Oracle Developer Interview Questions
Question: Can you provide an overview of Oracle?
The interviewer will ask this usual opening or general question to start the conversation, find out more about your background, and get some information they can use for other questions they will ask.
Example: “Oracle is one of the more popular databases and was developed by the Oracle Corporation. It is the foundation for other applications developed by both Oracle and third parties. Since it uses relational management concepts, it is referred to as a relational database management system or RDBMS. Some of its applications include online transaction processing, data warehousing, and enterprise computing. ”.
Question: What is the nomenclature used to identify Oracle database software releases?
Explanation: This is a technical question. As an Oracle developer, you can expect that technical and operational questions will make up most of the interview. These are best responded to briefly and directly with little embellishment. The interviewer will ask a follow-up question if they need additional information.
Example: “Oracle has a specific nomenclature which they use for each release of the Oracle database software. This helps developers as well as users identify which version of the software they are working with. A typical format is release 10. 1. 0. 1. 1. Each of these numbers has a specific meaning which are:
- 10: major DB release number
- 1: DB maintenance release number
- 0: application server release number
- 1: component-specific release number
- 1: platform-specific release number”
Question: What process is used to create privileges in Oracle?
Explanation: This is an operational question. Much like technical questions, operational questions explore your knowledge and skills within the Oracle developer profession. Operational questions seek to understand how you go about doing your job.
Some examples of privileges in Oracle are the ability to run queries and get to other database objects. The two classes of privileges include user system privilege. The system privilege provides greater access to the database and the ability to do more. Privileges are assigned using the following command string:
[sql]GRANT user1 TO user2 WITH MANAGER OPTION;[/sql]”
Question: Could you explain what the term “VArray” means in Oracle and how it is used?
This is a technical question that asks you to define a word and then talk about how it is used in the job you are interviewing for. This is the typical structure of a technical question. Remember to keep your answer short and to the point. The interviewer will ask a follow-up question if they need additional information.
Example: “VArray is a data type used by Oracle to enable columns to contain multivalued attributes. It can also hold a bounded array of values. ”.
Question: What command is used to obtain the details of the fields in a table?
Explanation: This question asks for a specific command to accomplish the task defined in the question. You answer this question by stating that command and then describing what it does.
Example: “The command used to get the details of fields of a specified table is describe.”
Question: Can you discuss the differences between the rename and alias commands in Oracle?
Explanation: This question asks you to compare two similar but different commands within Oracle. To answer this question best, you should first explain what each word means and then talk about what it does or how it falls short.
Example: “Both rename and alias are commands used to name a table or column within Oracle. The main difference is that alias gives the table or column a different name while keeping the original one, while rename gives these things a permanent name that replaces the current one. ”.
Question: How do you differentiate between VARCHAR and VARCHAR2?
Explanation: Here is another technical question asking you to define the differences between two similar terms. Once more, begin your answer by explaining what the terms mean and what they do. Then, quickly go over the differences between them.
Example: “Both VARCHAR and VARCHAR2 are Oracle data types used to store character strings of variable length. One difference between them is VARCHAR2 can store twice the number of bytes as VARCHAR, 4000 vs. 2000. Also, VARCHAR will keep a space for characters that were declared but aren’t used, while VARCHAR2 will free up any space that isn’t being used. ”.
Question: What are the differences between Oracle’s TRUNCATE and DELETE commands?
Explanation: This is another technical question asking you to distinguish between two different commands within Oracle. As the interview progresses, the questions will become more specific and more difficult. This indicates the interviewer is gaining confidence in your abilities and is willing to explore more complex topics. Continue to answer these questions just as you did the easier ones.
Example: “Both the TRUNCATE and DELETE are commands used to delete data from the database. The differences between these two similar commands are:
It is not possible to undo the TRUNCATE command, but it is possible to undo the DELETE command.
DELETE is a DML operation, and TRUNCATE is a DDL operation.
TRUNCATE frees the object’s storage space, but DELETE does not.”
Question: Can you describe what a RAW datatype is and how it is used?
This is a typical technical question where you have to first explain what a word means and then explain how it is used. As mentioned before, technical questions should be answered briefly and directly. You should anticipate a follow-up question any time you respond to a technical question. This will indicate the interviewer either needs more information or has a specific interest in this topic.
Example: “A RAW datatype is used to store variable-length binary data or byte strings. When RAW data is sent to a different system, SQL can’t convert it because it doesn’t know this type of data. Also, RAW data types can only be queried or inserted in a table. ”.
What does the word “joins” mean in Oracle? Could you name a few different kinds of joins?
Explanation: The interviewer is continuing to ask you technical questions. The best way to get ready for an interview as an Oracle developer is to first read the job posting and make a list of the requirements for the job. You should then research the company, its products, and the software it develops. This will give you an idea of the type of methodologies, commands, processes, and procedures they use. Once you know these, refresh yourself on typical Oracle terms, development methodologies, and commands.
Example: “Within Oracle, joins are used to extract data from multiple tables using common columns or conditions. The different types of joins include inner, outer, cross, equi, anti, and semi. ”.
