Question

I have this query

select top 10 * from FREETEXTTABLE([Venue], FullAddress,  'Canada')

which works fine, and produces results;

now if I’m calling this from code, and provide parameters, it is changed to

exec sp_executesql N'select top 10 * from FREETEXTTABLE([Venue], FullAddress,  ''@p'')',N'@p nvarchar(4000)',@p='Canada'

which produces no results whatsoever.
As far as I understand those 2 queries should produce identical output ? Or FREETEXTTABLE is especially picky about parameters ?

Answer 1

In this case, you shouldn’t add the single quotes when using a NVARCHAR parameter. Try the following instead:

EXEC sp_executesql  N'select top 10 * from FREETEXTTABLE([Venue], FullAddress,  @p)',
                    N'@p nvarchar(4000)',
                    @p='Canada'
