我有2個表,即配置文件和信息。更新多個表
我的表是這樣的:
PROFILE
| p_Id | FirstName | LastName |
| 1 | Jack | Cole |
| 2 | Cynthia | Cole |
| 3 | Robert | Cole |
信息
| I_Id | childsID | fathersID | mothersID | Country |
| 1 | 1 | 3 | 2 | USA |
我在文本框中顯示它們檢索從這些表中的值,我選擇的查詢是:
SELECT p.p_Id, p.FirstName, p.LastName, i.*,
(SELECT pp.FirstName+' '+pp.LastName FROM Profile pp WHERE pp.p_Id=i.childsID) AS child,
(SELECT pp.FirstName+' '+pp.LastName FROM Profile pp WHERE pp.p_Id=i.fathersID) AS father,
(SELECT pp.FirstName+' '+pp.LastName FROM Profile pp WHERE pp.p_Id=i.mothersID) AS mother
FROM Info i
INNER JOIN Profile p
ON p.p_Id=i.childsID
與選擇沒有問題,我能夠在文本框顯示的值,但問題是,我不能更新它們,到目前爲止我這個嘗試:
using (SqlCommand cmd = con.CreateCommand())
{
con.Open();
cmd.CommandText = @"UPDATE Profile SET [email protected], [email protected] WHERE p_Id = @pid;
UPDATE Info SET [email protected], [email protected], [email protected], [email protected] WHERE I_Id = @iid;";
cmd.Parameters.Add(new SqlParameter("@fname", txtfname.Text));
cmd.Parameters.Add(new SqlParameter("@lname", txtlname.Text));
cmd.Parameters.Add(new SqlParameter("@child", txtchild.Text));
cmd.Parameters.Add(new SqlParameter("@father", txtfather.Text));
cmd.Parameters.Add(new SqlParameter("@mother", txtmother.Text));
cmd.Parameters.Add(new SqlParameter("@country", txtcountry.Text));
cmd.Parameters.Add(new SqlParameter("@pid", txtpid.Text));
cmd.Parameters.Add(new SqlParameter("@iid", txtiid.Text));
cmd.ExecuteNonQuery();
Response.Write("alert('DATA UPDATED')");
}
我使用C#和Asp。淨 感謝提前:)天佑
我不知道,如果它是通過一個好主意將一批SQL更新語句放入單個'SqlCommand'對象的'CommandText'中,並添加批次中所有更新將使用的參數。 –
