Hi,

I am presently transferring a query from Access into SQL Server. A field in the Access query contains the function Val() which takes the first value it sees within a string until it reaches a non-numeric value. I was wondering, is there such a function in SQL Server?

Thanks

There is no built-in function for this, but not too difficult to build.

-- prepare sample data
declare @t table
(
	a varchar(100)
)

insert @t 
select '173hs' union all 
select '58d' union all 
select 'aa' union all 
select '863'

-- actual query
select 
	left(a, patindex('%[^0-9]%', a)-1) as a
from @t
where 
	patindex('%[^0-9]%', a) > 1
union all
select 
	a
from @t
where 
	patindex('%[^0-9]%', a) = 0
