I was particularly interested in testing the new Half-precision float support in vector data type. To do this, I deployed SQL Server RHEL10 (the tag is 2025-RC1-rhel-10) container on WSL2 and I already have Docker Desktop installed on my local machine to manage containers. I launched the SQL Server 2025 RC1 container, connected to it using SQL Server Management Studio (SSMS), and successfully tested the vector data type enhancement. docker pull mcr.microsoft.com/mssql/rhel/server:2025-RC1-rhel-10 docker run -e "ACCEPT_EULA=Y" -e "MSSQL_SA_PASSWORD=passwordshouldbestrong" \ -e "MSSQL_AGENT_ENABLED=true" \ -p 14337:1433 --name sql2025RC1RHEL10 --hostname sql2025RC1RHEL10 \ -d mcr.microsoft.com/mssql/rhel/server:2025-RC1-rhel-10 SELECT @@VERSION GO CREATE DATABASE SQL2025onRHEL10 GO USE SQL2025onRHEL10 GO -- Step 0: Enable Preview Features ALTER DATABASE SCOPED CONFIGURATION SET PREVIEW_FEATURES = ON; GO -- Step 1: Create a Table with a VECTOR(5, float16) Column CREATE TABLE dbo.Articles ( id INT PRIMARY KEY, title NVARCHAR(100), content NVARCHAR(MAX), embedding VECTOR(5, float16) ); -- Step 2: Insert Sample Data INSERT INTO Articles (id, title, content, embedding) VALUES (1, 'Intro to AI', 'This article introduces AI concepts.', '[0.1, 0.2, 0.3, 0.4, 0.5]'), (2, 'Deep Learning', 'Deep learning is a subset of ML.', '[0.2, 0.1, 0.4, 0.3, 0.6]'), (3, 'Neural Networks', 'Neural networks are powerful models.', '[0.3, 0.3, 0.2, 0.5, 0.1]'), (4, 'Machine Learning Basics', 'ML basics for beginners.', '[0.4, 0.5, 0.1, 0.2, 0.3]'), (5, 'Advanced AI', 'Exploring advanced AI techniques.', '[0.5, 0.4, 0.6, 0.1, 0.2]'); -- Step 3: Perform a Vector Similarity Search Using VECTOR_DISTANCE function DECLARE @v VECTOR(5, float16) = '[0.3, 0.3, 0.3, 0.3, 0.3]'; SELECT TOP (3) id, title, VECTOR_DISTANCE('cosine', @v, embedding) AS distance FROM dbo.Articles ORDER BY distance; -- Step 4: Optionally Create a Vector Index CREATE VECTOR INDEX vec_idx ON Articles(embedding) WITH ( metric = 'cosine', type = 'diskANN' ); -- Step 5: Perform a Vector Similarity Search DECLARE @qv VECTOR(5, float16) = '[0.3, 0.3, 0.3, 0.3, 0.3]'; SELECT t.id, t.title, t.content, s.distance FROM VECTOR_SEARCH( table = Articles AS t, column = embedding, similar_to = @qv, metric = 'cosine', top_n = 3 ) AS s ORDER BY s.distance, t.title; Conclusion The addition of RHEL10 support in SQL Server 2025 Preview is a major milestone in delivering a modern, secure, and flexible data platform for Linux users.
