hello everyone,
how do calculate the total (of a year) of the quantities of a product sent to a location (> 10000 moves)? Is there a specific method to have this type of data (statistics)?
Other question: calculate the quantities of product sent to a location divided by month and by type of document (customer shipment, internal shipment, customer return shipment)
Thanks
You must write a SQL query like:
SELECT SUM(internal_quantity) FROM stock_move WHERE to_location = ? AND product = ? AND state = 'done';
You can add a GROUP BY
clause.
More over, you can use this query in ModelSQL.table_query
to display the result in the client.
Can it be used via RPC?
If YES, with which model?
A ModelSQL with a table_query behaves exactly like any other ModelSQL (except for create, write and delete which are forbidden).
I never used “ModelSQL”. I’ve always used “ModelStorage”.
Usually through RPC, with “ModelStorage”, I use the syntax:
model.stock.move.search ([('product', '=', 8), ('to_location', '=', 259), ('state', '=', 'done')], 0, 1000, None, <CONTEXT>)
If I wanted to use “ModelSql” what is the syntax to use?
I have tried with:
model.table_query (['SELECT SUM (internal_quantity) FROM stock_move WHERE to_location = 259 AND product = 8 AND state = "done"'], <CONTEXT>)
But I get nothing …
ModelSQL inherits from ModelStorage. Indeed it is an implementation of the ModelStorage for the SQL backend. So you just need to use the same API.
By the way, stock.move
is a ModelSQL subclass.
I’m sorry, but I can’t get results …
I can’t find examples of using table_query.

model.stock.move.table_query (['SELECT SUM (internal_quantity) FROM stock_move WHERE to_location = 259 AND product = 8 AND state = "done"'], <CONTEXT>)
but I don’t get results.
What is the correct command syntax?
Could you give me an example that I can test?
Thanks
You must define a new ModelSQL that you will query.
Here is an example: https://hg.tryton.org/modules/timesheet/file/ee4b51fe0754/line.py#l230
