Usage Notes

notExistsJoin is a method of the following classes:

The library functions for building the notExistsJoin parameters are as follows:


// It filters out {'r1':2, 'k1':'b'} in p1 as value 'b' doesn't exist in column 'k2' of p2
const op = require('/MarkLogic/optic');

const p1 = op.fromLiterals([
    {'r1':1, 'k1':'a'},
    {'r1':2, 'k1':'b'}
const p2 = op.fromLiterals([
    {'r2':3, 'k2':'a'},
    {'r2':4, 'k2':'c'}
p1.notExistsJoin(p2, op.on('k1', 'k2')).result();
