In SQL Server, you can use the ROWCOUNT_BIG() system function to return the number of rows affected by the last T-SQL statement.
It works exactly the same as @@ROWCOUNT, except that ROWCOUNT_BIG() returns its result as a bigint.

SQL Server SHOWPLAN_ALL
In SQL Server, you can use the SET SHOWPLAN_ALL statement to return the query plan for a given T-SQL statement. The query plan displays detailed information about how the statement is executed, as well as estimates of the resource requirements for the statements.
SQL Server SHOWPLAN_TEXT
In SQL Server, you can use the SET SHOWPLAN_TEXT statement to return the query plan for a T-SQL statement. This contains detailed information about how the statement is executed.
Database Mail Tutorials
I’ve written quite a number of tutorials for using Database Mail, and I’ve created this article to list them all in one place.
I first included these links at the bottom of How to Send Emails from SQL Server (T-SQL), but I thought it might be helpful to move them to their own article as a quick-reference.
What Do I Need to Run SQL?
I get it. You’re trying to learn SQL, but they won’t even tell you the most fundamental part – what you need to run SQL!

SQL Server CASE Expression
In SQL Server, the T-SQL CASE expression is a scalar expression that returns a value based on conditional logic. It evaluates a list of conditions and returns a value, based on the outcome of those conditions..

Install PostgreSQL on Ubuntu 20.04

Yes, that means that your Ubuntu 20.04 installation probably already has a PostgreSQL package sitting there waiting for you to install it.
And you can install it with one command, which I’ll show you below.
But what if you prefer to run the latest version of Postgres instead? Well, I’ll also show you how to install that. Installing the latest version is almost as easy as installing your local package.
Install PostgreSQL on Ubuntu 18.04
The following steps demonstrate how to install PostgresSQL on Ubuntu 18.04.
There are a couple of ways to go about installing Postgres on Ubuntu.
But before we start jumping in and installing it, did you know that by default, PostgreSQL is already available in Ubuntu 18.04?
So one option is to go right ahead and use the version that’s already included with Ubuntu.
But unless you have reason not to, you will probably want to run the latest version of PostgreSQL, in which case you’ll want to download and install the latest version.
This tutorial covers both options.
