Comparison Features

Full schema and data comparison with automatic synchronization script generation.

Schema Comparison

Compare tables, columns, indexes, constraints, procedures, functions, views, and triggers. Filter by Equal, Modified, Source Only, or Target Only.

Data Comparison

Discover matching tables, choose All / Selected / Single scope, and find inserts, updates, and deletes with PK-aware row matching.

Sync Script Generation

Generate T-SQL to align target with source. Copy to clipboard or save a .sql file for review in SSMS before you execute.

Side-by-Side Definitions

Inspect source and target definitions for any selected schema object with color-coded status badges.

Filter & Scope

Narrow results by name and status. Swap Source ↔ Target instantly when you need to reverse compare direction.

Dual Connection UI

Connect source and target independently with Windows, SQL, or Azure Entra auth — including cross-server and Azure comparisons.
