# 2522 Queries That Return Insensitive Result Sets Cause #600 File Manager Error With Temporary Tables Path

The following SQL query causes this error with the ElevateDB .Net Data Provider:

ElevateDB Error #600 File manager error (Cannot create file "C:\Documents and Settings\Administrator\Local Settings\Temp\"\SVR01605210Tutorial1.EDBTbl (OS Error: Warning: A StringBuilder buffer has been overflowed by unmanaged code. The process may become unstable. Insufficient capacity allocated to the StringBuilder before marshaling it.))

Comments

The issue was a cascading failure that was originally caused by the fact that the base DbConnectionStringBuilder object in .Net escapes (with double-quotes) any connection string settings with spaces in them. This caused the creation of any temporary tables to fail due to the invalid temporary tables path with the embedded double-quotes. This in turn exposed a bug in the EDB .Net Data Provider where the calls to retrieve the system error message weren't setting the proper StringBuilder length prior to passing it to the call.

Resolution

Fixed Problem on 1/12/2008 in version 1.07 build 2
