How do I add static data to an excel sql-query? - sql

Question

I have a running query in Excel which gets data from an sql-server. I need to add static data in order to correct old data. I have tried with Union but Excel returns "Incorrect syntax near '.'."
My thought was to use Union:
SELECT column1, column2 FROM table1
UNION
SELECT "Trying" as column1, "Testing" as coulmn2 FROM table1;
But the data "Trying" and "Testing" are not really coming from table1 since I add it myself. Maybe this can't be done?
SELECT ft.ArtNr, ft.FaktRadSumma, ft.ordtyp, ft.ForetagKod, ft.FtgNr,
ft.Period, ft.Redovisnar, fr.FtgNamn, ft.KundKategoriKod, kus.kundklass,
ft.Date, ft.FaktTB, ft.FaktTG, ar.ArtKod, ar.artprodkonto, xm.arttypbeskr,
x1kk.kundklassbeskr, ft.faktradkost
FROM IRISJEV01.dbo.ft ft
UNION
SELECT '51143' as ft.ArtNr, 0.001 as ft.FaktRadSumma, 1 as ft.ordtyp, 10 as
ft.ForetagKod, '100622-02' as ft.FtgNr, 11 as ft.Period, 2018 as
ft.Redovisnar, 'Stockholm' as fr.FtgNamn, 0 as ft.KundKategoriKod, 'SC' as
kus.kundklass, '2018-11-07 00:00:00' as ft.Date, 2,24E+06 as ft.FaktTB,
2,23 as ft.FaktTG, 22 as ar.ArtKod, STD as ar.artprodkonto, 'Klockor &
timers' as xm.arttypbeskr, 'Syncentral' as x1kk.kundklassbeskr, -2238058 as
ft.faktradkost
FROM IRISJEV01.dbo.ft ft
I expect to get all lines from the part above Union and the one line from below Union with the data specified, e.g. 51143, 0.001, etc...
