If the System.Data.ParameterDirection is Output, and execution of the associated Devart.Common.DbCommand does not return a value, the DbParameterBase will contain a null value. Null values are handled using the System.DBNull class.
After the last row from the last result set is read, the Output, InputOut, and ReturnValue parameters are updated.
Output parameters are supported for stored procedures only.
When executing stored procedures you have to create Devart.Common.DbParameter with Devart.Common.DbParameter.Direction set to ReturnValue or set ParameterCheck property to true.
