I was working with bw2 on a jupiter notebook. I was successfully linking inventories in excel files with the activity browser.
Today, I cannot open the activity browser user interface anymore & I get this message.
bw2data.backends.peewee.schema.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 ?
I installed the newest update activitybrowser 2.4 but still I get the same message.

I'm working with the Azure Core API. Using the web based data explorer, I'm able to successfully run a query that has multiple aggregations across multiple partitions. Yet when I attempt to run such a query from my shell using the Azure client library for Python (pip install azure-cosmos==4.0.0), I get an error message. I've tried two variations of the query, where one included the partition key and one didn't. Both queries returned the same error message.
container = database.get_container_client('some_container')
query1 = "select c.fmonth, c.fquarter, c.fyear, sum(c.revenue) as actual_revenue__sum, sum(c.predicted_revenue_m1) as predicted_revenue__sum from c where c.fyear=2020 group by c.fmonth, c.fquarter, c.fyear"
query2 = "select c.fmonth, c.fquarter, c.fyear, sum(c.revenue) as actual_revenue__sum, sum(c.predicted_revenue_m1) as predicted_revenue__sum from c where c.date_start >='2020-01-01' and c.date_start < '2021-01-01' group by c.fmonth, c.fquarter, c.fyear"
res = container.query_items(query1, enable_cross_partition_query=True)
Error Message Returned:
CosmosHttpResponseError: (BadRequest) Message: {"Errors":["Cross partition query only supports 'VALUE ' for aggregates."]}
ActivityId: 4961b99e-7032-4eac-ae84-2c8cab03a496, Microsoft.Azure.Documents.Common/2.11.0
Errors out for aggregates on multiple partitions, with enable cross
partition query set to true, but no "value" keyword present
If you want to use aggregates on multiple partitions,select value count(1) from c,this will work.
But python sdk doesn't support group by now.
Refer to this document,.net sdk and js sdk support group by.Other sdk will support later.
Hope this can help you.
I am trying to connect my siddhi application to cassandra data store by following the instructions given in the example program given in the editor.
I downloaded the datastax java jar(Osgi) and placed it in the WSO2/lib folder and now started the application. Now I get an error

Below is the corresponding code
define stream SweetProductionStream (id int, name string);
#Store(type='cassandra' , cassandra.host='localhost' ,keyspace='production')
#index('uid')
#primaryKey('uid')
define table SweetProductionTable (uid int, name string);
/* Inserting event into the cassandra keyspace */
#info(name='query1')
from SweetProductionStream
select SweetProductionStream.id as uid, SweetProductionStream.name
insert into SweetProductionTable;
and below is the instructions given in the example
Prerequisites:
1) Ensure that Cassandra version 3 or above is installed on your machine.
2) Add the DataStax Java driver into {WSO2_SP_HOME}/lib as follows:
a) Download the DataStax Java driver from: http://central.maven.org/maven2/com/datastax/cassandra/cassandra-driver-core/3.3.2/cassandra-driver-core-3.3.2.jar
b) Use the "jartobundle" tool in {WSO2_SP_Home}/bin to extract and convert the above JARs into OSGi bundles.
For Windows: <SP_HOME>/bin/jartobundle.bat <PATH_OF_DOWNLOADED_JAR> <PATH_OF_CONVERTED_JAR>
For Linux: <SP_HOME>/bin/jartobundle.sh <PATH_OF_DOWNLOADED_JAR> <PATH_OF_CONVERTED_JAR>
Note: The driver given in the above link is a OSGi bundled one. Please skip this step if the jar is already OSGi bunbled.
c) Copy the converted bundles to the {WSO2_SP_Home}/lib directory.
3) Create a keyspace named 'production' in Cassanndra store.
4) In the store configuration of this application, replace 'username' and 'password' values with your Cassandra credentials.
5) Save this sample.
Executing the Sample:
1) Start the Siddhi application by clicking on 'Run'.
2) If the Siddhi application starts successfully, the following message is shown on the console
* Store-cassandra.siddhi - Started Successfully!
Note:
If you want to edit this application while it's running, stop the application, make your edits and save the application, and then start it again.
Testing the Sample:
1) Simulate single events:
a) Click on 'Event Simulator' (double arrows on left tab) and click 'Single Simulation'
b) Select 'Store-cassandra' as 'Siddhi App Name' and select 'searchSweetProductionStream' as 'Stream Name'.
c) Provide attribute values, and then click Send.
2) Send at least one event where the name matches a name value in the data you previously inserted into the SweetProductionTable. This will satisfy the 'on' condition of the join query.
3) Optionally, send events to the other corresponding streams to add, delete, update, insert, and search events.
Notes:
- After a change in the store, you can use the search stream to see whether the operation is successful.
- The Primary Key constraint in SweetProductionTable is disabled, because the name cannot be used as a PrimaryKey in a ProductionTable.
- You can use Siddhi functions to create a unique ID for the received events, which can then be used to apply the Primary Key constraint on the data store records. (http://wso2.github.io/siddhi/documentation/siddhi-4.0/#function)
Viewing the Results:
See the output for raw materials on the console. You can use searchSweetProductionStream to check for inserted, deleted, and updated events.
*/
Thanks in advance.
please provide your Cassandra credentials (username and password).
Eg: #store(type='cassandra' , cassandra.host='localhost', username='cassandra', password='cassandra',keyspace='production',
column.family='SweetProductionTable')
Please refer this sample.

When i run the following query in the Azure, I am getting no records. and getting the message "Query succeeded: Affected rows: 0."
1) SELECT * FROM sys.resource_usage where database_name='DB_NAME';
When i run this following query in azure, i get this error , "Failed to execute query. Error: Invalid object name 'sys.resource_stats'."
2) SELECT * FROM sys.resource_st where database_name='DB_NAME';
Please help me solve this issue, as im trying to track the daily database usage i.e amount of data stored in DB.
I suppose the issue is with your current db context, what does SELECT DB_NAME() return? Is that a user database? As per BOL 'This view is available to all user roles with permissions to connect to the virtual master database.' you'd have to connect to the master database before query against both sys.resource_usage and sys.resource_stats.
As Lin mentioned ,You have to connect to Master database to see output of sys.resource_stats
For DBspecific DTU usage , you can use sys.dm_db_resource_stats ..this stores data for every 15 seconds
and your question says
as im trying to track the daily database usage i.e amount of data stored in DB.
you can use below DMV to track that
SELECT sys.objects.name, SUM(reserved_page_count) * 8.0 / 1024
FROM sys.dm_db_partition_stats, sys.objects
WHERE sys.dm_db_partition_stats.object_id = sys.objects.object_id
GROUP BY sys.objects.name;

I created a new table in the Bluemix SQL Database service by uploading a csv (baseball.csv) and took the default table name of "baseball".
I created a simple app in Node.js which is just trying to select data from the table with select * from baseball, but I keep getting the following error:
[IBM][CLI Driver][DB2/NT] SQL0204N "USERxxxx.BASEBALL" in an undefined name
Why can't it find my database table?
This issue seems independent of bluemix, rather it is usage error.
This error is possibly caused by following:
The object identified by name is not defined in the database.
User response
Ensure that the object name (including any required qualifiers) is correctly specified in the SQL statement and it exists.
try running "list tables" from command prompt to check if your table spelling is correct or not.
http://www-01.ibm.com/support/knowledgecenter/SSEPGG_9.7.0/com.ibm.db2.luw.messages.sql.doc/doc/msql00204n.html?cp=SSEPGG_9.7.0%2F2-6-27-0-130
I created the table from SQL Database web UI in bluemix and took the default name of baseball. It looks like this creates a case-sensitive table name.
Unfortunately for me, the sql_db libary (and all db2 clients I believe) auto-capitalizes the SQL query into "SELECT * FROM BASEBALL"
The solution was to either
A. Explicitly name my table BASEBALL in the web UI; or
B. Modify my sql query by quoting the table name:
select * from "baseball"
