Question

我的桌子大约有60000行。我正在使用MS SQL Server Express 2012。

更新时，需要很长时间才能完成。

我的桌面设计如下。

CREATE TABLE [dbo].[Entry_Jangad_Lot](
[Srno] [bigint] IDENTITY(1,1) NOT NULL,
[Kapan] [nvarchar](50) NOT NULL,
[Lotno] [int] NOT NULL,
[Quality] [nvarchar](50) NOT NULL,
[Pcs] [int] NOT NULL,
[Caret] [decimal](18, 2) NOT NULL,
[JangadNo] [int] NOT NULL,
[IssuedTo] [nvarchar](50) NULL,
[IssuedDate] [nvarchar](50) NULL,
[Status] [nvarchar](50) NULL,
[ReceivedPcs] [int] NULL,
[ReceivedCaret] [decimal](18, 2) NULL,
[ReceivedDate] [nvarchar](50) NULL,
[ReceivedType] [nvarchar](50) NULL,
[Position] [nvarchar](50) NULL,
[Process] [nvarchar](50) NULL,
[MergedStatus] [nvarchar](50) NULL,
[MergedToLotno] [int] NULL,
CONSTRAINT [PK_Entry_Jangad_Lot_1] PRIMARY KEY CLUSTERED 
(
    [Srno] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY =   OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

我正在使用以下过程来更新表记录。

CREATE procedure [dbo].[sp_add_update_lot_receive]
(
@mode nvarchar(50),
@Kapan nvarchar(50),
@Lotno int,
@ReceivedPcs int,
@ReceivedCaret decimal(18,2),
@ReceivedDate nvarchar(50),
@ReceivedType nvarchar(50)
)
as
if @mode='ADD'
begin
    declare @srno int
    select @srno=srno from Entry_Jangad_Lot where Kapan=@Kapan
    and Lotno=@Lotno
    and Position='CURRENT'

    update Entry_Jangad_Lot set
    ReceivedPcs=@ReceivedPcs,
    ReceivedCaret=@ReceivedCaret,
    ReceivedDate=@ReceivedDate,
    ReceivedType=@ReceivedType,
    Status='RECEIVED'
    where srno=@srno
    --where Kapan=@Kapan
    --and Lotno=@Lotno
    --and Position='CURRENT'

    if @ReceivedType='POLISH'
    begin
        update Entry_Jangad_Lot set
        Process='POLISH'
        where srno=@srno
        --where Kapan=@Kapan
        --and Lotno=@Lotno
        --and Position='CURRENT'

    end
    else
    begin
        if @ReceivedType='TABLE'
        begin
            update Entry_Jangad_Lot set
            Process='TABLE'
            where srno=@srno
            --where Kapan=@Kapan
            --and Lotno=@Lotno
            --and Position='CURRENT'
        end
        else
        begin
            update Entry_Jangad_Lot set
            Process='NOTPOLISH'
            where srno=@srno
            --where Kapan=@Kapan
            --and Lotno=@Lotno
            --and Position='CURRENT'
        end

    end
end
GO

也可以使用以下索引。

ALTER TABLE [dbo].[Entry_Jangad_Lot] ADD  CONSTRAINT [PK_Entry_Jangad_Lot_1] PRIMARY KEY CLUSTERED 
(
    [Srno] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
GO


CREATE NONCLUSTERED INDEX [NonClusteredIndex-20150422-160201] ON [dbo].[Entry_Jangad_Lot]
(
    [Kapan] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
GO


CREATE NONCLUSTERED INDEX [NonClusteredIndex-20150422-155655] ON [dbo].[Entry_Jangad_Lot]
(
    [Kapan] ASC,
    [Lotno] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
GO

修改

DECLARE @return_value int

EXEC @return_value = [dbo]。[sp_add_update_lot_receive] @mode =   N＆＃39; ADD＆＃39;，@ Kapan = N＆＃39; / SL＆＃39;，@ Point = 164，@ ReceivedPcs = 300，         @ReceivedCaret = 2.90，@ ReceivedDate = N＆＃39; 27/04 / 2015＆＃39;，         @ReceivedType = N＆＃39; POLISH＆＃39;

SELECT＆＃39;返回值＆＃39; = @return_value

GO

Answer 1

如果我理解你的逻辑，那么这不是更简单的做法：

CREATE procedure [dbo].[sp_add_update_lot_receive]
(
@mode nvarchar(50),
@Kapan nvarchar(50),
@Lotno int,
@ReceivedPcs int,
@ReceivedCaret decimal(18,2),
@ReceivedDate nvarchar(50),
@ReceivedType nvarchar(50)
)
as
if @mode='ADD'
begin

    update Entry_Jangad_Lot set
    ReceivedPcs=@ReceivedPcs,
    ReceivedCaret=@ReceivedCaret,
    ReceivedDate=@ReceivedDate,
    ReceivedType=@ReceivedType,
    Status='RECEIVED',

    Process = coalesce (t.Process, 'NOTPOLISH')

    from Entry_Jangad_Lot
    outer apply (values
        ('TABLE'),
        ('POLISH')
    ) t(Process)

    where Kapan=@Kapan
      and Lotno=@Lotno
      and Position='CURRENT'

      and t.Process = Entry_Jangad_Lot.Process
end

Answer 2

看起来并不太糟糕。如果我不得不猜测（我这样做是因为我不在SQL Server Express附近），我会说这是因为你在索引上有一个INT srno转换为BIGINT版本。这可能导致隐式转换停止使用索引。

另外，你有一个不需要的索引（Kapan和Lotno的索引也只是Kapan）。

另外，定义“长时间”：）

更新需要太长时间
