在带有ODBC的SSRS中使用.CSV作为数据源：数据集可以查询列，但运行时报表无法连接到数据源

Question

Application: Report Builder Connection Type: ODBC

I am attempting to connect to, and query a csv using SSRS. I've added a system DSN, and am able to successfully connect when I click the "Test Connection" button on the "Connection Properties" window. However when I click the same button within the "Data Source Properties" window, I get the error message below.

ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

What's strange is that I created a dataset with a simple SELECT * query FROM [csvfilename], and it successfully displays all the fields from my csv. I therefore know it can access it. When I try to run the report, however, I get the error below.

Cannot create a connection to data source '[DataSource Name]' (rsErrorOpeningConnection)

Here is the Connection String I'm using within my DataSource:

Dsn=WIPEXPORT;Driver=Microsoft Text Driver (*.txt;dbq=I:\\HARVEST\\DATA BROWSERS\\WIPEXPORT;defaultdir=I:\\HARVEST\\DATA BROWSERS\\WIPEXPORT;driverid=27;fil=text;maxbuffersize=2048;maxscanrows=8;pagetimeout=5;safetransactions=0;threads=3;usercommitsync=Yes

I apologize if this has already been answered. I couldn't seem to find anyone with my specific problem.

Answer 1

So after trying just about every connection string configuration within ReportBuilder, I ended up switching to VisualStudio where it worked immediately. I even copied the successful connection string from VS back to RB and RB was still broken. Don't know if it's my RB installation or what, but at least it works now.
