Submitted by: @cincuranet

The FbCommand.ExecuteNonQuery should return -1 for everything except insert, update, delete, according to "spec".

https://docs.microsoft.com/en-us/dotnet/api/system.data.common.dbcommand.executenonquery

"For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. For all other types of statements, the return value is -1."
