I have a query that failing with this error:
"Error converting data type nvarchar to bigint"
My line that's failing is this:
INNER JOIN Country ON ColMeta.xCountry = Country.countryID
ColMeta.xCountry is nvarchar(1000)
Country.countryID = bigint
Is there a way to convert this on the fly (here in the query) without having to modify the database tables?
Thanks

I would agree with Brandon as I double checked and size doesn't impact this with NVARCHAR. I have seen it with some datatypes that it needs a numeric data type with same length, but I was able to cast NVARCHAR(1000) as long as the length of actual data strings are 19 characters or less.
If they are over that, then you have to use a different data type.
If you have string values, then find different column to match against like Brandon indicated.
Sometimes it is the simpliest ways that work best. Gallitin's solution to focus on casting the BIGINT to NVARCHAR(1000) is a good approach. Although the fact that the xcountry would not cast to BIGINT would state that it will probably not match up to your BIGINT countryid for at least one value which may be what you want anyway since you are using an INNER JOIN.
Greddin, glad Gallitin's solution worked for. To solve the root of the issue though, I would check your data for xcountry value greater than 19 characters if you can't change datatype. Spaces don't impact the cast, so it is actual data length.
SELECT xCountry
FROM ColMeta
WHERE LEN(LTrim(RTrim(xCountry))
Good luck!

Is colMeta.xcountry the NAME of the country? If so, perhaps your country table contains a NAME as well and you could join on the name instead of the country.countryID
So:
INNER JOIN Country ON ColMeta.xCountry = Country.countryNAME
