How to generate an excel file (.xlsx) from SQL Server - file

Question

I have this query:
WITH InfoNeg AS
(
SELECT DISTINCT
n.idcliente,
CASE
WHEN DATEDIFF(MONTH, MAX(n.fechanegociacion), GETDATE()) <= 2
THEN 'Negociado 6 meses'
ELSE NULL
END AS TipoNeg
FROM
SAB2NewExports.dbo.negociaciones AS n
WHERE
Aprobacion = 'Si'
AND cerrado = 'Si'
GROUP BY
n.idcliente
), Multi AS
(
SELECT DISTINCT
idcliente, COUNT(distinct idportafolio) AS NumPorts
FROM
orangerefi.wfm.wf_master_HIST
WHERE
YEAR(Fecha_BKP) = 2021
AND MONTH(Fecha_BKP) = 08
GROUP BY
idcliente
)
SELECT DISTINCT
m.IdCliente, c.Nombre1
FROM
orangerefi.wfm.wf_master_HIST as m
LEFT JOIN
InfoNeg ON m.idcliente = InfoNeg.idcliente
LEFT JOIN
Multi ON m.IdCliente = Multi.idcliente
LEFT JOIN
SAB2NewExports.dbo.Clientes AS c ON m.IdCliente = c.IdCliente
WHERE
CanalTrabajo = 'Callcenter - Outbound' -- Cambiar aca
AND YEAR (Fecha_BKP) = 2021
AND MONTH(Fecha_BKP) = 08
AND GrupoTrabajo IN ('Alto') -- Cambiar aca
AND Bucket IN (1, 2) -- Cambiar aca
AND Multi.NumPorts > 1
AND Infoneg.TipoNeg IS NULL
When I run it, I get 30 thousand rows and the columns that I get when performing the query are: ClientID, name. I would like it to be saved in an Excel file when I run it, I don't know if it's possible.
Another question, is it possible to create a variable that stores text?
I used CONCAT(), but the text being so long is a bit cumbersome, I don't know if there is any alternative.
If you can help me, I appreciate it.

Answer 1

To declare a variable
DECLARE #string VARCHAR(MAX)
SET #string = concat()
then insert whatever you are concatenating

Export SQL query data to Excel
I don't know if this is what you're looking for, but you can export the results to Excel like this:
In the results pane, click the top-left cell to highlight all the records, and then right-click the top-left cell and click "Save Results As". One of the export options is CSV.
You might give this a shot too:
INSERT INTO OPENROWSET
('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=c:\Test.xls;','SELECT productid, price FROM dbo.product')
Lastly, you can look into using SSIS (replaced DTS) for data exports. Here is a link to a tutorial:

== Update #1 ==
To save the result as CSV file with column headers, one can follow the steps shown below:
Go to Tools->Options
Query Results->SQL Server->Results to Grid
Check “Include column headers when copying or saving results”
Click OK.
Note that the new settings won’t affect any existing Query tabs — you’ll need to open new ones and/or restart SSMS.
