Schema Comparison. Analyzes differences in the database structure, including tables, views, stored procedures, and functions. It identifies modified columns, new constraints, altered indexes, and triggers. Structural review is a methodological step for database migration or consolidation.
Data Comparison. Examines the content of tables and views to locate distinct, missing, or modified records. The tool performs row-by-row comparisons, highlighting discrepancies in values. This process verifies the integrity and uniformity of information across environments.
Data Merge. Transfers selected records from one database to another. The operation generates and executes SQL scripts for insertion, update, or deletion. The merge maintains data consistency across different servers or development environments.
Batch Data Merge. Synchronizes data across multiple tables or views in a single, coordinated operation. It configures and executes a predefined set of merge actions. This method streamlines replication tasks or updates for entire databases.
Diff Profiles. Saves specific configurations for recurring analyses. Profiles store connection parameters, object selections, and comparison rules. This feature automates periodic reviews between the same datasets.
Id-Remap Merge. Handles the synchronization of tables with identity or sequence primary keys. It automatically reassigns key values to avoid conflicts during the merge. This technique is necessary when source and target systems generate their own unique values.
Query Result Diff. Analyzes the differences between the result sets of two arbitrary SQL queries. This function compares derived or transformed data, not limited to base tables. It facilitates the validation of complex business logic or aggregated data across different databases.
Export to XLSX and JSON Format. Saves comparison results or merge scripts to Microsoft Excel XLSX files or JSON format. XLSX reports allow for external review and analysis. Export to JSON enables automated processing by other tools or systems.
Command Line Interface (CLI). Provides execution of functions from the terminal, available for Windows, Linux, and Subsystem for Linux (WSL). The CLI allows integration of comparisons and merges into automation scripts or deployment pipelines. It supports non-interactive operations for server environments.
GUI Script Editor. Offers an integrated environment to view, modify, and execute the SQL scripts generated by comparison and merge operations. It displays the commands to be applied to the database, allowing for manual adjustments before execution. This control prevents unwanted changes during synchronization.
Data Slices. Defines and compares customized subsets of data within a batch comparison operation. It filters specific information by criteria such as date ranges, column values, or custom conditions. This function focuses the analysis on data segments relevant to a particular task.
Application Customization. Adjusts the software's behavior and appearance through settings. It modifies highlight colors, keyboard shortcuts, and default parameters for database connections. Adaptation optimizes the workflow according to the operator's requirements.
Change Navigation. Moves the interface focus between identified differences in a sequential order. It jumps to the next or previous schema or data discrepancy with dedicated commands. This systematic navigation speeds up the review of long lists of modifications.
Advanced Search. Locates specific text within the metadata of database objects or within the displayed data. It applies complex filters and conditions to the search. It finds references to column names, particular values, or code snippets in stored procedures.

The development of MssqlMerge began in 2015 by KS DB Merge Tools. The development team specializes in creating utilities for database administration and comparison. The software is primarily written in the C# programming language, using the .NET framework.
