PHP код:
Query q = new Query();
;
q.AddDataSource(tablenum(BankAccountTable));
q.DataSourceTable(tablenum(BankAccountTable)).AddDataSource(tablenum(BankGroup));
q.DataSourceTable(tablenum(BankGroup)).ClearLinks();
q.DataSourceTable(tablenum(BankGroup)).
AddLink(fieldnum(BankAccountTable, BankGroupId), fieldnum(BankGroup, BankGroupId));
q.DataSourceTable(tablenum(BankGroup)).AddRange(fieldnum(BankGroup, VendAccount)).value(LRA_ReestrTransh.VendAccount);
Где-то так, если я правильно вас понял
