Convert SSAS Tabular Processing Scripts Into Tables

Chris Koester shows how to take an Analysis Services Tabular processing script in TMSL format and turn it into a table using OPENJSON:

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 SSAS processing schedule.

That’s an interesting use of OPENJSON.
