The name of the database you want to drop. |
Examples
> SHOW DATABASES;
+----------+
| Database |
+----------+
| db1 |
| system |
+----------+
> DROP DATABASE db1;
> DROP DATABASE db2;
pq: database "db2" does not exist
To avoid an error in case the database does not exist, you can include IF EXISTS:
> DROP DATABASE IF EXISTS db2;
> SHOW DATABASES;
+----------+
| Database |
+----------+
| system |
+----------+
Warning:
DROP DATABASE drops all tables within the database as well as objects dependent on the tables without listing the tables or the dependent objects. This can lead to inadvertent and difficult-to-recover losses. To avoid potential harm, we recommend dropping objects individually in most cases.See Also
