Change titles of columns in MDX with T-SQL - tsql

Question

I created simply query with T-SQL processed OLAP cube like below:
SELECT * FROM OPENQUERY([linkedserver], 'SELECT NON EMPTY { [Measures].[Revenue] } ON COLUMNS,
NON EMPTY { ([Basic].[Name].[Name].ALLMEMBERS ) } ON ROWS
FROM [SummaryCube]');
The result of query is the table. Titles of columns in this table are defaults, ex.:"[Basic].[Names].[Names].[MEMBER_CAPTION]" but I would like to change these titles for ex.: "Names". I cannot change using aliases or I'm using aliases wrong way. Can anyone tell me how can I change name of column?

Answer 1

Instead of your SELECT *, double quote the names of the returned columns:
SELECT "[Basic].[Name].[Name].[MEMBER_CAPTION]" as Names
You need to use double quotes as SQL Server recognises square brackets as identifiers.

Answer 2

I usually do some conversions as well:
SELECT
Names = CONVERT(VARCHAR(100), "[Basic].[Name].[Name].[MEMBER_CAPTION]"),
Revenue = CONVERT(NUMERIC(18,2),CAST("[Measures].[Revenue]" AS FLOAT))
FROM
OPENQUERY
(
[linkedserver],
'SELECT
NON EMPTY { [Measures].[Revenue] } ON COLUMNS,
NON EMPTY { ([Basic].[Name].[Name].ALLMEMBERS ) } ON ROWS
FROM [SummaryCube]'
);
And if you switched to the better olapextensions addin it would be:
DECLARE #Server NVARCHAR(30) = 'SummaryCubeServerName';
DECLARE #Database NVARCHAR(50) = 'SummaryCubeDatabaseName';
DECLARE #MDX NVARCHAR(MAX) = '
SELECT
NON EMPTY { [Measures].[Revenue] } ON COLUMNS,
NON EMPTY { ([Basic].[Name].[Name].ALLMEMBERS ) } ON ROWS
FROM [SummaryCube];
'
CREATE TABLE #Results(
Names VARCHAR(250),
Revenue FLOAT
);
INSERT INTO #Results
EXEC ExecuteOLAP #Server, #Database, #MDX;
SELECT
Names,
Revenue = ISNULL(CONVERT(DECIMAL(28,8),Revenue),0.0),
FROM #Results;
