Once again we learn that you should never rely on default datatype precision, but specify it yourself!

Thanks for the interesting question. Though I hope questions like this wouldn't be necessary, and that people would always specify a length on variables to keep themselves out of trouble.

good one, thanks Rahul...:-)


declare @myvariable as varchar, @len1 varchar, @len2 varchar
set @myvariable = 'hi hello how are you'
set @len1 = (select datalength(cast(@myvariable as char)))
print @len1
set @len1 = (select datalength(cast(@myvariable as varchar)))
print @len1
set @len2 = (select datalength(convert(char, @myvariable)))
print @len2
set @len2 = (select datalength(convert(varchar, @myvariable)))
print @len2



The above code generates output as

*
1
*
1


difference of char, varchar datatypes...:-)
