Overview of Trigger Interview Process
The trigger interview process is a type of job interview that provides employers with a structured approach to assess the suitability of a candidate for a particular role. This type of interview is particularly helpful when employers need to make a fast, informed decision about a job applicant. The trigger interview process consists of a series of questions or topics that the employer can use to assess a candidate’s skills, experience, and qualifications.
The trigger interview process typically begins with a short introduction by the employer that outlines the overall objectives of the interview. Following the introduction, the employer will ask a series of questions that are designed to elicit specific information about the candidate’s qualifications, experience, and abilities. For example, the employer may ask questions about the candidate’s past experience and successes, as well as their preferred working style and capabilities. Through this process, employers can quickly gain an accurate understanding of the candidate’s skills and qualifications and determine whether they are a suitable fit for the role.
In addition to asking questions, employers may also use the trigger interview process to assess how well the candidate communicates, thinks on their feet, and deals with pressure. For instance, the employer may ask challenging questions that require the candidate to think quickly and demonstrate their problem- solving skills. This type of questioning allows employers to gain insight into the candidate’s personality and ability to perform under pressure.
The trigger interview process is an effective way to quickly and efficiently assess job candidates. By utilizing the structured approach of the trigger interview, employers can gain an accurate understanding of the candidate’s qualifications, experience, and abilities. Additionally, employers can assess how well a candidate communicates and performs under pressure. Ultimately, the trigger interview process can provide employers with the information they need to make the best decision for their organization.

Top 20 Trigger Interview Questions and Answers
1. What is a Trigger?
A trigger is a piece of code that is executed automatically in response to a specific event, such as an update, delete, or insert operation on a table in a database. Triggers can be used to enforce data integrity, maintain data security, and enforce business rules. For example, a trigger could be used to check the values of a new record before it is inserted into a table, or to update related records when a record is modified.
2. What are the benefits of using triggers?
Triggers can provide a number of benefits and advantages to an application. They can help enforce data integrity by preventing unauthorized changes to data and ensuring data is stored in a consistent format. They can also improve data security by preventing unauthorized access to data. Triggers can also automate tasks that would otherwise be manual and time consuming. For example, an update trigger could be used to automatically update related records when a main record is changed.
3. What is the difference between a stored procedure and a trigger?
The main difference between a stored procedure and a trigger is that a stored procedure is a user-defined block of code that can be executed directly by the user, while a trigger is a piece of code that is executed automatically in response to a specific event. A stored procedure will execute when it is called while a trigger will execute when the event it is defined to respond to is triggered.
4. What are the different types of triggers?
The different types of triggers include:
- Insert triggers, which are executed when a record is inserted into a table.
- Update triggers, which are executed when a record is updated.
- Delete triggers, which are executed when a record is deleted.
- Instead of triggers, which are executed instead of an insert, update, or delete statement.
- DDL triggers, which are executed in response to a data definition language (DDL) statement.
5. How do you create a trigger?
Triggers can be created using the CREATE TRIGGER statement in the SQL language. This statement requires the name of the trigger, the table it is associated with, the type of trigger (insert, update, delete, etc.), and the code to be executed when the trigger is activated.
6. What is a trigger body?
The trigger body is the code that will be executed when the trigger is activated. This code can include any valid SQL statement or a series of SQL statements. The trigger body can also include variables, conditions, and other operations.
7. What are the types of triggers in SQL?
The types of triggers in SQL include:
- Insert triggers
- Update triggers
- Delete triggers
- Instead of triggers
- DDL triggers
8. What is the purpose of a trigger?
The purpose of a trigger is to automatically execute a piece of code in response to a specific event. Triggers can be used to enforce data integrity, maintain data security, and enforce business rules. For example, a trigger could be used to check the values of a new record before it is inserted into a table, or to update related records when a record is modified.
9. How do you test a trigger?
Triggers can be tested by executing the trigger manually and inspecting the results. This can be done by executing the code in the trigger body directly or by manually executing the event the trigger is associated with (such as an insert, update, or delete).
10. What are the disadvantages of using triggers?
The main disadvantage of using triggers is that they can slow down the performance of the database if they are not written or used correctly. Triggers can also be difficult to debug and maintain as they are executed automatically and not immediately visible when troubleshooting.
11. What is a cascade trigger?
A cascade trigger is a trigger that is triggered in response to another trigger being activated. For example, if an update trigger is activated, a cascade trigger can be used to automatically update related records when the update trigger is activated.
12. What is the difference between a trigger and an event?
The main difference between a trigger and an event is that a trigger is a piece of code that is executed automatically in response to a specific event, while an event is an occurrence that is recognized by the database. A trigger must be associated with an event in order to be executed.
13. How do you enable or disable a trigger?
Triggers can be enabled or disabled using the ALTER TRIGGER statement in the SQL language. This statement requires the name of the trigger and the option to enable or disable it.
14. What are the different types of events a trigger can respond to?
Triggers can be used to respond to a number of different events, including:
- DDL statements
- Database events
- Schema events
- System events
15. What are the advantages of using triggers?
The advantages of using triggers include:
- Enforcing data integrity.
- Automating tasks that would otherwise be manual and time consuming.
- Improving data security by preventing unauthorized access to data.
- Improving performance by executing code only when necessary.
16. What is the syntax for creating a trigger?
The syntax for creating a trigger is as follows:
CREATE TRIGGER [trigger_name]
17. What is a AFTER trigger?
A AFTER trigger is a type of trigger that is executed after the event it is associated with occurs. For example, an AFTER trigger could be used to automatically update related records when an insert or update statement is executed.
18. What is an INSTEAD OF trigger?
An INSTEAD OF trigger is a type of trigger that is executed instead of the event it is associated with. For example, an INSTEAD OF trigger could be used to prevent a delete statement from being executed on a specific table.
19. What are the components of a trigger?
The components of a trigger include:
- The trigger name.
- The table the trigger is associated with.
- The type of trigger (insert, update, delete, etc.).
- The code to be executed when the trigger is activated (the trigger body).
20. What is a BEFORE trigger?
A BEFORE trigger is a type of trigger that is executed before the event it is associated with occurs. For example, a BEFORE trigger could be used to check the values of a new record before it is inserted into a table.
