What steps will reproduce the problem?

2. open a connection to an Oracle 10 or 11 db

Interesting, I am not sure there is an easy way to create a db independent test 
case family. stored procs, temp tables, information schema etc, all differ. 

I would however be happy to have a test suite for oracle if you feel like 
committing a patch to dapper.contrib.

simplest would be to clone the repo on google code, port the test file and add 
it to the Dapper.Test project actually ... maybe create TestOracle.cs ... then 
we can add a compile flag for oracle

There are 4 projects

Dapper
DapperNET35
Dapper.Contrib
Dapper.Contrib.Tests
DapperTest

I don't see a project Dapper.Test with the dot between them so assume you
mean DapperTest and add a file (OracleTests.cs) that is
the functional equivalent as Tests.cs but for Oracle.

Sam,

Just now getting around to this..sorry.

Anyways it seems that the Oracle .NET provider tries to validate every
statement in the command object and will not let you construct a malformed
query, at least one without a 'From' clause. Guess the simple examples have
to be commented out for right now,or I can did in and see if there may be a
way to turn off validation on the command object.
