For the purpose of troubleshooting, I would like to return the complete SQL syntax and values to a label for either desktop or web page. I tried using sqldataadapter and  commandbuilder and still only return the sql syntax and no values.

[Query]

private void InsertTable(string lastname, string midname, string firstname)
{
      string sql = " Insert Into Table1 (col1, col2, col3) values ('" + lastname + "', '" + midname + "', '" + firstname + "')";

     SqlConnection cn = new SqlConnection(cnPath);
     SqlDataAdapter da = new SqlDataAdapter(sql, cn);
     cn.Open();
     da.SelectCommand.ExecuteNonQuery();    

     label1.Text = da.InsertCommand.CommandText;

     cn.Close();
}

[Current Return]
Insert Into Table1 (col1, col2, col3) values ('lastname', 'midname', 'firstname')

[Desired Return]
Insert Into Table1 (col1, col2, col3) values (Doe, J, Jane)

if you are using a SQL database, start a profiler, you will see all the real queries that are sent to the database.

This is the sample code I worked based on your conditions, review and do changes to relate to your database.

 
protected void BtnSubmit_Click(object sender, EventArgs e)
    {
        InsertTable("Testdata", "Testprice", "TestDesc");
    }
    private void InsertTable(string Name, string Price, string Desc)
    {
        string sql = " Insert Into tblProduct (Name,Price,Desc) values ('" + Name + "', '" + Price + "', '" + Desc + "')";

        SqlConnection cn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString2"].ConnectionString);
        SqlDataAdapter da = new SqlDataAdapter(sql, cn);
        cn.Open();
        SqlCommand com = new SqlCommand();
        com.Connection = cn;
        da.InsertCommand = com;
        da.InsertCommand.CommandText = sql;
        da.InsertCommand.CommandType = CommandType.Text;
        da.InsertCommand.ExecuteNonQuery();
        label1.Text = da.InsertCommand.CommandText;

        cn.Close();
    }

Open in new window



Web.config

<connectionStrings>
  <add name="ConnectionString2" connectionString="Data Source=SQLDB1210;Initial Catalog=SampleDB;Persist Security Info=True;User ID=sa;Password=Password;MultipleActiveResultSets=False;Packet Size=4096;Application Name=&quot;Microsoft SQL Server Management Studio&quot;"
   providerName="System.Data.SqlClient" />
 </connectionStrings>

You are using string concatenation to build your queries (almost always a bad idea), so you should see the actual values stored in the string. If you are seeing the literal value of "lastname" output to the variable holding the query, then that means the lastname actually has the value "lastname" contained within it.

Now, if you were instead using parameterized queries (the better practice) to submit queries, then you would not see the values substituted, and you would have to do something like what emoreau mentioned.

I am using parameterized queries although I didn't mention it, oops. It's a new concept and not learning how secure they really are.

I split the points because you all have excellent info. thx
