If I remove all the ‘ characters from a SQL query, is there some other way to do a SQL injection attack on the database?
How can it be done? Can anyone give me examples?

Yes, there is. An excerpt from Wikipedia
'SELECT * FROM data WHERE id = ' + a_variable + ';'It is clear from this statement that the author intended a_variable to be a number correlating to the ‘id’ field. However, if it is in fact a string then the end user may manipulate the statement as they choose, thereby bypassing the need for escape characters. For example, setting a_variable to
1;DROP TABLE userswill drop (delete) the ‘users’ table from the database, since the SQL would be rendered as follows:
SELECT * FROM DATA WHERE id=1;DROP TABLE users;SQL injection is not a simple attack to fight. I would do very careful research if I were you.
