![]() Then when using date, it should be showed correctly. Outside of SQLBI, most of Alberto's personal time is spent practicing video games, in the vain hope of eventually beating his son.You can set the system date with this command: sudo date -set=" 10:05:59.990" Thus, you can easily meet Alberto by looking up local Power BI user groups during scheduled courses. When traveling for work, he likes to engage with local user groups to provide evening sessions about his favorite topics. He loves to be on stage both at large events and at smaller user groups meetings, exchanging ideas with other SQL and BI fans. Alberto offers consulting services on large and complex data warehouses to provide assessments and validation of project analysis or to perform specific problem-solving activities.Īlberto is a well-known speaker at many international conferences, like PASS Summit, Sqlbits, and Microsoft Ignite. Today, Alberto's main activities are in the delivery of DAX and data modeling workshops for Power BI and Analysis Services all around the world. He is a Microsoft MVP and he earned the SSAS Maestro title, the highest level of certification on Microsoft Analysis Services technology. He and Marco Russo created, where they publish extensive content about Business Intelligence.Īlberto published several books about Analysis Services, Power BI, and Power Pivot. Understanding context transition in DAXĪlberto started working with SQL Server in 2000 and immediately his interest focused on Business Intelligence.Automatic time intelligence in Power BI.Strings are compared according to alphabetical order. Returns the largest value in a column, or the larger value between two scalar expressions. Returns the smallest value in a column, or the smaller value between two scalar expressions. Returns a table with one column of dates calculated from the model automatically. Returns a table with one column of all dates between StartDate and EndDate. "Quarter", "Q" & TRUNC ( ( MONTH ( ) - 1 ) / 3 ) + 1Ī more complete example of a date table is available in the article Reference Date Table in DAX and Power BI. VAR MaxYear = YEAR ( MAX ( Sales ) )ĪND ( YEAR ( ) >= MinYear, YEAR ( ) = MinYear, YEAR ( ) <= MaxYear ) For example, the following expression is a good starting point for a date table: Therefore, the easiest way of creating a simple calendar table is to rely on CALENDARAUTO to find all dates available, and then remove from all the dates found the ones that don’t fall inside the period of interest. sales) and then moves them respectively to the first and last day of these given years. On the other hand, CALENDAR requires the computing of the MIN and MAX date of all transactions available (e.g. As a result, CALENDARAUTO might create a date table containing many irrelevant years. In fact, CALENDARAUTO searches in all the date columns of the data model, including – for example – customer birth dates. Unfortunately, none of these two functions is perfect. CALENDAR requires the boundaries of the set of dates, whereas CALENDARAUTO searches among all the dates in the data model and automatically finds the first and last year referenced within the model. Both functions return a table with a single column named “Date” and a list of values for the dates. There are a couple of functions in DAX that create a simple date table: CALENDAR and CALENDARAUTO. ![]()
