MySQL Truncate Table statement removes all the records or complete data without affecting the table structure or indexes. When you want to remove all the existing records, then the MySQL Truncate Table statement is the best option for you and the basic syntax of it is
TRUNCATE TABLE `Schema_Name`.`Table_Name`
We are going to use the following to demonstrate this MySQL Truncate table.

MySQL Truncate Table Example
In this MySQL Truncate Table example, we are going to clear the above-specified.
TRUNCATE TABLE sqltest.empdetails;

Let us see the data in the above
SELECT EmpID, `FirstName`, `LastName`,Education, Occupation, YearlyIncome, Sales, HireDate FROM empdetails;

As you can see, it returned 0 records.
By viewing the above MySQL results, you might wonder why we need Truncate when the Delete Statement without Where Clause can do similarly?.
- Well, it automatically reset the AUTO_INCREMENT counter to the starting point, which is not the possible case for Delete statement.
- This statement drops the existing table and recreates the same. Because of this, any Delete triggers won’t fire during this process.
It is another example of it using the command prompt or Terminal.
TRUNCATE TABLE sqltest.employeedetails;

Using Workbench

MySQL Truncate all Tables
In MySQL, you can use the information_schema to get all the tables in a Database. From there, you can remove the required ones.
For instance, the below query returns all the available ones in a database. It is instrumental in finding the list of tables available for you. Then perform the required operations on them.
SELECT TABLE_NAME FROM information_schema.tables WHERE table_schema = 'sqltest'

Next, you can use the this statement to clear one after the other.
TRUNCATE TABLE department
Or, You can use the below code to generate a statement to delete all of them in the database.
SELECT CONCAT('TRUNCATe TABLE ' , TABLE_NAME ) FROM information_schema.tables WHERE table_schema = 'sqltest'
The above code returns the truncate statement for all of them. You can simply copy and execute those codes.
