Can anybody help me? Why am I getting this error?
If I remove the 'P' from the prod_id which left only number, it can work but if I add alphabet, it says "Invalid column name".
I already added .ToString() to it, but why it still can't take varchar and only take int.
Here is my code

This is the database table
CREATE TABLE [dbo].[Product2]
(
[prod_id] VARCHAR(6) NOT NULL,
[prod_name] VARCHAR(50) NOT NULL,
[prod_price] FLOAT(53) NOT NULL,
[prod_desc] VARCHAR(120) NOT NULL,
[prod_img] NVARCHAR(MAX) NOT NULL,
[prod_cat] VARCHAR(6) NOT NULL,
[stock_count] INT NULL,
[weight] DECIMAL(9, 2) NULL,
[width] DECIMAL(9, 2) NULL,
[length] DECIMAL(9, 2) NULL,
[height] DECIMAL(9, 2) NULL,
[shipping_fee] DECIMAL(9, 2) NOT NULL,
[created_at] DATETIME NOT NULL,
[updated_at] DATETIME NULL,
[prod_status] NVARCHAR(MAX) NULL,
PRIMARY KEY CLUSTERED ([prod_id] ASC),
CONSTRAINT [FK_Product2_ToTable]
FOREIGN KEY ([prod_cat]) REFERENCES [dbo].[Category] ([cat_id])
);
The way you pass the query could lead to SQL Injection.
SqlDataAdapter da = new SqlDataAdapter("select * from Product2 where prod_id=" + Request.QueryString["Id"] , conn);
I expect the final query you want to achieve is
select * from Product2 where prod_id=`P100`
But after revise your code if you do concatenate with 'P' in your query, you will get:
select * from Product2 where prod_id=P100
In which this will return result:
Invalid column name 'P100'
String concatenation into query is dangerous that possible break your query.
You need to create a SqlCommand variable and pass it to the SqlDataAdapter.
And also use SqlParameter to pass the parameter value.
SqlCommand cmd = new SqlCommand("select * from Product2 where prod_id = #Prod_ID", con);
cmd.Parameters.Add("#Prod_ID", SqlDbType.Varchar, 6).Value = "P" + Request.QueryString["id"].ToString;
After create and initialize SqlCommand, then you pass it into SqlDataAdpater as below
SqlDataAdapter da = new SqlDataAdapter(cmd);
Additional recommendation:
Use using block for your SqlConnection, SqlCommand and SqlDataAdapter as these (implemented with IDisposable interface) will automatically dispose the resources once the process is ended or exception is triggered.
DataSet ds = new DataSet();
using (SqlConnection conn = new SqlConnection(Global.cs))
{
using (SqlCommand cmd = new SqlCommand("select * from Product2 where prod_id = #Prod_ID", con))
{
cmd.Parameters.Add("#Prod_ID", SqlDbType.Varchar, 6).Value = "P" + Request.QueryString["id"].ToString;
using (SqlDataAdapter da = new SqlDataAdapter(cmd))
{
da.Fill(ds);
}
}
}
Updated answer with credited to #Tim Schmelter's suggestion
For Using declarations in C#8.0, you are not required to add scope for the using block.
A using declaration is a variable declaration preceded by the using keyword. It tells the compiler that the variable being declared should be disposed at the end of the enclosing scope.
DataSet ds = new DataSet();
using SqlConnection conn = new SqlConnection(Global.cs);
using SqlCommand cmd = new SqlCommand("select * from Product2 where prod_id = #Prod_ID", con);
cmd.Parameters.Add("#Prod_ID", SqlDbType.Varchar, 6).Value = "P" + Request.QueryString["id"].ToString;
using SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
I want to show my datatable value into text box with including headers
I tried something like this not sure its correct or not ?
private void Button16_Click(object sender, EventArgs e)
{
textBox5.Text = string.Empty;
if (checkedListBox1.CheckedItems.Count > 0)
{
string strSQLConn = "Server =" + textBox1.Text + "; Initial Catalog =" + textBox2.Text + "; User ID =" + textBox3.Text + "; Password = " + textBox4.Text + ";";
SqlConnection SQLConn = new SqlConnection(strSQLConn);
SQLConn.Open();
foreach (var item in checkedListBox1.CheckedItems)
{
DataRowView row = item as DataRowView;
SqlCommand SQLCmd = new SqlCommand("select TABLE_NAME, COLUMN_NAME, DATA_TYPE, CHARACTER_MAXIMUM_LENGTH, IS_NULLABLE from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = '" + row["Table_Name"] + "' ", SQLConn);
SQLCmd.CommandType = CommandType.Text;
SqlDataAdapter Da = new SqlDataAdapter(SQLCmd);
DataTable dt = new DataTable();
Da.Fill(dt);
if (dt.Rows.Count > 0)
{
textBox5.Text = dt.Rows[0]["TABLE_NAME"].ToString();
textBox5.Text = dt.Rows[0]["COLUMN_NAME"].ToString();
textBox5.Text = dt.Rows[0]["DATA_TYPE"].ToString();
textBox5.Text = dt.Rows[0]["CHARACTER_MAXIMUM_LENGTH"].ToString();
textBox5.Text = dt.Rows[0]["IS_NULLABLE"].ToString();
}
}
}
I believe you are trying to append instead of overriding the text. Therefore,
textBox5.Text = dt.Rows[0]["TABLE_NAME"].ToString() + ", ";
textBox5.Text += dt.Rows[0]["COLUMN_NAME"].ToString()+ ", ";
textBox5.Text += dt.Rows[0]["DATA_TYPE"].ToString()+ ", ";
textBox5.Text += dt.Rows[0]["CHARACTER_MAXIMUM_LENGTH"].ToString()+ ", ";
textBox5.Text += dt.Rows[0]["IS_NULLABLE"].ToString();
To go through all rows
for (int i = 0; i < dt.Rows.Count; i++)
{
textBox5.Text = dt.Rows[i]["TABLE_NAME"].ToString() + ", ";
textBox5.Text += dt.Rows[i]["COLUMN_NAME"].ToString()+ ", ";
textBox5.Text += dt.Rows[i]["DATA_TYPE"].ToString()+ ", ";
textBox5.Text += dt.Rows[i]["CHARACTER_MAXIMUM_LENGTH"].ToString()+ ", ";
textBox5.Text += dt.Rows[i]["IS_NULLABLE"].ToString();
}
Moreover, I suggest to scope your connection, command and adapter in using(so system can close/dispose them automatically) and use
SqlParameter instead of string concatenation(to prevent potential SQL injection)
using (SqlConnection SQLConn = new SqlConnection(strSQLConn))
{
SQLConn.Open();
foreach (var item in checkedListBox1.CheckedItems)
{
DataRowView row = item as DataRowView;
using (SqlCommand SQLCmd = new SqlCommand("select TABLE_NAME, COLUMN_NAME, DATA_TYPE, CHARACTER_MAXIMUM_LENGTH, IS_NULLABLE from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = #tableName ", SQLConn))
{
SQLCmd.Parameters.AddWithValue("tableName", row["Table_Name"]);
using (SqlDataAdapter Da = new SqlDataAdapter(SQLCmd))
{
DataTable dt = new DataTable();
Da.Fill(dt);
// rest of the code
}
}
}
}
You can retrieve columns from DataTable.Columns and if you too want to attach to the TextBox then sample as below
textBox5.Text += string.Join(",", dt.Columns.OfType<DataColumn>().Select(col => col.ColumnName));

I am new to C# and I want to do this ASAP as I've had this problem since past week. I have tried a few approaches and not yet gotten the correct output. Here is my code:
private void btnDelete_Click(object sender, EventArgs e)
{
try
{
String itemcode = tbItemCode.Text.ToString();
String shade = tbShade.Text.ToString();
String rollnumber = tbRollNumber.Text.ToString();

String deletequery = "DELETE FROM TabRoll WHERE (ItemCode = '" + itemcode + "') AND (Shade = '" + shade + "') AND (RollNumber = '" + rollnumber + "')";
//String deletequery = "SELECT * FROM TabRoll";
//code by query builder ----> DELETE FROM TabRoll WHERE (ItemCode = '" + itemcode + "') AND (Shade = '" + shade + "') AND (RollNumber = '" + length + "');
conn.Open();
OleDbDataAdapter da = new OleDbDataAdapter(deletequery, conn);
OleDbCommandBuilder cb = new OleDbCommandBuilder(da);
DataTable dt = new DataTable();
da.Fill(dt);
BindingSource bSource = new BindingSource();
bSource.DataSource = dt;
dataGridView1.EndEdit();
bSource.EndEdit();
da.Update(dt);
dataGridView1.DataSource = bSource;
conn.Close();
MessageBox.Show("Data deleted");
}
catch (Exception exceptionObj)
{
MessageBox.Show(exceptionObj.Message.ToString());
}
}
Why doesn't the DataGrid does not update with the new record.
I'm trying to export a SQL-Server query to an XML file now and I want to import that file to Access. I don't understand how to do this.
Here is the code I use to generate the XML:
protected void Button1_Click(object sender, EventArgs e) {
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlSconn"].ConnectionString);
con.Open();
string strSQL = "select * from dbo.table_"+test.Text.ToString()+"";
SqlDataAdapter dt = new SqlDataAdapter(strSQL, con);
DataSet ds = new DataSet();
dt.Fill(ds, "" + test.Text.ToString() + "");
ds.WriteXml(Server.MapPath("temp.xml"));
}
This may be a start.
static void SaveToMDB(DataSet ds, string strMDBFile)
{
OleDbConnection cAccess = new OleDbConnection(
"Provider=Microsoft.Jet.OLEDB.4.0;Data source=" + strMDBFile);
cAccess.Open();
foreach (DataTable oTable in ds.Tables)
{
OleDbCommand oCommand = new OleDbCommand(
"DROP TABLE [" + oTable.TableName + "]", cAccess);
try
{
oCommand.ExecuteNonQuery();
}
catch (Exception) { }
string strCreateColumns = "";
string strColumnList = "";
string strQuestionList = "";
foreach (DataColumn oColumn in oTable.Columns)
{
strCreateColumns += "[" + oColumn.ColumnName + "] VarChar(255), ";
strColumnList += "[" + oColumn.ColumnName + "],";
strQuestionList += "?,";
}
strCreateColumns = strCreateColumns.Remove(strCreateColumns.Length - 2);
strColumnList = strColumnList.Remove(strColumnList.Length - 1);
strQuestionList = strQuestionList.Remove(strQuestionList.Length - 1);
oCommand = new OleDbCommand("CREATE TABLE [" + oTable.TableName
+ "] (" + strCreateColumns + ")", cAccess);
oCommand.ExecuteNonQuery();
OleDbDataAdapter da = new OleDbDataAdapter(
"SELECT * FROM [" + oTable.TableName + "]", cAccess);
da.MissingSchemaAction = MissingSchemaAction.Add;
da.FillLoadOption = LoadOption.OverwriteChanges;
da.InsertCommand = new OleDbCommand(

foreach (DataColumn oColumn in oTable.Columns)
{

}
