问题 while writing code we can either use select statement or select field list or find method on table for fetching the records. I wonder which of the statement helps in better performance 回答1: It really depends on what you actually need. find() methods must return the whole table buffer, that means, all of the columns are projected into the buffer returned by it, so you have the complete record selected. But sometimes you only need a single column, or just a few. In such cases it can be a waste

问题 I need to customize AX to load an arbitrary file with arbitrary size and save it to database as a container field. I also need to read back from that container field and write the content into a file, which should contain exactly the same file content as before load.

问题 MS Dynamics AX 2009: I need to do this from the Purchase Order Screen, so I only have the Purchase Requisition number available from the PurchLines Table. Your help would be really greatly appreciated as there is nothing yet on the net available (that I can find) and there are missing classes in the AX 2009 Tutorials. All helpful answers will definitely get an upvote from me. Edit: Purpose is to force the existing workflow to re-execute on the Purchase Requisition from "Submitted" stage when

问题 This is code that should work with any base system added to Tables\ProdBOM. Somehow the query is stripping out data from fields. static void lookupItemIdBOMSubset(FormStringControl _ctrl, ProdId _prodId) { SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(ProdBOM), _ctrl); Query query = new Query(); QueryBuildDataSource qbds = query.addDataSource(tableNum(ProdBOM)); ; qbds.addRange(fieldNum(ProdBOM, ProdId)).value(queryvalue(_prodId)); qbds.addSortField(fieldNum(ProdBOM,

问题 What is the best way to convert a utcDateTime value to a date type so I can use the global datetime functions on it? int timeDiff; date _now = systemdateget(); ; select firstOnly myUTCDateTime from _myTable timeDiff = Global::yearDiff(_now, _myTable.myUTCDateTime); info(strfmt('%1', timeDiff); Thanks 回答1: The DateTimeUtil Class has methods for dealing with utcdatetime variables. In your case you would use DateTimeUtil::date . timeDiff = Global::yearDiff(_now, DateTimeUtil::date(_myTable

I can not understand why...

问题 I've found several posts and articles around the net talking about validating form fields in dialogs, but none of the examples I've found seem to work properly. Can someone post a complete, concise example of x++ code that generates a dialog containing a single text field, performs simple validation (if text = "abc") on it, and either closes the window (returning the field value) if validation passes or generates an Infolog warning without closing the dialog if validation fails. For those of

问题 How to make a query in Ax with advanced filtering (with x++): I want to make such filter criteria On SalesTable form to show SalesTable.SalesId == "001" || SalesLine.LineAmount == 100 . So result should show SalesOrder 001 AND other salesOrders which has at least one SalesLine with LineAmount = 100? 回答1: The AX select statement supports exists join such as: while select salesTable exits join salesLine where salesLine.SalesId == salesTable.SalesId && salesLine.LineAmount == 100 X++ does not
