You want two loops: one for the rows in the main table, then one for each entry to be made for the row.

QUESTION

Merge in Snowflake- Not matched ,Update and Insert

Asked 2022-Mar-21 at 08:00

I have two tables as below.

Source table:

ID EventDate Updated_at metre Active_flag 1004 2022-03-10 2022-03-15 13 Y 1005 2022-03-18 2022-03-18 50 Y 1006 2022-03-15 2022-03-15 10 Y 1007 2022-03-20 2022-03-20 1 Y

Target table:

ID EventDate Updated_at metre Active_flag 1001 2022-01-01 2022-01-01 10 Y 1002 2022-01-02 2022-01-02 15 Y 1003 2022-03-01 2022-03-01 20 Y 1004 2022-03-10 2022-03-10 10 N 1004 2022-03-10 2022-03-15 13 Y 1005 2022-03-18 2022-03-18 5 Y

I need to do the Update and Insert (NOT DELETE) to the Target table for the Date>='2022-03-01'. The comparison should be based on ID and Updated_at. These are the fields coming from API.

Case 1: I need to Update Active_flag in Target Table when the record is not in Source. In this example is, ID= 1003 (as the other records don't meet the Date range filter) should be updated to Active_flage='N'. ID=1004 and Updated_as=2022-03-10 are not matching, and in Target table should have Active_flag='N'(which already has).

Case 2: If they match ID and Updated_at, I can leave them as it is.(Like ID=1004 and updated_at=2022-03-15 Or ID=1005 and Updatyed_at=2022-03-18).

Case 3: If they don't match and the ID is not in Target, I want the records to be INSERTED. Like ID=1006 and ID=1007.

The desired Target table after the Merge should be:

ID EventDate Updated_at metre Active_flag 1001 2022-01-01 2022-01-01 10 Y 1002 2022-01-02 2022-01-02 15 Y 1003 2022-03-01 2022-03-01 20 N 1004 2022-03-10 2022-03-10 10 N 1004 2022-03-10 2022-03-15 13 Y 1005 2022-03-15 2022-03-15 5 Y 1006 2022-03-15 2022-03-15 10 Y 1007 2022-03-20 2022-03-20 1 Y

My question: I could achieve that by using Left and right joins and using two different Tasks in Snowflake, but I just wanted to know if I can achieve that by using MERGE in Snowflake in one Task?

QUESTION

Why is cx_Oracle performing better than PHP OCI8?

Asked 2022-Jan-09 at 22:27

I am trying to determine why a query that returns CLOB data runs so much faster using python3 and cx_Oracle in comparison to PHP 7.4 with OCI8.

Oracle Client Libraries version is 19.5.0.0.0. Queries are ran on the same client and against the same database using the same user. See below for the test PHP and Python scripts. The PHP script takes about 16 seconds or so to retrieve the result set of 220 rows. The Python script takes all of 0.2 seconds to run and print the result set to the console. Is there some kind of client side caching occurring with the python cx_Oracle package? Or is the difference in the outputtypehandler to retrieve the CLOB as a string compared to how the PHP extension retrieves it as a string? Possibly the cx_Oracle package takes advantage of the LOB prefetching with Oracle 12.2 and greater?

...

ANSWER

Answered 2022-Jan-09 at 22:27

A big difference is the output type handler in the Python example. (But note that this will only allow LOBS up to 1GB to be fetched). This is much more efficient than the internal fetching of Oracle LOB locators that happens without the Python type handler, or happens in PHP OCI8. Locators are like pointers. With locators there is the need for extra round-trips between the app and the DB to get the actual LOB data. This is mentioned in the cx_Oracle doc and in the example return_lobs_as_strings.py.

Another difference is that cx_Oracle supports row array fetching (getting multiple rows each time an access to the DB is made), whereas PHP OCI8 only has row prefetching - which doesn't work with LOBs. Fetching each row in PHP (if it contains a LOB or LONG) requires a separate round trip to the database.

With PHP OCI8 3.2 from PECL for PHP 8.1, or with the bundled OCI8 in the PHP 8.2 development branch, you can enable LOB prefetching which can give a nice boost for PHP OCI8 when dealing with non-huge LOBS. This can remove round-trips to get data from each locator. However you can't overcome the lack of array fetching in PHP OCI8.

Some snippets to count round-trips in PHP are:

Run update on multiple tables in BigQuery

Asked 2021-Aug-31 at 07:58

I have lake dataset which take data from a OLTP system, with the nature of transactions we have lot of updates the next day, so to keep track of the latest record we are using active_flag = '1'. We also created a update script which retires old records and updates active_flag = '0'.

Now the main question: how can i execute a update statement by changing table name automatically(programmatically). I know we have a option of using cloudfunctions but it'll expire in 9 mins and I have atleast 350 tables to update. Has anyone faced this situation earlier??

...

ANSWER

Answered 2021-Aug-31 at 07:58

You can easily do this with Cloud Workflows.

There you setup the template calls to Bigquery as a substeps, and then you pass a list of tables, and loop through the items and invoke the BigQuery step for each item/table.

I wrote an article with samples that you can adapt: Automate the execution of BigQuery queries with Cloud Workflows
