op:remove

op:remove(
   [$removeCol as item()?]
) as map:map

Summary

This method deletes a document from the database. If the document does not exist, this method does not throw an error.

Parameters
$removeCol If this column is not specified then it assumes a column 'uri' is present. This can be a string of the uri column name or an op:col. Use op:view-col or op:schema-col if you need to identify columns in the two views that have the same column name. This can also be a map object specify the uri column name.

Usage Notes

op:remove() needs to be run as an update transaction. Use 'declare option xdmp:update "true";' in the prolog, or use xdmp:invoke/xdmp:invoke-function with update="true".
