I happen to face an error when I try to call the biosphere flows of activity. And When I call the technosphere for different activities, it works fine.
However, for the biosphere:
[in] clinker_bio_exchange = [exc for exc in clinker.biosphere()]
clinker_bio_exchange
Error:
ActivityDatasetDoesNotExist: <Model: ActivityDataset> instance matching query does not exist:
SQL: SELECT "t1"."id", "t1"."data", "t1"."code", "t1"."database", "t1"."location", "t1"."name", "t1"."product", "t1"."type" FROM "activitydataset" AS "t1" WHERE (("t1"."database" = ?) AND ("t1"."code" = ?)) ORDER BY Random() LIMIT ? OFFSET ?
Params: ['biosphere3', 'fc1c42ce-a759-49fa-b987-f1ec5e503db1', 1, 0]
Should I update any part or am I missing something? Thank you.
There is something wrong with your biosphere3 database - your clinker object has an exchange with the biosphere flow (activity) ('biosphere3', 'fc1c42ce-a759-49fa-b987-f1ec5e503db1') (which is Water, cooling, unspecified natural origin on my machine). However, you are either missing the biosphere3 database entirely, or have deleted or otherwise modified this specific flow.
The easiest way to fix this is to reinstall it:
import bw2io
bw2io.create_default_biosphere3()

It seems to be a simple question but I have a hard time to find an answer to it. I already have a project with several parameters (project and database parameters). I would like to obtain the LCA results for several scenarios with my parameters having different values each time. I was thinking of the following simple procedure:
change the parameters' value,
update the exchanges in my project,
calculate the LCA results.
I know that the answer should be in the documentation somewhere, but I have a hard time to understand how I should apply it to my ProjectParameters, DatabaseParameters and ActivityParameters.
Thanks in advance!
EDIT: Thanks to #Nabla, I was able to come up with this:
For ProjectParameter
for pjparam in ProjectParameter.select():
if pjparam.name=='my_param_name':
break
pjparam.amount = 3
pjparam.save()
bw.parameters.recalculate()
For DatabaseParameter
for dbparam in DatabaseParameter.select():
if dbparam.name=='my_param_name':
break
dbparam.amount = 3
dbparam.save()
bw.parameters.recalculate()
For ActivityParameter
for param in ActivityParameter.select():
if param.name=='my_param_name':
break
param.amount = 3
param.save()
param.recalculate_exchanges(param.group)
You could import DatabaseParameter and ActivityParameter iterate until you find the parameter you want to change, update the value, save it and recalculate the exchanges. I think you need to do it in tiers. First you update the project parameters (if any) then the database parameters that may depend on project parameters and then the activity parameters that depend on them.
A simplified case without project parameters:
from bw2data.parameters import ActivityParameter,DatabaseParameter
# find the database parameter to be updated
for dbparam in DatabaseParameter.select():
if (dbparam.database == uncertain_db.name) and (dbparam.name=='foo'):
break
dbparam.amount = 3
dbparam.save()
#there is also this method if foruma depend on something else
#dbparam.recalculate(uncertain_db.name)
# here updating the exchanges of a particular activity (act)
for param in ActivityParameter.select():
if param.group == ":".join(act.key):
param.recalculate_exchanges(param.group)
you may want to update all the activities in the project instead of a single one like in the example. you just need to change the condition when looping through the activity parameters.
I want to mention that I'm new to SSAS and MDX.
In the past several days I've been dwelling with an excel generated query that errors out.
The problem is that a query is generated by excel when trying to read data from an online cube data source preventing other reads for that cube. The query is executed against an AZURE cube and I manage to profile it and get the following query:
with set __XLUniqueNames as {[Stores].[Chain].[Chain].&[SuperBrugsen], [Stores].[Chain].[Chain].&[Salling], [Stores].[Chain].[Chain].&[SuperBrugsen] }
set __XLDrilledUp as
Generate(__XLUniqueNames,
{ IIF([Stores].[Chain].currentmember.LEVEL_NUMBER <= 2147483647,
[Stores].[Chain].currentmember,
Ancestor([Stores].[Chain].currentmember,
[Stores].[Chain].currentmember.LEVEL_NUMBER - 2147483647)) } )
member [Measures].__XLPath as
Generate(
Ascendants([Stores].[Chain].currentmember),
[Stores].[Chain].currentmember.unique_name,
"__XLPSEP")
select { [Measures].__XLPath } on 0,
__XLDrilledUp on 1
from [SomeCube]
cell properties value
Each time query contains more than one member (an existing member from that dimension) it errors out with this message:
"Either you do not have permission to access the specified member or the specified member does not exist.".
What I have tried:
First, I tried to identify a pattern of member combinations that errors out, with no luck. It seems that for some certain members I get the error and for some, It doesn't. For single member, duplicate members and combination of members that don't exist in the cube it doesn't error.
Second, I did try the query on a different cube (on-premise SSAS) and I didn't get the error.
Third, by modifying the connection string I tried to make Excel ignore the missing members in the hope it will work using the "MDXMissingMemberMode" flag set to Ignore. I didn't work.
Forth, I tried to dissect the query to see which clause was giving the error. With my limited knowledge of MDX I suspect that "currentmember" with its "LEVEL_NUMBER" property is at fault. My guess is that it fails to get the current member for the next member in the set.
Fifth, the last thing and the longest, by accident I discovered that in SSMS you can execute a query in an mdx session (Right-click on cube -> New query) or you can open the cube in browse mode (Right-click on cube -> Browse) which results in a UI similar to the mdx query like.
No here comes the surprise, in this browse "mode" my query executes successfully each time. Intrigued by this I started to profile the request and see what was different. The difference was some additional xml structure like a list with properties. Seeing this I figured I could manipulate my connection string from excel to send some of the properties to make it work, but in the end, I didn't work.

This all the info that I could gather for my problem. My next step is to get to Microsoft for help by I don't want to do that just yet due to the costs.
Can someone of you guys please help me out? any ideas or suggestion are most welcomed because I ran out of ideas.
It seems that the problem solved itself. Most likely there was an update that solved this issue. Ref. to azure update logs page: https://azure.microsoft.com/en-us/updates/?product=analysis-services&status=nowavailable
I have created a non-persistent attribute in my WoActivity table named VDS_COMPLETE. it is a bool that get changed by a checkbox in one of my application.
I am trying to make a automatisation script in Python to change the status of every task a work order that have been check when I save the WorkOrder.
I don't know why it isn't working but I'm pretty sure I'm close to the answer...
Do you have an idea why it isn't working? I know that I have code in comments, I have done a few experimentations...
from psdi.mbo import MboConstants
from psdi.server import MXServer
mxServer = MXServer.getMXServer()
userInfo = mxServer.getUserInfo(user)
mboSet = mxServer.getMboSet("WORKORDER")
#where1 = "wonum = :wonum"
#mboSet .setWhere(where1)
#mboSet.reset()
workorderSet = mboSet.getMbo(0).getMboSet("WOACTIVITY", "STATUS NOT IN ('FERME' , 'ANNULE' , 'COMPLETE' , 'ATTDOC')")
#where2 = "STATUS NOT IN ('FERME' , 'ANNULE' , 'COMPLETE' , 'ATTDOC')"
#workorderSet.setWhere(where2)
if workorderSet.count() > 0:
for x in range(0,workorderSet.count()):
if workorderSet.getString("VDS_COMPLETE") == 1:
workorder = workorderSet.getMbo(x)
workorder.changeStatus("COMPLETE",MXServer.getMXServer().getDate(), u"Script d'automatisation", MboConstants.NOACCESSCHECK)
workorderSet.save()
workorderSet.close()
It looks like your two biggest mistakes here are 1. trying to get your boolean field (VDS_COMPLETE) off the set (meaning off of the collection of records, like the whole table) instead of off of the MBO (meaning an actual record, one entry in the table) and 2. getting your set of data fresh from the database (via that MXServer call) which means using the previously saved data instead of getting your data set from the screen where the pending changes have actually been made (and remember that non-persistent fields do not get saved to the database).
There are some other problems with this script too, like your use of "count()" in your for loop (or even more than once at all) which is an expensive operation, and the way you are currently (though this may be a result of your debugging) not filtering the work order set before grabbing the first work order (meaning you get a random work order from the table) and then doing a dynamic relationship off of that record (instead of using a normal relationship or skipping the relationship altogether and using just a "where" clause), even though that relationship likely already exists.
Here is a Stack Overflow describing in more detail about relationships and "where" clauses in Maximo: Describe relationship in maximo 7.5
This question also has some more information about getting data from the screen versus new from the database: Adding a new row to another table using java in Maximo
No matter how hard I tried I couldn't make it work and I'm not sure if it is possible.
I want to select all clients who have at least one order.
The first thing I tried was db.Exists as following:
SqlExpression<Client> exp = OrmLiteConfig.DialectProvider.SqlExpression<Client>();
exp.Where(x => Db.Exists<Order>(z => z.ClientId == x.Id));
but I get the following error
variable 'x' of type '[assembly].Client' referenced from scope '', but it is not defined`
Second try was using Join and SelectDistinct:
SqlExpression<Client> exp = OrmLiteConfig.DialectProvider.SqlExpression<Client>();
ev.Join<Client, Order>((b, a) => b.Id == a.ClientId)
.SelectDistinct(x => new { x.Id, x.ClientNumber, x.ClientNameName});
Although not optimal it worked, up to the moment when I needed paging for the result set through
ev.Limit(skip:((request.Page-1) * request.PageSize), rows:request.PageSize)
When using Limit the distinct logically get ignored in building the query, so I get now duplicate Clients.
Is there any other way, or in general is there away to handle subqueries in OrmLite?
Any help is appreciated.
ServiceStack OrmLite (currently at 4.0.x) does not have support for subqueries.
If you look at the 4.0.x docs , there is no discussion of subqueries. JOIN support has been added recently, but for advanced SQL, you need to write it yourself.
Honestly, at a certain point of complexity, SQL is more readable than advanced ORM/LINQ-style queries.
I'm just getting started with Subsonic 3.0 ActiveRecord and am trying to implement a batch query like the one in the SubSonic docs. I'm using a batch so I can query a User and a list of the users Orders in one shot.
When I call the BatchQuery.Queue() method, adding my "select user" query, SubSonic throws the following exception:
System.InvalidOperationException : Can't decide which property to consider the Key - you can create one called 'ID' or mark one with SubSonicPrimaryKey attribute
The code is as follows:
var db = new MyDB();
var userQuery = from u in db.Users //gets user by uid
where u.uid == 1
select u;
var provider = ProviderFactory.GetProvider();
var batch = new BatchQuery(provider);
batch.Queue(userQuery); //exception here
//create and add "select users orders" query here...
First things first - Why this error? My SubSonic Users object knows it's PK. "uid" is the PK in the database and the generated code reflects this. And I thought SubSonicPrimaryKey attribute was for the SimpleRepository? Is this way of batching not for ActiveRecord?
I could ask a number of other questions, but I'll leave it at that. If anyone can help me figure out what is going on and how to issue 2 batched queries I'd be grateful!
Edit - after further investigation
I ran through the source code with the debugger. Adam is correct - the ToSchemaTable() method in Objects.cs is apparently building out my schema and failing to find a PK. At the very end, it tries to find a column property named "ID" and flags this as the PK, otherwise it throws the exception. I added a check for "UID" and this works!
Still... I'm confused. I'm admittedly a bit lost after peeling back layer after layer of the source, but it seems like this portion of code is trying to build up a schema for my table and completely ignoring my generated User class - which quite nicely identifies which column/property is the PK! It doesn't seem quite right that I'd be required to name all keys "ID" w/ ActiveRecord.
I think the answer you're looking for is that this is a really stupid bug on my part. I'm hoping to push another build next week and if you could put this on the issue list I'd really appreciate it. My apologies...
SubSonic expects your primary key to be called Id so it's getting confused. SubSonicPrimaryKey is for simple repository but I assume where that exception is being thrown is shared between the different templates. If you rename your PK to Id or id or ID your query will work.
