[Haskelldb-users] possible bug in haskelldb

[Jeremy S. <jer...@li...>]

Hello,

I may have discovered a bug in haskelldb. Here is a simplified version
of the what is wrong -- I have not tested to see if the simplified
version actually exhibits the bug.

Lets say table A has a column 'name' and table B has a column 'name'.

If I do something like:

import qualified MyDatabase.A as A
import qualified MyDatabase.B as B

query = do a <- table A.a
	   b <- table B.b
	   project ( A.name << a!A.name #
		     B.name << b!B.name
                   )



If I use the results of the query, b!B.name gets a!A.name's
value[1]. If I change the project to:

	   project ( B.name << b!B.name #
		     A.name << a!A.name 
                   )

Then the a!A.name gets b!B.name's value.

[1] or maybe its the other way around, I don't remember.


In any case, is this a know bug? Am I doing something wrong?

If this simple case does not actually exhibit the behaviour I am
seeing, I can do some additional testing and figure out the test case
that does.

I am using the nightly snapshot from 20040502.

Thanks!
Jeremy Shaw.
