|
||||
3. After entering the password, you will get prompted the MySQL connection string for this service
|
||||
|
||||
|
||||
## Creating multiple MySQL users in ClickHouse Cloud
|
||||
|
||||
By default, there is a built-in `mysql4<subdomain>` user, which uses the same password as the `default` one. The `<subdomain>` part is the first segment of your ClickHouse Cloud hostname. This format is necessary to work with the tools that implement secure connection, but don't provide [SNI information in their TLS handshake](https://www.cloudflare.com/learning/ssl/what-is-sni), which makes it impossible to do the internal routing without an extra hint in the username (MySQL console client is one of such tools).
|
||||
|
||||
Because of this, we _highly recommend_ following the `mysql4<subdomain>_<username>` format when creating a new user intended to be used with the MySQL interface, where `<subdomain>` is a hint to identify your Cloud service, and `<username>` is an arbitrary suffix of your choice.
|
||||
|
||||
:::tip
|
||||
For ClickHouse Cloud hostname like `foobar.us-east1.aws.clickhouse.cloud`, the `<subdomain>` part equals to `foobar`, and a custom MySQL username could look like `mysql4foobar_team1`.
|
||||
:::
|
||||
|
||||
You can create extra users to use with the MySQL interface if, for example, you need to apply extra settings.
|
||||
|
||||
1. Optional - create a [settings profile](https://clickhouse.com/docs/en/sql-reference/statements/create/settings-profile) to apply for your custom user. For example, `my_custom_profile` with an extra setting which will be applied by default when we connect with the user we create later:
|
||||
|
||||
```sql
|
||||
CREATE SETTINGS PROFILE my_custom_profile SETTINGS prefer_column_name_to_alias=1;
|
||||
```
|
||||
|
||||
`prefer_column_name_to_alias` is used just as an example, you can use other settings there.
|
||||
2. [Create a user](https://clickhouse.com/docs/en/sql-reference/statements/create/user) using the following format: `mysql4<subdomain>_<username>` ([see above](#creating-multiple-mysql-users-in-clickhouse-cloud)). The password must be in double SHA1 format. For example:
|
||||
|
||||
```sql
|
||||
CREATE USER mysql4foobar_team1 IDENTIFIED WITH double_sha1_password BY 'YourPassword42$';
|
||||
```
|
||||
|
||||
or if you want to use a custom profile for this user:
|
||||
|
||||
```sql
|
||||
CREATE USER mysql4foobar_team1 IDENTIFIED WITH double_sha1_password BY 'YourPassword42$' SETTINGS PROFILE 'my_custom_profile';
|
||||
```
|
||||
|
||||
where `my_custom_profile` is the name of the profile you created earlier.
|
||||
3. [Grant](https://clickhouse.com/docs/en/sql-reference/statements/grant) the new user the necessary permissions to interact with the desired tables or databases. For example, if you want to grant access to `system.query_log` only:
|
||||
|
||||
```sql
|
||||
GRANT SELECT ON system.query_log TO mysql4foobar_team1;
|
||||
```
|
||||
|
||||
4. Use the created user to connect to your ClickHouse Cloud service with the MySQL interface.
|
||||
|
||||
### Troubleshooting multiple MySQL users in ClickHouse Cloud
|
||||
|
||||
If you created a new MySQL user, and you see the following error while connecting via MySQL CLI client:
|
||||
|
||||
```
|
||||
ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 54
|
||||
```
|
||||
|
||||
In this case, ensure that the username follows the `mysql4<subdomain>_<username>` format, as described ([above](#creating-multiple-mysql-users-in-clickhouse-cloud)).
|
||||
|
||||
## Enabling the MySQL Interface On Self-managed ClickHouse
|
||||
|
||||
Add the [mysql_port](../operations/server-configuration-parameters/settings.md#server_configuration_parameters-mysql_port) setting to your server's configuration file. For example, you could define the port in a new XML file in your `config.d/` [folder](../operations/configuration-files):

|

Calculates a concatenated string from a group of strings, optionally separated by a delimiter, and optionally limited by a maximum number of elements.
|
||||
|
||||
**Syntax**
|
||||
|
||||
``` sql
|
||||
groupConcat(expression [, delimiter] [, limit]);
|
||||
```
|
||||
|
||||
**Arguments**
|
||||
|
||||
- `expression` — The expression or column name that outputs strings to be concatenated..
|
||||
- `delimiter` — A [string](../../../sql-reference/data-types/string.md) that will be used to separate concatenated values. This parameter is optional and defaults to an empty string if not specified.
|
||||
- `limit` — A positive [integer](../../../sql-reference/data-types/int-uint.md) specifying the maximum number of elements to concatenate. If more elements are present, excess elements are ignored. This parameter is optional.
|
||||
|
||||
:::note
|
||||
If delimiter is specified without limit, it must be the first parameter following the expression. If both delimiter and limit are specified, delimiter must precede limit.
|
||||
:::
|
||||
|
||||
**Returned value**
|
||||
|
||||
- Returns a [string](../../../sql-reference/data-types/string.md) consisting of the concatenated values of the column or expression. If the group has no elements or only null elements, and the function does not specify a handling for only null values, the result is a nullable string with a null value.
|
||||
|
||||
**Examples**
|
||||
|
||||
Input table:
|
||||
|
||||
``` text
|
||||
┌─id─┬─name─┐
|
||||
│ 1 │ John│
|
||||
│ 2 │ Jane│
|
||||
│ 3 │ Bob│
|
||||
└────┴──────┘
|
||||
```
|
||||
|
||||
1. Basic usage without a delimiter:
|
||||
|
||||
Query:
|
||||
|
||||
``` sql
|
||||
SELECT groupConcat(Name) FROM Employees;
|
||||
```
|
||||
|
||||
Result:
|
||||
|
||||
``` text
|
||||
JohnJaneBob
|
||||
```
|
||||
|
||||
This concatenates all names into one continuous string without any separator.
|
||||
|
||||
|
||||
2. Using comma as a delimiter:
|
||||
|
||||
Query:
|
||||
|
||||
``` sql
|
||||
SELECT groupConcat(Name, ', ', 2) FROM Employees;
|
||||
```
|
||||
|
||||
Result:
|
||||
|
||||
``` text
|
||||
John, Jane, Bob
|
||||
```
|
||||
|
||||
This output shows the names separated by a comma followed by a space.
|
||||
|
||||
|
||||
3. Limiting the number of concatenated elements
|
||||
|
||||
Query:
|
||||
|
||||
``` sql
|
||||
SELECT groupConcat(Name, ', ', 2) FROM Employees;
|
||||
```
|
||||
|
||||
Result:
|
||||
|
||||
``` text
|
||||
John, Jane
|
||||
```
|
||||
|
||||
This query limits the output to the first two names, even though there are more names in the table.

Imagine a square, one side of which is a x-axis, other is a y-axis.
|
||||
First approximation of the Hilbert curve is on the picture - U curve.
|
||||
So we divide Hilbert Code Interval on 4 parts each of which is represented by a square
|
||||
and look where the given interval [start, finish] is located:
|
||||
[00xxxxxx | 01xxxxxx | 10xxxxxx | 11xxxxxx ]
|
||||
1: [ ]
|
||||
start = 0010111 end = 10111110
|
||||
2: [ ] [ ]
|
||||
If it contains a whole sector (that represents a domain=square),
|
||||
then we take this range. In the example above - it is a sector [01000000, 01111111]
|
||||
Then we dig into the recursion and check the remaining ranges.
|
||||
Note that after the first call all other ranges in the recursion will have either start or finish on the end of a range,
|
||||
so the complexity of the algorithm will be O(logN), where N is the maximum of hilbert code.
