The concatenation operator is the plus sign (+). You can combine, or concatenate, two or more character strings into a single character string. You can also concatenate binary strings.
The following code is an example of concatenation operator that combines the product name with the product's unique name:
WITH MEMBER Measures.ProductName AS Product.Product.CurrentMember.Name + " (" + Product.Product.CurrentMember.UniqueName + ")" SELECT Measures.AllMembers ON COLUMNS, Product.Product.Members ON ROWS FROM [Adventure Works]
When the strings used in a concatenation both have the same collation, the resulting concatenated string has the same collation as the inputs. When the strings used in a concatenation have different collations, the rules of collation precedence determine the collation of the resulting concatenated string.
