inner join به یک جدول چندین مرتبه
با سلام
من دو تا جدول دارم به صورت زیر:
CREATE TABLE [dbo].[tblSF22Welding](
[BarcodeId] [bigint] NOT NULL,
[DT] [datetime] NULL,
[S1Leak1] [int] NULL,
[S1Leak2] [int] NULL,
[S1Leak3] [int] NULL,
[S1Leak4] [int] NULL,
[S1Leak5] [int] NULL,
[S1Leak6] [int] NULL,
[S1Leak7] [int] NULL,
[S1Leak8] [int] NULL,
[S1Leak9] [int] NULL,
[S1Leak10] [int] NULL,
) ON [PRIMARY]
CREATE TABLE [dbo].[tblSF26Log](
[TestId] [bigint] IDENTITY(1,1) NOT NULL,
[BarcodeId] [bigint] NULL,
[DT] [datetime] NULL,
[Ok1] [bit] NULL,
[Ok2] [bit] NULL,
[Ok3] [bit] NULL,
[Ok4] [bit] NULL,
[Ok5] [bit] NULL,
[Ok6] [bit] NULL,
[Ok7] [bit] NULL,
[Ok8] [bit] NULL,
[Ok9] [bit] NULL,
[Ok10] [bit] NULL,
[OperatorId] [int] NULL,
[QCUserId] [int] NULL,
[QCManOk] [bit] NULL,
)
من نیاز دارم ده بار جدول tblSF22Welding را با tblSF26Log جوین کنم. کوئری زیر را نوشته ام اما اجرای آن حدود 30 ثانیه طول می کشد. جدول tblSF22Welding تا حالا حدود 20000 رکورد دارد و جدول tblSF26Log حدود 60000 و این فقط برای یک ماه است و به زودی رکوردهای این جدول ها به چند میلیون می رسد! آیا راه مناسب تری هم وجود دارد؟
