{{documentation subpage}}
This is a more general version of {{tl|Getalias}}, which can extract any parameter value from a [[:Category:Country data templates|country data template]] instead of just parameters named "... alias" or "... alias-...".

==တူဝ်ယၢင်ႇ==
*<code>{{tnull|getalias2|United Kingdom|flag alias}}</code> &rarr; <code>{{getalias2|United Kingdom|flag alias}}</code> (the value of {{para|flag alias}} in {{tl|Country data United Kingdom}})
*<code>{{tnull|getalias2|Georgia (U.S. state)|shortname alias}}</code> &rarr; <code>{{getalias2|Georgia (U.S. state)|shortname alias}}</code> (the value of {{para|shortname alias}} in {{tl|Country data Georgia (U.S. state)}})
*<code>{{tnull|getalias2|Nepal|border}}</code> &rarr; <code>{{getalias2|Nepal|border}}</code> (nothing, since {{para|border}} is set to nothing in {{tl|Country data Nepal}})
*<code>{{tnull|getalias2|Russia|border}}</code> &rarr; <code>{{getalias2|Russia|border}}</code> (no {{para|border}} parameter is defined in {{tl|Country data Russia}})
*<code>{{tnull|getalias2|Nepal|size}}</code> &rarr; <code>{{getalias2|Nepal|size}}</code> (in {{tl|Country data Nepal}}, the {{param|size}} parameter is passed through with fallback value 23x20px)
*<code>{{tnull|getalias2|Russia|size}}</code> &rarr; <code>{{getalias2|Russia|size}}</code> (in {{tl|Country data Russia}}, the {{param|size}} parameter is passed through with empty fallback value)

==Usage with variant==
The {{para|variant}} parameter can be used to extract a variant parameter value, and returns the main parameter value if the variant parameter is undefined:
*<code>{{tnull|getalias2|United Kingdom|flag alias|variant{{=}}civil}}</code> &rarr; <code>{{getalias2|United Kingdom|flag alias|variant=civil}}</code> (the value of {{para|flag alias-civil}})
*<code>{{tnull|getalias2|United Kingdom|flag alias|variant{{=}}foo}}</code> &rarr; <code>{{getalias2|United Kingdom|flag alias|variant=foo}}</code> (non-existent variant; returns the value of {{para|flag alias}} as fallback)
