1、調用沒有輸入輸出參數的存儲過程
存儲過程：
CREATE PROC GETAllBooks
AS
BEGIN
SELECT * FROM Books
END

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["StrConn"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "GetAllBooks";
cmd.Connection = conn;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
2、調用有輸入參數的存儲過程
存儲過程：
CREATE PROC ProInput
@bookname varchar(20)
AS
BEGIN
INSERT INTO Books Values('ddd777',@bookname,2)
END
調用示例：
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["StrConn"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "ProInput";
cmd.Connection = conn;
SqlParameter[] param = {
new SqlParameter("@bookname",SqlDbType.VarChar,20)
};
param[0].Value = "測試程序";
cmd.Parameters.Add(param[0]);
Response.Write(cmd.ExecuteNonQuery().ToString() + "<br/>");
3、調用有輸出參數的存儲過程
存儲過程：
CREATE PROC ProOutput
@id int output
AS
BEGIN
INSERT INTO Books Values('ddd777','output parameter',2)
set @id=@@identity
END
調用示例：
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["StrConn"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "ProOutput";
cmd.Connection = conn;
SqlParameter[] param = {
new SqlParameter("@id",SqlDbType.Int,4),
};
param[0].Direction = ParameterDirection.Output;
cmd.Parameters.Add(param[0]);
Response.Write(cmd.ExecuteNonQuery().ToString() + "<br/>");
Response.Write(param[0].Value.ToString());
4、調用有輸入輸出參數的存儲過程
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["StrConn"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "ProInputOutput";
cmd.Connection = conn;
SqlParameter[] param = {
new SqlParameter("@id",SqlDbType.Int,4),
new SqlParameter("@bookname",SqlDbType.VarChar,20)
};
param[0].Direction = ParameterDirection.Output;
param[1].Value = "測試程序";
cmd.Parameters.Add(param[0]);
cmd.Parameters.Add(param[1]);
Response.Write(cmd.ExecuteNonQuery().ToString() + "<br/>");
Response.Write(param[0].Value.ToString());
5、調用有輸入返回值參數的存儲過程
存儲過程：
Create ProcProInputReturn
@bookname varchar(20)
AS
BEGIN
INSERT INTO Books Values('www1010',@bookname,2)
return @@identity
END
調用示例：
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["StrConn"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "ProInputReturn";
cmd.Connection = conn;
SqlParameter[] param = {
new SqlParameter("@bookname",SqlDbType.VarChar,20),
new SqlParameter("@val",SqlDbType.Int,4)
};
param[0].Value = "書的名稱";
param[1].Direction = ParameterDirection.ReturnValue;
cmd.Parameters.Add(param[0]);
cmd.Parameters.Add(param[1]);
Response.Write(cmd.ExecuteNonQuery().ToString() + "<br/>");
Response.Write(param[1].Value.ToString());
6、調用有輸入輸出返回值的存儲過程
存儲過程：
create proc ProInputoutputReturn
@id int output,
@bookname varchar(20)
AS
begin
INSERT INTO Books Values('www10414',@bookname,2)
set @id=@@identity
return @@rowcount
end
調用示例：
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["StrConn"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "ProInputoutputReturn";
cmd.Connection = conn;
SqlParameter[] param = {
new SqlParameter("@id",SqlDbType.Int,4),
new SqlParameter("@bookname",SqlDbType.VarChar,20),
new SqlParameter("@val",SqlDbType.VarChar,20)
};
param[0].Direction = ParameterDirection.Output;
param[1].Value = "書的名稱";
param[2].Direction = ParameterDirection.ReturnValue;
cmd.Parameters.Add(param[0]);
cmd.Parameters.Add(param[1]);
cmd.Parameters.Add(param[2]);
Response.Write(cmd.ExecuteNonQuery().ToString() + "<br/>");
Response.Write(param[0].Value.ToString()+"<br/>");
Response.Write(param[2].Value.ToString());
7、具有返回值與記錄集的存儲過程
存儲過程：
create proc prooutputresult
@id int output,
@bookname varchar(20)
as
begin
INSERT INTO Books Values('www10414',@bookname,2)
set @id=@@identity
select * from books
return @@rowcount
end
調用示例：
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["StrConn"].ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "prooutputresult";
cmd.Connection = conn;
SqlParameter[] param = {
new SqlParameter("@id",SqlDbType.Int,4),
new SqlParameter("@bookname",SqlDbType.VarChar,20),
new SqlParameter("@val",SqlDbType.VarChar,20)
};
param[0].Direction = ParameterDirection.Output;
param[1].Value = "書的名稱";
param[2].Direction = ParameterDirection.ReturnValue;
cmd.Parameters.Add(param[0]);
cmd.Parameters.Add(param[1]);
cmd.Parameters.Add(param[2]);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
Response.Write(param[0].Value.ToString()+"<br/>");
Response.Write(param[2].Value.ToString());
8、返回多個記錄集的存儲過程
存儲過程：

conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "getmultiLog";
cmd.Connection = conn;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds.Tables[0];
GridView1.DataBind();
GridView2.DataSource = ds.Tables[1];
GridView2.DataBind();
