As Listing 12-12 shows, this nested table join syntax is very similar to the syntax you use for regular joins (discussed in 8). The TABLE function unnests its column-valued argument (c.errata) into a table. Note that you can only refer to c.ERRATA because you specify the C table first in the FROM clause. The FROM clause order is important in this case. If you swap the two table expressions, you get the following Oracle error message: code c.description e.ch, e.pg, e.txt table(c.errata) e join c using (code); from table(c.errata) e * ERROR at line 4: ORA-00904: "C"."ERRATA": invalid identifier Listing 12-12 shows only a single row, because we inserted only a single erratum into the nested table. The last section of this chapter revisits nested tables, showing how you can use multiset operators on nested tables. These multiset operators could be a reason to consider using nested tables instead of regular (relational) tables with primary key and foreign key constraints. The multiset operators allow you to write elegant SQL statements that would need quite complicated syntax without them. select , , from

The third example mentioned in Section 12.1 was the compound ADDRESS type, used to store addresses with meaningful subcomponents into a single column. Listing 12-13 shows how you can create such a type. Listing 12-13.

; Note that we now have four user-defined types, as shown by the query against the USER_TYPES data dictionary view. Then we create a copy O of the OFFERINGS table (again, to keep the original table unimpaired) and add an ADDRESS column to the O table. As a last step, Listing 12-13 updates the O table with some address values. The last command uses the ADDRESS_T function to generate address values, leaving the first three address fields empty and selecting the city name from the original OFFERINGS table with a subquery.
Showing More Information with DESCRIBE
If you use user-defined datatypes, you can change the behavior of the SQL*Plus DESCRIBE command to show more information, by setting its DEPTH attribute to a value higher than 1 or to ALL. See Listing 12-14 for an example. Listing 12-14. Setting the DEPTH Attribute of the DESCRIBE Command describe o Name ----------------COURSE BEGINDATE TRAINER ADDRESS Null -------NOT NULL NOT NULL Type -----------VARCHAR2(4) DATE NUMBER(4) ADDRESS_T
set describe depth 2 describe o Name Null ----------------- -------COURSE NOT NULL BEGINDATE NOT NULL TRAINER ADDRESS STREET NR PCODE CITY
Type ---------------VARCHAR2(4) DATE NUMBER(4) ADDRESS_T VARCHAR2(20) VARCHAR2(5) VARCHAR2(6) VARCHAR2(20)
The DESCRIBE command now also shows the subcomponents of your user-defined types. If your object-relational tables have additional method functions, they are shown as well.

12.5 Multiset Operators
This section discusses the ANSI/ISO standard multiset operators of the SQL language. We will first look at a complete list of all SQL multiset operators with a brief description. You can use these operators only on nested tables. Therefore, to allow for some multiset operator examples in this section, we will enter some more nested table entries in the ERRATA nested table. You will also see how you can convert arrays into nested tables on the fly, using the CAST and COLLECT functions.
