What Stacksync syncs in SQL Server.

These objects sync between SQL Server and any connected system, with field-level mapping and conflict resolution. Custom fields are picked up from the live schema where SQL Server exposes them.

Databases
Instance-level databases that scope a sync's reads and writes.
Schemas
Namespaces (dbo and custom) used to organize synced tables.
Tables
The primary sync target; rows map to records in connected systems.
Views
Read-side projections used as outbound sync sources.
Columns
Field-level mapping targets with T-SQL types.
Primary and Unique Keys
Match keys for idempotent upserts and conflict handling.
CDC Change Tables
System-populated tables holding captured inserts, updates, and deletes for consumers.
Stored Procedures
T-SQL logic that can validate or post-process synced rows.
API surface

How Stacksync connects to SQL Server.

The connector runs on SQL Server's native API. Stacksync manages authentication, rate limits, retries, and schema changes so your team does not maintain integration code.

Connection
SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers
Authentication
Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page
Change detection
SQL Server Native Change Data Capture (CDC); a DBA runs a one-time setup script with sysadmin privileges to enable CDC and create Stacksync wrapper procedures
Rate limits
No API rate limits; throughput depends on instance resources, licensing tier, and connection limits

What ships with SQL Server

Connect SQL Server for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every connection.

Real-time

Two-way sync

Changes in SQL Server instantly reflect across connected systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever SQL Server data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single SQL Server record.

Observability

Monitoring

Track your SQL Server sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions.

Use cases

What teams run on the SQL Server connector.

Microsoft positions SQL Server as its enterprise relational database - SQL Server 2022 is described as "the most Azure-enabled release yet" - aimed at organizations running hybrid estates with 24/7 availability requirements. IT and DBA teams operate it behind ERP systems, .NET line-of-business applications, and operational workloads, so Databases and Schemas carry years of transactional records that other systems need to read and update under tight access control.

  • IT / DBAs
  • .NET and backend engineering
  • Data engineering
  • ERP admins

  1. Bi-directional sync between SQL Server rows and CRM objects so .NET line-of-business apps and sales tools share one dataset

  2. Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query

  3. Mirror on-premises ERP data held in SQL Server into cloud CRM and support systems

  4. Feed a cloud warehouse from SQL Server continuously using native CDC instead of SSIS batch jobs

  5. Consolidate branch or plant databases into a single operational SQL Server hub

  6. Two-way sync of customer, order, or asset Tables with a CRM so sales and support work from ERP-grade records while updates flow back to the database of record.

How it works

Set up SQL Server in minutes, without APIs.

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate SQL Server with its native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

    Choose tables

    Pick the SQL Server objects to sync — Stacksync auto-detects the schema, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.

FAQ

SQL Server connector FAQ

What can I sync with the SQL Server connector?

SQL Server's core objects — Databases, Schemas, Tables, Views and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to SQL Server?

Via SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers, authenticated with Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page. Changes are detected as follows — sQL Server Native Change Data Capture (CDC); a DBA runs a one-time setup script with sysadmin privileges to enable CDC and create Stacksync wrapper procedures. Stacksync manages rate limits, retries, and schema changes automatically.

Is the SQL Server connector two-way?

Yes. Changes made in SQL Server propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does a SQL Server integration take to set up?

Most SQL Server integrations go live in minutes: authenticate SQL Server and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is SQL Server data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. SQL Server data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
