Can somebody tell me why the else condition is not working in the code below.
The link button in asp.net web application has following code in code behind: a parameterized SqlCommand fetch a row from a SQL Server database, the SqlDataReader rdr1.HasRows in if condition is working fine but else condition did not work.

I'm trying to enter data into the database from a DataGridView. I have 3 columns that contain Date.
When I try to insert to database I get the error:
Conversion failed when converting date and/or time from character string
With this I format the columns that show the date:
private void Import()
{
if (textBox4.Text.Trim() != string.Empty)
{
try
{
DataTable dt = GetDataTable(textBox4.Text);
dataGridView2.DataSource = dt.DefaultView;
dataGridView2.Columns[6].DefaultCellStyle.Format = "dd/mm/yyyy";
dataGridView2.Columns[8].DefaultCellStyle.Format = "dd/mm/yyyy";
dataGridView2.Columns[15].DefaultCellStyle.Format = "dd/mm/yyyy";
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
}
}
With this part, I enter the data in the database from a DatagridView:
string constring = ConfigurationManager.ConnectionStrings["db"].ConnectionString;
SqlConnection con = new SqlConnection(constring);
if (con.State == ConnectionState.Closed)
con.Open();
for (int i = 0; i < dataGridView2.Rows.Count; i++)
{
try
{
SqlCommand sqlCmd = new SqlCommand("insert into abonament (nr, serie, cui, client, sim, data_inst, activare, data_exp, telefon, nr_activat, nr_zile, ob, tip_client, email, datacurenta1, semnatura) values ('" + dataGridView1.Rows[i].Cells[0].Value + "','" + dataGridView1.Rows[i].Cells[1].Value + "','" + dataGridView1.Rows[i].Cells[2].Value + "','" + dataGridView1.Rows[i].Cells[3].Value + "','" + dataGridView1.Rows[i].Cells[4].Value + "','" + dataGridView1.Rows[i].Cells[5].Value + "','" + dataGridView1.Rows[i].Cells[6].Value + "','" + dataGridView1.Rows[i].Cells[7].Value + "','" + dataGridView1.Rows[i].Cells[8].Value + "','" + dataGridView1.Rows[i].Cells[9].Value + "','" + dataGridView1.Rows[i].Cells[10].Value + "','" + dataGridView1.Rows[i].Cells[11].Value + "','" + dataGridView1.Rows[i].Cells[12].Value + "','" + dataGridView1.Rows[i].Cells[13].Value + "','" + dataGridView1.Rows[i].Cells[14].Value + "','" + dataGridView1.Rows[i].Cells[15].Value + "')", con);
sqlCmd.ExecuteNonQuery();
MessageBox.Show("ok");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "error");
}
}
this was my solution
for (int i = 0; i < dataGridView2.RowCount; i++)
{
DateTime d1 = Convert.ToDateTime(dataGridView2.Rows[i].Cells[6].Value.ToString());
string format = "s";
DateTime d2 = Convert.ToDateTime(dataGridView2.Rows[i].Cells[8].Value.ToString());
DateTime d3 = Convert.ToDateTime(dataGridView2.Rows[i].Cells[15].Value.ToString());
try

I've tried all the solutions I could find to this problem, but for some reason I still get an exception stating the database I'm using is locked.
My code is as follows:
string connectionString = "Data Source=D:\\CCIW\\LCM\\Organisational Database\\OrganisationalDB;" +
"MultipleActiveResultSets=True";
using (SQLiteConnection OriginatorDBConnection = new SQLiteConnection(connectionString))
{
string originatorName, originatorOrganisation, originatorAddress, originatorCellNumber, originatorTelNumber, originatorEmail;
originatorName = originatorNameTextBox.Text;
originatorOrganisation = originatorOrganisationTextBox.Text;
originatorAddress = originatorAddressRichTextBox.Text;
originatorCellNumber = originatorCellTextBox.Text;
originatorTelNumber = originatorTelTextBox.Text;
originatorEmail = originatorEmailTextBox.Text;
OriginatorDBConnection.Open();
string originatorINSERT = "INSERT INTO Originator (Name, Organisation, Address, CellphoneNumber, TelephoneNumber, Email) VALUES ('" + originatorName + "', '" + originatorOrganisation + "', '" + originatorAddress + "', '" + originatorCellNumber + "', '" + originatorTelNumber + "', '" + originatorEmail + "');";
using (SQLiteCommand originatorCommand = new SQLiteCommand(originatorINSERT, OriginatorDBConnection))
{
originatorCommand.ExecuteNonQuery();
}
OriginatorDBConnection.Close();
}
The closest solution on here that I could find to the problem was here: SQLite Database Locked exception
It didn't seem to work on my problem, however.
What am I doing wrong?
I have an additional function wherein I use the connection:
public AdminForm()
{
//Initialise AdminForm components.
InitializeComponent();
//Establish and open connection to ObservationDB.
string connectionString = "Data Source=D:\\CCIW\\LCM\\Organisational Database\\OrganisationalDB;" +
"MultipleActiveResultSets=True";
ObservationDBConnection = new SQLiteConnection(connectionString);
ObservationDBConnection.Open();
//Query database to find all originators
string originatorSELECT = "SELECT * FROM Originator;";
string ECPNumberSELECT = "SELECT * FROM ECP";
SQLiteCommand command = new SQLiteCommand(originatorSELECT, ObservationDBConnection);
SQLiteDataReader reader = command.ExecuteReader();
SQLiteCommand command2 = new SQLiteCommand(ECPNumberSELECT, ObservationDBConnection);
SQLiteDataReader reader2 = command2.ExecuteReader();
//Populate OriginatorName combobox with names of existing originators.
List<string> originatorNames = new List<string>();
while (reader.Read())
{
originatorNames.Add(Convert.ToString(reader["Name"]));
}
OriginatorNameComboBox.DataSource = originatorNames;
//Populate ECP combobox with numbers of existing ECP.
List<string> ECPNumbers = new List<string>();
while (reader2.Read())
{
ECPNumbers.Add(Convert.ToString(reader2["Number"]));
}
ECPNumComboBox.DataSource = ECPNumbers;

I know I'm a lot late to the game, but it looks like you're not closing you reader variables in AdminForm() constructor. Consider wrapping the DataReaders in a using().
Wrapping around Command and Reader did work for me:
using (SqliteCommand cmd = new SqliteCommand(sQuery, m_Conn))
{
using (SqliteDataReader reader = cmd.ExecuteReader())
{
if (reader.Read())
{
ret_type = reader.GetInt32(0);
}
}
}
Please be aware to click on Write changes on SQLite browser if it is running and there are any unsaved changes!
In my case it was very stupid of me, I was making changes in SQLite browser and did not click on write changes, which locked the DB to be modified by the services. After I clicked the Write changes button, all the post request worked as expected.
According to #Rohan Shenoy in this topic: SQLite Database Locked exception
how to save imported data from excel in datagridview to database in C#
I have saved records and exported to excel sheet, it exported along with data ID, now I have re-imported back to datagridview from excel. now I want to save data to database.
Important to know:
Database name "Records.sdf" using SQL Compact 3.5
DataGridViewName is RecordsDataGridView.
I'm using following code but it's not working.
public void SaveData()
{
// Save the data.
SqlCeConnection conn =
new SqlCeConnection(
#"Data Source=|DataDirectory|\Records.sdf;Persist Security Info=False");
SqlCeCommand com;
string str;
conn.Open();
for (int index = 0; index < RecordsDataGridView.Rows.Count - 1; index++)
{
str = #"Insert Into OutgoingChequeRecords(ID,BankName,Date,AccountNo, Chequebook, ChequeNo, Payee, Amount, Remarks) Values(" + RecordsDataGridView.Rows[index].Cells[0].Value.ToString() + ", '" + RecordsDataGridView.Rows[index].Cells[1].Value.ToString() + "'," + RecordsDataGridView.Rows[index].Cells[2].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[3].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[4].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[5].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[6].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[7].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[8].Value.ToString() + ")";
com = new SqlCeCommand(str, conn);
com.ExecuteNonQuery();
}
conn.Close();
}
ERROR RECEIVING
Column Name not Valid, column name = Cash
Try this query string
str = #"Insert Into OutgoingChequeRecords(ID,BankName,Date,AccountNo, Chequebook, ChequeNo, Payee, Amount, Remarks) Values(" + RecordsDataGridView.Rows[index].Cells[0].Value.ToString() + ",'"+ RecordsDataGridView.Rows[index].Cells[1].Value.ToString() + "'," + RecordsDataGridView.Rows[index].Cells[2].Value.ToString() + ",'" + RecordsDataGridView.Rows[index].Cells[3].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[4].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[5].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[6].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[7].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[8].Value.ToString() + "')";
You should pass varchar field enclosed with single quote.
var str = #"Insert Into OutgoingChequeRecords(ID,BankName,Date,AccountNo, Chequebook, ChequeNo, Payee, Amount, Remarks) Values("
+ RecordsDataGridView.Rows[index].Cells[0].Value.ToString() + ", '"

+ RecordsDataGridView.Rows[index].Cells[7].Value.ToString() + ","
+ "'" + dataGridView1.Rows[index].Cells[8].Value.ToString() + "'" + ")";
There are a few ways to do this.
Here is one method.
private void save_btn_Click(object sender, EventArgs e)
{
sAdapter.Update(sTable);
dataGridView1.ReadOnly = true;
save_btn.Enabled = false;
new_btn.Enabled = true;
delete_btn.Enabled = true;
}
http://csharp.net-informations.com/datagridview/csharp-datagridview-database-operations.htm
You can do this as well.
string StrQuery;
try
{
using (SqlConnection conn = new SqlConnection(ConnString))
{
using (SqlCommand comm = new SqlCommand())
{
comm.Connection = conn;
conn.Open();
for(int i=0; i< dataGridView1.Rows.Count;i++)
{
StrQuery= #"INSERT INTO tableName VALUES ("
+ dataGridView1.Rows[i].Cells["ColumnName"].Text+", "
+ dataGridView1.Rows[i].Cells["ColumnName"].Text+");";
comm.CommandText = StrQuery;
comm.ExecuteNonQuery();
}
}
}
}
Something like this will work too.
private void buttonSave_Click_1(object sender, EventArgs e) // save to invoice
{
SqlConnection con = new SqlConnection(MyConnectionString);
string SqlCmdText = "INSERT INTO invoice (p_code, p_name, p_category, p_price) " +
VALUES (#code, #name, #category, #price)";
SqlCommand sc = new SqlCommand(SqlCmdText, con);
con.Open();
foreach (DataRow row in MyTable.Rows)
{
sc.Parameters.Clear();
sc.Parameters.AddWithValue("#code", row["p_code"]);
sc.Parameters.AddWithValue("#name", row["p_name"]);
sc.Parameters.AddWithValue("#category", row["p_category"]);
sc.Parameters.AddWithValue("#price", row["p_price"]);
sc.ExecuteNonQuery();
}
con.Close();
}

I am trying to get date from my database into a string and comparing it with the today's date to perform some operation.
What I did as a solution but still the label isn't displaying the messages.
if (FileUpload1.PostedFile != null)
{
string FileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
//Save files to disk
FileUpload1.SaveAs(Server.MapPath("Files/" + FileName));
string FilePath = "Files/" + FileName;
//SqlCommand cmd = new SqlCommand();
DAL obj = new DAL();
using (SqlConnection conn = obj.openCon())
{
String sql = "Select DueDate from tbl_AssignmentUpload1 where AssignmentTitle like '" + AssignmentTitle + "'";
SqlCommand cmd = new SqlCommand(sql, conn);
SqlDataReader dr = cmd.ExecuteReader();
DateTime duedate = new DateTime() ;
if (dr != null && dr.HasRows)
{
while (dr.Read())
{
duedate = dr.GetDateTime(0);
}
dr.Close();
// now check if today greater than due date and update
if (duedate != null && today.Date > duedate)
{
sql = "Insert into tbl_AssignmentSubmit( Name ,AridNumber, Shift , Degree , Course , FileName ,FilePath ) values ('" + txt_Name.Text + "' , '" + txt_AridNumber.Text + "', '" + shift + "', '" + Degree + "', '" + Course + "','" + FileName + "','" + FilePath + "')";
cmd = new SqlCommand(sql, conn);
cmd.ExecuteNonQuery();
}
else
{
lbl_uploaded.Text = "Assignment can not be Submitted.You crossed the due date.";
}
}
}
}
You have to get DueDate from tbl_AssignmentUpload1 .
For example :
string strSQL = "Select DueDate from tbl_AssignmentUpload1 where AssignmentTitle like #AssignmentTitle ";
(SqlCommand myCommand = new SqlCommand(strSQL, cnn)) // Cnn is your sql connection
{
myCommand.Parameters.AddWithValue("#AssignmentTitle", AssignmentTitle );
using (SqlDataReader reader = myCommand.ExecuteReader())
{
while (reader.Read())
{
DateTime today1 = Convert.ToDateTime(reader["DueDate "].ToString());
}
}
}
After this you can do your insert statement
Try something like this. Ok updated with the fix for duedate.
using (SqlConnection conn = SQL.GeSQLConnection())
{
String sql = "Select DueDate from tbl_AssignmentUpload1 where AssignmentTitle like '" + AssignmentTitle + "'";
SqlCommand cmd = new SqlCommand(sql, conn);
SqlDataReader dr = cmd.ExecuteReader();
DateTime duedate = new DateTime();
if (dr != null && dr.HasRows)
{
while (dr.Read())
{
duedate = dr.GetDateTime(0);
}
dr.Close();
// now check if today greater than due date and update
if(duedate != null && DateTime.Today > duedate)
{
sql = "Insert into tbl_AssignmentSubmit( Name ,AridNumber, Shift , Degree , Course , FileName ,FilePath ) values ('" + txt_Name.Text + "' , '" + txt_AridNumber.Text + "', '" + shift +"', '" + Degree + "', '" + Course + "','" + FileName + "','" + FilePath + "')";
cmd = new SqlCommand(sql, conn);
cmd.ExecuteNonQuery();
}
else
{
lbl_uploaded.Text = "Assignment can not be Submitted.You crossed the due date.";
}
}
else
{
lbl_uploaded.Text = "No Due date was selected for the given assesment title";
}
}
