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]
For the template that constructs query strings using separate template parameters, see {{Internal link with parameters}}. Quick overview This template creates an internal link to the specified page (1) with the specified query string (qs) of the form qs=name=value&name2=value2 and optionally the specified caption (2) which defaults to the ...
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.
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 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.
Giving this a value will make the template ignores subtemplates and their parameters when looking for a value in a template. Can be used for more precise grabbing of parameters as opposed to using a parameter index. Default no: Boolean: optional: Ignore blank values: ignore_blank: Ignores keys with blank values when deciding which index of a ...
Gives examples of template parameter source code Template parameters [Edit template data] Parameter Description Type Status Parameter name 1 The parameter name. Give this parameter as explicitly blank and just fill in parameter 2 when you want to show an unnamed parameter. String suggested Value name 2 The value name. When the first parameter is given but is blank, the second represents an ...
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.
