In SQL Server, the T-SQL CEILING() function allows you to round a number up to the nearest integer. More specifically, it returns the smallest integer greater than, or equal to, the specified numeric expression.
You provide the number as an argument. The return data type is the same as the one provided as an argument.
In SQL Server, the ATN2() function returns the arctangent between two values. Specifically, it returns the angle, in radians, between the positive x-axis and the ray from the origin to the point (y, x), where x and y are the values of the two specified float expressions.
You provide the values as arguments when calling the function.
In SQL Server, the ATAN() function returns the arctangent of a value. In other words, it returns the angle, in radians, whose tangent is a specified float expression.
You provide the value as an argument when calling the function.
Using SQL Server, you can use the T-SQL ASIN() function to return the arcsine of a number. In other words, this function returns the angle, in radians, whose sine is the specified float expression.
The return data type is float.
You provide the number as an argument when calling the function.
Using SQL Server, you can use the T-SQL ACOS() function to return the arccosine of a number. In other words, this function returns the angle, in radians, whose cosine is the specified float expression.
The return data type is float.
You provide the number as an argument when calling the function.
In SQL Server, the ABS() function returns the absolute value of a specified value.
You provide the value as an argument. The return value is of the same type as the argument.
An absolute value is the distance of a number on the number line from 0 without considering which direction from zero the number lies. Therefore, the absolute value of a number is always a non-negative value (i.e. it’s never negative).
If you’ve been using the JSON_MODIFY() function to modify JSON documents in SQL Server, you might be used to modifying the value part of a key/value property. But did you know that you can also modify the key part?
The trick to doing this is to copy the value to a new key, then delete the old key.
Examples below.
In SQL Server, you can use the T-SQLÂ JSON_MODIFY() function to modify the value of a property in a JSON string. The function returns the updated JSON string.
Two of the many T-SQL functions available in SQL Server are JSON_QUERY() and JSON_VALUE(). These functions can be used to extract data from JSON documents.
Their general syntax is similar, and at first glance, you might think they do exactly the same thing, but they don’t. There’s definitely a place for both functions when working with JSON and SQL Server.
This article looks at the difference between JSON_QUERY() and JSON_VALUE().
When using JSON with SQL Server, you can use the JSON_QUERY() function to extract an object or an array from a JSON string.
To use this function, you provide the JSON expression as an argument. You can also provide a second (optional) argument to specify the object or array to extract.
