我想从一个c#程序执行这个存储过程。
我在SqlServer查询窗口中编写了以下存储过程，并将其保存为
stored1:
use master
go
create procedure dbo.test as
DECLARE @command as varchar(1000), @i int
SET @i = 0
WHILE @i < 5
BEGIN
Print 'I VALUE ' +CONVERT(varchar(20),@i)
EXEC(@command)
SET @i = @i + 1
END
编辑:
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Data.SqlClient;
namespace AutomationApp
{
class Program
{
public void RunStoredProc()
{
SqlConnection conn = null;
SqlDataReader rdr = null;
Console.WriteLine("\nTop 10 Most Expensive Products:\n");
try
{
conn = new SqlConnection("Server=(local);DataBase=master;Integrated Security=SSPI");
conn.Open();
SqlCommand cmd = new SqlCommand("dbo.test", conn);
cmd.CommandType = CommandType.StoredProcedure;
rdr = cmd.ExecuteReader();
/*while (rdr.Read())
{
Console.WriteLine(
"Product: {0,-25} Price: ${1,6:####.00}",
rdr["TenMostExpensiveProducts"],
rdr["UnitPrice"]);
}*/
}
finally
{
if (conn != null)
{
conn.Close();
}
if (rdr != null)
{
rdr.Close();
}
}
}
static void Main(string[] args)
{
Console.WriteLine("Hello World");
Program p= new Program();
p.RunStoredProc();
Console.Read();
}
}
}
这将显示异常无法找到存储过程dbo.test。我需要提供路径吗?如果是，存储过程应该存储在哪个位置?
这是用于通过反射执行带参数和不带参数的存储过程的代码。
请注意，对象属性名需要与存储过程的参数匹配。
private static string ConnString = ConfigurationManager.ConnectionStrings["SqlConnection"].ConnectionString;
private SqlConnection Conn = new SqlConnection(ConnString);
public void ExecuteStoredProcedure(string procedureName)
{
SqlConnection sqlConnObj = new SqlConnection(ConnString);
SqlCommand sqlCmd = new SqlCommand(procedureName, sqlConnObj);
sqlCmd.CommandType = CommandType.StoredProcedure;
sqlConnObj.Open();
sqlCmd.ExecuteNonQuery();
sqlConnObj.Close();
}
public void ExecuteStoredProcedure(string procedureName, object model)
{
var parameters = GenerateSQLParameters(model);
SqlConnection sqlConnObj = new SqlConnection(ConnString);
SqlCommand sqlCmd = new SqlCommand(procedureName, sqlConnObj);
sqlCmd.CommandType = CommandType.StoredProcedure;
foreach (var param in parameters)
{
sqlCmd.Parameters.Add(param);
}
sqlConnObj.Open();
sqlCmd.ExecuteNonQuery();
sqlConnObj.Close();
}
private List<SqlParameter> GenerateSQLParameters(object model)
{
var paramList = new List<SqlParameter>();
Type modelType = model.GetType();
var properties = modelType.GetProperties();
foreach (var property in properties)
{
if (property.GetValue(model) == null)
{
paramList.Add(new SqlParameter(property.Name, DBNull.Value));
}
else
{
paramList.Add(new SqlParameter(property.Name, property.GetValue(model)));
}
}
return paramList;
}
using (SqlConnection conn = new SqlConnection("Server=(local);DataBase=Northwind;Integrated Security=SSPI")) {
conn.Open();
// 1. create a command object identifying the stored procedure
SqlCommand cmd = new SqlCommand("CustOrderHist", conn);
// 2. set the command object so it knows to execute a stored procedure
cmd.CommandType = CommandType.StoredProcedure;
// 3. add parameter to command, which will be passed to the stored procedure
cmd.Parameters.Add(new SqlParameter("@CustomerID", custId));
// execute the command
using (SqlDataReader rdr = cmd.ExecuteReader()) {
// iterate through results, printing each to console
while (rdr.Read())
{
Console.WriteLine("Product: {0,-35} Total: {1,2}",rdr["ProductName"],rdr["Total"]);
}
}
}
