It only indicates, that sql query has failed. It is sql injection, when you are able to INJECT something to that query.

Let's assume, that "id=55" is valid page.
Run test's below :

Code:

http://site.com/?page=viewcolumn&id=55


Code:

http://site.com/?page=viewcolumn&id=55--+


Code:

http://site.com/?page=viewcolumn&id=55'--+


Code:

http://site.com/?page=viewcolumn&id=55)--+


Code:

http://site.com/?page=viewcolumn&id=55')--+


Code:

http://site.com/?page=viewcolumn&id=53%2b2


Error messages? Normal page? This tests will give you an anwer you are searching for.

Then there is no sql injection, just missing parameter check (lazy programmer) ...
