FAQ
Which package should I choose if I need assistance with a stored procedure, function or trigger?
Effort is calculated based on the total number of tables involved, directly or indirectly, in the SQL script. For example, if your stored procedure updates data in 5 tables, you should choose the Standard Package.
I have special requirements that are not specified in the available packages, can you help me?
Of course. Feel free to contact me detailing your requirements, so I'll be able to offer you a custom order.
