## Base58Decode(plaintext[, alphabet_name])
|
||||||
|
|
||||||
|
Accepts a String and encodes/decodes it using [Base58](https://tools.ietf.org/id/draft-msporny-base58-01.html) encoding scheme using specified alphabet.
|
||||||
|
|
||||||
|
**Syntax**
|
||||||
|
|
||||||
|
```sql
|
||||||
|
base58Encode(decoded[, alphabet_name])
|
||||||
|
base58Decode(encoded[, alphabet_name])
|
||||||
|
```
|
||||||
|
|
||||||
|
**Arguments**
|
||||||
|
|
||||||
|
- `decoded` — [String](../../sql-reference/data-types/string.md) column or constant.
|
||||||
|
- `encoded` — [String](../../sql-reference/data-types/string.md) column or constant. If the string is not a valid base58-encoded value, `1001 Exception` will be thrown.
|
||||||
|
- `alphabet_name` — String constant. Specifies alphabet used for encoding. Possible values: `gmp`, `bitcoin`, `ripple`, `flickr`. Default: `gmp`.
|
||||||
|
|
||||||
|
**Returned value**
|
||||||
|
|
||||||
|
- A string containing encoded/decoded value of 1st argument.
|
||||||
|
|
||||||
|
Type: [String](../../sql-reference/data-types/string.md).
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
Query:
|
||||||
|
|
||||||
|
``` sql

Принимает на вход строку или колонку строк и кодирует/раскодирует их с помощью схемы кодирования [Base58](https://tools.ietf.org/id/draft-msporny-base58-01.html) с использованием указанного алфавита.
|
||||||
|
|
||||||
|
**Синтаксис**
|
||||||
|
|
||||||
|
```sql
|
||||||
|
base58Encode(decoded[, alphabet_name])
|
||||||
|
base58Decode(encoded[, alphabet_name])
|
||||||
|
```
|
||||||
|
|
||||||
|
**Аргументы**
|
||||||
|
|
||||||
|
- `decoded` — Колонка или строка типа [String](../../sql-reference/data-types/string.md).
|
||||||
|
- `encoded` — Колонка или строка типа [String](../../sql-reference/data-types/string.md). Если входная строка не является корректным кодом для какой-либо другой строки, возникнет исключение `1001`.
|
||||||
|
- `alphabet_name` — Строковая константа. Указывает алфавит, для которого необходимо получить код. Может принимать одно из следующих значений: `gmp`, `bitcoin`, `ripple`, `flickr`. По умолчанию: `gmp`.
|
||||||
|
|
||||||
|
**Возвращаемое значение**
|
||||||
|
|
||||||
|
- Строка, содержащая раскодированный/закодированный первый аргумент.
|
||||||
|
|
||||||
|
Тип: [String](../../sql-reference/data-types/string.md).
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
Запрос:
|
||||||
|
|
||||||
|
``` sql
