temporal.axisCreate

temporal.axisCreate(
   axis-name as String,
   start-range-index as cts.reference,
   end-range-index as cts.reference
) as (Number|String)

Summary

This function constructs an axis definition based on the existing range indexes that can be added to a temporal collection in subsequent API calls. The axis definition is stored in the schema database.

For details on how to create an axis, see Create System and Valid Axes

A TEMPORAL-NONDATETIME exception is thrown if range index scalar type is not dateTime. A TEMPORAL-DUPAXIS exception is thrown if the axis already exists.

Parameters
axis-name The name to be used to identify the axis.
start-range-index A reference to a range index to be used as the start of the time period.
end-range-index A reference to a range index to be used as the end of the time period.

Example

const temporal = require("/MarkLogic/temporal.xqy");

temporal.axisRemove("system");
temporal.axisRemove("valid");
const output = new Array();
output.push(
  temporal.axisCreate(
   "system",
   cts.elementReference(xs.QName("systemStart")),
   cts.elementReference(xs.QName("systemEnd"))) 
  );

output.push(
  temporal.axisCreate(
   "valid",
   cts.elementReference(xs.QName("validStart")),
   cts.elementReference(xs.QName("validEnd"))) 
  );
output;

// First removes, then creates two axes, named "system" and "valid",
// from the element range indexes, "systemStart", "systemEnd",
// "validStart", and "validEnd".  Then it returns the IDs of the
// new axes.
