SqlPlus SP2-0734: Error

Question

I am new to using SqlPlus but not new to using SQL, and I get the following error after writing this in my editor and attempting to run the script that I wrote. All of this appears to be valid and works on sql fiddle... I am not sure what the issue is. Any ideas?? None of the files I create seem to work....

SQL> start sales.sq;

which contains

1  create table salesreps
2  (empl_num number(3,0) primary key,
3  name varchar2(15) not null,
4  age number(3,0),
5  rep_office number(2,0),
6  title varchar2(10),
7  hire_date varchar2(10) not null,
8  manager number(3,0),
9  quota number(10,2),
10 sales number(10,2) not null);

Answer 1

By default SQL*Plus doesn't like blank lines. However we can easily configure our SQL*Plus environment to ignore them:

SQL>  set sqlblanklines on

We can also put the setting in our glogin.sql file (assuming we're allowed to edit it, which isn't always the case).

Note that this parameter doesn't work in ancient versions of the client.

Answer 2

As mentioned in the comments, this issue can be caused by having the UTF-8 BOM (Byte Order Mark) encoding. It can easily be fixed by copying the contents of the file to Notepad++.

In our case, the encoding changed from UTF-8 to UTF-8 BOM while editing a sql file in Azure DevOps.

Explanation: Some editors, will automatically add those bytes when you save a file in UTF-8 format. Some of them give you the option not to save those bytes, which is usually the best option. To get rid of those bytes, try an editor like Notepad++, which gives you the option not to save those characters.
