[Firebird-net-provider] FbCommand.Prepare() causes ExecuteScalar() to return null

[Mike S. <mi...@mi...>]

Hi Carlos

Further to the problem with FbCommand.ExecuteScalar() returning null in 
1.7, I've found that it also returns null if I call FbCommand.Prepare() 
before executing the command. Let me know if you need a test case.

Cheers,
