このコードを実行しようとすると、次のエラーが発生します。
conversion failed when converting date and/or time from character string
この行でエラーが発生します:
g_muallak_tarihi = DateTime.Parse(row_muallakt["Muallak_tarihi"].ToString());
日付と時刻の両方、または日付のみの値を格納するには、DateTimeデータ型を使用します。どうしたらいいかわかりません。あなたはなにか考えはありますか?
これが私のコードです:
public void cs_hmuallak()
{
string cs_hmuallak = null;
SqlConnection cnn;
cs_hmuallak = @"Data Source= .\SQLEXPRESS; Initial Catalog=mydb;Integrated Security= True";
cnn = new SqlConnection(cs_hmuallak);
try
{
cnn.Open();
{
SqlDataAdapter da_muallakt = new SqlDataAdapter("SELECT M.Muallak_tutari FROM Muallak M INNER JOIN Hasar H ON M.Hasar_no= H.Hasar_no INNER JOIN Police P ON p.Police_no=h.Police_no where p.Acenta_kodu='"+cbx_acenta.Text+"' and p.Brans_kodu='"+cbx_brans.Text+"' and M.muallak_tarihi<=(Select M.muallak_tarihi from muallak M where M.muallak_tarihi=(select max(muallak_tarihi) from muallak where muallak_tarihi<=@parameter)) and M.Muallak_tarihi=(SELECT max(M.Muallak_tarihi) FROM Muallak M INNER JOIN Hasar H ON M.Hasar_no= H.Hasar_no INNER JOIN Police P ON p.Police_no=h.Police_no where p.Acenta_kodu='"+cbx_acenta.Text+"' and p.Brans_kodu='"+cbx_brans.Text+"' and M.muallak_tarihi<=(Select M.muallak_tarihi from muallak M where M.muallak_tarihi=(select max(muallak_tarihi) from muallak where muallak_tarihi<=@parameter)) ) ", cnn);

da_muallakt.Fill(table_muallakt);
