使用SSIS将动态Excel工作表加载到SQL中

Question

I'm trying to load multiple excel format files (.xlsx) into sql. I have set up my package as followed. My excel files name and sheet name will change daily

File name: PROD File Tracking 02-10.xlsx - Month and Day change daily
Sheet name: 2-10$ -- month and day change daily

Package Structure

For each Loop Container -> Data Flow Task -> Excel Source -> OLE DB Destination

Variables Values

1. FileName: Z:\\Users\\darsftp\\BDS\\GBRTest\\PROD File Tracking 02-10.xlsx
2. FolderPath: Z:\\Users\\darsftp\\BDS\\GBRTest
3. ExtProperties: "Excel 12.0;HDR=Yes"

Need Help

To dynamically pick up file daily with a dynamic sheet name.

I know how to pick up files with a dynamic file name but not with a dynamic sheet name. That's where I'm having the issue.

Answer 1

Create a new variable Sheetname and Set it's property Evaluate as expression to True and use the following expression:

REPLACE(SUBSTRING(@[User::Filename],FINDSTRING(@[User::Filename],"PROD File Tracking", 1 ) + LEN("PROD File Tracking"),100),".xlsx","") + "$"

So if your Filename variable value its Z:\\Users\\darsftp\\BDS\\GBRTest\\PROD File Tracking 02-10.xlsx so Sheetname variable value will be 02-10$ wich is the sheetname.

And in your Excel Source read the sheetname from variable Sheetname

Side note: Excel sheetname always end with $ sign (it doesn't appear in excel)

EDIT 1

You have to add an expression the the Excel connection manager connection string property:

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source="+ @[User::Filename] + ";Extended Properties=\"Excel 12.0;HDR=YES\";"

Set DelayValidation property of Data Flow task to True.
