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?
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"]);
}
}
}

使用短小精悍的。所以我加了这个，希望大家有所帮助。
public void Insert(ProductName obj)
{
SqlConnection connection = new SqlConnection(Connection.GetConnectionString());
connection.Open();
connection.Execute("ProductName_sp", new
{ @Name = obj.Name, @Code = obj.Code, @CategoryId = obj.CategoryId, @CompanyId = obj.CompanyId, @ReorderLebel = obj.ReorderLebel, @logo = obj.logo,@Status=obj.Status, @ProductPrice = obj.ProductPrice,
@SellingPrice = obj.SellingPrice, @VatPercent = obj.VatPercent, @Description=obj.Description, @ColourId = obj.ColourId, @SizeId = obj.SizeId,
@BrandId = obj.BrandId, @DisCountPercent = obj.DisCountPercent, @CreateById =obj.CreateById, @StatementType = "Create" }, commandType: CommandType.StoredProcedure);
connection.Close();
}
这是一个存储过程的示例，它返回一个值并在c#中执行
CREATE PROCEDURE [dbo].[InsertPerson]
-- Add the parameters for the stored procedure here
@FirstName nvarchar(50),@LastName nvarchar(50),
@PersonID int output
AS
BEGIN
insert [dbo].[Person](LastName,FirstName) Values(@LastName,@FirstName)
set @PersonID=SCOPE_IDENTITY()
END
Go
--------------
// Using stored procedure in adapter to insert new rows and update the identity value.
static void InsertPersonInAdapter(String connectionString, String firstName, String lastName) {
String commandText = "dbo.InsertPerson";
using (SqlConnection conn = new SqlConnection(connectionString)) {
SqlDataAdapter mySchool = new SqlDataAdapter("Select PersonID,FirstName,LastName from [dbo].[Person]", conn);
mySchool.InsertCommand = new SqlCommand(commandText, conn);
mySchool.InsertCommand.CommandType = CommandType.StoredProcedure;
mySchool.InsertCommand.Parameters.Add(
new SqlParameter("@FirstName", SqlDbType.NVarChar, 50, "FirstName"));
mySchool.InsertCommand.Parameters.Add(
new SqlParameter("@LastName", SqlDbType.NVarChar, 50, "LastName"));
SqlParameter personId = mySchool.InsertCommand.Parameters.Add(new SqlParameter("@PersonID", SqlDbType.Int, 0, "PersonID"));
personId.Direction = ParameterDirection.Output;
DataTable persons = new DataTable();
mySchool.Fill(persons);
DataRow newPerson = persons.NewRow();
newPerson["FirstName"] = firstName;
newPerson["LastName"] = lastName;
persons.Rows.Add(newPerson);
mySchool.Update(persons);
Console.WriteLine("Show all persons:");
ShowDataTable(persons, 14);
