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: …

我收到了一个错误

关键字WHERE附近的语法不正确

使用以下SQL语句:

SqlCommand scInsertCostSpilt = new SqlCommand("INSERT INTO [ASSETS_CC] ([DEPT], [CC], [PER_CENT]) WHERE [ASSET_NO] = @AssetNumber)" +
"Values (@AssetNumber, @Dept, @CC, @PerCent)" , DataAccess.AssetConnection);

怎么了？

有人可以告诉我为什么我得到以下错误,当我通过我的代码,我不确定它是否与我的SQL语句的问题,因为这似乎是好的,但我在下面添加它,以便我可以得到一个第二个意见

"从字符串转换日期/时间时转换失败"

public static int GetConveyorProductionCount(string machineNameV, string StartTimeV, string EndTimeV)
    {

        try
        {
            int count;

            SqlParameter param01 = new SqlParameter("@param01", SqlDbType.VarChar, 5);
            param01.Value = machineNameV;

            SqlParameter param02 = new SqlParameter("@param02", SqlDbType.VarChar, 5);
            param02.Value = StartTimeV;

            SqlParameter param03 = new SqlParameter("@param03", SqlDbType.VarChar, 5);
            param03.Value = EndTimeV;

            SqlCommand getConveyorProductionSC = new SqlCommand("SELECT cast([" + machineNameV + "] as int) FROM VWCONVEYORPRODUCTION WHERE([DA_TE] BETWEEN @param02 AND @param03)", myConnection);

            getConveyorProductionSC.Parameters.Add(param01);
            getConveyorProductionSC.Parameters.Add(param02);
            getConveyorProductionSC.Parameters.Add(param03);

            myConnection.Open();
            object result = getConveyorProductionSC.ExecuteScalar();
            myConnection.Close();

            if (result == DBNull.Value)
            { …

我在我的代码中使用以下语句得到语法错误,我已经通过它,除非我错过了一些东西,否则我看不出任何错误:
