Builder C ++ DBExpress clientdataset：此操作的内存不足

Question

当我尝试从数据源填充DBGrid时遇到问题：

我的代码

void MyClass::initializeGridView()
{
    String sqlFilter = SrcQryStringList->Text + QueryStringList->Text;

    FilterSQLQuery->Close();
    FilterSQLQuery->SQL->Clear();
    FilterSQLQuery->SQL->Add(sqlFilter);
    FilterSQLQuery->Active = true;

    DocumentsDataSetProvider = new TDataSetProvider(this) ;
    DocumentsDataSetProvider->DataSet = FilterSQLQuery;
    DocumentsDataSetProvider->Name ="DocumentsDataSetProvider";

    DocumentsClientDataSet = new TClientDataSet(this);
    DocumentsClientDataSet->ProviderName = DocumentsDataSetProvider->Name ;
    DocumentsClientDataSet->Active = true; // "insufficient memory for this operation"


    DocumentsDataSource= new TDataSource (this);
    DocumentsDataSource->DataSet = DocumentsClientDataSet;

    JvDBGrid1->DataSource =  DocumentsDataSource;

    delete DocumentsDataSetProvider;
}

FilterSQLQuery是一个TSQLQuery，JvDBGrid1是一个DBgrid

我收到此错误＆＃34;此操作的内存不足＆＃34;返回行数很高！
