 * 3 + 4` 会被解析成 `plus(plus(1, multiply(2, 3)), 4)`.
|
||||
|
||||
|
||||
## 数据类型及数据库/表引擎 {#data_types-and-database-table-engines}
|
||||
|
||||
`CREATE` 语句中的数据类型和表引擎写法与变量或函数类似。
|
||||
换句话说，它们可以用括号包含参数列表。更多信息，参见“数据类型,” “数据表引擎” 和 “CREATE语句”等章节
|
||||
|
||||
## 表达式别名 {#syntax-expression_aliases}
|
||||
|
||||
别名是查询中表达式的用户定义名称。
|
||||
别名是用户对表达式的自定义名称
|
||||
|
||||
``` sql
|
||||
expr AS alias
|
||||
```
|
||||
|
||||
- `AS` — The keyword for defining aliases. You can define the alias for a table name or a column name in a `SELECT` 子句不使用 `AS` 关键字。
|
||||
- `AS` — 用于定义别名的关键字。可以对表或select语句中的列定义别名(`AS` 可以省略）
|
||||
例如, `SELECT table_name_alias.column_name FROM table_name table_name_alias`.
|
||||
|
||||
For example, `SELECT table_name_alias.column_name FROM table_name table_name_alias`.
|
||||
在 [CAST函数](sql_reference/functions/type_conversion_functions.md#type_conversion_function-cast) 中，`AS`有其它含义。请参见该函数的说明部分。
|
||||
|
||||
In the [CAST](sql_reference/functions/type_conversion_functions.md#type_conversion_function-cast) function, the `AS` keyword has another meaning. See the description of the function.
|
||||
|
||||
- `expr` — Any expression supported by ClickHouse.
|
||||
- `expr` — 任意CH支持的表达式.
|
||||
|
||||
For example, `SELECT column_name * 2 AS double FROM some_table`.
|
||||
例如, `SELECT column_name * 2 AS double FROM some_table`.
|
||||
|
||||
- `alias` — Name for `expr`. 别名应符合 [标识符](#syntax-identifiers) 语法
|
||||
- `alias` — `expr` 的名称。别名必须符合 [变量名]](#syntax-identifiers) 语法.
|
||||
|
||||
For example, `SELECT "table t".column_name FROM table_name AS "table t"`.
|
||||
例如, `SELECT "table t".column_name FROM table_name AS "table t"`.
|
||||
|
||||
### 使用注意事项 {#notes-on-usage}
|
||||
### 用法注意 {#notes-on-usage}
|
||||
|
||||
别名对于查询或子查询是全局的，您可以在查询的任何部分中为任何表达式定义别名。 例如, `SELECT (1 AS n) + 2, n`.
|
||||
别名在当前查询或子查询中是全局可见的，你可以在查询语句的任何位置对表达式定义别名
|
||||
|
||||
别名在子查询和子查询之间不可见。 例如，在执行查询时 `SELECT (SELECT sum(b.a) + num FROM b) - a.a AS num FROM a` ClickHouse生成异常 `Unknown identifier: num`.
|
||||
别名在当前查询的子查询及不同子查询中是不可见的。例如，执行如下查询SQL: `SELECT (SELECT sum(b.a) + num FROM b) - a.a AS num FROM a` ,CH会提示异常 `Unknown identifier: num`.
|
||||
|
||||
如果为结果列定义了别名 `SELECT` 子查询的子句，这些列在外部查询中可见。 例如, `SELECT n + m FROM (SELECT 1 AS n, 2 AS m)`.
|
||||
|
||||
小心使用与列或表名相同的别名。 让我们考虑以下示例:
|
||||
如果给select子查询语句的结果列定义其别名，那么在外层可以使用该别名。例如, `SELECT n + m FROM (SELECT 1 AS n, 2 AS m)`.
|
||||
|
||||
注意列的别名和表的别名相同时的情形，考虑如下示例：
|
||||
``` sql
|
||||
CREATE TABLE t
|
||||
(
|
||||
@ -172,16 +178,18 @@ Received exception from server (version 18.14.17):
|
||||
Code: 184. DB::Exception: Received from localhost:9000, 127.0.0.1. DB::Exception: Aggregate function sum(b) is found inside another aggregate function in query.
|
||||
```
|
||||
|
||||
在这个例子中，我们声明表 `t` 带柱 `b`. 然后，在选择数据时，我们定义了 `sum(b) AS b` 别名 由于别名是全局的，ClickHouse替换了文字 `b` 在表达式中 `argMax(a, b)` 用表达式 `sum(b)`. 这种替换导致异常。
|
||||
在这个示例中，先声明了表 `t` 以及列 `b`。然后，在查询数据时，又定义了别名 `sum(b) AS b`。由于别名是全局的，CH使用表达式 `sum(b)` 来替换表达式 `argMax(a, b)` 中的变量 `b`。这种替换导致出现异常。
|
||||
|
||||
## 星号 {#asterisk}
|
||||
|
||||
在一个 `SELECT` 查询中，星号可以替换表达式。 有关详细信息，请参阅部分 “SELECT”.
|
||||
select查询中，星号可以代替表达式使用。详情请参见“select”部分
|
||||
|
||||
|
||||
## 表达式 {#syntax-expressions}
|
||||
|
||||
表达式是函数、标识符、文字、运算符的应用程序、括号中的表达式、子查询或星号。 它还可以包含别名。
|
||||
表达式列表是一个或多个用逗号分隔的表达式。
|
||||
函数和运算符，反过来，可以有表达式作为参数。

An expression is a function, identifier, literal, application of an operator, expression in brackets, subquery, or asterisk. It can also contain an alias.
|
||||
A list of expressions is one or more expressions separated by commas.
|
||||
Functions and operators, in turn, can have expressions as arguments.
