Snowflake - Database

A database is a logical grouping of schemas where tables and columns resides. In this chapter, we will discuss about how to create a database, and view details.

Snowflake provides the user two ways to create a database, first way is by using user interface and the second way is by applying SQL query.

View Databases

To view all the listed warehouses, user can use the following SQL. It brings the details of all listed warehouses.


To clone a database, user can use the following SQL, here “TEST_DB_3” is a new database named while DEMO_DB is used to clone it −


To delete database, use the following SQL −


User can run SHOW DATABSE query after each operation to verify whether operation is completed.
