xp_cmdshellを使用して複数のファイルをコピーする方法

Question

SQLサーバーから単一のPDFファイルを特定の場所にコピーできます。 しかし、私はそれを複数のファイルでどうやって行うことができますか？

EXEC master..xp_cmdshell 'BCP "SELECT PDF FROM [MEJAMES].[dbo].tblPolicyForms WHERE FormID = 20 " queryout "C:\Users\UserName\Docs\Folder\'+@FileName+'.pdf" -T -N' 

私はフォームID、PDFを持つテーブルが、PDF_Filename

select FormID,PDF,PDF_Filename 
from [dbo].[tblPolicyForms] 

はどのように各フォームIDをループ、PDFファイルを抽出し、それに名前を付けることができますPDF_Filename.pdf？これはあなた何でもして出力リストを定義することができますので、私はカーソルの敗走を行ってきました

CREATE TABLE #tblPolicyForms 
(
    FormID INT NOT NULL 
    ,PDF varbinary(max) NULL 
    ,PDF_FIlename VARCHAR(max) 
) 


INSERT INTO #tblPolicyForms 
SELECT FormID, 
     PDF, 
     PDF_FileName 
FROM [dbo].[tblPolicyForms] 
WHERE FormID IN (19,20,21,22) 
--select * from #tblPolicyForms 

DECLARE @FormID varchar(4); 
DECLARE @FileName VARCHAR(200); 

DECLARE FormID_cursor CURSOR FOR 
SELECT 
    FormID 
    ,PDF_FIlename 
FROM 
    #tblPolicyForms 
WHERE FormID IN (19,20,21,22) 
--where whatever conditions you need to get the FormIDs you want to use 


OPEN FormID_cursor 

FETCH NEXT FROM FormID_cursor 
INTO @FormID, @FileName 

WHILE @@FETCH_STATUS = 0 
BEGIN 

    EXEC master.dbo.xp_cmdshell 'BCP "SELECT PDF FROM [DBname].[dbo].tblPolicyForms " queryout "C:\Users\UserName\Documents\ExportDir\'+@FileName+'" -T -N' 


FETCH NEXT FROM FormID_cursor 
INTO @FormID, @FileName 

END 

CLOSE FormID_cursor 
DEALLOCATE FormID_cursor

望む

CREATE TABLE #tblPolicyForms 
(
    FormID INT NOT NULL 
    ,PDF TEXT NULL 
    ,PDF_FIlename VARCHAR(200) 
) 


INSERT INTO #tblPolicyForms 
    VALUES(18, 'skjdfsakdjfhsldkfhsdlkjfhsdkfjh', 'PDF18Name.pdf') 
    ,(19, 'skjdfsakdjfhsldkfhsdlkjfhsdkfjh', 'PDF19Name.pdf') 
    ,(20, 'skjdfsakdjfhsldkfhsdlkjfhsdkfjh', 'PDF20Name.pdf') 
    ,(21, 'skjdfsakdjfhsldkfhsdlkjfhsdkfjh', 'PDF21Name.pdf') 
    ,(22, 'skjdfsakdjfhsldkfhsdlkjfhsdkfjh', 'PDF22Name.pdf')

DECLARE @FormID varchar(4); 
DECLARE @FileName VARCHAR(200); 

DECLARE FormID_cursor CURSOR FOR 
SELECT

    ,PDF_FIlename 
FROM 
    #tblPolicyForms 
--where whatever conditions you need to get the FormIDs you want to use 


OPEN FormID_cursor 

FETCH NEXT FROM FormID_cursor 
INTO @FormID, @FileName 

WHILE @@FETCH_STATUS = 0 
BEGIN 

    EXEC master.dbo.xp_cmdshell 'BCP "SELECT PDF FROM [MEJAMES].[dbo].tblPolicyForms WHERE FormID = '+@FormID+' " queryout "C:\Users\UserName\Docs\Folder\'+@FileName+'.pdf" -T -N'

Answer 2

DECLARE @FormID varchar(4); 
DECLARE @FileName VARCHAR(200); 
DECLARE @CmdString VARCHAR(2000); 

DECLARE FormID_cursor CURSOR FOR 
SELECT 
    FormID 
    ,PDF_FIlename 
FROM 
    [dbo].[tblPolicyForms] 
WHERE 
    FormID IN (19,20,21,22) 
--where whatever conditions you need to get the FormIDs you want to use 


OPEN FormID_cursor 

FETCH NEXT FROM FormID_cursor 
INTO @FormID, @FileName 

WHILE @@FETCH_STATUS = 0 
BEGIN 

    SET @CmdString = 'BCP "SELECT PDF FROM [dbo].[tblPolicyForms] where FormID = '+@FormID+' " queryout "C:\Users\UserName\Documents\ExportDir\'+@FileName+'" -T -N'; 
    EXEC master.dbo.xp_cmdshell @CmdString; 

FETCH NEXT FROM FormID_cursor 
INTO @FormID, @FileName 

END 

CLOSE FormID_cursor 
DEALLOCATE FormID_cursor
