Wierd convert problem

We are converting a char to numeric (so we can do a sort) and the values being returned are wrong. Most of the time they are fine as in the first example.

Here's the syntax:

This one is fine:

select convert(int,(convert(varbinary(10),rtrim('2003-189807')))) --returns 943274032
select convert(int,(convert(varbinary(10),rtrim('2003-190047')))) --returns 959459380


This one is wacky:

select convert(int,(convert(varbinary(20),rtrim('2003-189807')))) --returns 959983671
select convert(int,(convert(varbinary(20),rtrim('2003-190047')))) --returns 808465463

Why would the bottom one line return a value that's lower (then the first example) , when the number we are passing it is higher?

Any help or suggesions GREATLY appreciated.

Here is your answer

select convert(varbinary(20),rtrim('2003-189807')), datalength(convert(varbinary(20),rtrim('2003-189807')))
select convert(varbinary(20),rtrim('2003-190047')), datalength(convert(varbinary(20),rtrim('2003-190047')))

select convert(varbinary, 959983671), datalength(convert(varbinary, 959983671))
select convert(varbinary, 808465463), datalength(convert(varbinary, 808465463))

Bambola.
