SQL | Transactions exercise | Creating transaction with an insert command
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
The answer to the exercise will be included and explained if you attend the course listed below!
- Go into SQL Server Management Studio;
- Open the SQL file you've just unzipped (you can press CTRL + O to do this); then
- Execute this script.
This will generate the database that you'll need to use in order to do this exercise (note that the database and script are only to be used for exercises published on this website, and may not be reused or distributed in any form without the prior written permission of Wise Owl).
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop.

Write an insert statement to add a new event with EventName called My DOB , with your date of birth as the Eventdate column and an appropriate entry for the EventDetails column:
Remember INSERT INTO tblEvent and VALUES.
Now we can turn this insert into a transaction - but first, write a delete command to remove any events with an Eventname like My DOB.
DELETE FROM tblEvent WHERE EventName LIKE 'My DOB'
Create a transaction which tests if an Eventname of My DOB exists already, adding it if it doesn't and giving a message if it does:
Results of running the script for the first and second times. Your EventID will be different!
Optionally save this as Adding dates of import.sql then close it down.
