This post shows how to delete SSAS Tabular partitions with C#. This is an improvement over a PowerShell script I previously wrote about, Delete SSAS Partitions with TMSL and PowerShell, because it is more dynamic and doesn’t require a manually-authored TMSL script. Specifically, the code below deletes all partitions that contain a specified suffix, which is useful for quickly deleting all partitions used for development purposes. I’ve worked with SSAS models that required several development partitions in order to prevent the workspace database from growing too large. Deleting them manually after a deployment to a server would be tedious, and it would be easy to forgetRead More →

Push Performance Counter Data into a Power BI Streaming Dataset

In the previous post I showed how you can Push Data into Power BI Streaming Datasets with C#. That example used dummy data. In this post I’ll show how to push performance counter data into a Power BI Streaming Dataset as a real world example. This scenario allows for monitoring a computer or application in near real time in the browser. I won’t go through the steps of creating a Power BI Streaming Dataset. You can reference my previous post if you need instructions. I will note that the value names that you choose in the Streaming Dataset must match the C# property names for theRead More →

This post shows how you can generate optimized multi-value DAX parameters in SSRS and achieve greater performance compared to the DAX PathContains function. This will be a short post that provides the SSRS expression to convert multiple SSRS parameters into a double-pipe delimited string for use in a DAX query. In other words, the goal is to use the DAX OR operator (||) instead of the PathContains function. I’m assuming the reader has experience with SSRS, so not all steps will be shown. Imagine that you have multi-value parameter that allows users to select multiple month – year values such as Sep 2017, Oct 2017, etc. TheRead More →

The previous post looked at how to process SSAS Tabular models with TMSL. Since SQL Server adds new JSON capabilities in 2016, let’s look at how to convert TMSL JSON to a Table with OPENJSON. OPENJSON is a new function in SQL Server 2016 that, per Microsoft: OPENJSON is a table-valued function that parses JSON text and returns objects and properties from the JSON input as rows and columns. In short, OPENJSON converts JSON text to a table. Since TMSL is JSON, this function can convert a SSAS Tabular processing script into a table. This could be useful if you wanted to document a SSASRead More →

Process SSAS Tabular Tables and Partitions with TMSL

This post shows how to process SSAS Tabular tables and partitions with TMSL. TMSL stands for Tabular Model Scripting Language, and it is used for working with SSAS Tabular databases programmatically starting with compatibility level 1200 (SQL Server 2016). Multidimensional models and previous versions of SQL Server all use Analysis Services Scripting Language (ASSL for XMLA). A common use for TMSL is automating the processing of tabular models using the SQL Agent, SSIS, PowerShell, or some other application. One typical processing sequence is a series of Process Data commands followed by a Process Recalc at the end. Here’s what the TMSL code looks like in this scenario:

This post demonstrates how to delete SSAS partitions with TMSL and PowerShell. TMSL stands for Tabular Model Scripting Language, and it is used for working with SSAS Tabular databases programmatically at compatibility level 1200 (SQL Server 2016). Multidimensional models and previous versions of SQL Server all use Analysis Services Scripting Language (ASSL for XMLA). A common use for TMSL is automating the processing of tabular models using the SQL Agent, SSIS, PowerShell, or some other application. Another use could be deleting partitions used for development after deploying a model. That process goes like this: A partition is created for development purposes that contains a subset of theRead More →
