SQL Server Compact Edition delete with inner join - sql-server-ce-3.5

Is it possible to use delete with inner join in SQL Server Compact Edition? What is the CE equivalent of this SQL Server query?
delete a from employee a inner join department b
on a.departmentID=b.departmentID where b.departmentStatus='closed'

Find All the tables related to a stored procedure in Azure Synapse Datawarehouse

Is there a simple way to find out all the tables referenced in a stored procedure in azure analytics data warehouse other than parsing the stored procedure code? I tried few commands like sp_tables, sp_depends but none seems to be working in azure data warehouse.

sys.sql_expression_dependencies is supported in Azure Synapse Analytics, dedicated SQL pools, but only supports tables, views and functions at this time. A simple example:
SELECT * FROM sys.sql_expression_dependencies;
So you are left either parsing sys.sql_modules. Something like this is imperfect (ie doesn't deal with schema name, square brackets, partial matches etc) but could server as a starting point:
SELECT
sm.[definition],
OBJECT_SCHEMA_NAME(t.object_id) schemaName,
OBJECT_NAME(t.object_id) tableName
FROM sys.sql_modules sm
CROSS JOIN sys.tables t
WHERE sm.object_id = OBJECT_ID('dbo.usp_test')
AND sm.[definition] Like '%' + t.name + '%';
I actually use SQL Server Data Tools (SSDT) with dedicated SQL pools so your dependencies can't get out of step and are trackable via the project.

MEMSql join with uniouned returns 1899 bad distributed join plan

I have events that are inserted to table game_events and other events that are inserted to table rejected_events.
I want to union them and then do bunch of joins with other data of other tables.
I run this query directly on the memSQL console:
SELECT combinedEvents.*, win.*
FROM (
SELECT event_id, action, status
FROM events.game_events
WHERE event_arrival_time BETWEEN '2019-12-17T00:00:00Z' AND '2019-12-30T23:59:59.999Z'
UNION
SELECT event_id, action,status
FROM rejected.events
WHERE event_arrival_time BETWEEN '2019-12-17T00:00:00Z' AND '2019-12-30T23:59:59.999Z'
) AS combinedEvents
LEFT JOIN winner.winner_data AS win ON combinedEvents.event_id = win.event_id AND win.status = 'ACCEPTED'
I get from mem:
Error Code: 1889. Bad distributed join plan: leaf select contains sharded tables of multiple databases. Please contact technical support.
If I remove the JOIN - It works properly.
Any ideas?
Thanks and best regards,
Ido

It looks like it got solved on the MemSQL Forums and the solution is to move the union to the right of the join.

Why does 'get_json_object' return different results when run in spark and sql tool

I have developed a hive query that uses lateral views and get_json_object to unpack some json. The query works well enough using a jdbc client (dbvisualizer) against a hive database but when run as spark sql from a java application, on the same data, it returns nothing.
I have tracked down the problem to differences in what the function 'get_json_object' returns.
The issue can be illustrated by this type of query
select concat_ws( "|", get_json_object('{"product_offer":[
{"productName":"Plan A"},
{"productName":"Plan B"}]}',
'$.product_offer.productName') )
When run in dbvisualizer against a Hive database I get an array of the 2 product names in the json array: ["Plan A","Plan B"].
When the same query is run as spark sql from a java application, null is returned.
I have noticed another difference: the path '$.product_offer[0].productName' returns 'Plan A' in db visualizer and nothing in spark.

The path to extract the array of product names is
select concat_ws( "|", get_json_object('{"product_offer":[{"productName":"Plan A"},{"productName":"Plan B"}]}', '$.product_offer[*].productName'
which works both in spark dbvisualizer.

Stored Procedure in azure sql database query tables in another azure sql database

I have two azure databases say DB1 and DB2.
DB1 has got few tables and I want to create stored procedure in DB2 to cross query with joins in the tables in DB1. I have seen examples with Cross Database query but mostly showing only single table. My Stored procedure is like:
select
u.UserID as [UserID],
u.Username as [UserName],
u.LastLoginDate,
ISNULL(au.IsDeleted, 1) as [IsDeleted]
from DB1.[sec].[User] u
join DB1.[sec].[AppUser] au on (u.UserID = au.UserID)
join DB1.[sec].[Application] a on (au.ApplicationID = a.ApplicationID)
where (a.Name = 'name')

Just follow the method of this blog post and set up two tables instead of one. It's currently the only way to do a cross database query in Azure SQL Database.

SPARK SQL CREATE VIEW

I have noticed that there seems to be some max length of the create view statement. Below is a SQL query I can run (select statement). If I put a create view in front, it works as long as I limit the columns in the sub-query. The view itself would only contain one column. I have provided this for example. I am running my sql through thrift server. Is there any way to get around this issue? Thanks in advance!

Use JDBC driver included with Spark. I can compile view now. I am using SQL
Use SQL Squirrel instead with JDBC driver to connect and run queries. I was using the Microsoft SPARK ODBC driver. the JDBC one works fine.
