Hi sagidam ,
The UNION operator is used to combine the result-set of two or more SELECT statements.
- Each SELECT statement within UNION must have the same number of columns
- The columns must also have similar data types
- The columns in each SELECT statement must also be in the same order
You may list the corresponding columns like syntax codes below:
SELECT City, Country FROM Customers
WHERE Country='Germany'
UNION
SELECT City, Country FROM Suppliers
WHERE Country='Germany'
ORDER BY City;
You may also create a calculated table like DAX below to combine columns using DAX .
New table= UNION (SELECTCOLUMNS(Table1,"Account Name",Table1[A]),SELECTCOLUMNS(Table2,"Account Name",Table2[B]))
