MDX Query change column title - ssas

Question

These are my first mdx queries. I would like to execute some queries from a C# application and convert the results to a JSON file or a tabular format.
So I need the columns titles, you can see in the picture in attachment the columns title is empty, how can I change them in the mdx query ?
SELECT { [Measures].[Nombre Inscrits] } ON COLUMNS,
{ ([ZONE CLIENT].[ID ZONE].[ID ZONE].ALLMEMBERS * [DimDate].[Year].[Year].ALLMEMBERS)}
ON ROWS FROM [Loisirs cube]

Answer 1

The empty cells are empty because in the result space if a name is given to them, it will not make sense, I would suggest you handle it in your code. However for the sake of learning you can use the below query , and ignore the first two columns of the result
with member
[measures].[ID ZONE] as
[ID ZONE].[ID ZONE].currentmember.name
[measures].[Year] as
[DimDate].[Year].currentmember.name
SELECT
{[measures].[ID ZONE],[measures].[Year], [Measures].[Nombre Inscrits] } ON COLUMNS,
{ ([ZONE CLIENT].[ID ZONE].[ID ZONE].ALLMEMBERS * [DimDate].[Year].[Year].ALLMEMBERS)}
ON ROWS FROM [Loisirs cube]
So here a sample on adventure works
SELECT
{ [Measures].[Internet Sales Amount] } ON COLUMNS,
{ ([Product].[Category].[Category].ALLMEMBERS * [Date].[Calendar Year].[Calendar Year].ALLMEMBERS)}
ON ROWS
FROM [Adventure Works]
Result
Now lets modify the query
with member
[Measures].[Category]
as
[Product].[Category].currentmember.name
member [Measures].[Year]
as
[Date].[Calendar Year].currentmember.name
SELECT
{ [Measures].[Category], [Measures].[Year],[Measures].[Internet Sales Amount] } ON COLUMNS,
{ ([Product].[Category].[Category].ALLMEMBERS * [Date].[Calendar Year].[Calendar Year].ALLMEMBERS)}
ON ROWS
FROM [Adventure Works]
Result
