Why teams connect Box and SQL Server

Keep SQL Server and Box in step: a row in SQL Server for every file in Box, with names, paths, metadata, and status staying consistent in real time, in both directions.

A database holds structured records; a storage system holds the files those records depend on, such as contracts, images, exports, uploads, and documents. The two describe the same things from opposite sides: a row in SQL Server says a file exists and carries its name, location, and status, while Box holds the bytes. Linked only by a hand-kept path or a one-off script, the two drift the moment a file is renamed, moved, or deleted and the record still points at where it used to be.

Stacksync syncs Stored Procedures, Databases, Schemas, Tables in SQL Server with Groups, Tasks, Events, Files in Box bi-directionally and in real time. File attributes, including name, path or object key, size, type, modified time, owner, and tags or custom properties, map field by field to columns on the matching row, and a change on either side shows up on the other within seconds. New files appear as rows, metadata edits travel in the direction you choose, and deletes stay consistent, with conflict rules you set in place of nightly reconciliation scripts.

Common use cases

  • 01 Mirror on-premises ERP data held in SQL Server into cloud CRM and support systems
  • 02 Feed a cloud warehouse from SQL Server continuously using native CDC instead of SSIS batch jobs
  • 03 Push generated documents from an ERP or contract system into Box Folders with the right Collaborations applied for the deal team.
  • 04 Stream enterprise Events (admin events) into a warehouse for audit, DLP, and access-review reporting.

Common sync patterns

A queryable index of the file store

Every file or object in Box shows up as a row in SQL Server, with its name, folder or key, size, type, and modified date as columns, so the contents of the store can be listed, filtered, and joined like any other table.

File metadata kept in step

Tags, custom properties, owner, or status columns edited on a row in SQL Server write back to the matching file's metadata in Box, and metadata changed in Box updates the row, so the two never disagree about a file.

Records that point at documents

Where a record in SQL Server references a file in Box, such as a contract, an image, an export, or an upload, the reference, path, and status stay consistent as files are renamed, moved, or replaced, so stored links keep resolving.

What you can sync between Box 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.

Box objects SQL Server objects How this pairing syncs
Collaborations Access grants linking a user or group to a file or folder with a role such as viewer, editor, or co-owner; written to manage sharing programmatically. Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Collaborations is specific to Box and Primary and Unique Keys to SQL Server — each maps to any object or custom field on the other side.
Users Managed and app users in the enterprise; provisioned, updated, and deprovisioned to keep Box access aligned with an HR or identity source. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. Users is specific to Box and CDC Change Tables to SQL Server — each maps to any object or custom field on the other side.
Groups Named user collections used for bulk collaboration; membership synced from a directory or IdP. Stored Procedures T-SQL logic that can validate or post-process synced rows. Groups is specific to Box and Stored Procedures to SQL Server — each maps to any object or custom field on the other side.
Tasks Review or approval assignments on a file with due dates and states; read for workflow reporting or written to start approvals. Databases Instance-level databases that scope a sync's reads and writes. Tasks is specific to Box and Databases to SQL Server — each maps to any object or custom field on the other side.
Events Enterprise admin event stream, an audit log of uploads, deletes, logins, and shares across the account; read-only, consumed for reporting or change feeds. Schemas Namespaces (dbo and custom) used to organize synced tables. Events is specific to Box and Schemas to SQL Server — each maps to any object or custom field on the other side.
Files Core content object with versions, name, size, and metadata; synced two-way so files and their attributes move between Box and a database or another store. Tables The primary sync target; rows map to records in connected systems. Files is specific to Box and Tables to SQL Server — each maps to any object or custom field on the other side.

How changes propagate between Box and SQL Server

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Box SQL Server Sub-second propagation

DetectionBox notifies Stacksync of record changes through webhook events. V2 webhooks fire on triggers such as FILE.UPLOADED, FILE.TRASHED, and METADATA_INSTANCE.UPDATED.

DeliveryEach detected change is applied to SQL Server as a row-level write, with types converted between the two schemas.

SQL Server Box Sub-second propagation

DetectionChanges in SQL Server are captured at the source via change data capture — no polling loop against its API. SQL Server Native Change Data Capture (CDC).

DeliveryEach detected change is written to Box through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Box: Per user: 1,000 API calls per minute and 240 file uploads per minute; exceeding limits returns HTTP 429 with a Retry-After header. Box Business plans also carry a licensed monthly API-call allotment per enterprise.
  • SQL Server: No API rate limits; throughput depends on instance resources, licensing tier, and connection limits.
