how to use parametric queries from .NET with Firebird?
I have always been using parameters with stored procedures. like this
             FbCommand cmd = new FbCommand("select * from 
SP_myprocedure(?);");
             cmd.CommandType = CommandType.StoredProcedure;
             cmd.Parameters.Add("@myparameter", FbDbType.Text).Value = 
myparameter;

this works very well. but now I have just a query where I need to add 
several parameter inputs. I have changed the CommandType to Text and 
tried adding parameter into query for example "select field1, field2 
from table1 where field1=:myparameter;"

but can't get it to work. how should it be done?
