A DataTable or a DataView must be supplied. Hint: if that is TFDMemTable, use CreateDataSet or CloneCursor to open dataset.错误的原因

使用如vFDMemTable.CopyDataSet(vTempABQuery);这样复制数据集会出现如下错误：

//vFDMemTable.CopyDataSet(vTempABQuery);

改为：

vFDMemTable.CopyDataSet(vTempABQuery,[coStructure, coRestart, coAppend]);
vFDMemTable.Open;
即可
