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.
12 Commonly Used SQL Operators
In SQL, an operator is a special character or keyword specifying an action that is performed on one or more expressions.
SQL operators are an integral part of SQL, and they enable us to write queries that return relevant results.
In this article, I present 12 of the most commonly used SQL operators when writing SQL queries.
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!
You’ve got the SQL code… but where do you actually run it? What software program do you need before you can run your SQL query against a database?
If that’s you, all is about to be revealed!
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..
In some ways, the SQL Server CASE expression is similar to IF...ELSE. However, CASE allows you to check for multiple conditions, whereas IF...ELSE doesn’t.
How to Select Nested JSON in SQL Server with OPENJSON
If you’re using OPENJSON(), but you’re trying to remember how to select an inner fragment from the JSON document, read on.
How to Write an ORDER BY Clause with Exceptions using SQL
In SQL, the ORDER BY clause is commonly used to order the results of a query. It allows you to select one or more columns to order the results, and in most cases, it’s probably all you need.
But what if you need to make an exception?
What if you want the results to be ordered alphabetically, except for one row? Or several rows?
Or perhaps you simply want to put any NULL values to the end, while ordering the non-NULL results.
Either way, there’s a neat trick you can use that will enable you to do this. And the good part is, it’s simple.
You can cater for all of the above scenarios by adding a CASE expression to your ORDER BY clause.
