let queryString = SELECT table1.*, group_concat(documents.url) as documentsUrl FROM table1 LEFT JOIN documents ON table1.Id = documents.table1_fk group by table1.Id;

    if (payload.searchString) {
        queryString += ` WHERE firstName LIKE '%${payload.searchString}%' OR lastName LIKE '%${payload.searchString}%'`;
    }
    if (payload.sortColumn) {
        queryString += ` ORDER BY ${payload.sortColumn} ${payload.sortOrder}`;
