Typical Storage screen for a Greenplum table
Location
Fields | Description |
|---|---|
Target Location | The target location that defines the path of the table. Select (local) for a local table or select the target schema if you are locating tables in different schemas. Note The Force Target Usage setting in the Tools > Options > Storage > Target Usage removes the local target option from the drop-down list. Refer to Target Usage for details.
Note When upgrading from a RED version previous to 6.8.2.0 and moving existing objects to a target location, all procedures that reference those objects need to be rebuilt. Any FROM clauses will also need to be manually regenerated in order for the table references to be updated to the new [TABLEOWNER] form. Warning If the database type does not support moving tables, such as Oracle, Greenplum, Netezza, Teradata and PDW, all affected tables need to be manually recreated after any storage changes. Please note that changing the Storage for Dimension and Fact tables need to be handled very carefully, as artificial key relationships between Dimension and Fact could become out of sync. Recreating Fact tables and large Dimension tables might take a considerable amount of time. |
Database Type | The database type for a connection that is used for target Datawarehouse tables. |
Database | The database where the table is located. Leave blank to use the default for the connection or local environment. |
Schema | The schema where the table is located. |
Owner | Owner to which the object is altered. |
Create DDL Template | Optional. Specify the template to use when creating a new DDL procedure script. This option is only visible if a DDL template is available for this database type. Default value is None. |

Enable Fill Factor
Tip
Setting this will enable setting of the Fill Factor.
