既然要学习NHibernate，那知道如何执行存储过程自然是必不可少的，网上有很多资料是用新建映射文件的方式在NHibernate中执行存储过程，我个人觉得这真的不太好，反复琢磨后搞出了下面的这种方式，希望对大家有帮助。
一、NHibernate执行insert存储过程（无返回值）
CREATE PROCEDURE [dbo].[proc_AddSysDict]
@Id uniqueidentifier,
@DictCode nvarchar(50),
@DictName nvarchar(50),
@ParentCode uniqueidentifier
AS
BEGIN
SET NOCOUNT ON;
-- Insert statements for procedure here
insert into Sys_Dict(Id, DictCode, DictName, ParentCode, Remarks,CreateTime) values(@Id,@DictCode,@DictName,@ParentCode,'proc备注',GETDATE())
ENDpublic ActionResult Index()
{
#region 执行存储过程
using (IDbConnection connection = new NHibernateHelper().OpenSession().Connection)
{
IDbTransaction transaction = connection.BeginTransaction();
using (IDbCommand command = connection.CreateCommand())
{
try
{
command.Transaction = transaction;
#region 执行Insert操作，无返回值
command.CommandText = "proc_AddSysDict";
command.CommandType = CommandType.StoredProcedure;
IDbDataParameter pp_Id = command.CreateParameter();
pp_Id.DbType = DbType.Guid;
pp_Id.ParameterName = "Id";
pp_Id.Value = Guid.NewGuid();
pp_Id.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_Id);
IDbDataParameter pp_DictCode = command.CreateParameter();
pp_DictCode.DbType = DbType.String;
pp_DictCode.ParameterName = "DictCode";
pp_DictCode.Value = "90002";
pp_DictCode.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_DictCode);
IDbDataParameter pp_DictName = command.CreateParameter();
pp_DictName.DbType = DbType.String;
pp_DictName.ParameterName = "DictName";
pp_DictName.Value = "proc车辆型号";
pp_DictName.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_DictName);
IDbDataParameter pp_ParentCode = command.CreateParameter();
pp_ParentCode.DbType = DbType.String;
pp_ParentCode.ParameterName = "ParentCode";
pp_ParentCode.Value = "cbb2cdb6-1ebe-44b2-970f-a95a04fc169b";
pp_ParentCode.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_ParentCode);
command.ExecuteNonQuery();
#endregion
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
}
}
}
#endregion
return View();
}二、NHibernate执行insert存储过程（返回主键）
CREATE PROCEDURE [dbo].[proc_AddSysDict02]
@DictCode nvarchar(50),
@DictName nvarchar(50),
@ParentCode uniqueidentifier
AS
BEGIN
SET NOCOUNT ON;
declare @Id uniqueidentifier;
set @Id = newid();
-- Insert statements for procedure here
insert into Sys_Dict(Id, DictCode, DictName, ParentCode, Remarks,CreateTime) values(@Id,@DictCode,@DictName,@ParentCode,'proc备注',GETDATE());
select @Id
ENDpublic ActionResult Index()
{
#region 执行存储过程
using (IDbConnection connection = new NHibernateHelper().OpenSession().Connection)
{
IDbTransaction transaction = connection.BeginTransaction();
using (IDbCommand command = connection.CreateCommand())
{
try
{
command.Transaction = transaction;
#region 执行Insert操作，返回主键
command.CommandText = "proc_AddSysDict02";
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Clear();
pp_DictCode.DbType = DbType.String;
pp_DictCode.ParameterName = "DictCode";
pp_DictCode.Value = "90003";
pp_DictCode.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_DictCode);
pp_DictName.DbType = DbType.String;
pp_DictName.ParameterName = "DictName";
pp_DictName.Value = "proc车辆型号";
pp_DictName.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_DictName);
pp_ParentCode.DbType = DbType.String;
pp_ParentCode.ParameterName = "ParentCode";
pp_ParentCode.Value = "cbb2cdb6-1ebe-44b2-970f-a95a04fc169b";
pp_ParentCode.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_ParentCode);
string result = command.ExecuteScalar().ToString();
#endregion
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
}
}
}
#endregion
return View();
}三、NHibernate执行delete存储过程
CREATE PROCEDURE [dbo].[proc_RemoveSysDict]
@DictName nvarchar(50),
@ParentCode uniqueidentifier
AS
BEGIN
-- 若设置了set nocount on则无论删除了多少行都返回-1
-- SET NOCOUNT ON;
-- Insert statements for procedure here
delete from Sys_Dict where ParentCode=@ParentCode and DictName like '%'+@DictName+'%';
ENDpublic ActionResult Index()
{
#region 执行存储过程
using (IDbConnection connection = new NHibernateHelper().OpenSession().Connection)
{
IDbTransaction transaction = connection.BeginTransaction();
using (IDbCommand command = connection.CreateCommand())
{
try
{
command.Transaction = transaction;
#region 执行Delete操作
command.CommandText = "proc_RemoveSysDict";
command.CommandType = CommandType.StoredProcedure;
IDbDataParameter pp_DictName = command.CreateParameter();
pp_DictName.DbType = DbType.String;
pp_DictName.ParameterName = "DictName";
pp_DictName.Value = "部门";
pp_DictName.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_DictName);
IDbDataParameter pp_ParentCode = command.CreateParameter();
pp_ParentCode.DbType = DbType.String;
pp_ParentCode.ParameterName = "ParentCode";
pp_ParentCode.Value = "cbb2cdb6-1ebe-44b2-970f-a95a04fc169b";
pp_ParentCode.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_ParentCode);
//存储过程中不要设置SET NOCOUNT ON;，否则无论删除了多少行返回值都是-1
int count = command.ExecuteNonQuery();
#endregion
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
}
}
}
#endregion
return View();
}四、NHibernate执行update存储过程
CREATE PROCEDURE [dbo].[proc_UpdateSysDict]
-- Add the parameters for the stored procedure here
@OldParentCode uniqueidentifier,
@NewParentCode uniqueidentifier
AS
BEGIN
-- 若设置了set nocount on则无论删除了多少行都返回-1
-- SET NOCOUNT ON;
-- Insert statements for procedure here
update Sys_Dict set ParentCode=@NewParentCode where ParentCode=@OldParentCode
ENDpublic ActionResult Index()
{
#region 执行存储过程
using (IDbConnection connection = new NHibernateHelper().OpenSession().Connection)
{
IDbTransaction transaction = connection.BeginTransaction();
using (IDbCommand command = connection.CreateCommand())
{
try
{
command.Transaction = transaction;
#region 执行Update操作
command.CommandText = "proc_UpdateSysDict";
command.CommandType = CommandType.StoredProcedure;
IDbDataParameter pp_OldParentCode = command.CreateParameter();
pp_OldParentCode.DbType = DbType.String;
pp_OldParentCode.ParameterName = "OldParentCode";
pp_OldParentCode.Value = "781782ad-0fe1-4cd3-961c-aaaaaaaaaaaa";
pp_OldParentCode.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_OldParentCode);
IDbDataParameter pp_NewParentCode = command.CreateParameter();
pp_NewParentCode.DbType = DbType.String;
pp_NewParentCode.ParameterName = "NewParentCode";
pp_NewParentCode.Value = "781782ad-0fe1-4cd3-961c-bbbbbbbbbbbb";
pp_NewParentCode.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_NewParentCode);
//存储过程中不要设置SET NOCOUNT ON;，否则无论修改了多少行返回值都是-1
int count = command.ExecuteNonQuery();
#endregion
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
}
}
}
#endregion
return View();
}五、NHibernate执行select存储过程
CREATE PROCEDURE [dbo].[proc_GetSysDict]
@ParentCode UNIQUEIDENTIFIER,
@DictName NVARCHAR(50)
AS
BEGIN
SET NOCOUNT ON;
-- Insert statements for procedure here
select Id, DictCode, DictName, ParentCode, Remarks, CreateTime from Sys_Dict where ParentCode=@ParentCode and DictName like '%'+@DictName+'%';
select @@ROWCOUNT as TotalRowCount
ENDpublic ActionResult Index()
{
#region 执行存储过程
using (IDbConnection connection = new NHibernateHelper().OpenSession().Connection)
{
IDbTransaction transaction = connection.BeginTransaction();
using (IDbCommand command = connection.CreateCommand())
{
try
{
command.Transaction = transaction;
#region 执行Select操作
command.CommandText = "proc_GetSysDict";
command.CommandType = CommandType.StoredProcedure;
IDbDataParameter pp_DictName = command.CreateParameter();
pp_DictName.DbType = DbType.String;
pp_DictName.ParameterName = "DictName";
pp_DictName.Value = "部门";
pp_DictName.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_DictName);
IDbDataParameter pp_ParentCode = command.CreateParameter();
pp_ParentCode.DbType = DbType.String;
pp_ParentCode.ParameterName = "ParentCode";
pp_ParentCode.Value = "781782ad-0fe1-4cd3-961c-bbbbbbbbbbbb";
pp_ParentCode.Direction = ParameterDirection.Input;
command.Parameters.Add(pp_ParentCode);
SqlDataAdapter adapter = new SqlDataAdapter((SqlCommand)command);
DataSet ds = new DataSet();
adapter.Fill(ds);
DataTable list = ds.Tables[0];
DataTable count = ds.Tables[1];
#endregion
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
}
}
}
#endregion
return View();
}
