An instance of the DataTransfer data type.

Note

Copying the SystemID and data audit fields using CopyRows is supported in Business Central version 21.5 and later.

Example

In this code example, you copy the PK and S3 fields in the Source table for all rows where S2 equals A and add them as new rows in the Destination table. You use AddConstantValue method to give the field D2 the value X in the inserted rows.

local procedure CopyRows()
var
    dt: DataTransfer;
    src: Record Source;
    dest : Record Destination;
begin
    dt.SetTables(Database::Source, Database::Destination);
    dt.AddFieldValue(src.FieldNo("PK"), dest.FieldNo("PK"));
    dt.AddFieldValue(src.FieldNo("S3"), dest.FieldNo("D3"));
    dt.AddConstantValue('X', dest.FieldNo(D2));
    dt.AddSourceFilter(src.FieldNo("S2"), '=%1', 'A');
    dt.CopyRows();
end;
