Same code for MSACCESS and SQLSERVER but giving error

Question

Hi, as you see I have two pieces of codes transfering datas Table1 to Table2.

 

1) The first piece is transfering datas using MSAccess’s Table. It doing well the job.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string myConnectionString;
myConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Copy_table_to_table\WindowsFormsApplication1\App_Datas\test.mdb;Persist Security Info=False";
using (var con = new OleDbConnection())
{
con.ConnectionString = myConnectionString;
con.Open();
using (var cmd = new OleDbCommand())
{
cmd.Connection = con;
cmd.CommandType = System.Data.CommandType.Text;
cmd.CommandText = @"INSERT INTO test2 IN 'C:\Copy_table_to_table\WindowsFormsApplication1\App_Datas\test.mdb' " + @"SELECT A,B,C FROM test1";
cmd.ExecuteNonQuery();
}
con.Close();
}
Console.WriteLine("Done.");
}
}
}

2) The Segond piece is transfering from Table1 to Table2 uing SQLSERVER’s Table. Unfortunatly, its stucking giving this error message: Incorrect syntax near the keyword 'IN'

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data;
using System.Data.SqlClient;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
SqlConnection conn = new SqlConnection("Data Source = (LocalDB)\\MSSQLLocalDB; AttachDbFilename=C:\\Copy_table_to_table\\WindowsFormsApplication1\\test.mdf;Integrated Security = True;Integrated Security = True");
SqlCommand comm;
SqlDataAdapter da;
string connstr = @"Data Source = (LocalDB)\\MSSQLLocalDB; AttachDbFilename=C:\\Copy_table_to_table\\WindowsFormsApplication1\\test.mdf;Integrated Security = True;Integrated Security = True";
private void button1_Click(object sender, EventArgs e)
{
string myConnectionString;
myConnectionString = "Data Source = (LocalDB)\\MSSQLLocalDB; AttachDbFilename = C:\\Copy_table_to_table\\WindowsFormsApplication1\\test.mdf; Integrated Security = True; Integrated Security = True";
{
conn = new SqlConnection("Data Source = (LocalDB)\\MSSQLLocalDB; AttachDbFilename = C:\\Copy_table_to_table\\WindowsFormsApplication1\\test.mdf; Integrated Security = True; Integrated Security = True");
if (conn.State != ConnectionState.Open)
conn.Open();
using (var cmd = new SqlCommand())
{
cmd.Connection = conn;
cmd.CommandType = System.Data.CommandType.Text;
cmd.CommandText = @"INSERT INTO test2 IN 'C:\Copy_table_to_table\WindowsFormsApplication1\test.mdf' " + @"SELECT A,B,C FROM test1";
cmd.ExecuteNonQuery();
}
}
Console.WriteLine("Done.");
conn.Close();
}
}
}
