I got an SQL Server 2008 R2 and a SharePoint Server. I have put up a BCS between the two servers. Reading data through a External List. This worked fine yesterday. But to day I got this error:
The query against the database caused an error.
w3wp.exe (0x0CB4)-0x1AD8-SharePoint Foundation-Logging Correlation Data-xmnv-Medium Name=Request (POST:http://External%20List/Read%20List.aspx)-7ebc312e-db3a-46a4fbe-04b0115c4885
Some of the guys I work with have reset the IIS, can this be the problem?
