# Generaterandom {#table_engines-generate}
|
||
|
||
GenerateRandom tablo motoru, verilen tablo şeması için rasgele veri üretir.
|
||
|
||
Kullanım örnekleri:
|
||
|
||
- Tekrarlanabilir büyük tabloyu doldurmak için testte kullanın.
|
||
- Fuzzing testleri için rastgele girdi oluşturun.
|
||
|
||
## ClickHouse sunucusunda kullanım {#usage-in-clickhouse-server}
|
||
|
||
``` sql
|
||
ENGINE = GenerateRandom(random_seed, max_string_length, max_array_length)
|
||
```
|
||
|
||
Bu `max_array_length` ve `max_string_length` parametreler tüm maksimum uzunluğu belirtin
|
||
oluşturulan verilerde dizi sütunları ve dizeleri.
|
||
|
||
Tablo motoru oluşturmak yalnızca destekler `SELECT` sorgular.
|
||
|
||
Tüm destekler [Veri türleri](../../../sql-reference/data-types/index.md) dışında bir tabloda saklanabilir `LowCardinality` ve `AggregateFunction`.
|
||
|
||
**Örnek:**
|
||
|
||
**1.** Set up the `generate_engine_table` Tablo:
|
||
|
||
``` sql
|
||
CREATE TABLE generate_engine_table (name String, value UInt32) ENGINE = GenerateRandom(1, 5, 3)
|
||
```
|
||
|
||
**2.** Verileri sorgula:
|
||
|
||
``` sql
|
||
SELECT * FROM generate_engine_table LIMIT 3
|
||
```
|
||
|
||
``` text
|
||
┌─name─┬──────value─┐
|
||
│ c4xJ │ 1412771199 │
|
||
│ r │ 1791099446 │
|
||
│ 7#$ │ 124312908 │
|
||
└──────┴────────────┘
|
||
```
