SQL

The Nasdaq Data Link SQL interface works with data in tables formats. This page explains how to find out the format or appropriate API for each data product.

DataLink SQL Interface is an interactive query service that makes it easy to analyze data in DataLink using standard SQL. With DataLink SQL, there’s no need for custom scripts to download and manually assemble your data for analysis. This makes it easy for anyone with SQL skills to quickly analyze large-scale datasets.

DataLink SQL is out-of-the-box integrated with the DataLink catalog, allowing you to discover and interact with all your DataTables using your DataLink API Key.

Powered by Trino runs standard SQL
DataLink SQL uses Trino (formerly Presto SQL) with ANSI SQL support. It is ideal for interactive querying and can also handle complex analysis, including large joins, window functions, and arrays. You can utilize any Trino API compatible 1st or 3rd party clients to connect to DataLink SQL.

Unified Catalog
DataLink SQL exposes a standard interface to query underlying DataLink data stores, and gives you a consistent experience for regular and large partitioned DataTables. Your existing API Keys can be used to query the same DataTables via SQL as you already do with via DataTables API or existing DataLink clients.
