从C#/ASp.NET调用SQL过程
我一直在为一个雇主的网站上工作，该网站包含数据库信息，允许用户随意编辑信息。我收到的一个请求是添加一个名为Deactivate的按钮，onclick应该将标记“X”添加到名为“Inactive”的列中，说明该行实际上对任何选中复选框的行都是非活动的。复选框已添加到GridView中 我曾尝试通过SQL Server Management Studio添加存储过程，但是按照Microsoft文档中列出的教程，在右键单击存储过程文件夹时，我没有添加/创建新存储过程的选项 我已经在互联网上搜索了好几天，我不知道我是否没有找到正确的答案，或者我只是没有正确地理解它们 SQL停用命令伪代码从C#/ASp.NET调用SQL过程,c#,html,asp.net,sql-server,C#,Html,Asp.net,Sql Server,我一直在为一个雇主的网站上工作，该网站包含数据库信息，允许用户随意编辑信息。我收到的一个请求是添加一个名为Deactivate的按钮，onclick应该将标记“X”添加到名为“Inactive”的列中，说明该行实际上对任何选中复选框的行都是非活动的。复选框已添加到GridView中 我曾尝试通过SQL Server Management Studio添加存储过程，但是按照Microsoft文档中列出的教程，在右键单击存储过程文件夹时，我没有添加/创建新存储过程的选项 我已经在互联网上搜索了好几天

您被前端代码和SQL代码弄糊涂了 您的SQL伪代码应该类似于：
updateproducts SET Active=0，其中ProductID=@ProductIDActiveProductIDGridViewTemplateFieldItemTemplate foreach (GridViewRow rw in GridView.Rows) //Loop through all the rows in the GridView
{
if(rw.RowType == DataControlRowType.DataRow) //Checks if current row in the loop is a valid DataRow, not a Header or Footer row (which doesn't include the CheckBox and the data)
{
CheckBox cbProd = (CheckBox)rw.Cells[0].FindControl("chkRow"); //Finds the checkbox in the first column
HiddenField hfProd = (HiddenField)rw.Cells[0].FindControl("hfProdID"); //Finds the HiddenField in the first column where ProductID is stored
if(cbProd.Checked == true) //Checks if the current checkbox is selected, if yes, execute the UPDATE query by passing the Product ID as the parameter.
{
string sqlConnStr = ("put actual connection string here");
string sqlCmdStr = ("UPDATE Products SET Active = 0 WHERE ProductID = @ProductID"); //UPDATE query
using(SqlConnection sqlConn = new SqlConnection(sqlConnStr))
{
using(SqlCommand sqlCmd = new SqlCommand(sqlCmdStr, sqlConn))
{
sqlConn.Open();
sqlCmd.Parameters.Clear();
sqlCmd.Parameters.AddWithValue("ProductID", hfProd.Value); //Product ID saved in HiddenField
sqlCmd.ExecuteNonQuery();
sqlConn.Close();
}
}
}
}
}
public static DataTable GetData()
{
String callProcedure = "exec my_proc";
DataTable dt = new DataTable();
using (SqlConnection con = new SqlConnection("connection string here!"))
{
con.Open();
using (SqlCommand cmd = con.CreateCommand())
{
cmd.CommandText = callProcedure;
cmd.CommandType = CommandType.StoredProcedure;
using (SqlDataAdapter adp = new SqlDataAdapter(cmd))
{
adp.Fill(dt);
return dt;
}
}

你什么意思？你想知道如何创建存储过程吗？好吧，我只是想在我的网站上请求帮助运行SQL代码，但是如果我确实需要通过创建存储过程来解决这个问题，那么任何帮助都将不胜感激。正如你所知，我对C#和SQL相当陌生，因此如果我感到沮丧，我向你道歉。在你说的点击按钮事件中，我该如何准确地添加它。我是在C#中添加程序/函数还是将其添加到ASP.NET？从设计视图中，您需要双击按钮，它会将您重定向到代码隐藏，将创建一个
ASPda_单击ConnectionString=“”
