+# SHUTDOWN
+
+The `SHUTDOWN` statement is used to perform a shutdown operation in TiDB. Execution of the `SHUTDOWN` statement requires the user to have `SHUTDOWN privilege`.
+
+## Synopsis
+
+**Statement:**
+
+![Statement](/media/sqlgram/ShutdownStmt.png)
+
+## Examples
+
+{{< copyable "sql" >}}
+
+```sql
+SHUTDOWN;
+```
+
+```
+Query OK, 0 rows affected (0.00 sec)
+```
+
+## MySQL compatibility
+
+> **Note:**
+>
+> Because TiDB is a distributed database, the shutdown operation in TiDB stops the client-connected TiDB instance, not the entire TiDB cluster.
+
+The `SHUTDOWN` statement is partly compatible with MySQL. If you encounter any compatibility issues, you can report the issues [on GitHub](/report-issue.md).
