SQL injection (or not?)

Hi.

I'm having weird situation with sql injection (I guess). Unfortunately there is
no error message displayed - blind injection, so all that I know - query is
valid or not.

script.aspx?parameter=' and 'a'%2b'a'='aa
no result, aparently query is invalid, so it is not MSSQL, kind of

script.aspx?parameter=' and concat('a','a')='aa
returns page, sql query turns out to be valid, MySQL??

meanwhile
script.aspx?parameter=' and concat('a','a','a')='aaa
no result, so it is not MySQL

also I know that database should be MSSQL

concat is first function I found to work. Maybe it is not sql injection? What
else could it be?
