# Select Database

Ushbu bo'limda bizda mavjud bo'lgan database'ga ulanish(tanlash) ni ko'rib chiqamiz.

PostgreSQL'da database'ga ulanishni 2 xil usuli mavjud:

* pgAdmin yordamida ulanish
* SQL terminali yordamida ulanish

#### Keling, birinchi pgAdmin orqali bizda mavjud bo'lgan database'ga ulanishni ko'rib chiqamiz:

Yuqoridagi ketma-ketlikni bajarganingizdan so'ng, siz o'zingiz tanlagan database'ga ulanasiz.

Ulanishingiz bilan sizga yangi oyna paydo bo'ladi va bu yerda siz SQL querylarini yozishingiz mumkin.

#### Endi esa ikkinchi yo'l, SQL terminali orqali database'ga ulanishni ko'rib chiqamiz:

SQL terminalini ochamiz va unga **'\l'** buyrug'ini kiritish orqali bizda mavjud database'lar ro'yxati ko'rishimiz mumkin:

Database'ga ulanish uchun '\c' buyrug'idan foydalanamiz:

Quyida biz 'dotnetuz' database'ga ulanamiz.

```
postgres=# \c dotnetuz
```
