Moving tables to another schema
ALTER TABLE...SET SCHEMA
moves a table from one schema to another. Vertica automatically moves all projections that are anchored to the source table to the destination schema. It also moves all IDENTITY columns to the destination schema.
Moving a table across schemas requires that you have USAGE
privileges on the current schema and CREATE
privileges on destination schema. You can move only one table between schemas at a time. You cannot move temporary tables across schemas.
Name conflicts
If a table of the same name or any of the projections that you want to move already exist in the new schema, the statement rolls back and does not move either the table or any projections. To work around name conflicts:
-
Rename any conflicting table or projections that you want to move.
-
Run
ALTER TABLE...SET SCHEMA
again.
Note
Vertica lets you move system tables to system schemas. Moving system tables could be necessary to support designs created through the Database Designer.Example
The following example moves table T1
from schema S1
to schema S2
. All projections that are anchored on table T1
automatically move to schema S2
:
=> ALTER TABLE S1.T1 SET SCHEMA S2;
