使用OUTPUT子句插入不在INSERTED中的值

Question

I am writing a stored procedure to process a table belonging to an application and insert values into a table belonging to the same application (so I cannot amend either table).

I have to process only new records and remember which records have been processed, for this I have created a third simple table.

Tables are below, many columns removed to leave only important details.

Source Table

CREATE TABLE [dbo].[DETAIL](
    [DET_NET] [float] NULL,
    [DET_VAT] [float] NULL,
    [DET_VATCODE] [varchar](4) NULL,
    [DET_GROSS] [float] NULL,
    [DET_DATE] [datetime] NULL,
    [DET_PRIMARY] [float] NOT NULL
)

Target Table

CREATE TABLE [dbo].[TRN_TEMP](
    [TRN_TRAN_DATE] [datetime] NULL,
    [TRN_DESCRIPTION] [varchar](20) NULL,
    [TRN_PRIMARY] [int] NULL,
    [TRN_AMT] [float] NULL
)

Tracking Table

CREATE TABLE REGISTER(
    LINE_ID INT IDENTITY(1,1) PRIMARY KEY CLUSTERED NOT NULL,
    DET_PRIMARY_LINK FLOAT NOT NULL,
    INS_DATE DATETIME NOT NULL
)

I am trying to insert into the Target table values from the source table, but also insert the primary key of the source table into the tracking table.

INSERT INTO TRN_TEMP (TRN_TRAN_DATE, TRN_DESCRIPTION, TRN_AMT)
OUTPUT D.DET_PRIMARY, GETDATE() INTO REGISTER (DET_PRIMARY_LINK, INS_DATE)
SELECT D.DET_DATE, 'SOMETEXT', SUM(D.DET_NET)
FROM DETAIL D
LEFT JOIN REGISTER R ON D.DET_PRIMARY = R.DET_PRIMARY_LINK
WHERE <MY CONDITIONS> AND R.LINE_ID IS NULL -- TO REMOVE LINES ALREADY PROCESSED
GROUP BY D.DET_DATE

I can't see a problem with the text above but I get an error "The multi part identifier 'D.DET_PRIMARY' could not be bound.". I've tried both D.DET_DETAIL and DETAIL.DET_DETAIL and the error is the same.

Is it not possible to use values from the source table in the OUTPUT clause when using a group or do I have an error in the formatting? If it's not possible is there another way of keeping track of which lines I have processed?

Answer 1

Use MERGE instead of INSERT :

MERGE
INTO    trn_temp d
USING   (
        SELECT  D.DET_DATE, 'SOMETEXT' AS sometext, SUM(D.DET_NET) AS the_sum
        ...
        ) s
ON      (1 = 0)
WHEN NOT MATCHED THEN
INSERT  (TRN_TRAN_DATE, TRN_DESCRIPTION, TRN_AMT)
VALUES  (det_date, sometext, the_sum)
OUTPUT  s.*

Update:

To work around the GROUP BY problem, use this:

DECLARE @tmp TABLE
        (
        det_primary INT NOT NULL PRIMARY KEY
        )

MERGE
INTO    register r
USING   detail d
ON      (r.det_primary_link = d.det_primary)
WHEN NOT MATCHED THEN
INSERT  (det_primary_link, ins_date)
VALUES  (det_primary, GETDATE())
OUTPUT  d.det_primary
INTO    @tmp;

INSERT
INTO    trn_temp (trn_tran_date, trn_description, trn_amt)
OUTPUT  INSERTED.*
SELECT  det_date, 'sometext', SUM(det_net)
FROM    @tmp t
JOIN    detail d
ON      d.det_primary = t.det_primary
GROUP BY
        det_date

I know this question is nearly a year old, but your insert can work as you have presented it if you select the proper column name from the OUTPUT

The output clause gives us one of two possible virtual tables, inserted or deleted, depending on the operation, an update operation gives both. Since you don't have a field name DET_DATE in your TRN_TEMP table that you just inserted into, it is invalid in the output statement.

INSERT INTO TRN_TEMP (TRN_TRAN_DATE, TRN_DESCRIPTION, TRN_AMT)
OUTPUT INSERTED.TRN_TRAN_DATE, GETDATE() 
INTO REGISTER (DET_PRIMARY_LINK, INS_DATE)
SELECT D.DET_DATE, 'SOMETEXT', SUM(D.DET_NET)
FROM DETAIL D
LEFT JOIN REGISTER R ON D.DET_PRIMARY = R.DET_PRIMARY_LINK
WHERE <MY CONDITIONS> AND R.LINE_ID IS NULL -- TO REMOVE LINES ALREADY PROCESSED
GROUP BY D.DET_DATE
