Class UniqueConstraintAddition

java.lang.Object

com.atlassian.confluence.internal.upgrade.constraint.UniqueConstraintAddition

public class UniqueConstraintAddition
extends Object

Add a unique constraint if not exist. Duplicates will be cleaned if needed before the unique constraint can be added. Note: all table and column names must not be quoted. The reason is RDBMS vendors treat identifier case sensitivity differently so generally identifiers can only be quoted they have been created with quotes originally.

Since:

7.1.0
