Parameter names example}} – or, alternatively, {{Generic template demo}} – is intended to assist template documentation by producing a generic instance of the template that uses parameters' names as those parameters' values.
To override this behaviour you can specify the |_template= parameter explicitly. The formatting of the parameter names can be changed with the |_display= parameter. By default, the parameter names are shown in triple braces (the parameter standard, e.g. {{{name}}} ), but if |_display=italics or |_display=italic is set, they are shown in italics.
} extracts a specified template's parameters and performs a variety of tasks to aid in its documentation or WP:TFD merge nominations. It itself takes two parameters: |1=, the output format; and |base=, the title of a template. The compare function requires a third parameter, |other=. {} must always be substituted. Its usage is demonstrated below.
Certain templates have the parameter "on" by default; see the main table for all alternate options. If a row renders identically to a previous row, it means the current template does not support that option and {{ tlg }} needs to be used instead.
The Template Parameters tool is available for viewing template parameter usage in articles. It works with TemplateData to show the frequency of parameter name usage in a template's mainspace transclusions, along with whether or not each parameter is listed in that template's TemplateData code as a supported parameter. For a required parameter ...
This template uses Module:Check for unknown parameters. All allowed parameters must be listed at {{#invoke:Check for unknown parameters|...}} in the template's own code. A call with an unlisted parameter may cause a warning in previews and may add a tracking category. There are two optional parameters preview and category.
PreparedStatement allows the dynamic query to vary depending on the query parameter. [11] CallableStatement – CallableStatement is a subinterface of the Statement interface. [11] It is used for executing stored procedures on the database. [11] [12] Both input and output parameters must be passed into the database for stored procedures. [13]
A parameter is a particular piece of information that can be specified in a template call to affect the expansion of the template. A parameter has a value. A named parameter has a name; an unnamed parameter has a position. A template call specifies a parameter and the code that does that is a parameter specification.
