SQL中的存储过程与子字符串一起使用

Question

I have this stored procedure here:

else if(substring(@SMS,1,1)='S')
begin
insert into WEB_POROSIA..SMS_SERVISI(IDTICKET, MBYLLUR) values(convert(int,substring(@SMS,2,len(@sms)-1)),1)
select @sms
end

What it does is: I send a SMS like this:

S 23 and in the database it saves the 23 value..

Now, it works like this but not if I add a letter before: ie

S B21 it should insert B21 to the table...

How to modify it?

Answer 1

values(convert(int,substring(@SMS,2,len(@sms)-1)),1)
               ^ Because you are converting it into int

You can convert into varchar if you to get B

values(convert(varchar,substring(@SMS,2,len(@sms)-1)),1)

(Assuming you will alter the table and change the datetype from int to varchar )

Answer 2

You will need to remove the conversion to int:

insert into WEB_POROSIA..SMS_SERVISI(IDTICKET, MBYLLUR) values(substring(@SMS,2,len(@sms)-1),1)

You may also need to modify the type on the target column if that is also using int.
