Solution 1

Hi,

Can you change the type of @Activedate to datetime and see whether it is getting solved. You need to make corresponding type changes in your C# code also.

Regards
Sebastian

Tried but showing same error....

StianSandberg · Answer 2 · 2012-07-16T19:41:00

You are sending your date as a varchar

C#

cmd1.Parameters.AddWithValue("@Activedate", SqlDbType.VarChar).Value = date;

and putting @tblActiveSubBroker into your procedure as varchar. Then you try to convert it to a date on insert to table.
This is not a good approach.You should do the converting in your code before sending it to sql.

C#

var myDate = DateTime.Parse("whatever");
cmd1.Parameters.AddWithValue("@Activedate", SqlDbType.DateTime).Value = myDate ;

Hello thanks for rewrite.
You can try it as like...........
protected void btnsave_Click1(object sender, EventArgs e)
{
Label1.Visible = true;
string tbname = "tblActiveSubBroker"; //dataset .. used 2 stored. then move dataset to .. grid..
string filename = Path.GetFileName(FileUpload1.FileName);
try
{
string fileName = string.Empty;
if (FileUpload1.HasFile)
{

fileName = FileUpload1.PostedFile.FileName;

string file_ext = Path.GetExtension(fileName);
if (file_ext.Trim().ToLower() == ".csv")
{
FileUpload1.Controls.Clear();

string line = null; int i = 0;
string imgMap;
imgMap = ConfigurationSettings.AppSettings["imageFolderMap"].ToString();

// save file on server then upload serfile on database and delete server file
strPath = imgMap + Path.GetFileName(fileName);
if (!Directory.Exists(imgMap))
{

Directory.CreateDirectory(imgMap);
}
//else
//{
// Directory.Delete(imgMap);
// Directory.CreateDirectory(imgMap);

//}

FileUpload1.PostedFile.SaveAs(strPath);

using (StreamReader sr = File.OpenText(strPath))
{
while ((line = sr.ReadLine()) != null)
{
string[] data = line.Split(',');
if (data.Length > 0)
{
if (i == 0)
{

foreach (object item in data)
{
{

dt.Columns.Add(new DataColumn());

}
}

i++;
}
DataRow row = dt.NewRow();
row.ItemArray = data;
dt.Rows.Add(row);

}
}
}

int count = dt.Rows.Count;
int index = 0;
//int currentindex = 0;

for (index = 0; index < count; index++)
{
string code = dt.Rows[index][1].ToString();
string date = dt.Rows[index][2].ToString(); // Your Code

con = new SqlConnection("Data Source=192.168.0.187;Initial Catalog=mis;Persist Security Info=True;User ID=sa;Password=ms");
cmd.Connection = con;
con.Open();

SqlCommand cmd1 = new SqlCommand("Usb_fileupload", con);
cmd1.CommandType = System.Data.CommandType.StoredProcedure;
cmd1.CommandTimeout = 10000;
SqlDataAdapter da = new SqlDataAdapter(cmd1);
cmd1.Parameters.Clear();
cmd1.Parameters.AddWithValue("@Sub_Code", SqlDbType.VarChar).Value = code;

cmd1.Parameters.AddWithValue("@Activedate", SqlDbType.VarChar).Value =Convert.ToDateTime( date);
cmd1.ExecuteNonQuery();
con.Close();
Label1.Text = "Data Inserted successfully";

}

}
//Past here renaming code

sanwar_mal_jat 18-Jul-12 2:24am

And use your stored procedure as like .................

alter procedure Usb_fileupload

(
@Sub_Code varchar(50),
-- @Activedate varchar(50) Your Code
@Activedate datetime
)
as
begin
if((select count(*) from tblActiveSubBroker where Sub_Code=@Sub_Code)<1 and @Sub_Code<>'')

insert
into
tblActiveSubBroker
(
Sub_Code,
Activedate
)
values
(

@Sub_Code,
--convert(datetime,@Activedate,103) your code
@Activedate
)
end

thanks sanwar mal jat

But it is still showing same error Pls help

sanwar_mal_jat 18-Jul-12 3:02am

can u tell me result of date in this code ----- string date = dt.Rows[index][2].ToString();

pratham2587 18-Jul-12 3:04am

as i am trying to debug the code it is not coming on that debugger it is directly going on catch and giving the above error

sanwar_mal_jat 18-Jul-12 3:13am

Apply your Break point here Label1.Visible = true; and then debug and tell me where throw in catch block...

pratham2587 18-Jul-12 3:23am

using (StreamReader sr = File.OpenText(strPath))
{
while ((line = sr.ReadLine()) != null)
{
string[] data = line.Split(',');
if (data.Length > 0)
{
if (i == 0)
{

foreach (object item in data)
{
{

dt.Columns.Add(new DataColumn());

}
}

i++;
}
DataRow row = dt.NewRow();
row.ItemArray = data;
dt.Rows.Add(row);

}
}
}

After Debugging it goes till this code and after jumps directly to catch statement showing thata error.....
