Question: Get Data Advanced SQL Statement using existing PowerBI field

[MathewT]

Greetings!  I want to filter rows I'm bringing into Power BI Desktop using the advanced option sql query and referencing an already-created field as part of that query. 

If my large database to import/filter has a table called NewTable and I have a table already in PowerBI called SmallTable and both contain a field called CommonID, how do I write the query to Select/Import only rows from NewTable where NewTable[CommonID] is also in SmallTable[CommonID].   I can't seem to find the right syntax to enable Power BI Desktop to reference SmallTable.

Hi @MathewT ,

This is Table1:

This is Table2:

Table1 has connected to Power BI by Direct Query mode.

Please try:

SELECT Table2.* FROM Table2 INNER JOIN Table1 ON Table2.ID = Table1.ID

I think this is the result you want:

Thanks for your response. Table1 is part of the SQL database being read in. Table2 is a table ALREADY in PowerBI. The probem is PowerBI is not recognizing the Table2 reference.

Hi @MathewT ,

On my test, Table 1 is a table already in Power BI. Table 2 is part of the SQL database being read in. 

Please check again.
