增加SQL命令的命令超时

Question

我有一点问题,希望有人可以给我一些建议.我正在运行一个SQL命令,但它似乎需要这个命令大约2分钟才能返回数据,因为有很多数据.但是默认连接时间是30秒,如何增加它,并将其应用于此命令？

public static DataTable runtotals(string AssetNumberV, string AssetNumber1V)
{
    DataTable dtGetruntotals;

    try
    {
        dtGetruntotals = new DataTable("Getruntotals");

        //SqlParameter AssetNumber = new SqlParameter("@AssetNumber", SqlDbType.VarChar, 6);
        //AssetNumber.Value = AssetNumberV; 

        SqlParameter AssetNumber = new SqlParameter("@AssetNumber", SqlDbType.VarChar, 10);
        AssetNumber.Value = AssetNumberV;

        SqlParameter AssetNumber1 = new SqlParameter("@AssetNumber1", SqlDbType.VarChar, 10);
        AssetNumber1.Value = AssetNumber1V;

        SqlCommand scGetruntotals = new SqlCommand("EXEC spRunTotals @AssetNumber,@AssetNumber1 ", DataAccess.AssetConnection); 
        // scGetruntotals.Parameters.Add(AssetNumber);
        scGetruntotals.Parameters.Add(AssetNumber);
        scGetruntotals.Parameters.Add(AssetNumber1);

        SqlDataAdapter sdaGetruntotals = new SqlDataAdapter();
        sdaGetruntotals.SelectCommand = scGetruntotals;
        sdaGetruntotals.Fill(dtGetruntotals);

        return dtGetruntotals;
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error Retriving totals Details: Processed with this error:" + ex.Message);
        return null;
    }
}

Answer 1

由于有大量数据,它需要大约2分钟才能返回数据

糟糕的设计.考虑在这里使用分页.

默认连接时间是30秒,我该如何增加它

当您面临命令的暂停时,因此您需要增加sql命令的时间.您可以在命令中指定它

// Setting command timeout to 2 minutes
scGetruntotals.CommandTimeout = 120;

Answer 2

添加你的超时SqlCommand.请注意时间是秒.

// Setting command timeout to 1 second
scGetruntotals.CommandTimeout = 1;
