was reading through someones
code and i don't really understand the sql which is being constructed below :
insert into ...... values(?, ?, ?, %s, ?, %s, ?, ?, ? ....)
i know what the ? is for but what does the '%s' do ??
thanks in advance.

Perhaps the code you mention was used in a Formatter.
For instance I could write somewhat like this:
int salary = 100; String sql = "SELECT * FROM employee WHERE id = ? and salary >= %s"; String formattedSql = String.format(sql, salary); //would replace %s with the actual salary PreparedStatement stm = conn.prepareStatement(formattedSql) ...
Do you know if this is the case?
I agree. Here's the link:
