【问题描述】:
我尝试向 SQL DB 中的表添加新行,但遇到了问题:
不支持对多个基表进行动态 sql 生成
这是我尝试过的代码:
private MyClass myClass = new MyClass();
private SqlDataAdapter adapter;
private SqlDataAdapter adapter2;
private void GestionCollections_Load(object sender, EventArgs e)
{
adapter = new SqlDataAdapter("select Id_Collection ID, Libelle_Collection Collection,Libelle_Editeur Editeur from Collection_ left join Editeur on Id_Editeur = Collection_.Id_Editeur_Editeur", myClass.cnx);
adapter.Fill(myClass.ds, "Collection_");
adapter2 = new SqlDataAdapter("Select Id_Editeur ID,Libelle_Editeur Editeur from Editeur", myClass.cnx);
adapter2.Fill(myClass.ds, "Editeur");
}
private void AjouterBarButton_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
String newKeyWordCollectionName = ajoutCollection.KeyWordCollectionName;
String newKeyWordAEditeurName = ajoutCollection.KeyWordEditeurName;
DataRow row = myClass.ds.Tables["Collection_"].NewRow();
row[1] = newKeyWordCollectionName;
foreach(var myRow in myClass.ds.Tables["Editeur"].AsEnumerable())
{
if (newKeyWordAEditeurName == myRow[1] as String)
row[2] = (int)myRow[0];
}
myClass.ds.Tables["Collection_"].Rows.Add(row);
SqlCommandBuilder builder = new SqlCommandBuilder(adapter);
adapter.Update(myClass.ds, "Collection_");
}
