I'm doing queries on .dbf files.
When I have 5 inner join clause
there is this error

-2147467259 (80004005)
[Microsoft][ ODBC dbase Driver ] Unexpected error from external database driver
If I run this query in Acces or in Paradox there's no problem and the data comes out (select statement)

I tried two connection strings
conADO.ConnectionString = "Provider=MSDASQL.1;Persist Security Info=False;Extended Properties=""DSN=dBASE Files;DBQ=" & strDatabaseImos & ";DefaultDir=" & strDatabase & ";DriverId=533;MaxBufferSize=2048;PageTimeout= 5;"" "

and this one
conADO.ConnectionString = "Driver={Microsoft dBASE Driver (*.dbf)}; DriverID=277; Dbq=" & strDatabase & ";"


the same error came out.

I look in google and msdn and find nothing interresting.
Somebody got an idea ? or need more information ?
