五、使用存储过程创建单号

1. 在Visual Studio 2017的“解决方案资源管理器”中，右键单击“ABP.TPLMS.Core”项目的“IRepositories”文件夹，在弹出菜单中选择“添加” > “类”。如下图。

2．在弹出对话框中选择“接口”，将接口命名为 IOutStockOrderRepository，然后选择“添加”。如下图。

3.在IOutStockOrderRepository接口定义我们需要用到的方法，代码如下。

using Abp.Dependency;
using Abp.Domain.Repositories;
using ABP.TPLMS.Entitys;
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Common;
using System.Linq;
using System.Text;
 

namespace ABP.TPLMS.IRepositories
{

    public interface IOutStockOrderRepository: IRepository<OutStockOrder, int>,
 ITransientDependency
        {
     

            DbCommand CreateCommand(string commandText, CommandType commandType
, params object[] parameters);

            /// <summary>
            /// 创建单号
            /// </summary>
            /// <param name="name">单证名称代码</param>
            /// <returns></returns>
            string GetNo(string name);

            /// <summary>
            /// 导入入库货物信息
            /// </summary>
            /// <param name="ids">导入库单的ID集合</param>
            /// <param name="no">单号</param>
            void ImportInStockOrder(string ids, string no);

    }
}

4. 在Visual Studio 2017的“解决方案资源管理器”中，右键单击“ABP.TPLMS.EntityFrameworkCore”项目的“Repositories”文件夹，在弹出菜单中选择“添加” > “类”，将类命名为 OutStockOrderRepository，并继承IOutStockOrderRepository接口。实现接口中的方法。代码如下。

using Abp.Data;
using Abp.Dependency;
using Abp.EntityFrameworkCore;
using ABP.TPLMS.Entitys;
using ABP.TPLMS.IRepositories;
using Microsoft.EntityFrameworkCore;
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Common;
using System.Data.SqlClient;
using System.Text;
 

namespace ABP.TPLMS.EntityFrameworkCore.Repositories
{

    public class OutStockOrderRepository: TPLMSRepositoryBase<OutStockOrder, int>
, IOutStockOrderRepository, ITransientDependency
        {

            private readonly IActiveTransactionProvider _transactionProvider;


            public OutStockOrderRepository(IDbContextProvider<TPLMSDbContext> 
dbContextProvider):base(dbContextProvider)
            { }

            protected OutStockOrderRepository(IDbContextProvider<TPLMSDbContext> 
dbContextProvider,IActiveTransactionProvider transactionProvider)
                : base(dbContextProvider)
            {

                _transactionProvider = transactionProvider;

            }

 
            public DbCommand CreateCommand(string commandText, CommandType commandType
, params SqlParameter[] parameters)
            {

                EnsureConnectionOpen();
                var dbFacade = Context.Database;
                var connection = Microsoft.EntityFrameworkCore
.RelationalDatabaseFacadeExtensions
.GetDbConnection(dbFacade);

                var command = connection.CreateCommand();
                command.CommandText = commandText;
                command.CommandType = commandType;
                command.Transaction = GetActiveTransaction();
                foreach (var parameter in parameters)
                {
                    command.Parameters.Add(parameter);
                }

                return command;
            }

            DbCommand IOutStockOrderRepository.CreateCommand(string commandText
, CommandType commandType, params object[] parameters)
            {

                EnsureConnectionOpen();
                var dbFacade = Context.Database;
                var connection = Microsoft.EntityFrameworkCore
.RelationalDatabaseFacadeExtensions
.GetDbConnection(dbFacade);

                var command = connection.CreateCommand();
                command.CommandText = commandText;
                command.CommandType = commandType;
                command.Transaction = GetActiveTransaction();
                foreach (var parameter in parameters)
                {
                    command.Parameters.Add(parameter);
                }

                return command;
            }

            private void EnsureConnectionOpen()
            {

                var dbFacade = Context.Database;
                var connection = Microsoft.EntityFrameworkCore
.RelationalDatabaseFacadeExtensions
.GetDbConnection(dbFacade);

                if (connection.State != ConnectionState.Open)
                {

                    connection.Open();
                }

            }
         

            private DbTransaction GetActiveTransaction()
            {

                return (DbTransaction)_transactionProvider.GetActiveTransaction(
new ActiveTransactionProviderArgs
            {

                {"ContextType", typeof(TPLMSDbContext) },
                {"MultiTenancySide", MultiTenancySide }
            });

            }

 

            string IOutStockOrderRepository.GetNo(string name)
            {

                SqlParameter[] parameters = {
                 new SqlParameter("Name",System.Data.SqlDbType.NVarChar,10),
                 new SqlParameter("BH", System.Data.SqlDbType.NVarChar,20)
                                          };

                parameters[0].Value = name;
                parameters[1].Direction = System.Data.ParameterDirection.Output;
                int cnt = Context.Database.ExecuteSqlCommand(

     "EXEC p_NextBH @Name, @BH output",
    parameters);

                string no = parameters[1].Value.ToString();
                if (cnt < 0)
                {
                    no = string.Empty;
                }

                return no;
            }

 
            void IOutStockOrderRepository.ImportInStockOrder(string ids, string no)
            {
                SqlParameter[] parameters = {

                new SqlParameter("id",System.Data.SqlDbType.VarChar,500),
                new SqlParameter("No", System.Data.SqlDbType.NVarChar,20)

         };

                parameters[0].Value = ids + ",";
                parameters[1].Value = no;

                int cnt = Context.Database.ExecuteSqlCommand(
     "EXEC SP_ImportInStockOrder2ODO @id, @No",
    parameters);
            }

        }
    }

5. 在这里我一共使用了两个存储过程，p_NextBH 与SP_ImportInStockOrder2ODO。其中p_NextBH在入库单管理中已经介绍过了。

6. 在这里介绍一下SP_ImportInStockOrder2ODO这个存储过程的实现，代码如下：

Create Proc [dbo].[SP_ImportInStockOrder2ODO]
@id varchar(500),           --id组合
@No nvarchar(20)  --编号
as

 

CREATE TABLE #IdTable(Id int  NULL)

 DECLARE @str VARCHAR(1000)
DECLARE @x xml

select  @str=@id
insert #IdTable
SELECT convert(int,id) id     
FROM (SELECT [value] = CONVERT(XML,'<v>' +REPLACE(@str,',' ,'</v><v>')+ '</v>')) A     
OUTER APPLY ( SELECT id = N.v.value('.' , 'varchar(100)')              
FROM A.[value].nodes('/v') N (v)
) B


DECLARE @BH nvarchar(20),@batch varchar(20),@maxseqno int
select @BH=@No
select @maxseqno=isnull(MAX(seqno),0) from [InStockOrderDetail] where InStockNo= @BH

 
INSERT INTO [dbo].[OutStockOrderDetail]
          ([OutStockNo],[SupplierId],[CargoCode],[HSCode],[CargoName],[Spcf]
           ,[Unit],[Country],[Brand] ,[Curr],[Package],[Length],[Width],[Height],[Qty]
           ,[Vol],[LawfQty],[SecdLawfQty],[Price],[TotalAmt],[GrossWt],[NetWt]
           ,[LawfUnit],[SecdLawfUnit],[Batch],[InStockOrderDetailLocId],[Loc]
,[CreationTime])
   SELECT @BH,supplierid,[CargoCode],[HSCode],[CargoName],[Spcf]
         ,[Unit],[Country],[Brand],[Curr]  ,[Package],[Length],[Width],[Height],0 [Qty]
         ,[Vol] ,0 [LawfQty], 0 [SecdLawfQty] ,[Price],0 [TotalAmt],[GrossWt],[NetWt]
         ,'' [LawfUnit],'' [SecdLawfUnit],batch,id,loc,getdate()

  FROM
  (select row_number() OVER  ( order by b.id) seqno,a.supplierid,[CargoCode],[HSCode]
,[CargoName],[Spcf]
         ,[Unit],[Country],[Brand],[Curr]  ,[Package],[Length],[Width],[Height],0 [Qty]
         ,[Vol] ,0 [LawfQty], 0 [SecdLawfQty] ,[Price],0 [TotalAmt],[GrossWt],[NetWt]
         ,'' [LawfUnit],'' [SecdLawfUnit],b.id,b.loc,Batch
 from [dbo].InStockOrderDetail a inner join InStockOrderDetailLoc b
on a.Id=b.InStockOrderDetailId
left join (select InStockOrderDetailLocId,SUM(isnull(qty,0)) as qty from OutStockOrderDetail
group by InStockOrderDetailLocId
 )c on b.Id=c.InStockOrderDetailLocId
   where b.Qty-ISNULL(c.qty,0)>0
  and b.Id in (select Id from #IdTable)
  ) iso



drop table #IdTable
