Databases are platforms that are designed to securely store and retrieve your data. Perhaps that’s why they’re called a data “base”? So if your data is in a base, you’d want to lay it out in some logic way.
SARG is short for Search Argument. This is an important tuning term and something every developer and DBA should know. I plan to do a few blogs on this topic and today marks the first.
Continuing the comparison between these two database giants, we dive into the substring function. If you’ve been working with databases for a while, I’m sure you’ve had to parse a string and while you’d think these are the same they work a little different and I think Oracle may surprise you a bit.
It’s Wednesday and that means another SQL/Oracle post. Today we’ll be discussing NULL Values, which can sometimes be a real pain. Don’t worry though there’s a simple solution. Simply replace the NULL value with another.
Today’s topic is Pagination. Paging is a really important feature for web pages and applications. Without it you’d be passing large amounts of data to the application and expecting the application code to figure out which rows it needed to display.
In today’s continuation of the SQL / Oracle series, I thought it’d be nice to show how different the two are for retrieving the top number of rows.
Continuing my series on SQL Server and Oracle, I thought I’d highlight a function that has been in Oracle from some time and has only just recently appeared in SQL Server.
Are you a DBA and just inherited a SQL Server or Oracle database? Are you migrating from one or the other? I’ve decided to start a series comparing these two RDBMS giants and the first topic is date formatting.
