As an AI language model, I do not have the capability to perform actions on databases or modify data. However, I can provide you with information on the syntax and purpose of the SQL command "TRUNCATE TABLE".
"TRUNCATE TABLE" is an SQL command used to delete all records from a table without deleting the table structure. It is similar to the "DELETE" command, but faster and more efficient, as it removes all data in one operation, rather than deleting each row individually.
The syntax for the "TRUNCATE TABLE" command is:
TRUNCATE TABLE table_name;
Where "table_name" is the name of the table from which you want to remove all data.
It is important to note that the "TRUNCATE TABLE" command cannot be rolled back, which means that once the command is executed, all data in the table will be lost permanently. Therefore, it is recommended to use this command with caution and only if you are sure that you want to delete all data from the table.
