+# DatabaseClose
+
+Closes a database.
+
+```
+void  DatabaseClose(
+   int  database      // database handle received in DatabaseOpen
+   );
+
+```
+
+Parameters
+
+database
+
+[in]  Database handle received in [DatabaseOpen()](/en/docs/database/databaseopen).
+
+Return Value
+
+None.
+
+Note
+
+After calling DatabaseClose, all [handles of requests ](/en/docs/database/databaseprepare) to the database are automatically removed and become invalid.
+
+If the handle is invalid, the function sets the ERR_DATABASE_INVALID_HANDLE error. You can check the error using GetLastError().
