• validatePrimaryKeyNullability

  public void validatePrimaryKeyNullability()
                                     throws StandardException

  Validate nullability of primary keys. This logic was moved out of the main validate method so that it can be called after binding generation clauses. We need to perform the nullability checks later on because the datatype may be omitted on the generation clause--we can't set/vet the nullability of the datatype until we determine what the datatype is.

  StandardException

  initiallyDeferred - True means the deferrable constraint has deferred mode

  indexName - The type of index (BTREE, for example)

  cdn -

  columnNames - Names of the columns in the index, in order.

  isConstraint - TRUE if index is backing up a constraint, else FALSE.

• checkIndexPageSizeProperty

  private java.util.Properties checkIndexPageSizeProperty​(ConstraintDefinitionNode cdn)
                                                   throws StandardException

  Checks if the index should use a larger page size. If the columns in the index are large, and if the user hasn't already specified a page size to use, then we may need to default to the large page size in order to get an index with sufficiently large pages. For example, this DDL should use a larger page size for the index that backs the PRIMARY KEY constraint: create table t (x varchar(1000) primary key)

  Parameters:

  cdn - Constraint node

  Returns:

  properties to use for creating the index

  Throws:

  StandardException
