I'm trying to filter the table by the field "LanguageId" to show only "fr". I made a new method in my form datasource Here is my code
public void filtr()
{
DirPartyTable _dirPartyTable;
select LanguageId from _dirPartytable
where _dirPartyTable.LanguageId == "fr";
}
When running this code nothing happens. How to invoke it to work?
您可以覆盖DirPartyTable数据源的init方法,并添加以下代码以在languageId上添加值“ fr”的范围:
SysQuery::findOrCreateRange(this.query().dataSourceTable(tableNum(DirPartyTable)), fieldNum(DirPartyTable, LanguageId)).value("fr");
