Unique Constraint property sheet: General tab

The General tab of the Unique Constraint property sheet has the following components:

Name    Shows the name of the unique constraint. You can change the name of the unique constraint in the adjacent field.

Type    Shows the type of object.

Table    Shows the table to which the unique constraint belongs.

Clustered    Shows whether the table containing the unique constraint has a clustered index. Clustered indexes are supported for Adaptive Server Anywhere databases that are version 8.0.2 and higher.

Clustered indexes in Adaptive Server Anywhere store the table rows in approximately the same order as they appear in the corresponding index. Using a clustered index can lead to performance benefits by reducing the number of times each page needs to be read into memory. Only one index on a table can be a clustered index.

For more information about clustered indexes, see .

Index type    Shows the type of index the table has.
