Use the CHARINDEX function multiple times to show the number of characters between two words in a text string

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.

Before you can do this exercise, you'll need to download and unzip this file . Once you've done this:

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).

The aim of this exercise is to find this and that in the EventDetails column (in that order). Your final query should show this:

There are 3 rows containing both words, but these are the only 2 containing them in the right order.

You should find the CHARINDEX function useful. Here's an example:

CHARINDEX( 'Trump', 'Donald Trump', 1)

This would return 8, since Trump begins in Donald Trump at the 8th character (starting from 1).

When you've got this working (and it's fiddly), save this as This and that, then close it down.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.

How did you resist to the temptation of looking for this, that and the other ? #Seinfield Why is there HTML code in this screen ? And no preview mode ? So many questions, so many answers. Thanks.

Hi! The visible HTML is a small issue related to the redesign of the website. Thanks for pointing it out - it should be resolved soon!

Query_Sol. for MySQL users

-- In MySQL, the equivalent function to the CHARINDEX is LOCATE

SELECT EventName, EventDate,
   LOCATE('this', EventDetails) AS thisPosition,
   LOCATE('that', EventDetails) AS thatPosition,
   (LOCATE('that', EventDetails) - LOCATE('this', EventDetails)) AS 'Offset'
FROM tblevent
WHERE
   LOCATE('this', EventDetails) > 0
   AND LOCATE('that', EventDetails) > 0
   AND LOCATE('that', EventDetails) > LOCATE('this', EventDetails);
