[firebird-support] Recursive lookup
Hi, I created a recursive Sql query to lookup the nodes of a thread and where each node is classified according to a tree-structure (the variable Progress_Type_ID in the query which is linked to ID, the primary key of the tree-structure Progress_Type). The following SQL to do the recursive query: /*--Bof query-*/ With Recursive RecurseProgress as ( Select ID, Parent_ID, OldMines_ID, Progress_Type_ID, Progress_Type_Parent_ID, Progress_Type_Description, Instance_Date, Progress, 1 as ALevel from V_OldMines_Progress where Parent_ID is null Union all Select Child.ID, Child.parent_id, Child.OldMines_ID, Child.Progress_Type_ID, Child.Progress_Type_Parent_ID, Child.Progress_Type_Description, Child.Instance_Date, Child.Progress, ALevel + 1 from V_OldMines_Progress Child inner join RecurseProgress as CR1 on Child.parent_ID = CR1.ID ) Select * from RecurseProgress Pr Where Pr.OldMines_ID = :ID order by Pr.ID /*-Eof query--*/ If I execute this query, ID is requested as the parameter Now I want to modify it because Progress_Type_ID is also the primary key of a tree-structure and if I execute the modified query, it must ask for the two parameters, the current ID for the view V_OldMines_Progress and the new starting point of the primary key of table Progress_Type. I tried the following and then it asks for two parameters: ID_ROOTPRGRESSTYPE and ID (any value for ID_ROOTPRGRESSTYPE have the same results): /*-Bof query--*/ With Recursive RecurseProgressType as ( Select ID from Progress_Type where ID = :ID_RootProgressType Union all Select TP.ID from Progress_Type TP, RecurseProgressType Parent where TP.Parent_ID = Parent.id ) , RecurseProgress as ( Select ID, Parent_ID, OldMines_ID, Progress_Type_ID, Progress_Type_Parent_ID, Progress_Type_Description, Instance_Date, Progress, 1 as ALevel from V_OldMines_Progress where Parent_ID is null Union all Select Child.ID, Child.parent_id, Child.OldMines_ID, Child.Progress_Type_ID, Child.Progress_Type_Parent_ID, Child.Progress_Type_Description, Child.Instance_Date, Child.Progress, ALevel + 1 from V_OldMines_Progress Child , RecurseProgressType inner join RecurseProgress as CR1 on Child.parent_ID = CR1.ID ) Select * from RecurseProgress Pr Where Pr.OldMines_ID = :ID order by Pr.ID /*-Eof query--*/ Any idea what I did wrorg?

Hi Nols! I don't quite get what you're trying to do, I'll guess, but feel free to reformulate your problem if my guessing is wrong. My guess is that you're trying to do, is to traverse two trees and join them together. Maybe something like this will be appropriate: /*-Bof query--*/ With Recursive RecurseProgressType as ( Select ID from Progress_Type where ID = :ID_RootProgressType Union all Select TP.ID from Progress_Type TP Inner join RecurseProgressType Parent on TP.Parent_ID = Parent.id ) , RecurseProgress as ( Select ID, Parent_ID, OldMines_ID, Progress_Type_ID, Progress_Type_Parent_ID, Progress_Type_Description, Instance_Date, Progress, 1 as ALevel from V_OldMines_Progress where Parent_ID is null Union all Select Child.ID, Child.parent_id, Child.OldMines_ID, Child.Progress_Type_ID, Child.Progress_Type_Parent_ID, Child.Progress_Type_Description, Child.Instance_Date, Child.Progress, ALevel + 1 from V_OldMines_Progress Child inner join RecurseProgress as CR1 on Child.parent_ID = CR1.ID ) Select * from RecurseProgress Pr Inner join RecurseProgressType RPT on Pr.ProgressTypeID = RPT.ID Where Pr.OldMines_ID = :ID order by Pr.ID, RPT.ID /*-Eof query--*/ HTH, Set
[firebird-support] Fluxo do software
Tenho algumas dúvidas quanto ao fluxo dos softwares: A princípio se usa um programa CAD (AutoCad, Solidworks, etc) para gerar o arquivo 3D .stl certo? Após isso se passa para no netfabb para que o arquivo stl seja preparado/compatível com uma impressão 3D. Então, passa-se pelo Slickr (algo assim) que pega o arquivo STL e gera um GCODE. Nesse GCODE existem as fatias de impressão que contém a espessura de cada uma, temperatura do hot end para cada fatia, velocidade do cooler e etc. É isso? Por fim, o Slickr manda o GCODE para o repetier host que é instalado no PC, que passa pelo cabo usb/rs232 para o Repetier (marlin, etc) na placa Gen7BR/RAMPS/Sethi3d para que o Repetier movimente os motores de passo. Estou certo em meu raciocínio? [Non-text portions of this message have been removed]

Estou certo em meu raciocínio? Two things This is an internation list, so you should write in English, this list is about Firebird (RBDMS) and has no relation with your doubts regarding CAD/CAM systems. Perhaps you post to the wrong list. Good luck ! Duas coisas... Esta é uma lista internacional e deve postar em ingles aqui.. outra coisa, esta lista é sobre Firebird, um gerenciador de banco de dados open source e não tem relação alguma com a tua duvida que é sobre CAD/CAM. Deve ter postado em lista errada... boa sorte !
