kandi X-RAY | DWH Summary
Simple (but working) WEP/WPA/WPA2 Hacking script. The tool is semi-automatic, so you have to give him the input and explicit your preferences and it will do the rest. There are different ways to crack the password, and all of them concern external tools. and it is necessary the unix terminal emulator "xterm". If you use an operating system aimed to computer security, like Kali linux or BugTraq, then you will find almost all of them, probably execpt for Hascat.

QUESTION
i'm working with Snowflake, i created this Stored Procedure, it's purpose is to do the following steps:
- extract the relevant 'application_id' values from the SQL query
- use a FOR loop over a SQL query, with the 'application_id' values that i extracted in step 1, and delete the relevant rows from the target table.
when i call the Stored Procedure, it runs without errors, but it doesn't do anything ( the relevant records are not been deleted).
i added my SP code, please let me know if you see any syntax / logic errors, thanks

Answered 2022-Mar-01 at 14:19Are you sure your query is returning data? Also are you sure the target table has data matching your DELETE statement?
The following test works for me using your stored procedure:

QUESTION
I have the problem that in our Snowflake DWH views were built on of top views (& again on top of views). If am now trying to change the underlying table the first view is derived from, I am afraid to break things.
Heres an example:
We have a table with REGISTRATIONS
for several countries. Based on that table a view is created only showing data from US (REGISTRATIONS_US
). This view is being used to built a view containing US data from lets say 2021 (REGISTRATIONS_US_2021
). This view is again being used to build a view containing data from US in 2021 for a specific month, lets say July (REGISTRATIONS_US_202106
). It can also happen that a view is used to generate more than one view (see for example REGISTRATIONS_US_NYC
in the table provided below).
If I would now change the registrations table all the related views are affected. Therefore I need to find out how the views are related.
The only information I have is the one available in INFORMATION_SCHEMA
:
SELECT * FROM REGISTRATIONS WHERE market = 'US' REGISTRATIONS_US_2021 CREATE VIEW REGISTRATIONS_US_2021 AS
SELECT * FROM REGISTRATIONS_US WHERE year = 2021 REGISTRATIONS_US_202106 CREATE VIEW REGISTRATIONS_US_202106 AS
SELECT * FROM REGISTRATIONS_US_2021 WHERE month_id = '202106' REGISTRATIONS_US_NYC CREATE VIEW REGISTRATIONS_US_NYC AS
SELECT * FROM REGISTRATIONS_US WHERE city = 'NYC'
I would like to gain the following solution:
LINEAGE REGISTRATIONS_US > REGISTRATIONS_US_NYC REGISTRATIONS_US > REGISTRATIONS_US_2021 > REGISTRATIONS_US_202106I guess that should be somehow possible using a recursive CTE. But I just cannot imagine how since most examples of recursive CTEs to be found on Google already show the hierarchy in the table based on ids (typical manager/ employee example).
I hope my question is clear & someone can help.

Returns a list of objects that a specified object references. Input is currently limited to the name of a view.

.nodes('/foo')

QUESTION
I have many times implemented slowly changing dimensions on DWH's in batch whereby a set of changes greater than 1, for a given business key, can be processed. No sweat.
Using following:
- Spark non-Structured Streaming Programs
- ETL tools
- PL/SQL
However, using Structured Streaming this is not possible as far as I can see due to multi-step nature and the limitations that prevail with Spark Structured Streaming.
Or is this possible? If so, please advise if there is a method?
...ANSWER
Answered 2022-Jan-15 at 20:37Yes, it's possible, but you need to have some code to implement it. From your update dataframe you need to create a union of:
- updates themselves, that will have a full merge key - they will match you'll set
current = false
andend_date = date_of_new_record
- a result of inner join with the target table, but setting the merge key(s) to NULL, so they will not match & will be inserted as new rows with
current = true
andend_date = null
Code is from official documentation (and notebook):

QUESTION
I am a newbie to SSIS and trying to replicate the current ELT process (which is configured via a set of store procedures) using SSIS.
The ELT process: I have a config table that has all the table information stored. The key column in this table is called 'Active'. This allows me to enable and deactivate tables that I don't want the ELT to run at any given time. The ELT_SP scans the DWH_Process table for tables marked as active and thereafter executes the schedule for that specific job via server agent.
The SSIS Process I have configured the SSIS packages to extract data from the CRMs and import into DWH. I have used the 'sequence containers' control flow to replicate the ELT process, and this is working perfectly.
The problem is, I would then have to update 300+ tables and redeploy to the DWH.
In SSIS, what other options are available to me, and is there a simpler way to add in the 'check active status' before executing the package through a job agent?
...ANSWER
Answered 2022-Jan-13 at 09:41A setup I've used in the past is something like this:
- Setup a table with the configuration, something with columns like PackageName, IsEnabled, Partition ...
- Create a loop package, that you are going to call in the root packages. The loop package queries, the config table based on a parameter of the package (e.g. Partition=1) , for a specific partition. The query also filters on IsEnabled = 1 or a different condition for your case. After the query you starts a foreach loop for every result/package that's returned from the query. This foreach then calls the actual package with your logic. You use a variable from the foreach to start the
Execute package task
- Create a root package
- In a sequence container in the root package, add N execute package tasks that calls the loop package, where you pass a parameter which partition they are executing. (This is purely for performance to run multiple packages at once.)
The benefit of this approach is you can enabled disable packages with a simple update statement, no need to redeploy. You can play with the partitions to get the best performance.

Answered 2021-Dec-28 at 15:28Maybe this will help understand one approach to applying a set of replacement patterns to your target table in an UPDATE
statement.
Just to clarify, REPLACE
will replace all the matched occurrences in a string, as seen in the last example string... '6this is XYZ another XYZ test'
is updated to '6this is another test'
.
From the t-sql documentation:
REPLACE (Transact-SQL)
Replaces all occurrences of a specified string value with another string value.

Answered 2021-Dec-24 at 14:02Confused by your question, is it that you want to get the details of the file or folder from the get metadata activity? Or do you want to enumerate/store the child items of a root folder?
If you simply want to reference the items from Get Metadata, add a dynamic expression that navigates the output value to the JSON property you seek. For example:
