Sometime we do need to know the number of records fetching through X++ query and this can be achieved by SysQuery::CountRecords(QueryRun) function.
This function works similar to this X++ logic;
However, this SysQuery::CountRecords(QueryRun) function count only the number of records of the first datasource. Let's assume if we need to count number of records of a query with more than one datasource, we need to use SysQuery::CountLoops(QueryRun) function.
This function works similar to this X++ logic;
ProjTable projTable;
select count(RecId) from projTable;info(strFmt("%1 total records", projTable.RecId)); // total tecords 1130
Lets see with X++ query;
static void CountProjTableRecords(Args _args)
{
Query query = new Query();
QueryRun queryRun;
QueryBuildDataSource qbd;
qbd = query.addDataSource(tablenum(ProjTable));
queryRun = new QueryRun(query);
info(strfmt("Total Records in Query %1", SysQuery::countTotal(queryRun))); // total tecords 1130
qbd = query.addDataSource(tablenum(ProjTable));
queryRun = new QueryRun(query);
info(strfmt("Total Records in Query %1", SysQuery::countTotal(queryRun))); // total tecords 1130
}
