### Compatibility
|
||||
|
||||
- The amd64 image requires support for [SSE3 instructions](https://en.wikipedia.org/wiki/SSE3). Virtually all x86 CPUs after 2005 support SSE3.
|
||||
- The arm64 image requires support for the [ARMv8.2-A architecture](https://en.wikipedia.org/wiki/AArch64#ARMv8.2-A) and additionally the Load-Acquire RCpc register. The register is optional in version ARMv8.2-A and mandatory in [ARMv8.3-A](https://en.wikipedia.org/wiki/AArch64#ARMv8.3-A). Supported in Graviton >=2, Azure and GCP instances. Examples for unsupported devices are Raspberry Pi 4 (ARMv8.0-A) and Jetson AGX Xavier/Orin (ARMv8.2-A).

## How to extend this image
|
||||
|
||||
To perform additional initialization in an image derived from this one, add one or more `*.sql`, `*.sql.gz`, or `*.sh` scripts under `/docker-entrypoint-initdb.d`. After the entrypoint calls `initdb`, it will run any `*.sql` files, run any executable `*.sh` scripts, and source any non-executable `*.sh` scripts found in that directory to do further initialization before starting the service.

As of writing (2023/3/10) building for s390x considered to be experimental. Not all features can be enabled, has broken features and is currently under active development.
|
||||
At the time of writing (2024 May), support for the s390x platform is considered experimental, i.e. some features are disabled or broken on s390x.

## Building ClickHouse for s390x
|
||||
|
||||
## Building
|
||||
|
||||
s390x has two OpenSSL-related build options.
|
||||
- By default, the s390x build will dynamically link to OpenSSL libraries. It will build OpenSSL shared objects, so it's not necessary to install OpenSSL beforehand. (This option is recommended in all cases.)
|
||||
- Another option is to build OpenSSL in-tree. In this case two build flags need to be supplied to cmake
|
||||
```bash
|
||||
-DENABLE_OPENSSL_DYNAMIC=0
|
||||
```

s390x has two OpenSSL-related build options:
|
||||
- By default, OpenSSL is build on s390x as a shared library. This is different from all other platforms, where OpenSSL is build as static library.
|
||||
- To build OpenSSL as a static library regardless, pass `-DENABLE_OPENSSL_DYNAMIC=0` to CMake.

**Implementation details**
|

|
||||
In some cases, you can rely on the order of execution. This applies to cases when `SELECT` comes from a subquery that uses `ORDER BY`.
|
||||
|
||||
When a `SELECT` query has the `GROUP BY` clause or at least one aggregate function, ClickHouse (in contrast to MySQL) requires that all expressions in the `SELECT`, `HAVING`, and `ORDER BY` clauses be calculated from keys or from aggregate functions. In other words, each column selected from the table must be used either in keys or inside aggregate functions. To get behavior like in MySQL, you can put the other columns in the `any` aggregate function.

||||
|
||||
**Returned values**
|

Named subqueries can be included to the current and child query context in places where table objects are allowed. Recursion is prevented by hiding the current level CTEs from the WITH expression.

||||

## Recursive Queries
|
||||
|
||||
The optional RECURSIVE modifier allows for a WITH query to refer to its own output. Example:
|
||||
|
||||
**Example:** Sum integers from 1 through 100
|
||||
|
||||
```sql
|
||||
WITH RECURSIVE test_table AS (
|
||||
SELECT 1 AS number
|
||||
UNION ALL
|
||||
SELECT number + 1 FROM test_table WHERE number < 100
|
||||
)
|
||||
SELECT sum(number) FROM test_table;
|
||||
```
|
||||
|
||||
``` text
|
||||
┌─sum(number)─┐
|
||||
│ 5050 │
|
||||
└─────────────┘
|
||||
```
|
||||
|
||||
The general form of a recursive `WITH` query is always a non-recursive term, then `UNION ALL`, then a recursive term, where only the recursive term can contain a reference to the query's own output. Recursive CTE query is executed as follows:
|
||||
|
||||
1. Evaluate the non-recursive term. Place result of non-recursive term query in a temporary working table.
|
||||
2. As long as the working table is not empty, repeat these steps:
|
||||
1. Evaluate the recursive term, substituting the current contents of the working table for the recursive self-reference. Place result of recursive term query in a temporary intermediate table.
|
||||
2. Replace the contents of the working table with the contents of the intermediate table, then empty the intermediate table.
|
||||
|
||||
Recursive queries are typically used to work with hierarchical or tree-structured data. For example, we can write a query that performs tree traversal:
|
||||
|
||||
**Example:** Tree traversal
|
||||
|
||||
First let's create tree table:
|
||||
|
||||
```sql
|
||||
DROP TABLE IF EXISTS tree;
|
||||
CREATE TABLE tree
|
||||
(
|
||||
id UInt64,
|
||||
parent_id Nullable(UInt64),
|
||||
data String
|
||||
) ENGINE = MergeTree ORDER BY id;
|
||||
|
||||
INSERT INTO tree VALUES (0, NULL, 'ROOT'), (1, 0, 'Child_1'), (2, 0, 'Child_2'), (3, 1, 'Child_1_1');
|
||||
```
|
||||
|
||||
We can traverse those tree with such query:
|
||||
|
||||
**Example:** Tree traversal
|
||||
```sql
|
||||
WITH RECURSIVE search_tree AS (
|
||||
SELECT id, parent_id, data
|
||||
FROM tree t
|
||||
WHERE t.id = 0
|
||||
UNION ALL
|
||||
SELECT t.id, t.parent_id, t.data
|
||||
FROM tree t, search_tree st
|
||||
WHERE t.parent_id = st.id
|
||||
)
|
||||
SELECT * FROM search_tree;
|
||||
```
|
||||
|
||||
```text
|
||||
┌─id─┬─parent_id─┬─data──────┐
|
||||
│ 0 │ ᴺᵁᴸᴸ │ ROOT │
|
||||
│ 1 │ 0 │ Child_1 │
|
||||
│ 2 │ 0 │ Child_2 │
|
||||
│ 3 │ 1 │ Child_1_1 │
|
||||
└────┴───────────┴───────────┘
|
||||
```
|
||||
|
||||
### Search order
|
||||
|
||||
To create a depth-first order, we compute for each result row an array of rows that we have already visited:
|
||||
|
||||
**Example:** Tree traversal depth-first order
|
||||
```sql
|
||||
WITH RECURSIVE search_tree AS (
|
||||
SELECT id, parent_id, data, [t.id] AS path
|
||||
FROM tree t
|
||||
WHERE t.id = 0
|
||||
UNION ALL
|
||||
SELECT t.id, t.parent_id, t.data, arrayConcat(path, [t.id])
|
||||
FROM tree t, search_tree st
|
||||
WHERE t.parent_id = st.id
|
||||
)
|
||||
SELECT * FROM search_tree ORDER BY path;
|
||||
```
|
||||
|
||||
```text
|
||||
┌─id─┬─parent_id─┬─data──────┬─path────┐
|
||||
│ 0 │ ᴺᵁᴸᴸ │ ROOT │ [0] │
|
||||
│ 1 │ 0 │ Child_1 │ [0,1] │
|
||||
│ 3 │ 1 │ Child_1_1 │ [0,1,3] │
|
||||
│ 2 │ 0 │ Child_2 │ [0,2] │
|
||||
└────┴───────────┴───────────┴─────────┘
|
||||
```
|
||||
|
||||
To create a breadth-first order, standard approach is to add column that tracks the depth of the search:
|
||||
|
||||
**Example:** Tree traversal breadth-first order
|
||||
```sql
|
||||
WITH RECURSIVE search_tree AS (
|
||||
SELECT id, parent_id, data, [t.id] AS path, toUInt64(0) AS depth
|
||||
FROM tree t
|
||||
WHERE t.id = 0
|
||||
UNION ALL
|
||||
SELECT t.id, t.parent_id, t.data, arrayConcat(path, [t.id]), depth + 1
|
||||
FROM tree t, search_tree st
|
||||
WHERE t.parent_id = st.id
|
||||
)
|
||||
SELECT * FROM search_tree ORDER BY depth;
|
||||
```
|
||||
|
||||
```text
|
||||
┌─id─┬─link─┬─data──────┬─path────┬─depth─┐
|
||||
│ 0 │ ᴺᵁᴸᴸ │ ROOT │ [0] │ 0 │
|
||||
│ 1 │ 0 │ Child_1 │ [0,1] │ 1 │
|
||||
│ 2 │ 0 │ Child_2 │ [0,2] │ 1 │
|
||||
│ 3 │ 1 │ Child_1_1 │ [0,1,3] │ 2 │
|
||||
└────┴──────┴───────────┴─────────┴───────┘
|
||||
```
|
||||
|
||||
### Cycle detection
|
||||
|
||||
First let's create graph table:
|
||||
|
||||
```sql
|
||||
DROP TABLE IF EXISTS graph;
|
||||
CREATE TABLE graph
|
||||
(
|
||||
from UInt64,
|
||||
to UInt64,
|
||||
label String
|
||||
) ENGINE = MergeTree ORDER BY (from, to);
|
||||
|
||||
INSERT INTO graph VALUES (1, 2, '1 -> 2'), (1, 3, '1 -> 3'), (2, 3, '2 -> 3'), (1, 4, '1 -> 4'), (4, 5, '4 -> 5');
|
||||
```
|
||||
|
||||
We can traverse that graph with such query:
|
||||
|
||||
**Example:** Graph traversal without cycle detection
|
||||
```sql
|
||||
WITH RECURSIVE search_graph AS (
|
||||
SELECT from, to, label FROM graph g
|
||||
UNION ALL
|
||||
SELECT g.from, g.to, g.label
|
||||
FROM graph g, search_graph sg
|
||||
WHERE g.from = sg.to
|
||||
)
|
||||
SELECT DISTINCT * FROM search_graph ORDER BY from;
|
||||
```
|
||||
```text
|
||||
┌─from─┬─to─┬─label──┐
|
||||
│ 1 │ 4 │ 1 -> 4 │
|
||||
│ 1 │ 2 │ 1 -> 2 │
|
||||
│ 1 │ 3 │ 1 -> 3 │
|
||||
│ 2 │ 3 │ 2 -> 3 │
|
||||
│ 4 │ 5 │ 4 -> 5 │
|
||||
└──────┴────┴────────┘
|
||||
```
|
||||
|
||||
But if we add cycle in that graph, previous query will fail with `Maximum recursive CTE evaluation depth` error:
|
||||
|
||||
```sql
|
||||
INSERT INTO graph VALUES (5, 1, '5 -> 1');
|
||||
|
||||
WITH RECURSIVE search_graph AS (
|
||||
SELECT from, to, label FROM graph g
|
||||
UNION ALL
|
||||
SELECT g.from, g.to, g.label
|
||||
FROM graph g, search_graph sg
|
||||
WHERE g.from = sg.to
|
||||
)
|
||||
SELECT DISTINCT * FROM search_graph ORDER BY from;
|
||||
```
|
||||
|
||||
```text

||||

Consider raising max_recursive_cte_evaluation_depth setting.: While executing RecursiveCTESource. (TOO_DEEP_RECURSION)
|
||||
```
|
||||
|
||||
The standard method for handling cycles is to compute an array of the already visited nodes:
|
||||
|
||||
**Example:** Graph traversal with cycle detection
|
||||
```sql
|
||||
WITH RECURSIVE search_graph AS (
|
||||
SELECT from, to, label, false AS is_cycle, [tuple(g.from, g.to)] AS path FROM graph g
|
||||
UNION ALL
|
||||
SELECT g.from, g.to, g.label, has(path, tuple(g.from, g.to)), arrayConcat(sg.path, [tuple(g.from, g.to)])
|
||||
FROM graph g, search_graph sg
|
||||
WHERE g.from = sg.to AND NOT is_cycle
|
||||
)
|
||||
SELECT * FROM search_graph WHERE is_cycle ORDER BY from;
|
||||
```
|
||||
|
||||
```text
|
||||
┌─from─┬─to─┬─label──┬─is_cycle─┬─path──────────────────────┐
|
||||

### Infinite queries

||||

||||

||||

**Example:** Infinite recursive CTE query
|
||||
```sql
|
||||

|
||||
SELECT 1 AS number
|
||||
UNION ALL
|
||||
SELECT number + 1 FROM test_table
|
||||
)
|
||||
SELECT sum(number) FROM (SELECT number FROM test_table LIMIT 100);

|
||||
```
|
||||
|
||||
**Аргументы**
|
||||

## coalesce {#coalesce}
|
||||
|
||||
Последовательно слева-направо проверяет являются ли переданные аргументы `NULL` и возвращает первый не `NULL`.
|
||||
|
||||

coalesce(x,...)
|
||||
```
|
||||
|
||||
**Аргументы**
|
||||
|
||||
- Произвольное количество параметров не составного типа. Все параметры должны быть совместимы по типу данных.
|
||||
|
||||
**Возвращаемые значения**
|
||||
|
||||
- Первый не `NULL` аргумент.
|
||||
- `NULL`, если все аргументы — `NULL`.
|
||||
|
||||
**Пример**
|
||||
|
||||
Рассмотрим адресную книгу, в которой может быть указано несколько способов связи с клиентом.
|
||||
|
||||
``` text
|
||||
┌─name─────┬─mail─┬─phone─────┬──icq─┐
|
||||
│ client 1 │ ᴺᵁᴸᴸ │ 123-45-67 │ 123 │
|
||||

|
||||
└──────────┴──────┴───────────┴──────┘
|
||||
```
|
||||
|
||||
Поля `mail` и `phone` имеют тип String, а поле `icq` — `UInt32`, его необходимо будет преобразовать в `String`.
|
||||
|
||||
Получим из адресной книги первый доступный способ связаться с клиентом:
|
||||
|
||||
``` sql
|
||||
SELECT coalesce(mail, phone, CAST(icq,'Nullable(String)')) FROM aBook;
|
||||
```
|
||||

└──────────┴──────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
## ifNull {#ifnull}
|
||||
|
||||
Возвращает альтернативное значение, если основной аргумент — `NULL`.
|
||||
|
||||
``` sql
|
||||
ifNull(x,alt)
|
||||
```
|
||||
|
||||
**Аргументы**
|
||||
|
||||
- `x` — значение для проверки на `NULL`,
|
||||
- `alt` — значение, которое функция вернёт, если `x` — `NULL`.
|
||||
|
||||
**Возвращаемые значения**
|
||||
|
||||
- Значение `x`, если `x` — не `NULL`.
|
||||
- Значение `alt`, если `x` — `NULL`.
|
||||
|
||||

|
||||
## nullIf {#nullif}
|
||||
|
||||
Возвращает `NULL`, если аргументы равны.
|
||||
|
||||
``` sql
|
||||
nullIf(x, y)
|
||||
```
|
||||
|
||||
**Аргументы**
|
||||
|
||||
`x`, `y` — значения для сравнивания. Они должны быть совместимых типов, иначе ClickHouse сгенерирует исключение.
|
||||
|
||||
**Возвращаемые значения**
|
||||
|
||||
- `NULL`, если аргументы равны.
|
||||

||||
``` sql
|
||||
assumeNotNull(x)
|
||||
```
|
||||
|
||||
**Аргументы**
|
||||
|
||||
- `x` — исходное значение.
|
||||
|
||||
**Возвращаемые значения**
|
||||
|
||||
- Исходное значение с не `Nullable` типом, если оно — не `NULL`.
|
||||
- Неспецифицированный результат, зависящий от реализации, если исходное значение — `NULL`.
|
||||
|
||||
