SQL Delta
SQL Delta is a Windows tool for comparing database schemas and data before changes reach production. SQL Delta 7 compares source and target databases that use the same server type; SQL DXP is intended for comparisons across different server types. Schema Compare shows structural differences in live databases or snapshots and lets users select what to include in a deployment script. Data Compare identifies row-level differences between environments. Users can review and edit synchronization scripts before executing them against a target, and projects can add custom script to deployment scripts. SQL Delta can save HTML reports and XML snapshots for release reviews or recovery work. Project completion events and command-line execution support automated runs. Editions are listed for SQL Server, MySQL, Oracle, and PostgreSQL. A separate Read Only Edition allows comparison and script generation but prevents direct script execution. The latest full product download has a 14-day trial. The MySQL single-license plan is $185 as a one-time purchase and includes a two-year software update subscription; purchase terms also describe a perpetual license.
