Specifies the name of an item in a record. Do not give the same
    name for two record items at the same level in the same record
    declaration.

    When SQL statements within a procedure refer to an item name
    within a subrecord in the same procedure as a parameter
    declaration, they must fully qualify the item name with the
    record name and all intervening subrecord names. Separate record
    names from item names with periods.
