New Post: DAX Query Generator

API Ranet UI lets you create a DAX-query layout structure in terms of the areas of the columns and filters. On the basis of this structure generates DAX-query.

AttributeColumn year = new AttributeColumn("Date", "Calendar Year");
year.FilterValues.Add("2006");

AttributeColumn date = new AttributeColumn("Date", "Date", true);
date.FilterValues.Add("DATE(2006,1,1)");
date.FilterValues.Add("DATE(2006,1,2)");

AttributeColumn countryRegion = new AttributeColumn("Geography", "Country Region Name", true);

AttributeColumn product = new AttributeColumn("Product", "Product Category Name", true);
product.FilterValues.Add("\"Bikes\"");
product.FilterValues.Add("\"Clothing\"");

MeasureColumn totalSales = new MeasureColumn("Sales Territory", "Total Sales");

QueryStructure queryStructure = new QueryStructure();
queryStructure.Columns.Add(year);
queryStructure.Columns.Add(date);
queryStructure.Columns.Add(countryRegion);
queryStructure.Columns.Add(product);
queryStructure.Columns.Add(totalSales);

Operator exp1 = new Operator(new Column(year), "=", new DaxFragment("2007"));
Operator exp2 = new Operator(new Column(countryRegion), "=", new DaxFragment("\"United States\""));
Operator exp3 = new Operator(exp1, "&&", exp2);
Parentheses exp4 = new Parentheses(exp3);
Operator exp5 = new Operator(new Column(year), "=", new DaxFragment("2008"));
Operator exp6 = new Operator(new Column(countryRegion), "=", new DaxFragment("\"United Kingdom\""));
Operator exp7 = new Operator(exp5, "&&", exp6);
Parentheses exp8 = new Parentheses(exp7);
Operator exp9 = new Operator(exp4, "||", exp8);
Operator exp10 = new Operator(new Column(new MeasureColumn("Internet Sales", "Internet Total Sales")), ">", new DaxFragment("200000"));
Operator exp11 = new Operator(exp9, "||", exp10);
queryStructure.Filters = exp11;

string daxQuery = DaxGenerator.Generate(queryStructure);

According to this source code will be generated following DAX query:

A full-featured visual designer DAX-query will be implemented in the short version Ranet UI.
