This function allows, from a formula, to obtain the maximum value of a field of the documents of any Docuo category. It is not necessary that the category indicated is related to the one that contains the formula.<\/p>\n

The categoryMax function is only available in Docuo Enterprise.<\/strong><\/p>\n

For example, if we have a category of countries (PAI – Country) and we want to obtain the maximum number of inhabitants, we must use this function:<\/p>\n

Document.categoryMax(Category, Field,[Condici\u00f3n] )
\n<\/tt><\/div>\n

Where:<\/p>\n

Category<\/strong> : is the code, the name or the code – name of the category from which we want to extract the data:<\/p>\n

'PAI'<\/tt><\/div>\n

Field<\/strong> : is the text string between quotes with the label of the field from which we want to extract the maximum value:<\/p>\n

'< @PAI:Data:Population> '<\/tt><\/div>\n

Condition<\/strong> : This is an optional parameter with a T-SQL condition text string of the same type used in dropdown lists. It allows us to filter the results of the aggregate. For example, to filter Countries<\/em> in Europe:<\/p>\n

\"<<\/tt> @PAI:Data:Continent><\/tt> = 'Europe'\"<\/tt><\/tt><\/div>\n

Finally, the final formula<\/strong> would look like:<\/p>\n

Document.categoryMax('PAI<\/tt>, '< @PAI:Data:Population> '<\/tt>, \"<@PAI:Data:Continent<\/tt>> = 'Europe' \"<\/tt><\/tt>)<\/tt><\/div>\n

We would obtain the data of the number of inhabitants of the country with the largest population in Europe.<\/p>\n","protected":false},"excerpt":{"rendered":"
