What Topics Are Covered on the Oracle SQL Exam?
The Oracle 1Z0-071 exam is notoriously rigorous. It does not just test your ability to write basic SQL queries; it evaluates your deep understanding of how the Oracle Database engine processes data. To estimate your required study time accurately, you must audit your current knowledge against the official exam domains.
The syllabus is broadly categorized into the following technical areas:
1. Relational Database Concepts
You must understand the theoretical foundation of relational database management systems (RDBMS), including Entity Relationship Diagrams (ERD), primary and foreign keys, and data normalization.
2. Retrieving Data Using the SQL SELECT Statement
This covers the absolute basics: writing a basic SELECT statement, selecting all columns, selecting specific columns, using column aliases, and understanding the DUAL table in Oracle.
3. Restricting and Sorting Data
You will be tested on filtering rows using the WHERE clause, applying comparison operators (=, >, <, IN, LIKE, BETWEEN), logical operators (AND, OR, NOT), and sorting data using the ORDER BY clause.
4. Single-Row Functions and Conversion Functions
Oracle SQL relies heavily on built-in functions. You must master character functions (UPPER, LOWER, SUBSTR, INSTR), number functions (ROUND, TRUNC), and date functions. Furthermore, understanding implicit and explicit data type conversion using TO_CHAR, TO_NUMBER, and TO_DATE is mandatory.
5. Grouping and Aggregating Data
This domain tests your ability to use group functions like COUNT, MAX, MIN, SUM, and AVG. You must also know how to group data using the GROUP BY clause and restrict grouped results using the HAVING clause.
6. Displaying Data from Multiple Tables (Joins)
You must understand how to write equijoins, non-equijoins, OUTER joins (Left, Right, and Full), CROSS joins, and NATURAL joins using the ANSI SQL:1999 syntax.
7. Using Subqueries and Set Operators
This is often where candidates lose the most points. You need to understand single-row subqueries, multiple-row subqueries, and correlated subqueries. Additionally, you must know how to combine multiple queries using set operators (UNION, UNION ALL, INTERSECT, MINUS).
8. Data Manipulation Language (DML) and Data Definition Language (DDL)
You must know how to modify data using INSERT, UPDATE, DELETE, and MERGE statements, as well as manage database transactions using COMMIT, ROLLBACK, and SAVEPOINT. Furthermore, you will be tested on creating, altering, and dropping tables using DDL statements, and managing constraints.
9. Managing Schema Objects and User Access
Finally, the exam covers the creation and management of other schema objects like views, sequences, synonyms, and indexes. You must also understand basic Data Control Language (DCL), specifically granting and revoking system and object privileges.

Common Mistakes to Avoid During Your Exam Prep
Many candidates fail the Oracle 1Z0-071 exam not because they lack knowledge, but because they fall into predictable traps during their study phase. Avoid these common pitfalls:
- Relying Only on Theory: Reading a textbook will not help you pass. Oracle exams feature complex blocks of SQL code. You must type out queries, make syntax errors, and learn how to fix them in a real database environment.
- Ignoring Default Behaviors: The exam loves to test what happens when you don’t specify a parameter. For example, what is the default sort order of an ORDER BY clause? (Answer: Ascending). Where do NULL values appear in an ascending sort by default? (Answer: At the bottom).
- Neglecting Date Functions: Many candidates breeze past data conversion. You must deeply understand how TO_CHAR and TO_DATE work with specific format models like DD-MON-YYYY or RR.
- Underestimating Time Management: You have 120 minutes to answer 78 questions. That is roughly 1.5 minutes per question. If you haven’t taken timed practice tests, you run a high risk of failing to complete the exam.
