From SQL to DAX: Filtering Data The WHERE condition of an SQL statement has two counterparts in DAX: FILTER and CALCULATETABLE. In this article we explore the differences between them, providing a few best practices in their use. As a starting point we are going to have a quick look at how simple DAX queries are structured. Having opened Analysis Services we note that there is a Tabular Analysis Services database called “SalesCommissionReport”. We shall be working with this database. We now open a ‘New Query’ (see above). By: Siddharth Mehta Overview. In this chapter we will cover the method of selecting data by evaluating DAX expressions in SSMS. The evaluate clause is the equivalent of a SELECT statement in T-SQL, which can be used to select data from tabular models. Any DAX expression that returns a table. DataType: An enumeration that includes: INTEGER, DOUBLE, STRING, BOOLEAN, CURRENCY, DATETIME: Value: A single argument using Excel syntax for a one dimensional array constant, nested to provide an array of arrays. This argument represents the set of data values that will be in the table For example, DAX originally emerged from a Power Pivot add-in for Excel, as a formula language extension for creating calculated columns and measures for data analysis (which are also integral elements of one SSAS Tabular model database, too), but when Microsoft added support for DAX queries in SQL Server 2012, BI experts started “daxing” data from DAX 30 Index - 27 Year Historical Chart. Interactive daily chart of Germany's DAX 30 stock market index back to 1990. Each data point represents the closing value for that trading day. The current price is updated on an hourly basis with today's latest value. The current price of the DAX 30 Index as of March 16, 2020 is 8,742.25. Data Analysis Expressions (DAX), originally the formula language for PowerPivot workbooks, can also be used within the MDX query window of SSMS to directly access data from a tabular SSAS database, an in-memory database that uses the xVelocity analytics engine and compression. Robert Sheldon shows how easy it is to retrieve data from a tabular database.

The Data Analysis Expressions (DAX) language is a formula language for Power Pivot, Power BI Desktop, and Tabular modeling in SQL Server Analysis Services (SSAS), which allows users to define custom calculations in PowerPivot tables (calculated columns) and in Excel PivotTables (measures).

12 May 2018 A question I get all the time is which database or… data at the source, in Power Query using M script, or in the data model using DAX?”.
With DAX queries, you can query and return data defined by a table expression. Reporting clients construct DAX queries whenever a field is placed on a report surface, or a whenever a filter or calculation is applied. DAX queries can also be created and run in SQL Server Management Studio (SSMS) and open-source tools like DAX Studio. The most important difference between DAX when used in Measures and Calculated Columns and DAX as a query language is that the query language always returns a table. The resulting table will consist of one or more columns, none or more rows, and data inside none or more of the cells in the table. The Data Analysis Expressions (DAX) language is a formula language for Power Pivot, Power BI Desktop, and Tabular modeling in SQL Server Analysis Services (SSAS), which allows users to define custom calculations in PowerPivot tables (calculated columns) and in Excel PivotTables (measures).
2 Sep 2016 Requirements for querying with DAX include SQL Server Management Studio 2014 or higher with SSAS Tabular instance, and SSAS Tabular
Data Analysis Expressions (DAX), originally the formula language for PowerPivot workbooks, can also be used within the MDX query window of SSMS to directly access data from a tabular SSAS database, an in-memory database that uses the xVelocity analytics engine and compression. Robert Sheldon shows how easy it is to retrieve data from a tabular database. The COALESCE function in DAX. COALESCE is a DAX function introduced in March 2020. This article describes the purpose of COALESCE and how to simplify DAX expressions by removing verbose conditions, and yet obtain the same result.
