Learn Partiql - 10 Code Examples & CST Typing Practice Test

PartiQL is a SQL-compatible, open-source query language designed for querying structured, semi-structured, and nested data uniformly. It allows SQL-style queries over relational databases, NoSQL systems like DynamoDB, document stores, and nested data formats such as JSON-all without data transformation.

Code Sample Descriptions

Basic PartiQL Queries

SELECT name, age FROM users
WHERE age > 25;

UPDATE users
SET age = 31
WHERE id = 'user_123';

Querying and modifying data in DynamoDB using PartiQL.

Let’s Try →

Insert Item PartiQL

INSERT INTO users VALUE {
    'id': 'user_456',
    'name': 'Charlie',
    'age': 28
};

Inserting a new item into DynamoDB with PartiQL.

Let’s Try →

Delete Item PartiQL

DELETE FROM users
WHERE id = 'user_123';

Deleting an item by primary key in DynamoDB.

Let’s Try →

Conditional Update PartiQL

UPDATE users
SET age = 40
WHERE id = 'user_456' AND age < 35;

Updating an item only if a condition matches.

Let’s Try →

Select With Projection PartiQL

SELECT name, email
FROM users
WHERE active = true;

Querying only specific attributes from a table.

Let’s Try →

Batch Insert PartiQL

INSERT INTO users VALUE {
    'id': 'user_789', 'name': 'Dana', 'age': 22
},
{
    'id': 'user_790', 'name': 'Eli', 'age': 35
};

Inserting multiple items into a DynamoDB table.

Let’s Try →

Select With IN Clause PartiQL

SELECT * FROM users
WHERE id IN ['user_123', 'user_456', 'user_789'];

Selecting items using the IN clause.

Let’s Try →

Select With BETWEEN PartiQL

SELECT name, age
FROM users
WHERE age BETWEEN 20 AND 30;

Querying numeric ranges with BETWEEN.

Let’s Try →

Nested Attribute PartiQL

SELECT address.city, address.zip
FROM users
WHERE id = 'user_789';

Accessing nested attributes inside a DynamoDB item.

Let’s Try →

Order By PartiQL

SELECT name, age
FROM users
ORDER BY age DESC;

Sorting query results using ORDER BY.

Frequently Asked Questions about Partiql

What is Partiql?

What are the primary use cases for Partiql?

Querying DynamoDB using SQL-like syntax. Querying nested JSON objects. Federated querying across relational and NoSQL stores. Serverless analytics without ETL. Schema-flexible applications. Data lakes with mixed formats

What are the strengths of Partiql?

Uniform SQL querying across data models. Excellent for semi-structured cloud data. Reduces ETL complexity. Developer-friendly for SQL users. Works seamlessly with DynamoDB

What are the limitations of Partiql?

Not a full SQL replacement for all engines. Feature completeness varies by implementation. Complex nested queries can get verbose. Performance depends on backend (e.g., DynamoDB capacity)

How can I practice Partiql typing speed?

CodeSpeedTest offers 10+ real Partiql code examples for typing practice. You can measure your WPM, track accuracy, and improve your coding speed with guided exercises.
