Dynamic Query Using Aggregative Functions and Joins

Hi All,

Here i written the code to use the Aggregate functions and Joins inDynamic Query in spite of using normal Select statement in Ax 2009

Normal Select Statement:

while select sum(qty) from inventTrans where inventTrans.ItemId ==

“OL-2500” join inventDimgroup by inventBatchId where

inventDim.InventDimId == inventTrans.InventDimId

{

// Our Code Here

}

Dynamic Query:

static void Vasanth_Query_Eg1(Args _args)

{

Query                   query;

QueryBuildDataSource    queryBuildDataSource;

QueryBuildRange         queryBuildRange;

QueryRun                queryRun;

Qty                     total;

InventTrans             inventTrans;

;

query = new Query();    queryBuildDataSource    = query.addDataSource(tableNum(InventTrans));

queryBuildDataSource.addSelectionField(fieldNum(InventTrans,Qty),

SelectionField::Sum);

queryBuildDataSource.orderMode(OrderMode::GroupBy);

queryBuildRange         = queryBuildDataSource.addRange(fieldNum(InventTrans,ItemId));

queryBuildDataSource    = queryBuildDataSource.addDataSource(tableNum(InventDim));

queryBuildDataSource.orderMode(OrderMode::GroupBy);

queryBuildDataSource.addSortField(fieldNum(InventDim,InventBatchId));

queryBuildDataSource.relations(true);

queryRun = new QueryRun(query);

if (queryRun.prompt())

{

while (queryRun.next())

{

inventTrans = queryRun.get(tableNum(InventTrans));

total = inventTrans.Qty;

}

}

info(strFmt(“Quantity: %1″, total));
}
