在asp.net中执行存储过程（转）

摘自：http://www.cnblogs.com/smhy8187/articles/677742.html

声明:本例用的数据库是系统提供的pubs数据库,表是是employee,编程语言用C#

1.执行不带参数的存储过程存储过程：

create proc example1
as
begin
select top 6 emp_id,fname,lname
from employee
end

执行代码：

SqlConnection Conn = new SqlConnection("server=.;database=pubs;uid=sa;pwd=");
Conn.Open();
SqlCommand cmd = new SqlCommand("example1", Conn);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataReader dr = cmd.ExecuteReader();

//输出执行结果
string table = "<table border='1'><tr>";
int field = dr.FieldCount;

for (int i = 0; i <= field - 1; i++)
{
table += "<TD>" + dr.GetName(i) + "</td>";
}

table += "</tr>";
while (dr.Read())
{
table += "<tr>";
for (int i = 0; i <= field - 1; i++)
{
table += "<TD>" + dr.GetValue(i) + "</td>";
}
table += "</tr>";
}
table += "</table>";
Conn.Close();
Response.Write(table);

2.执行带普通参数的存储过程
    存储过程：

create proc example2

@empid varchar(9)

as

begin

select emp_id,fname,lname from employee

where emp_id=@empid

end

执行代码：

SqlConnection Conn = new SqlConnection("server=.;database=pubs;uid=sa;pwd=");Conn.Open(); SqlCommand cmd = new SqlCommand("example2", Conn); cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add("@empid", SqlDbType.VarChar, 9);

cmd.Parameters["@empid"].Value = "PMA42628M";

SqlDataReader dr = cmd.ExecuteReader();

//显示执行结果

string table = "<table border='1'><tr>";
int field = dr.FieldCount;

for (int i = 0; i <= field - 1; i++)
{
table += "<TD>" + dr.GetName(i) + "</td>";
}

table += "</tr>";
while (dr.Read())
{
table += "<tr>";
for (int i = 0; i <= field - 1; i++)
{
table += "<TD>" + dr.GetValue(i) + "</td>";
}
table += "</tr>";
}
table += "</table>";
Conn.Close();
Response.Write(table);

3.执行带output型参数的存储过程
存储过程：

 create proc example3 @Count int output as begin select @Count=(select count(*) from employee) end

执行代码：

SqlConnection Conn = new SqlConnection("server=.;database=pubs;uid=sa;pwd=");

Conn.Open();

SqlCommand cmd = new SqlCommand("example3", Conn); cmd.CommandType =andType.StoredProcedure;

cmd.Parameters.Add("@Count", SqlDbType.VarChar, 9);

cmd.Parameters["@count"].Direction = ParameterDirection.Output;

SqlDataReader dr = cmd.ExecuteReader();

Conn.Close();

int c =Convert.ToInt32(cmd.Parameters["@count"].Value); Response.Write(c.ToString());

4.执行用return返回的存储过程
存储过程：

create proc example4as

Begin

declare @Count int

select @Count=(select count(*) from employee)

return @Countend

执行代码：

 
SqlConnection Conn = new SqlConnection("server=.;database=pubs;uid=sa;pwd=");

Conn.Open();

SqlCommand cmd = new SqlCommand("example4", Conn); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add("Count", SqlDbType.VarChar, 9); cmd.Parameters["count"].Direction = ParameterDirection.ReturnValue;

SqlDataReader dr = cmd.ExecuteReader();

Conn.Close();

int c =Convert.ToInt32(cmd.Parameters["count"].Value); Response.Write(c.ToString());
