Question

我想通过单击一个按钮将数据插入12个不同的表中。为此，我使用单个存储过程。但我的问题是当我这样做，如果有任何异常发生我的数据部分插入，但值被插入一些表，一些仍然是空的，由于这个问题发生，因为所有都相互关联。所以想知道有没有办法执行回滚，这样如果发生任何异常，整个查询将被回滚，数据不会插入任何表中。这是我目前用于插入值的代码。

public int Sp_InsertUpdateDelete(string s, SqlParameter[] spa)
{
    SqlConnection sc = new SqlConnection(cs);
    sc.Open();
    SqlCommand scm = new SqlCommand(s, sc);
    scm.CommandType = CommandType.StoredProcedure;
    foreach (SqlParameter sql in spa)
    {
        scm.Parameters.Add(sql);
    }
    int k = scm.ExecuteNonQuery();
    sc.Close();
    return k;

}



protected void btnHostingSubmit_Click(object sender, EventArgs e)
{
    string select = "select * from tbl_Hosting where Customer_Id='" + ddlCustomerName.SelectedValue + "'";
    DataSet s = gs.select(select);
    if (s.Tables[0].Rows.Count > 0)
    {
        Response.Write("<script>alert('Customer Already Exist');</script>");
    }

Answer 1

using(SqlConnection conn = new SqlConnection())
{
   try
   {
    conn.Open();

    SqlTransaction tran = conn.BeginTransaction("Transaction1");
Cmd = new SqlCommand(sQuery, Conn);
Cmd.Transaction = tran;
    //Your Code

    tran.Commit(); //both are successful
   }
   catch(Exception ex)
   {
      //if error occurred, reverse all actions. By this, your data consistent and correct
      tran.Rollback();
   }
}

Answer 2

您需要修改存储过程并使用此功能进行交易。

这样的事情：

＆＃13;

DECLARE @TranName VARCHAR(20);
SELECT @TranName = 'MyTransaction';

BEGIN TRANSACTION @TranName;
USE AdventureWorks2012;
DELETE FROM AdventureWorks2012.HumanResources.JobCandidate
    WHERE JobCandidateID = 13;

COMMIT TRANSACTION @TranName;
GO

＆＃13;
