Using SysDa framework to work with X++ queries with date & time with class SysDaValidTimeStateDateTimeRange

Chaitanya Golla Profile Picture Chaitanya Golla 17,225

Hi,

In this post will showcase the code where we can use SysDa framework with the help of class SysDaValidTimeStateDateTimeRange to deal with data and time in X++ queries.

Note: CG_SysDaQueryTime is a runnable class.

class CG_SysDaQueryTime
{       
 
    /// <summary>
    /// SysDaQueryObject - Implementing time function.
    /// </summary>
    /// <param name = "_args">The specified arguments.</param>
    public static void main(Args _args)
    {       
        /*
            Effective X++ Statement(s)/code -
            public static HcmEmployment find(HcmWorkerRecId     _worker,
                                             CompanyInfoRecId   _legalEntity,
                                             Utcdatetime        _validFrom = DateTimeUtil::minValue(),
                                             Utcdatetime        _validTo   = DateTimeUtil::maxValue(),
                                             boolean            _forUpdate = false)
            {
                HcmEmployment hcmEmployment;
                utcdatetime validFrom, validTo;
                validFrom = DateTimeUtil::minValue();
                validTo   = DateTimeUtil::maxValue();
 
                if (_worker && _legalEntity)
                {
                    if (_forUpdate)
                    {
                        hcmEmployment.selectForUpdate(_forUpdate );
                    }
 
                    select firstonly ValidTimeState(validFrom, validTo) hcmEmployment
                        where hcmEmployment.Worker == _worker
                            && hcmEmployment.LegalEntity = _legalEntity;
                }
               
                return hcmEmployment;
            }
        */
 
        HcmPersonnelNumberId    personnelNumber = "0001";
        DirPersonName           dirPersonName;
        CompanyInfo             companyInfo;
        HcmEmployment           hcmEmployment;
 
        companyInfo = CompanyInfo::find();
        hcmEmployment = CG_SysDaQueryTime::find(HcmWorker::findByPersonnelNumber(personnelNumber).RecId,
                                                companyInfo.RecId,
                                                DateTimeUtil::utcNow(),
                                                DateTimeUtil::utcNow());
        #File
 
        if (hcmEmployment.RecId != 0)
        {
            dirPersonName =  DirPersonName::find(DirPerson::find(HcmWorker::find(hcmEmployment.Worker).Person).RecId);
            info(strFmt("Worker %1 actively exists in legal entity %2", dirPersonName.FirstName, companyInfo.DataArea));
        }
    }
 
    public static HcmEmployment find(HcmWorkerRecId     _worker,
                                     CompanyInfoRecId   _legalEntity,
                                     Utcdatetime        _validFrom = DateTimeUtil::minValue(),
                                     Utcdatetime        _validTo   = DateTimeUtil::maxValue(),
                                     boolean            _forUpdate = false)
    {
        HcmEmployment       hcmEmployment;
        SysDaQueryObject    sysDaQuery = new SysDaQueryObject(hcmEmployment);
 
        if (_worker && _legalEntity)
        {
            if (_forUpdate)
            {
                // Select for update
                sysDaQuery.forUpdateHint = true;
            }
 
            // Imposes optimistic lock
            sysDaQuery.optimisticLockHint = true;
 
            // Select firstonly
            sysDaQuery.firstOnlyHint = true;
 
            sysDaQuery.whereClause(new SysDaEqualsExpression
                                (new SysDaFieldExpression(HcmEmployment, fieldStr(HcmEmployment, Worker)),
                                 new SysDaValueExpression(_worker)));
           
            SysDaFindObject findObject = new SysDaFindObject(sysDaQuery);
 
            SysDaValidTimeStateDateTimeRange    sysDaValidDateTime = new SysDaValidTimeStateDateTimeRange(_validFrom, _validTo);
            findObject.validTimeState(sysDaValidDateTime);
 
            new SysDaFindStatement().execute(findObject);
        }
 
        return hcmEmployment;
    }
 
}
Result: Output
