            Write SQL to identify multiple subgroupings within a grouping
            Asked 2021-Jun-12 at 09:57

            I have a program that summarizes non-normalized data in one table and moves it to another and we frequently get a duplicate key violation on the insert due to bad data. I want to create a report for the users to help them identify the cause of the error.

            For example, consider the following contrived simple SQL which summarizes data in the table Companies and inserts it into CompanySum, which has a primary key of State/Zone. In order for the INSERT not to fail, there cannot be more than one distinct combinations of Company/Code for every unique primary key State/Zone combination. If there is, we want the insert to fail so that the data can be corrected.

            How to filter Azure Auditing
            Asked 2021-Jun-08 at 18:21

            I have enabled Azure Auditing in Azure SQL Database, the audit is capturing all activities in the database and store it in Storage Account. My question is, is there away to configure Azure Audit and filter what to capture and not to capture in the audit?

            By default it is capturing DDL, DML, security role, etc and this is tool much information and only wanted to capture security role change, so where do I filter the audit capture as I don't want to filter the data after capture.

            Azure SQL database Auditing doesn't provide the way to customize the audit actives.

            AWS DMS task failing after some time in CDC mode
            Asked 2021-Jun-01 at 05:03

            I'm having trouble in setting up a task migrating the data in a RDS Database (PostgreSQL, engine 10.15) into an S3 bucket in the initial migration + CDC mode. Both endpoints are configured and tested successfully. I have created the task twice, both times it ran a couple of hours at most, the first time the initial dump went fine and some of the incremental dumps took place as well, the second time only the initial dump finished and no incremental dump was performed before the task failed.

            Should anyone get the same error in the future, here is what we were told by the AWS tech specialist:

            There is a known (to AWS) issue with the pglogical plugin. The solution requires using the test_decoding plugin instead.

            1. Enforce using the test_decoding plugin on the DMS Endpoint by specifying pluginName=test_decoding in Extra Connection Attributes
            2. Create a new DMS task using this endpoint (using the old task may cause it to fail due to dissynchronization between the task and the logs)

            It sure did resolve the issue, but we still don't know what the problem really was with the plugin that is strongly suggested everywhere in the DMS documentation (at the moment).

            Automating SQL scripts run into AWS redshift environments (Dev, preprod & prod)
            Asked 2021-May-24 at 14:37

            I wish to automate runs of SQL (DML's and DML's) into the AWS redshift cluster, i.e. as soon as someone merge the SQL file into S3 bucket it should run in the configured environment say dev, preprod & prod. Is there any way I can do this?

            My investigation says that AWS codepipeline is one of the solution however, I am not sure how I will connect to the Redshift database in Codepipeline?

            Another way is using Lambda function but it has its limitation of 5 minutes I guess and some of the DDL/DML might take more than 5 minutes to run.

            There are a lot of choices out there and which is best will depend on many factors including your team's skillset and your budget. I'll let the community weigh in on all the possibilities.

            I would like to advise on using the AWS serverless ecosystem to perform these functions. First off the Lambda limit is now 15 min but this really isn't important. The most important development is Redshift Data API which lets you start queries in a Lambda and for other Lambdas check on completion later. See: https://docs.aws.amazon.com/redshift/latest/mgmt/data-api.html

            With Redshift Data API for fire-and-forget access to Redshift and Step Functions to orchestrate the Lambda functions you can create a low cost, light weight infrastructure to perform all sort of integrations and actions. These can include triggering other tools / services as needed for you. This is not the best approach in all cases but Lambda based solutions should not be excluded due to run time limits.

            How to construct tree pattern matching algorithm in JavaScript?
            Asked 2021-May-18 at 02:36

            Okay this is a bit of an involved question, but tl;dr it's basically how do you parse an "actual tree" using a "pattern tree"? How do you check if a particular tree instance is matched by a specific pattern tree?

            To start, we have the structure of our pattern tree. The pattern tree can generally contain these types of nodes:

            • sequence node: Matches a sequence of items (zero or more).
            • optional node: Matches one or zero items.
            • class node: Delegates to another pattern tree to match.
            • first node: Matches the first child pattern it finds out of a set.
            • interlace node: Matches any of the child patterns in any order.
            • text node: Matches direct text.

            That should be good enough for this question. There are a few more node types, but these are the main ones. Essentially it is like a regular expression or grammar tree.

            We can start with a simple pattern tree:

            The easiest way - just to convert your 'pattern tree' to regexp, and then check text representation of your 'actual tree' with that regexp.

            Regarding the Recursive descent. Recursive descent itself is enough to perform the grammar check, but not very effective, because sometimes you need to check pattern from beginning multiple times. To make single-pass grammar checker you need state machine as well, and that is what Regexp has under the hood.

            So no need to reinvent the wheel, just specify your 'pattern' as regexp (either convert your representation of the pattern to regexp)

            Does creating index in Oracle locks the table for reads?
            Asked 2021-May-14 at 06:15

            If we specify ONLINE in the CREATE INDEX statement, the table isn't locked during creation of the index. Without ONLINE keyword it isn't possible to perform DML operations on the table. But is the SELECT statement possible on the table meanwhile? After reading the description of CREATE INDEX statement it still isn't clear to me.

            I ask about this, because I wonder if it is similar to PostgreSQL or SQL Server:

            • In PostgreSQL writes on the table are not possible, but one can still read the table - see the CREATE INDEX doc > CONCURRENTLY parameter.
            • In SQL Server writes on the table are not possible, and additionally if we create a clustered index reads are also not possible - see the CREATE INDEX doc > ONLINE parameter.
            ...

            ANSWER

            Answered 2021-May-14 at 06:15

            Creating an index does NOT block other users from reading the table. In general, almost no Oracle DDL commands will prevent users from reading tables.

            There are some DDL statements that can cause problems for readers. For example, if you TRUNCATE a table, other users who are in the middle of reading that table may get the error ORA-08103: Object No Longer Exists. But that's a very destructive change that we would expect to cause problems. I recently found a specific type of foreign key constraint that blocked reading the table, but that was likely a rare bug. I've caused a lot of production problems while adding objects, but so far I've never seen adding an index prevent users from reading the table.
