I am getting an error while updating the data, the error says: "Syntax error (missing operator) in query expression '[Code] IN('."
Here is the code where i am getting an error at:
OleDbDataReader dReader = cmd.ExecuteReader();
Here is the full code of the function that the error is appear:
private void UpdateQuantity()
{
int index = 0;
string command = "UPDATE [Seranne] SET [Quantity] ='" + newVal + "' WHERE [Code] IN(";
OleDbConnection conn = new OleDbConnection(connectionString);
conn.Open();
OleDbCommand cmd = new OleDbCommand(command, conn);
cmd.Parameters.Add("Quantity", System.Data.OleDb.OleDbType.Integer);
OleDbDataReader dReader = cmd.ExecuteReader();
while (dReader.Read())
{
if (textBoxQuantityContainer[index].Value != 0 && textBoxQuantityContainer[index].Value >= Convert.ToDecimal(dReader["Quantity"].ToString()))
{
newVal = Convert.ToDecimal(dReader["Quantity"].ToString()) - textBoxQuantityContainer[index].Value;
}
System.Media.SoundPlayer sound = new System.Media.SoundPlayer(@"C:\Windows\Media\Windows Notify.wav");
sound.Play();
MessageBox.Show("Updated Successfully", "Success");
index += 1;
}
conn.Close();
dReader.Close();
}
Here is the previous code where the query expression "Code IN":
string query = "SELECT [Quantity], [Description], [Price] FROM [Seranne] WHERE [Code] IN (";
OleDbConnection conn = new OleDbConnection(connectionString);
conn.Open();
if (int.TryParse(this.textBoxCodeContainer[0].Text, out codeValue))
{
query = query + codeValue.ToString();
}
for (int i = 1; i < 17; i++)
{
if (int.TryParse(this.textBoxCodeContainer[i].Text, out codeValue))
{
query = query + "," + codeValue.ToString();
}
}
query = query + ")";
OleDbCommand cmd = new OleDbCommand(query, conn);
cmd.Parameters.Add("Code", System.Data.OleDb.OleDbType.Integer);
cmd.Parameters.Add("Quantity", System.Data.OleDb.OleDbType.Integer);
OleDbDataReader dReader;
dReader = cmd.ExecuteReader();
while (dReader.Read())
{
if (textBoxCodeContainer[index].TextLength != 0)
{
this.textBoxQuantityContainer[index].Maximum = Convert.ToDecimal(dReader["Quantity"].ToString());
this.textBoxDescContainer[index].Text = dReader["Description"].ToString();
this.textBoxSubTotalContainer[index].Text = dReader["Price"].ToString();
}
index += 1;
}
conn.Close();
dReader.Close();
Thanks a bunch!
