SQL Server
Category: Direct connection
Microsoft SQL Server. Direct connection. In Yres this source has the source type MSSQL; in the data warehouse it is processed as source type MSSQL_ADF.
Expected input
When you create the source (the Add source wizard), besides the general fields — source name, type, integration runtime, "credentials identical across all environments?", credential expiry date, tags — you fill in the following connection fields:
| Field | Description |
|---|---|
| Host | Server name or IP address of the SQL Server (for a named instance, optionally server\instance). |
| Port | The database's listening port (default 1433). |
| Database name | Name of the specific database (catalog). |
| Username | SQL login with read access to the database. |
| Password | Password for that user. |
- Authentication: Basic (username + password).
- Integration runtime: by default the cloud runtime
AutoResolveIntegrationRuntimewhen the server is publicly reachable. If the server is on-premises or behind a firewall, choose a self-hosted integration runtime (pwccIntegrationRuntimeLinked); this must be published first. - No secrets in the frontend: your password is never stored in the web app. Yres writes the details as a single Key Vault secret to the Azure Key Vault of your own environment, under the name
adf-{bronnaam}-connectionstring. The ADF linked service (type: SqlServer) references that secret.
Unlike, for example, MySQL, Oracle and Snowflake, SQL Server has no separate modern deploy builder. The source is published through the older SourceSystemManager route (AddLinkedService), with one combined secret adf-{sourcename}-connectionstring in the Key Vault instead of separate secrets per field.
Gathering the details
These values come from your database administrator (DBA) or from the existing JDBC/ODBC connection string.
- Host / Port — Host is the server name or IP address on which SQL Server runs (for a named instance, optionally
server\instance); Port is the database's listening port (default 1433). Found in the server configuration, or available from your DBA. - Database name — The name of the specific database (catalog) you want to connect to.
- Username / Password — Preferably use a dedicated SQL service account with read-only rights (least privilege) on the relevant database, rather than a personal or admin account.
Is the database behind a firewall or on-premises? Then a self-hosted Integration Runtime is needed to establish the connection — see Connecting a data source.
Load types and delta
All standard load types are available (FULL, DELTA, DELTAIMAGE, IMAGE, OVERWRITE, RELOAD, ADDITIONAL). For SQL Server, two delta columns are supported for incremental loading — this is the norm for SQL sources (only MySQL is an exception here and supports a single delta column).
