Not sure if we deserve all the reviews you can see on this site? Here are some of the things we do (very) differently to earn them.
How can any training company guarantee the quality of their courses? Here's how:
Our course manuals and exercises are by some way the best in the computer training industry. Fortunately you don't have to take our word for this - you can see for yourself:
Our values are simple - we treat people as we would like to be treated ourselves. So:

We've put a lot of thought into making our online courses as useful and interactive as possbile:

Can't see the dates/course type that you want? Create your own onsite course (and tailor the content too!).
Courses marked with an (*) are new courses (for these courses our usual no cancel guarantee doesn't apply).
If you can't see the course you want listed above, don't despair! If you can muster 3 or 4 people together, it may well be worth organising an onsite course at your office (we'll provide and set up the computers), or else an online course tailored to your needs.
Here are some comments we've received about our SQL + training. You can see all of our 519 reviews here. We would like to sincerely thank the clients whose names are shown below for kindly agreeing to let us share their feedback.
"The course content and the exercises were really helpful. The trainer went through it at a very good pace and explained things very clearly. Course content was clear and well-priced for a 2-day course."

"Great trainer. Pace of course was brilliant and learnt a lot. Really useful for expanding my skill set."
Kristin McIntosh

"I thought the course was superb. The content delivery and the accessibility to all was really impressive, having the exercises to work through during the course helped consolidate the knowledge. The content was really easy to follow and if we were ever stuck, were given the confidence to feel like we could ask for help. I have been on multiple different training courses with different providers and I can honestly say the course was delivered by the best trainer I have ever had. The passion he has for teaching and helping others learn was clearly on show and was so refreshing and great to see. Throughout both days he made you feel so welcome and that no question was a stupid question, he was always there to help and guide you through any problems we had and overall he was just amazing, I couldn't have asked for any more and he went above and beyond my expectations for the course and what I would gain from it.

Sick of having to contact your IT people or third party supplier to get at your own data? Learn to write queries to get at it yourself, using either SQL Server Management Studio or (by request) Azure Data Studio. We run two scheduled courses: a two-day introduction to SQL course, and a two-day advanced SQL course.
If you're a quick learner you could consider combining these two courses together and attending our single three-day fast-track course (but only if you're a quick learner).
This course will show you how to write queries like the one below using T-SQL, the dialect of SQL used within Microsoft's SQL Server:
-- show how many films there are for each certificate
SELECT
c.Certificate,
COUNT(*) as 'Number of films'
FROM
Film as f
INNER JOIN Certificate AS c
ON f.CertificateID = c.CertificateID
GROUP BY
c.Certificate
ORDER BY
-- show most popular certificate first
'Number of films' DESC
This won't necessarily make much sense to you now, but it will do after the course!
This course assumes that you know how to write queries, and shows you how to program in SQL, including using variables, writing stored procedures and functions and using table variables and temporary tables. Here's a sample of what you'll learn to do:
CREATE PROC spListFilms(
@minOscars int,
@maxOscars int
)
AS
-- list films winning this many Oscars
SELECT
f.Title,
f.OscarWins
FROM
Film AS f
WHERE
f.OscarWins between @minOscars and @maxOscars
Still not sure which is the right course for you? There's more help available here.
Finally, note that we're also big believers in teaching you not just how to write queries, but how to write them well, following our own internal SQL coding standards.
