DROP SEQUENCE

Removes the specified named sequence number generator.

Syntax

DROP SEQUENCE [ IF EXISTS ] [[database.]schema.]sequence[,...]

`IF EXISTS`	Specifies not to report an error if the sequences to drop do not exist. Use this clause in SQL scripts to avoid errors on dropping non-existent objects before attempting to create them.
`[database.]schema`	Database and schema. The default schema is `public`. If you specify a database, it must be the current database.
sequence	Name of the sequence to drop.

Non-superusers: sequence or schema owner

For sequences specified in a table's default expression, the default expression fails the next time you try to load data. Vertica does not check for these instances.
DROP SEQUENCE does not support the CASCADE keyword. Sequences used in a default expression of a column cannot be dropped until all references to the sequence are removed from the default expression.

The following command drops the sequence named sequential.

=> DROP SEQUENCE sequential;
