Migrations, Database Schema & Data Management Mid-Level Intermediate

Quick Interview Answer

EF Core tooling can generate SQL representing migration operations. A SQL script can be reviewed, archived, tested, and executed by a database administrator or deployment pipeline.

Detailed Explanation

EF Core tooling can generate SQL representing migration operations. A SQL script can be reviewed, archived, tested, and executed by a database administrator or deployment pipeline.

This is valuable for production environments where application identities do not have schema-change permissions or where database changes require formal review.

Always generate scripts using the correct provider and migration range for the target environment.

Code Example

dotnet ef migrations script -o migration.sql

# Package Manager Console
Script-Migration
