op:result(
   $plan as map:map,
   [$outType as xs:string?],
   [$bindings as map:map],
   [$options as xs:sring*]
) as xs:string?

Summary

This method executes the plan (mapping or reducing, if specified) to generate the result, which is a sequence of map:map or json:array rows, unless mapped or reduced to different output.

Parameters
$plan	The Optic Plan. You can either use the XQuery => chaining operator or specify the variable that captures the return value from the previous operation.
$outType	This parameter specifies the outputType as either "object" (the default) for a `map:map` sequence with keys of the column names and values of the column values or "array" for a `json:array` with the list of column names as an initial header and the column values in the same order for the subsequent rows.
$bindings	This parameter provides a map with the names and values of placeholder parameters. An error is thrown if a placeholder parameter is not bound.
$options	Options as an array of string values. Available options are: "errors-only" Return only the errors caused by Optic Update operations. This is useful when a `op:on-error("continue")` error handler is used "trace=ID" This parameter outputs the query's plan, optimization and execution details in the log while getting results. ID is the identifier to identify the query in the logs. "optimize=N" Sets the optimization level to use. Levels of 0 (off), 1, and 2 are recognized. The default is 1. "seed=N" Sets the seed to use. The default will generate a random seed. Setting it to 0 will behave the same as the default case. The default is 0.

Example

xquery version "1.0-ml";

import module namespace op="http://marklogic.com/optic"
     at "/MarkLogic/optic.xqy";

op:from-view("main", "employees")
   => op:select(("EmployeeID", "FirstName", "LastName"))
   => op:order-by("EmployeeID")
   => op:result((), (), ("trace=myQuery", "optimize=1"))
