A multiple-row subquery returns multiple rows in the output, so you need to use multiple-row comparison operators, such as IN, ANY, and ALL. Using a single-row operator with a multiple-row subquery returns this common Oracle error: ERROR: ORA-01427: single-row subquery returns more than one row

The SQL Performance Analyzer contains both a result summary and a result details section. The former shows quickly whether the database upgrade in our example will result in any performance deterioration or improvement. The advisor also provides recommendations to avoid any potential performance deterioration. Since the SQL Performance Analyzer is an integral part of the Oracle database, it can take advantage of tools such as the SQL Tuning Advisor as well as features such as SQL Plan Management to finetune database performance.

Multiple-column subqueries are queries where the inner query retrieves the values of more than one column. The rows in the subquery are then evaluated in the main query in pair-wise comparison, column by column and row by row.

m sure most of you are already familiar with SQL to some extent. However, I present in this appendix a quick introduction to Oracle Database 11g SQL and its programmatic cousin, PL/SQL, as a starting point for those new to programming Oracle databases. My goal here is simply to present a short summary of the classic DML and DDL commands and to discuss the newer SQL and PL/SQL concepts in greater detail. Your need to know SQL or PL/SQL depends somewhat on the type of DBA you are a production support DBA won t need to know as much about Oracle programming as a DBA assisting in developmental efforts. It s becoming increasingly important, however, for DBAs to learn a number of advanced SQL and PL/SQL concepts, including the new Java and XML-based technologies. The reason is simple: even when you aren t developing applications yourself, you re going to be assisting people who are doing so, and it helps to know what they re doing. This appendix aims to summarize some of the most important Oracle Database 11g SQL and PL/SQL features so you and the developers you work with can take advantage of them. Oracle SQL and PL/SQL represent an enormously broad topic, so this appendix lightly covers several important topics without attempting any detailed explanation due to space considerations. Please refer to the Oracle manuals Application Developer s Guide Fundamentals and PL/SQL User s Guide and Reference for a comprehensive introduction to SQL and PL/SQL.

Correlated subqueries are more complex than regular subqueries and answer questions such as What are the names of all employees whose salary is below the average salary of their department The inner query computes the average salary, and the outer or main query gets the employee information. However, for each employee in the main (outer) query, the inner query has to be computed, because department averages depend on the department number of the employee in the outer query.

If your database consists of large read-only tables, consider using the Oracle table compression feature to save storage space.

The EXISTS operator tests for the existence of rows in the inner query or subquery when you re using subqueries. The NOT EXISTS operator tests for the nonexistence of rows in the inner query. In the following statement, the EXISTS operator will be TRUE if the subquery returns at least one row: SQL> SELECT department_id FROM departments d WHERE EXISTS (SELECT * FROM employees e WHERE d.department_id = e.department_id);

Listing 7-2. Creating a Simple Table SQL> CREATE TABLE emp ( empno NUMBER(5) PRIMARY KEY, ename VARCHAR2(15) NOT NULL, ssn NUMBER(9), job VARCHAR2(10), mgr NUMBER(5), hiredate DATE DEFAULT (SYSDATE), sal NUMBER(7,2), comm NUMBER(7,2), deptno NUMBER(3) NOT NULL CONSTRAINT dept_fkey REFERENCES hr.dept(dept_id)) TABLESPACE admin_tbs01 SQL> In the CREATE TABLE statement in Listing 7-2, there are several integrity constraints, including a primary key and a foreign key defined on various columns of the table. Constraints are discussed in the Managing Database Integrity Constraints section, later in this chapter.
