Which One Will Delete the Table Data as Well as Table Structure Examveda?


Heather Bennett

When it comes to deleting table data in SQL, there are a few options available. However, if you want to delete both the table data and the table structure itself, there are two commands that can help you achieve this: DROP TABLE and TRUNCATE TABLE. Let’s take a closer look at each of these commands and understand their differences.


The DROP TABLE command is used to remove an entire table from the database. This not only deletes all the data within the table but also removes the table structure itself. The syntax for using this command is as follows:

DROP TABLE table_name;

Here, table_name refers to the name of the table you want to delete. It’s important to note that once a table is dropped using this command, all data contained within it will be permanently lost. Therefore, exercise caution while using this command and ensure that you have a backup of your data.


The TRUNCATE TABLE command is another option for deleting both the data and structure of a table. However, unlike DROP TABLE, this command does not permanently remove the table itself.

Instead, it removes all rows from the specified table while keeping its structure intact. The syntax for using this command is as follows:

TRUNCATE TABLE table_name;

In this case, table_name indicates the name of the table you wish to truncate. Similar to DROP TABLE, be cautious when using this command as all data within the specified table will be deleted without any possibility of recovery.

Key Differences

While both DROP TABLE and TRUNCATE TABLE can delete table data as well as the table structure, there are a few notable differences between them:

  • DROP TABLE permanently removes the table from the database, whereas TRUNCATE TABLE only deletes the data within the table.
  • DROP TABLE cannot be rolled back, while TRUNCATE TABLE can be undone using a transaction.
  • DROP TABLE triggers various events such as deleting indexes, constraints, and triggers associated with the table, while TRUNCATE TABLE does not have these effects.
  • DROP TABLE requires more privileges compared to TRUNCATE TABLE. Typically, only database administrators have the authority to execute the DROP command.

In conclusion, both DROP TABLE and TRUNCATE TABLE can effectively delete table data along with its structure. However, it’s important to consider your specific requirements and exercise caution when choosing between these commands. Always ensure that you have a backup of your data before executing any potentially destructive SQL commands.

I hope this article has provided you with a clear understanding of how to delete both table data and structure in SQL using the appropriate commands. Happy coding!
