ASCII码是计算机上最常用的符号编码,它的H30代表十六进制数30,是字符“0”的编码。十六进制加法的结果也是十六进制数h130
(select null)) n from master.dbo.spt_values ) d cross apply(values(Substring(@v, d.n, 1)))x(v) where Ascii(v)<32 and Ascii(v) not in (9,10,13) 然后你可以这样测试它: select * from dbo.FindBadAscii ('a' + Char(10) + 'b' + Char(20) + 'c') 这将标识任何非制表符/...
