>>>Hi!

>>>The variable past "?" is called "parameter" for SQL command(s). When executing, all "?{variable}" are automatically replaced by real values and sent to SQL server. More, these values are replaced in a such way that you can pass really large data (megabytes) using this approach, that is limited when passing data directly as a constant. This way is very useful for saving General and large Memo field data.
