A custom value for a parameter may be supplied by using |[parameter name]=[value] in place of |[parameter name]. Any formatting for such a value – including, for instance, italics – must be supplied as part of the value (e.g. |parameter=''value''<br/>). Custom values cannot be used for parameters whose names begin with an underscore ("_").
This template can take any number of unnamed parameters as parameters accompanying the template link (or name); see Examples below. Examples Use the displayed value in the code column, not the underlying source code.
All parameters are separated with the pipe character "|". The first "parameter" is always the name of the template that you wish to use and as such is not formally a parameter at all. In this case, it is Querylink. The first formal parameter passed to the template should be the name of the internal page that you wish to link.

The code {{{xxx}}} expands to the value of the parameter named "xxx". The codes {{{1}}}, {{{2}}}, and so on are expanded to the first, second, and so on unnamed parameters. (Note that an unnamed parameter can ...
In the above example, the application might supply the values "bike" for the first parameter and "10900" for the second parameter, and then later the values "shoes" and "7400". The alternative to a prepared statement is calling SQL directly from the application source code in a way that combines code and data.
