MarkLogic 9 Product Documentationtemporal.setUseLsqt
temporal.setUseLsqt( temporal-collection as String, on as Boolean ) as null
Summary
This function enables or disables the use of LSQT (Last Stable Query Time) on the named collection. When enabled (true), a document is created in the database to hold the LSQT. This document is identified by the collection name with an .lsqt suffix.
You must have LSQT enabled on the temporal collection in order to use the
temporal:statement-set-system-time
function to manually set the system start time when inserting a document
into that collection.
For details on how to use LSQT, see Last Stable Query Time (LSQT) and Application-controlled System Time in the Temporal Developer's Guide
| Parameters | |
|---|---|
| temporal-collection | The name of the temporal collection. |
| on |
Set to fn:true() to enable LSQT on the collection
or fn:false()
(the default) to disable LSQT.

Example
declareUpdate();
var temporal = require("/MarkLogic/temporal.xqy");
temporal.setUseLsqt("kool", true);
// Set the temporal collection, "kool", to use LSQT. A document, named
// "kool.lsqt", that contains the latest LSQT is created in the database.
// Requires the specified temporal collection to exist. Use
// temporal.collectionCreate to create the temporal collection.
