Relational databases store data in rows because a typical SQL query looks for multiple fields within a record. For example, if you ask for name, zip code and email address of all your customers in New York, the result is presented in rows, with each row containing several fields from a single record. Row structures are also well optimized to handle a lot of inserts and updates.

But analytic queries are better handled with a column structure because they are more likely to go deep on a column of data, most queries relate only to a tiny subset of all the available columns and they’re also mostly read-only. For example, retrieving daily sales data for all your stores in California for the past two years is a columnar operation because it cuts across many records to retrieve data from a specific field. A typical ad-hoc aggregation query doesn’t care about most fields, just the trends in one …

While much less common than 10 or 15 (err… even 20) years ago, you still sometimes hear MySQL being called a “toy” database. The good news is, when somebody says that, they’re admitting ignorance and you can help educate them!

Recently, a fellow IBMer submitted a pull request (and bug) to start having MySQL support on Z Series (s390x).

Generally speaking, when there’s effort being spent on getting something to run on Z, it is in no way considered a toy by those who’ll end up using it.

We always need ask confirmation for remove items I mean we always ask before deleting items So if you need to ask confirm before do something like delete change status change value etc as you require If you want to do with better layout then you have to chooes bootboxjs and if you already use

One big drawback of Single-page application is the ability to fully support SEO as traditional sites. The reason is because in a single-page application we often use a technique called lazy-rendering, in which the real content is not rendered from the server but only the basic layout is returned. Many search engine crawls your websites similar to how you use "curl" command to fetch the content of the website, which prevents the search engine from understanding what is really inside the web page and it can not index the page correctly. In this post, I am going to show you how we can use PhantomJS to tackle this issue.

The main idea of this post is taken from this blog page: http://davidchin.me/blog/create-seo-friendly-angularjs-app/, you might want to read it for more information. I will explain it using my own words and this can apply to any single-page …

MariaDB works with many clients to migrate Microsoft SQL and Oracle to MariaDB. With the CONNECT storage engine we can access any ODBC data source in MariaDB. Here's a small HOWTO for those who want to give it a quick try. In this example we use MSSQL, though the same principle should be possible with Oracle ODBC servers.

We start with a clean MariaDB installation, no ODBC drivers installed yet. In this example we used CentOS7. It's important to start at a point where unixODBC is not yet installed, because the Microsoft installation package wants to install its own unixODBC.

Step 1

Microsoft is kind enough to supply us with an ODBC driver for Linux. We download it and unpack it.

Step 2 …

I am one of those crazy people who attempts to write SQL that works on SQlite, MySQL and PostgreSQL. First I should explain why:

This is all for my project sabre/dav. sabre/dav is a server for CalDAV, CardDAV and WebDAV. One of the big design goals is that it this project has to be a library first, and should be easily integratable into existing applications.

To do this effectively, it’s important that it’s largely agnostic to the host platform, and one of the best ways (in my opinion) to achieve that is to have as little dependencies as possible. Adding dependencies such as Doctrine is a great idea for applications or more opinionated frameworks, but for …
