      public UniqueConstraint(String name, String tableCatalog, String tableSchema, String tableName, Column... columns)

  • Method Details

    • getContainingObjects

      public DatabaseObject[] getContainingObjects()

    • getName

    • setName

      public UniqueConstraint setName(String constraintName)
      Description copied from interface: DatabaseObject
      Sets the name for the database object.
      Parameters:
      constraintName - the new name for the database object
      Returns:
      a reference to the same object (implementing classes are expected to return a reference to the same object).

    • getSchema

      public Schema getSchema()

    • getTable

      @Deprecated public Table getTable()
      Deprecated.
      Use getRelation()

    • setTable

      @Deprecated public UniqueConstraint setTable(Table table)
      Deprecated.
      Use setRelation(Relation)

    • getRelation

      public Relation getRelation()

    • setRelation

      public UniqueConstraint setRelation(Relation relation)

    • getColumns

      public List<Column> getColumns()

    • setColumns

      public UniqueConstraint setColumns(List<Column> columns)

    • addColumn

      public UniqueConstraint addColumn(int position, Column column)

    • isDeferrable

      public boolean isDeferrable()

    • setDeferrable

      public UniqueConstraint setDeferrable(boolean deferrable)

    • shouldValidate

      public boolean shouldValidate()
      In Oracle PL/SQL, the VALIDATE keyword defines whether a newly added unique constraint on a column in a table should cause existing rows to be checked to see if they satisfy the uniqueness constraint or not.
      Returns:
      true if ENABLE VALIDATE (this is the default), or false if ENABLE NOVALIDATE.

    • setShouldValidate

      public UniqueConstraint setShouldValidate(boolean shouldValidate)
      Parameters:
      shouldValidate - - if shouldValidate is set to FALSE then the constraint will be created with the 'ENABLE NOVALIDATE' mode. This means the constraint would be created, but that no check will be done to ensure old data has valid constraints - only new data would be checked to see if it complies with the constraint logic. The default state for unique constraints is to have 'ENABLE VALIDATE' set.
