SSIS动态Excel目标文件名

Question

如何配置数据流任务，该任务从MS SQL Server 2008数据源获取数据并将其放入一个文件名看起来像“日期文件名” .xls的Excel文件中？

Answer 1

Excel is the biggest pain to deal with in SSIS. Usually I store a template file that just has the column headers and nothing else. I start with a task to copy the template file to the processing directory. You can use variables to create the file name in an expression at this point. Alternatively, you can create the file in the dataflow and then rename the file in a step after the data flow. With text files, I have dynamically created the connection in an expression, but Excel seems to be funny about that.

Answer 2

Provided that your column definition don't change.... you can go to

1. Right Click on Excel Connection Manager
2. Expression
3. Select connectionstring
4. bulid expression (for Example : (DT_WSTR, 50) GETDATE() + @[user::FileName] +".xlsx")

Answer 3

Select the properties for Excel Connection Manager instance, Click on the ellipsis for 'Expressions 'property and set an expression for 'ExcelFilePath' to a variable with a valid path to an excel file, this takes cares of the connection string.

You do need a variable valid excel file at the design time, otherwise connection manager does not work, you can overwrite it at run time using a script task to point to the excel file that does not exist at design time.

Answer 4

HLGEM's answer certainly helps. As @sql-rookie requested, I'll provide a sample about how to copy the excel file to a new file named with current date. Hope this will help others with the same question in the future.

Basically you just need to add an additional File System Task after the Data Flow Task . And use a variable for the Destination File Path: "\\\\\\\\file\\\\"+SUBSTRING((DT_STR,30, 1252) GETDATE(), 1, 10) +".xlsx"
