What's the best way to manage tables or tabular data in HTML? Is there a fast way (app/plugin) to reorder rows/colums/etc. It seems very cumbersome to do by hand inside the code.
Thank you.
The easiest way to manage tables is by using an html editor such as Microsoft Expression Web or Adobe Dreamweaver.

I am dropping old tables from Redshift. Is it possible to search through all procedures to make sure a table is not referenced? It would be a lot easier than opening each one to search for text.
Thank you.
Consider using the unscanned_table_summary.sql query we provide on GitHub
Isn't there a way to list raw events from segment.com, with all their attributes, on Keen.io?
It seems the UI only allows me to create aggregations.
I believe you're looking for extractions. These will give you the raw data from whatever source they were given to. Keep in mind however, that the performance of an extraction will generally be slower than any other kind of query. Furthermore, doing too many of them can cause irate Keen engineers* to get on your case.
*In this case, probably me.
The easiest way to do this is to log into your Keen account and go to the Explorer. Click preview collections to pull up a schema inspector tool and sample events.
You can also run an extraction query in the explorer or any of the query SDKS. You can also easily download a CSV of your raw events.
Data Explorer Guide has more tips & tricks as well.
I am interested in creating a map of my database, so that I may understand it better. I am having difficulties understanding which tables relate to other tables, and I think a map, or flowchart would help me greatly. Has anyone done this? If so, how did you accomplish it?
You can try SQL Server Management Studio Express. Just right click on Database Diagrams and create a new diagram. You can select existing tables that you desire.
You can follow an excellent guide step by step here.
If you have Microsoft visio, that's a good software in creating a flowchart.
I use Lucid Chart (www.lucidchart.com) occasionally because we don't have Visio either. They offer a free account, which works pretty well, apart from the limit on the number of items you can put in one document (I want to say it's a limit of 60 entities).
I know this question has been up before but that was like three years ago and that's a lifetime :).
I'm using the twitter-bootstrap typeahead for autocomplete against mysql db with php, it works good right now. But I hit the db with a query every key-event, it doesn't feel like a good solution for a large scale application.
What's the best aproach here? Im thinking about memcache, but this is a dynamic db that will grow, how do I make sure that new information in the db get's cached to? I'm open for suggestions.
On Feb 2013 Twitter released typeahead (is not the bootstrap one),
it is s a powerful opensource lib for autocomplete, and one of his feature is:
Rate-limits network requests to lighten the load
I suggest you to give try.

For autocomplete it's possible use trigram matching.
Also you can use specialized fulltext search engines like Solr/Lucene or Sphinx.
Another alternative: switch to postgresql and use pg_trgm extension.
I am working on a web application, where we need to show more than 20,000 rows in a single page.
What is the best way to achieve this? As per requirements, we cant use pagination.
We are looking at options like Live Scrolling in Adobe Flex..is there any other framework that helps in doing this job efficient and easy?
I found this tutorial while surfing. i think this is just what you need :)
