Here, the <code>one_to_many</code> is a list of players on the team in question. For each ONE team, there are MANY players, so the field <code>IDs</code> that's sent to the template is a comma-separated list of players, grouped by team page.

==Parameters & Invocation==
You can also run compound queries using <code>compound</code>. It has the same syntax as <code>#cargo_compound_query</code> but with a few exceptions:

|q?tables= <!-- corresponds to table / tables -->
* Each query must be numbered as in <code>|1=(query1)|2=(query2)|3=...</code>, etc.
|q?join= <!-- corresponds to join on -->
* Because of how compound query uses <code>;</code> as a separator, strings with this character cannot be used. This can be worked around by specifying <code>metaseparator</code> to be another symbol, and splitting each query's arguments using that delimiter instead.

This module is taken from Leaguepedia's CargoQuery module.

This module lets you get around the |no html bug that Cargo has by avoiding |format=template. This module implicitly assumed you ARE using named args in your template (corresponding to |named_args=yes; you do not need to specify this.)

Unlike |format=template, this wrapper will NOT rename parameters with underscores in them to use spaces instead.

Parameters

  • You may specify all parameters the same as if they were parameters in #cargo_query.

One-To-Many

This template allows for one-to-many support, allowing you to specify a field to treat equivalently to a List of ... field. Syntax is as follows:

  • |one_to_many=, a list of fields you want concatenated together.
  • |one_to_many_group=, the thing you want our one-to-many values grouped by. UNLIKE the |group by= parameter, this should be the FINAL name of a field, so something on the RIGHT SIDE of the equals sign in your |fields= parameter.
  • |one_to_many_sep=, defaults to comma. Currently you must pick the same separator for all of your one-to-many fields.

Example

{{#invoke:CargoQuery|main
 |table=Teams,ListplayerCurrent=LPC
 |join on=Teams._pageName=LPC._pageName
 |where=Teams.Region="North America" AND LPC._pageName IS NOT NULL
 |fields=Teams._pageName=Page
 |one_to_many=LPC.ID=IDs
 |one_to_many_group=Page
 |one_to_many_sep=,
 |template=<template>
 |intro={{(!}} class="wikitable"
 |outro={{!)}}
 |limit=10
}}

Here, the one_to_many is a list of players on the team in question. For each ONE team, there are MANY players, so the field IDs that's sent to the template is a comma-separated list of players, grouped by team page.

Compound Queries

You can also run compound queries using compound. It has the same syntax as #cargo_compound_query but with a few exceptions:

  • default for each individual query is disabled; default must be specified outside as an additional argument, which is then applied if no queries return results.
  • Each query must be numbered as in |1=(query1)|2=(query2)|3=..., etc.
  • Because of how compound query uses ; as a separator, strings with this character cannot be used. This can be worked around by specifying metaseparator to be another symbol, and splitting each query's arguments using that delimiter instead.

Example

{{#invoke:CargoQuery|compound
|1=table=Food=F
;fields=F._pageName=Page
;where=F.CookEffect HOLDS 'heat and fire-based' AND F._pageNamespace = '0'
|2=table=Liquids=L
;fields=L._pageName=Page
;where=L.CookEffect HOLDS 'simple heat and fire-based' AND L._pageNamespace = '0'
|default=No Results!
|template=favilink page
|delimiter = <br>
|metaseparator = ;
}}
