I’ve been interviewed by Greg Low in SQL Down Under show 58, and this is *not* an April fool! We talked for one hour about Tabular, Multidimensional, Data Warehouse and just a little bit about music (you can discover which music genre I’m used to listen…).

I recently published a set of rules for DAX code formatting. The following is an example of what I obtain: CALCULATE (     SUMX (         Orders,         Orders[Amount]     ),     FILTER ( ...

If you started using DAX as a query language, you might have encountered some performance issues by using SUMMARIZE. The problem is related to the calculation you put in the SUMMARIZE, by adding what are called extension columns, which compute their value within a filter context defined by the rows considered in the group that the SUMMARIZE uses ...

Are you waiting for a usable and interactive DAX editor? Are you tired of using the MDX editor provided by SSMS as a temporary solution to write and execute a DAX query? The wait is over!
