Result Table - Selected values are now Edit Based on the additional screenshots you provided, the issue is clear.All scalar data types in Kusto have a special value that represents a missing value. This value is called the null valueor simply null. The null value of a scalar type T is represented in the query language by the null literal T null. Thus, the following returns a single row full of nulls:. The null value does not compare equal to any other value of the data type, including itself. To determine if some value is the null value, use the isnull function and the isnotnull function.
In general, null behaves in a "sticky" way around binary operators; a binary operation between a null value and any other value including another null value produces a null value. For most data types, a missing value in the data source produces a null value in the corresponding table cell. An exception to that are columns of type string and CSV-like ingestion, where a missing value produces an empty string.

Sometimes you want to replace them with some other quantity. This short blog post shows you through example how to replace missing values with zero in SAS. First of all, let us create some small example data set.
The code below creates a SAS data set with five observations and quite a few missing values. I will use this data set in the examples to come.
First off, let us look at an example of replacing the missing values with a simple Data Step. After reading in the data set above, I create an Implicit Array NumVar to hold all numeric variables in the data set.
Next, I loop over all objects in the NumVar array and use simple if-then logic to set missing values to zero. An easy to understand approach to a simple data problem.
Furthermore, you can easily modify the code to replace missing values for only the desired variables by inserting only those variables into the array. Even though the data step method above works just fine, there is a simpler way.
Furthermore, it does so with much less coding than in the data step example. This option ensures that we are only to replace missing values and nothing else. If we omit this option, missing values are replaced by the location measure by default. In the above example, we replace with zero for all numeric variables.
However, it can be convenient to replace missing values for specific variables only. To do this, simply specify the relevant variables in the var statement as below.
I encourage you to run the above code examples and see how the data sets differ. And can you set this option to other quantities that make sense? Missing values are part of the data game. And you should be careful how you treat these. You should only replace them with other quantities if it makes sense. For example, you should only replace a missing value with a zero, if the lack of this value actually implies a lack of the particular variable value. Zeros are not the only values that make sense to insert instead of missing values.
But there is no string null. The closest to string is guid, but when I use it in the following manner, I get an error If you execute this, you can see that empty strings are being considered as part of sets. I don't want this, no such empty strings should be part of my array.
But at the same time I don't want to lose value of n, and this is exactly what will happen if I if I use isnotempty function. I'm pretty certain that in itself, that shouldn't block you from reaching your end goal, but that goal isn't currently clear. Learn more.
