Joe Billingham shows off two similar-sounding functions:
I had an issue recently where a third-party application had been updated and both the new and legacy versions were being used side-by-side. Logging data from both versions was being written to two separate Azure SQL databases.
The customer needed a Power BI report showing both old and new logging data sets as a single source. If both databases were SQL Server databases, I could have written a view with a cross-database join, imported that into Power BI and thought no more about it. However, the two sources being Azure SQL Databases, with no easy way to join the tables, caused an issue.
This is where the Merge and Append functions in Power Query come in.
Read on for the solution.
