sql 去零函数 datagridview中数字类型常出现后面的零不能去掉

复制代码 代码如下:

declare @bl decimal(10,6),@num int,@num1 int ,@str char(20),@str1 char(20),@str2 char(20),@str3 char(20),@zx int,@zx1 int

set @bl=1110.10000

set @str1=ltrim(reverse(cast(@bl as char(30)))) —颠倒

print @str1

set @zx1=cast(@bl as int)

set @str2=cast(@zx1 as char(10)) –取整数部分

print @zx1

set @num=len(@str2)

print @num

set @num1=charindex(‘.’,@str1)

print @num1

set @str1=substring(@str1,0,@num1)

set @zx1=cast(@str1 as int)

print @str1

set @str3=ltrim(reverse(cast(@zx1 as char(10)))) –取小数部分

if @str3=0

set @str=rtrim(cast(@str2 as char(20)))

else

–print @str2

–print @str3

set @str=rtrim(cast(@str2 as char(20)))+’.’+rtrim(cast(@str3 as char(6)))

print @str

—set @str3=cast(@str2 as decimal(10,6))
