Hi Duce

With MySQL, you use the LIMIT clause. You have to set the values for LIMIT in order to page through a recordset of results. There is an example on page 2 of the cheat sheet.

LIMIT 0, 10 < – returns the first 10 rows, starting with row #0
LIMIT 9, 10 <– returns the next 10 rows, starting with row #9

You are not paging through a record; you are paging through a recordset of multiple rows that are returned as query results.

The LIMIT clasue is commonly used to page through results from a SELECT query. I’ll include a better example in the next version and as soon as I find the time I will write a tutorial about paging through results with MySQL. Keep checking back. I will move the tutorial up to the top of my long list of tutorials that have not yet been written.

Thanks for this, it is most helpful.

There is just one command I do not seem to get right…

To scroll inside a record… On a unix system under normal command line I would use “| more”… How do I do this in MySQL?

Hi WFB

It will be in the next version, along with a lot of other suggestions that I have received. The next version should be ready soon.

Hi hotshot309

There are CSS, FileZilla and other cheat sheets in the works. All it takes it takes is the time that I don’t have right now. *sigh* :/

Thanks a lot for the great cheatsheet! I’m a beginner and will surely benefit from it. I’ll look out for an updated version.

Any other cheatsheets you’re considering adding?

Hi Jakob

After you drew attention to it, I recently run into a couple MySQL update scripts where the SET datatype was used. I may add it to the next version of the cheat sheet, and add a separate article explaining its use for those who are curious.

Thanks for the response.

a) sounds reasonable…
b) The fact that I mentioned the SET datatype is because I found your cheat sheet when I was looking for a concise overview of the MySQL Data Types. I was looking for an exhaustive list to quickly check I didn’t forget any datatype that my code could have problems with.

But I agree with you, for most applications the SET datatype is not practical – especially because it effectively stores data in the CREATE TABLE statements. And that totally goes against database normalisation.

Best Regards!
