# Semantic Conventions for MSSQL
|
|
|
|
**Status**: [Experimental][DocumentStatus]
|
|
|
|
The Semantic Conventions for the [Microsoft SQL Server](https://www.microsoft.com/sql-server) extend and override the [Database Semantic Conventions](database-spans.md)
|
|
that describe common database operations attributes in addition to the Semantic Conventions
|
|
described on this page.
|
|
|
|
`db.system` MUST be set to `"mssql"`.
|
|
|
|
## Connection-level attributes
|
|
|
|
<!-- semconv db.mssql(tag=connection-level-tech-specific) -->
|
|
| Attribute | Type | Description | Examples | Requirement Level |
|
|
|---|---|---|---|---|
|
|
| [`db.jdbc.driver_classname`](database-spans.md) | string | The fully-qualified class name of the [Java Database Connectivity (JDBC)](https://docs.oracle.com/javase/8/docs/technotes/guides/jdbc/) driver used to connect. | `org.postgresql.Driver`; `com.microsoft.sqlserver.jdbc.SQLServerDriver` | Recommended |
|
|
| `db.mssql.instance_name` | string | The Microsoft SQL Server [instance name](https://docs.microsoft.com/en-us/sql/connect/jdbc/building-the-connection-url?view=sql-server-ver15) connecting to. This name is used to determine the port of a named instance. [1] | `MSSQLSERVER` | Recommended |
|
|
|
|
**[1]:** If setting a `db.mssql.instance_name`, `server.port` is no longer required (but still recommended if non-standard).
