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;
GO

I'm trying to do a simple incremental update from an on-prem database as source to Azure SQL database based on a varchar column called "RP" in On-Prem database that contains "date+staticdescription" for example: "20210314MetroFactory"
1- I've created a Lookup activity called Lookup1 using a table created in Azure SQL Database and uses this Query
"Select RP from SubsetwatermarkTable"
2- I've created a Copy data activity where the source settings have this Query
"Select * from SourceDevSubsetTable WHERE RP NOT IN '#{activity('Lookup1').output.value}'"
When debugging -- I'm getting the error:
Failure type: User configuration issue
Details: Failure happened on 'Source' side.

Can anyone tell me what I am doing wrong and how to fix it even if it requires creating more activities.
Note: There is no LastModifiedDate column in the table. Also I haven't yet created the StoredProcedure that will update the Lookup table when it is done with the incremental copy.
Steve is right as to why it is failling and the query you need in the Copy Data.
As he says, you want a comma-separated list of quoted values to use in your IN clause.
You can get this more easily though - from your Lookup directly using this query:-
select stuff(
(
select ','''+rp+''''
from subsetwatermarktable
for xml path('')
)
, 1, 1, ''
) as in_clause
The sub-query gets the comma separated list with quotes around each rp-value, but has a spurious comma at the start - the outer query with stuff removes this.
Now tick the First Row Only box on the Lookup and change your Copy Data source query to:
select *
from SourceDevSubsetTable
where rp not in (#{activity('lookup').output.firstRow.in_clause})
The result of #activity('Lookup1').output.value is an array like your error shows
[{"RP":"20210307_1Plant
1KAO"},{"RP":"20210314MetroFactory"},{"RP":"20210312MetroFactory"},{"RP":"20210312MetroFactory"},{"RP":"2'.,Source=.Net
SqlClient Data
Provider,SqlErrorNumber=102,Class=15,ErrorCode=-2146232060,State=1,Errors=[{Class=15,Number=102,State=1,Message=Incorrect

However, your SQL should be like this:Select * from SourceDevSubsetTable WHERE RP NOT IN ('20210307_1Plant 1KAO','20210314MetroFactory',...).
To achieve this in ADF, you need to do something like this:
create three variables like the following screenshot:
loop your result of #activity('Lookup1').output.value and append 'item().RP' to arrayvalues:
expression:#activity('Lookup1').output.value
expression:#concat(variables('apostrophe'),item().RP,variables('apostrophe'))
3.cast arrayvalues to string and add parentheses by Set variable activity
expression:#concat('(',join(variables('arrayvalues'),','),')')
4.copy to your Azure SQL database
expression:Select * from SourceDevSubsetTable WHERE RP NOT IN #{variables('stringvalues')}
I am trying to get the count of all records present in cosmos db in a lookup activity of azure data factory. I need this value to do a comparison with other value activity outputs.
The query I used is SELECT VALUE count(1) from c
When I try to preview the data after inserting this query I get an error saying
One or more errors occurred. Unable to cast object of type
'Newtonsoft.Json.Linq.JValue' to type 'Newtonsoft.Json.Linq.JObject'
as shown in the below image:
snapshot of my azure lookup activity settings
Could someone help me in resolving this error and if this is the limitation of azure data factory how can I get the count of all the rows of the cosmos db document using some other ways inside azure data factory?
I reproduce your issue on my side exactly.
I think the count result can't be mapped as normal JsonObject. As workaround,i think you could just use Azure Function Activity(Inside Azure Function method ,you could use SDK to execute any sql as you want) to output your desired result: {"number":10}.Then bind the Azure Function Activity with other activities in ADF.
Here is contradiction right now:
The query sql outputs a scalar array,not other things like jsonObject,or even jsonstring.
However, ADF Look Up Activity only accepts JObject,not JValue. I can't use any convert built-in function here because the query sql need to be produced with correct syntax anyway. I already submitted a ticket to MS support team,but get no luck with this limitation.
I also tried select count(1) as num from c which works in the cosmos db portal. But it still has limitation because the sql crosses partitions.
So,all i can do here is trying to explain the root cause of issue,but can't change the product behaviours.
2 rough ideas:
1.Try no-partitioned collection to execute above sql to produce json output.
2.If the count is not large,try to query columns from db and loop the result with ForEach Activity.
You can use:
select top 1 column from c order by column desc
I am working on moving stored procedures from an on-prem SQL Server database to an Azure SQL Data Warehouse (ASDW). Throughout the process I have had to work around a few missing features - time consuming but not impossible. One thing I have had to do is replace CTE's followed by MERGE statements with temp tables followed by UPDATE/INSERT/DELETE statements (since CTE's cannot be followed by these statements). At the beginning of each SP I check for the temp tables and delete them if they exist.
Today, I created another stored procedure in the ASDW without any temp tables (no updates/inserts/deletes so I left the CTE's in there), it "compiled", and I was able to run it without issue (returned an empty result set, as there is no data yet). I created another SP after this, and when I went to execute it, I got the following error:
...No catalog entry found for partition ID (id) in database 26. The metadata is inconsistent. Run DBCC CHECKDB to check for a metadata corruption...
I then went back to the first SP that I mentioned, and it gave me the same error, even though it had previously run without flaw.
I tried running DBCC CHECKDB as instructed but alas, it is not supported/doesn't work.
I dug around a lot, and what I ended up doing was scaling my database from 100DWU's to 500DWU's. I am at 0.16% of my database storage size limit, and there is barely any data anywhere (total DB size is <300MB).
Is there an explanation for this? If not, I can't in good conscience use this platform in a production environment.

I'm sorry to hear about your experience with Azure SQL Data Warehouse. I believe this is a defect related to BIT data type handling for NOT NULL columns. Can you confirm that you have a BIT NOT NULL column (e.g., CREATE TABLE t1 (IsTrue BIT NOT NULL);)?
If so, a fix has been coded and is in testing for release. To mitigate this now, you can either switch to a TINY INT or remove the NOT NULL setting for the column.
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.

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"

In My Data Sync Group there have 2 tables . Let say A and B . some columns of A reference to B table. B is Master Table.
When sync occur table A is do the processing ahead of Table B. So I got the Foreign Key Reference Error.
IS Azure Data sync processing with alphabetic order ?
Any solution for this ?
Thz in advance.
As #JuneT suggested, you might want to post this question in the "SQL Azure Forum" (http://aka.ms/sqlazureforum). When you do, they have asked specifically that you include the following information when asking Data Sync related questions:
Server id: Your server id
Region: Where your Data Sync Server is located/created
Time / Date: Date and time when you encountered the issue
Tracing Id: The tracing id you see in the message in UI
