明示的な値は、私は次のコマンドを持っているテーブルにID列に対するSQLクエリエディタで

Question

を指定する必要があります。test.txtというの

SET IDENTITY_INSERT tUserPreference ON 

BULK INSERT tUserPreference 
FROM 'D:\test.txt' 
WITH 
( KEEPIDENTITY, 
    BATCHSIZE = 2, 
    FIRSTROW = 2, 
    FIELDTERMINATOR = ',' , 
    ROWTERMINATOR = '\n', 
    DATAFILETYPE = 'char', 
    KEEPNULLS 
    ); 
SET IDENTITY_INSERT tUserPreference OFF 
GO 

内容：

"UserPreferenceId","UserId","UserPreferenceValue","UserPreferenceTypeId" 
7858,1194,"FSP,FRB,FWF,FBVS,FRRC",15 
7859,1194,"FIRM",21 
7860,1194,"009,61,114,142,174,233,262,286,303,325,369,389,411,671,690,735,938,943,977,105,200",11 
7861,1194,"B545,B441",12 
7862,1194,"{"FIRM":{"accountType":"Firm","timeInForce":"DAY","routing":"DNR","isAllOrNone":false}}",2 

しかし、私はこれらのコマンドを実行します私は次の結果を参照してください。

Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 2, column 4 (UserPreferenceTypeId). 
Msg 2627, Level 14, State 1, Line 3 
Violation of PRIMARY KEY constraint 'PK_tUserPreference_UserPreferenceId'. Cannot insert duplicate key in object 'dbo.tUserPreference'. The duplicate key value is (7859). 
The statement has been terminated. 

のみ1行挿入（7861,1194,"B545,B441",12）

テーブルスクリプト作成：

CREATE TABLE [dbo].[tUserPreference](
    [UserPreferenceId] [int] IDENTITY(1,1) NOT NULL, 
    [UserId] [int] NULL, 
    [UserPreferenceValue] [varchar](max) NULL, 
    [UserPreferenceTypeId] [int] NOT NULL, 
CONSTRAINT [PK_tUserPreference_UserPreferenceId] PRIMARY KEY CLUSTERED 
.... 

適切に一括挿入を使用して挿入する方法を？

Answer 1

CREATE TABLE tUserPreference1 (DataField VARCHAR(1000)) 

BULK INSERT tUserPreference1 
FROM 'C:\Shared\text.txt' 
WITH 
( 
    FIRSTROW = 2, 
    ROWTERMINATOR = '\n', 
    DATAFILETYPE = 'char', 
    KEEPNULLS 
    ); 

select SUBSTRING(DataField,1,4) AS UserPreferenceId 
     ,SUBSTRING(DataField,6,4) AS UserId 
     ,REVERSE(SUBSTRING(REVERSE(DataField),1,CHARINDEX(',',REVERSE(DataField))-1)) UserPreferenceTypeId 
     ,DataField 
INTO tUserPreference2 
from tUserPreference1 

SELECT * 
     ,SUBSTRING(DataField,11,LEN(DataField)-(11+LEN(UserPreferenceTypeId))) AS UserPreferenceValue 
FROM tUserPreference2
