[marbi]

I want to combine two tables with different number of columns.

Both tables has same common fields as A & B and would like to combine that will result to a table having fields: A, B, C, D, E, F, G, H, I, J. Kindly help.

	TABLE 1			TABLE 2
	COLUMN			COLUMN
KEY FIELD	A		KEY FIELD	A
KEY FIELD	B		KEY FIELD	B
COLUMN	C		COLUMN	G
COLUMN	D		COLUMN	H
COLUMN	E		COLUMN	I
COLUMN	F		COLUMN	J

Hi @marbi  Create a UNION SQL query combining the tables, ensuring missing columns are filled with NULL and matching fields like A and B align. Use Advanced Query Editor in Power BI to input the query in DirectQuery mode. Verify data types of common fields (A and B) match in both tables for proper merging.

Hi @marbi 
Can you please try similar SQL Code for your solution in Direct Query mode
Write this SQL in SQL Query box

SELECT
    T1.KEY FIELDA,
    T1.KEY FIELDB,
    T1.COLUMN C,
    T1.COLUMN D,
    T1.COLUMN E,
    T1.COLUMN F,
    T2.COLUMN G,
    T2.COLUMN H,
    T2.COLUMN I,
    T2.COLUMN J
FROM
    TABLE1 T1
FULL OUTER JOIN
    TABLE2 T2 ON T1.KEY FIELDA = T2.KEY FIELDA AND T1.KEY FIELDB = T2.KEY FIELDB;
