Complete the code to create a new Snowflake user with a password.

Snowflake

CREATE USER new_user PASSWORD = '[1]';

Drag options to blanks, or click blank then click option'

A'MySecurePass123!'

Bnew_password

Cpassword123

D'12345'

💡 Hint

Common Mistakes

Not enclosing the password in single quotes

Using a weak password that Snowflake rejects

The password must be a string enclosed in single quotes and follow Snowflake's password policy. 'MySecurePass123!' is a valid example.

💡 Hint

Common Mistakes

Using a different warehouse name than intended

Omitting the warehouse name

The warehouse name must match the intended name exactly. Here, 'compute_wh' is the correct warehouse name.

Fix the error in the command to create a database named 'sales_db'.

Snowflake

CREATE DATABASE [1];

Drag options to blanks, or click blank then click option'

A'sales_db'

Bsales db

Csales_db

Dsales-db

Attempts:

💡 Hint

Common Mistakes

Using single quotes around the database name

Including spaces or hyphens in the name

Database names should not be enclosed in quotes unless using double quotes for case sensitivity. Using sales_db without quotes is correct.

4fill in blank

hard

Fill both blanks to grant the role 'analyst' access to the 'sales_db' database.

Snowflake

GRANT [1] ON DATABASE [2] TO ROLE analyst;

Drag options to blanks, or click blank then click option'

BSELECT

Csales_db

Dsales

💡 Hint

Common Mistakes

Granting SELECT on the database (SELECT is for tables)

Using incorrect database name

To allow a role to use a database, the USAGE privilege is granted on the database name 'sales_db'.

5fill in blank

hard

Fill all three blanks to create a Snowflake role 'data_engineer' and grant it to user 'new_user'.

Snowflake

CREATE ROLE [1]; GRANT ROLE [2] TO USER [3];

Drag options to blanks, or click blank then click option'

Adata_engineer

Cnew_user

Dadmin

Attempts:

💡 Hint

Common Mistakes

Using different role names in create and grant commands

Granting role to wrong user

The role 'data_engineer' is created and then granted to the user 'new_user'. Both blanks for the role name must match exactly.

Practice

1. What is the first step to start using Snowflake for data storage and analysis?

easy

A. Sign up on the Snowflake website to create an account

B. Write SQL queries to create tables

C. Install Snowflake software on your computer

D. Create a virtual machine in the cloud

Solution

1. Step 1: Understand Snowflake account creation

   Before using Snowflake, you must have an account created by signing up on their website.

2. Step 2: Recognize account as the starting point

   Without an account, you cannot access Snowflake services or create warehouses and databases.

3. Final Answer:

   Sign up on the Snowflake website to create an account -> Option A

4. Quick Check:

   First step = Sign up [OK]

Hint: Always start by creating your Snowflake account online [OK]

Common Mistakes:

• Trying to create tables before having an account
• Assuming local software installation is needed
• Confusing account creation with cloud VM setup

2. Which SQL command is used inside Snowflake to create a new warehouse?

easy

A. NEW WAREHOUSE my_warehouse;

B. MAKE WAREHOUSE my_warehouse;

C. CREATE WAREHOUSE my_warehouse;

D. BUILD WAREHOUSE my_warehouse;

Solution

1. Step 1: Recall Snowflake SQL syntax for warehouse creation

   The correct command to create a warehouse is CREATE WAREHOUSE followed by the warehouse name.

2. Step 2: Identify correct keyword usage

   Only CREATE is valid; MAKE, NEW, and BUILD are not valid SQL commands in Snowflake.

3. Final Answer:

   CREATE WAREHOUSE my_warehouse; -> Option C

4. Quick Check:

   Use CREATE for new objects [OK]

Hint: Use CREATE keyword to make new Snowflake objects [OK]

Common Mistakes:

• Using non-SQL keywords like MAKE or BUILD
• Omitting the CREATE keyword
• Incorrect command order

3. Given the SQL commands run inside Snowflake:

CREATE WAREHOUSE wh1;
CREATE DATABASE db1;
USE DATABASE db1;
CREATE SCHEMA sc1;

What is the current active schema after these commands?

medium

A. sc1

B. wh1

C. db1.sc1

D. db1.public

Solution

1. Step 1: Analyze commands executed

   The commands create a warehouse, a database, switch to that database, and create a schema inside it. However, no command sets the active schema explicitly.

2. Step 2: Understand default schema behavior

   When you use a database but do not set a schema, Snowflake defaults to the public schema inside that database.

3. Final Answer:

   db1.public -> Option D

4. Quick Check:

   Default schema = public if not set [OK]

Hint: Without USE SCHEMA, default is database.public [OK]

Common Mistakes:

• Assuming created schema is active automatically
• Confusing warehouse with schema
• Ignoring default schema behavior

4. You run this command in Snowflake:

CREATE WAREHOUSE mywh WITH WAREHOUSE_SIZE = 'LARGE';

But get an error. What is the likely cause?

medium

A. Warehouse size must be lowercase like 'large'

B. The WITH keyword is not valid for specifying warehouse parameters

C. Missing semicolon at the end

D. Warehouse name 'mywh' is reserved

Solution

1. Step 1: Check parameter syntax for warehouse creation

   The correct syntax is CREATE WAREHOUSE mywh WAREHOUSE_SIZE = 'LARGE'; -- parameters like WAREHOUSE_SIZE follow directly after the warehouse name, without WITH.

2. Step 2: Identify the syntax error

   Using WITH causes a syntax error because it is not part of the CREATE WAREHOUSE syntax.

3. Final Answer:

   The WITH keyword is not valid for specifying warehouse parameters -> Option B

4. Quick Check:

   No WITH for warehouse params [OK]

Hint: Warehouse parameters listed directly after name, no WITH [OK]

Common Mistakes:

• Using the WITH keyword incorrectly
• Assuming case sensitivity causes error
• Forgetting semicolon (usually not fatal in Snowflake)

5. You want to create a Snowflake workspace with a warehouse named wh_test, a database db_test, and a schema sc_test. Which sequence of commands correctly sets up the workspace and makes sc_test the active schema?

hard

A. CREATE WAREHOUSE wh_test; CREATE DATABASE db_test; USE DATABASE db_test; CREATE SCHEMA sc_test; USE SCHEMA sc_test;

B. CREATE DATABASE db_test; CREATE WAREHOUSE wh_test; CREATE SCHEMA sc_test; USE SCHEMA sc_test;

C. CREATE WAREHOUSE wh_test; CREATE SCHEMA sc_test; CREATE DATABASE db_test; USE SCHEMA sc_test;

D. CREATE WAREHOUSE wh_test; CREATE DATABASE db_test; CREATE SCHEMA sc_test; USE DATABASE db_test;

Solution

1. Step 1: Create warehouse and database in correct order

   First create the warehouse, then the database. Then switch to the database to create schema inside it.

2. Step 2: Create schema and set it active

   After creating the schema, use USE SCHEMA sc_test; to make it the active schema for commands.

3. Final Answer:

   CREATE WAREHOUSE wh_test; CREATE DATABASE db_test; USE DATABASE db_test; CREATE SCHEMA sc_test; USE SCHEMA sc_test; -> Option A

4. Quick Check:

   Correct order and active schema set [OK]

Hint: Always USE DATABASE before creating schema, then USE SCHEMA [OK]

Common Mistakes:

• Creating schema before switching to database
• Not setting active schema after creation
• Wrong command order causing errors
