Azure Data Studio (previously known as SQL Operations Studio) is a free tool that you can use to manage SQL Server. It uses a graphical user interface (GUI) that helps you view the various databases and objects within a SQL Server instance. It can run on Windows, macOS, and Linux, and it’s also designed to be used with Azure SQL Database, and Azure SQL Data Warehouse.
Here I explain how to install Azure Data Studio onto a Mac, then how to use it to connect to SQL Server.
Microsoft Azure Data Studio is a free, cross-platform tool that can be used to manage SQL Server, Azure SQL Database, and Azure SQL Data Warehouse.
Azure Data Studio was formerly called SQL Operations Studio (while it was in preview release), and it was renamed to Azure Data Studio once it was moved to general availability (GA) on September 24, 2018.
Transact-SQL contains a number of mathematical functions that you can use with SQL Server.
The following scalar functions can be used in SQL Server 2012 and above. Most of these functions accept one or more arguments, and will return a numeric value based on the argument/s supplied.
In SQL Server, the TAN() function returns the tangent of the input expression.
You provide the value as an argument when calling the function.
Using SQL Server, you can use the T-SQL SQUARE() function to return the square of a specified float value. The square of a number is the result of multiplying the number by itself.
You provide the number as an argument when calling the function.
The return data type is float.
Using SQL Server, you can use the T-SQL SQRT() function to return the square root of a specified float value.
You provide the number as an argument when calling the function.
The return data type is float.
Using SQL Server, you can use the T-SQL SIN() function to return the sine of a number. More specifically, this function returns the trigonometric sine of the specified angle, in radians, and in an approximate numeric, float, expression.
The return data type is float.
You provide the number as an argument when calling the function.
In SQL Server, the T-SQL SIGN() function returns the sign of a number. In other words, it indicates whether or not the value is a positive number, a negative number, or zero.
You provide the number as an argument when calling the function.
The function returns the following result, depending on whether the argument is positive, negative, or zero.
In SQL Server, the T-SQL ROUND() function allows you to round a number to a specified length or precision.
You provide the number as an argument, as well as the length you’d like the number to be rounded to. The function also accepts an optional third argument that allows you to specify whether the number is rounded or truncated.
In SQL Server, the T-SQL RAND() function allows you to generate a random number. Specifically, it returns a pseudo-random float value from 0 through 1, exclusive.
The function accepts an optional argument which provides the seed value. For any given seed value, the results will always be the same.
