(0) ShareShare

Posted on by ShaqAX 709

Hello guys,

A newbie, if I have a View in my AOT that I want to add Range that only include field that it is empty. What I need to type in Range ?

The field itself is a string datatype.

Currently I put something like this but it seems not working:

It's a Data entity view, btw

Thanks.

    Hi ShaqAX,

    You could try to add range in the onInitializedEntityDataSource event.

    FormDatasource fb = _sender.dataSource();
QueryBuildDataSource qbd= fb.query().dataSourceTable(tableNum(SalesTable));
qbd.addRange(fieldNum(SalesTable, Stringfield)).value(queryValue(""));

    Hi ShaqAX,

    You can use an advanced filter function and place value (SysQueryRangeUtil::valueEmptyString()) into value property.

    It should work for empty strings (null values are a different case).

    If I was you, I would look at T-SQL code defining the view (through SQL Server Management Studio) and debugged this code directly. When I knew how I wanted to change T-SQL, I would go back to AX and change the view definition.
