IsNumeric returns false inexplicably

[Glenn Venzke]

For some reason all of a sudden number values pulled from a SQL server field
with a datatype of "numeric" are not being recognized by asp classic as valid
number values. They were previously, but now are not. When I use the
"IsNumeric" function, it returns false. When I try to Ctype it to an integer,
I get an "overflow" error. If I change the datatype of the database field to
"int", it works fine. Whats the deal? The values I'm working with currently
range from 33800 to 33850.

CInt in VBScript only goes to 32k. So, use CLng instead.

IsNumeric isn't exactly the most accurate test, either, but in order to see
what is going on, please provide a repro.

"numeric" is not a sufficient description of the column's datatype. Please
tell us the precision and scale of the column.

So what changed? And please provide some context. Are you talking about
recordset fields? If so, what does the Type property of the field contain?
Or are you talking about stored procedure output parameters?

I don't know of a Ctype function. Please be specific.

That's why I asked you to be specific. CInt would generate an overflow error
with these values. CLng would not.
