Why teams connect eClinicalWorks and SQL Server

Mirror eClinicalWorks's data into SQL Server so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like eClinicalWorks through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in SQL Server.

Stacksync mirrors Observations, Medications, Allergies, Immunizations from eClinicalWorks into Columns, Primary and Unique Keys, CDC Change Tables, Stored Procedures in SQL Server and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into eClinicalWorks, so the tool and the database never disagree.

Common use cases

  • Feed appointment events to reminder and messaging platforms to reduce no-shows.
  • Keep provider directories consistent between eClinicalWorks and scheduling or marketing systems.
  • Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query
  • Mirror on-premises ERP data held in SQL Server into cloud CRM and support systems

React to changes as they happen

Updates in eClinicalWorks arrive as row changes in SQL Server, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read eClinicalWorks with a query

Records from eClinicalWorks are ordinary rows in SQL Server; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between eClinicalWorks and SQL Server

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

eClinicalWorks objects SQL Server objects
Immunizations Vaccination history exposed for registries and patient apps. Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
Documents Clinical notes and attachments referenced from the chart. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers.
Diagnostic reports Structured result reports grouping observations for a study or panel. Stored Procedures T-SQL logic that can validate or post-process synced rows.
Patients Demographic records exposed via FHIR Patient resources and HL7 ADT feeds; the anchor for all clinical syncs. Databases Instance-level databases that scope a sync's reads and writes.
Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach. Schemas Namespaces (dbo and custom) used to organize synced tables.
Encounters Visit records tying diagnoses, providers, and billing context together. Tables The primary sync target; rows map to records in connected systems.

How the eClinicalWorks and SQL Server connectors work

eClinicalWorks

Integration surface
FHIR R4 REST API plus HL7 v2 interfaces (ADT, SIU, ORU) through an interface engine
Authentication
OAuth 2.0 / SMART on FHIR for the FHIR API; site-configured credentials for HL7 interface connections
Change detection
HL7 interface feeds push event messages as they occur; the FHIR API is polled
Capabilities

Rate limits
Subject to the platform's API rate limits and interface throughput agreements

SQL Server

Integration surface
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
Capabilities
