Kusto Query Builder

Kusto Query Builder is a powerful query builder for the Kusto query language written in C#. It was inspired by the SqlKata project.

It provides a fluent based API for building Kusto queries in code. Currently, it supports the following expressions:

• Project
• Where, including where between and where in
• Order by ascending and descending

Examples

Create a query

var qry = new Query("Table");

Compile a query

var qry = new Query("Table").Compile();

Project columns

var qry = new Query("Table").Project("Col1", "Col2");

Where

var qry = new Query("Table").Where("Col1", "ABC");

Where specifying the operator

var qry = new Query("Table").Where("Col1", "!=", "ABC");

Where in a list of values

var qry = new Query("Table").WhereIn("Col1", new[] { "A", "B", "C" });

Where between two date values

var qry = new Query("Table").WhereBetween("Col1", new DateTime(2022, 1, 1), new DateTime(2022, 6, 30));

Where not between two date values

var qry = new Query("Table").WhereNotBetween("Col1", new DateTime(2022, 1, 1), new DateTime(2022, 6, 30));

Order by ascending

var qry = new Query("Table").OrderBy("Col1", "Col2");

Order by descending

var qry = new Query("Table").OrderByDesc("Col1", "Col2");
