# Semantic Conventions for SQL Databases
**Status**: [Experimental][DocumentStatus]
The SQL databases Semantic Conventions 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.
## Attributes
<!-- semconv db.sql(full,tag=tech-specific) -->
| Attribute | Type | Description | Examples | [Requirement Level](https://opentelemetry.io/docs/specs/semconv/general/attribute-requirement-level/) | Stability |
|---|---|---|---|---|---|
| [`db.collection.name`](../attributes-registry/db.md) | string | The name of the SQL table that the operation is acting upon. [1] | `public.users`; `customers` | `Conditionally Required` [2] | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
| [`db.operation.name`](../attributes-registry/db.md) | string | The name of the operation or command being executed. [3] | `SELECT`; `INSERT`; `UPDATE`; `DELETE`; `CREATE`; `mystoredproc` | `Conditionally Required` [4] | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
**[1]:** If the collection name is parsed from the query, it SHOULD match the value provided in the query and may be qualified with the schema and database name.
**[2]:** If readily available. Otherwise, if the instrumentation library parses `db.query.text` to capture `db.collection.name`, then it SHOULD be the first collection name found in the query.
**[3]:** This SHOULD be the SQL command such as `SELECT`, `INSERT`, `UPDATE`, `CREATE`, `DROP`.
In the case of `EXEC`, this SHOULD be the stored procedure name that is being executed.
**[4]:** If readily available. Otherwise, if the instrumentation library parses `db.query.text` to capture `db.operation.name`, then it SHOULD be the first operation name found in the query.

## Example
This is an example of attributes for a MySQL database span:
| Key | Value |
|:-----------------------| :----------------------------------------------------------- |
| Span name | `"SELECT ShopDb.orders"` |
| `db.system` | `"mysql"` |
| `server.address` | `"shopdb.example.com"` |
| `server.port` | `3306` |
| `network.peer.address` | `"192.0.2.12"` |
| `network.peer.port` | `3306` |
| `network.transport` | `"tcp"` |
| `db.name` | `"ShopDb"` |
| `db.query.text` | `"SELECT * FROM orders WHERE order_id = 'o4711'"` |
| `db.operation.name` | `"SELECT"` |
| `db.collection.name` | `"orders"` |
