I am trying to solve a problem with a pivot query that is very similar to the one illustrated below. The first set of code works and the second does not. The only difference is in the values being pivoted on. It seems that the pivot values cannot be a number which I do not understand since the number is being treated as a string. Has anyone experienced this before?

declare @SalesQuarter table
(
SalesYear int,
SalesQuarter char(2),
SalesAmount float
)

insert into @SalesQuarter values(2006, 'Q1', 70)
insert into @SalesQuarter values(2006, 'Q2', 150)
insert into @SalesQuarter values(2006, 'Q3', 20)
insert into @SalesQuarter values(2006, 'Q4', 20)

select * from @SalesQuarter
pivot
(
sum(SalesAmount)
for SalesQuarter
in (Q1, Q2, Q3, Q4)
) as Q

----------------------------------------------------------------------------------------

declare @SalesQuarter table
(
SalesYear int,
SalesQuarter char(2),
SalesAmount float
)

insert into @SalesQuarter values(2006, '1', 70)
insert into @SalesQuarter values(2006, '2', 150)
insert into @SalesQuarter values(2006, '3', 20)
insert into @SalesQuarter values(2006, '4', 20)

select * from @SalesQuarter
pivot
(
sum(SalesAmount)
for SalesQuarter
in (1, 2, 3, 4)
) as Q

The values are used as column names so put them in brackets [] and it will work fine

declare @SalesQuarter table
(
SalesYear int,
SalesQuarter char(2),
SalesAmount float
)

insert into @SalesQuarter values(2006, '1', 70)
insert into @SalesQuarter values(2006, '2', 150)
insert into @SalesQuarter values(2006, '3', 20)
insert into @SalesQuarter values(2006, '4', 20)

select * from @SalesQuarter
pivot 
(
sum(SalesAmount)
for SalesQuarter
in ([1], [2], [3], [4])
) as Q

Thanks. That’s what I was looking for.
