            SqlCommand cmd = new SqlCommand(SQLQuery, conn);
            {   
                cmd.Parameters.AddWithValue("@modify_by", HttpContext.Current.User.Identity.Name);
                cmd.Parameters.AddWithValue("@modify_date", DateTime.Now.ToString(""));
                cmd.Parameters.AddWithValue("@create_by", HttpContext.Current.User.Identity.Name);
                cmd.Parameters.AddWithValue("@create_date", DateTime.Now.ToString(""));

                cmd.ExecuteNonQuery();
                
                cmd.Parameters.RemoveAt("@modify_by");
                cmd.Parameters.RemoveAt("@modify_date");
                cmd.Parameters.RemoveAt("@create_by");
                cmd.Parameters.RemoveAt("@create_date");
            }

Solution 1

Have a look at the Select * Into query.
This[^] describes this in some detail.

Here is another example - http://www.w3schools.com/sql/sql_select_into.asp[^].

Solution 3

Or if the table already exists, you can use:

SQL

INSERT INTO t_attendence
([list of fields to insert])
SELECT [list of fields to select]
FROM t_attendence_raw
WHERE [conditions to restrict the rows to insert]

yea, this is what i want to do, but in my case, there are others rows like, create_date, i wanna insert into t_attendence also. so can i use the same SQL statement?

Wendelius 28-Dec-11 3:44am

Yes you can, just add the necessary fields in both insert column list and in your select statement and it should be fine.

According to your comment for Mika I should remind you that you can use also use functions and parameters in you insert into statement in addition to source table fields :

SQL

INSERT INTO [t_attendence] (memcode, m_cardno, t_scantime, t_type, t_del, t_post, create_date, create_by, modify_date, modify_by) 
select ([t_attendence_r].[m_memcode], [t_attendence_r].[m_cardno], [t_attendence_r].[t_scantime], 'Y', 'Y', 'Y', GETDATE(), @create_by, GETDATE(), @modify_by)
from [t_attendence_r]

Hope it helps.
