MS SQL のデータ テーブルにいくつかの値を保存しようとしていますが、データ型に問題があります。パラメータを使用して、これらの値を適切なデータ型に変換する必要があります
これは私のテーブルです、、、
これは、データベースに値を渡すために使用しているコードです。パラメータを使用してデータを変換する必要があります。それを行うのを手伝ってください...
private void InsertRec(StringCollection sc)
{
var conn = new SqlConnection(GetConnectionString());
var sb = new StringBuilder(string.Empty);
var splitItems = (string[])null;
foreach (string item in sc)
{
const string sqlStatement =
"INSERT INTO DEL_PurchasesLines1 (DealerCode,InvoiceNo,InvoiceDate,ItemIdentityCode,PurchasingPrice,DiscountRate,Discount,IssueMode,Qty,Total,ExpireDate,BatchNumber,UploadedStatus,InsertedDate,UploadedDate,Force,Principle,NewTotal) VALUES";
if (item.Contains(","))
{
splitItems = item.Split(",".ToCharArray());
sb.AppendFormat("{0}('{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}','{9}','{10}','{11}','{12}','{13}','{14}','{15}','{16}','{17}','{18}'); ", sqlStatement, splitItems[0], splitItems[1], splitItems[2], splitItems[3], splitItems[4], splitItems[5], splitItems[6], splitItems[7], splitItems[8], splitItems[9], splitItems[10], splitItems[11], splitItems[12], splitItems[13], splitItems[14], splitItems[15], splitItems[16], splitItems[17]);
}
}
try
{
conn.Open();
SqlCommand cmd = new SqlCommand(sb.ToString(), conn) { CommandType = CommandType.Text };
cmd.ExecuteNonQuery();
Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Script", "alert('Records Successfuly Saved!');", true);
}
catch (System.Data.SqlClient.SqlException ex)
{
string msg = "Insert Error:";
msg += ex.Message;
throw new Exception(msg);
}
finally
{
conn.Close();
}
}
これは、クエリに値を取り込む方法です。
