Source: SQL Server 2008 R2
Destination: Azure SQL Database in an elastic pool
I am migrating multiple databases from source to destination using offline DMS. While migrating these databases some stored procedures are giving errors because of three-part and four-part entries in the stored procedure. for this, I am using external tables to convert it into two-part. but some stored procedures are used for DML commands like insert and update. I want to know how I can convert this DML commands stored procedure in elastic query.
As a limitation mentioned in this doc, Migrating to a DB in elastic pool directly isn't supported. But you can import data into a single database and then move the database to an elastic pool. Once you have it in same Logical Server. Move the DB under Elastic Pool.
Refer similar ask here or the official MS doc to do this using the Portal
Instead you can also initiate replication from a snapshot or through BULK Load.

We have a production postgresql db available only in glue catalog. What's the best practices to ETL some tables in this database and load the data into another postgresql instance in the same aws account?
This production database is our transactional db and we don't need most of it's tables. We already have some glue ETL's creating tables in S3 (so accessible via Athena) but the goal here is to load into another postgresql instance.
Thanks
To improve the read performance, we are synching RDS Postgresql data to AWS ElasticSearch. Used AWS DMS for it. It's working fine. But Joining tables is a challenge. We need a solution to denormalize the data and put it in elastic search using AWS DMS. For example, In customer and order tables in PostgreSQL should be one record in ElasticSearch.
I’m trying to perform a Diff on two DB2 schema’s and when I try to select my source and destination connections it doesn’t list my NEW connection. I’m using latest version. I can connect to DB2 manually and query as well, but just can’t sect that connection during database Diff.
Where are the connections saved in sql
Developer?
That feature is reserved for Oracle Database connections.
DB2 connectivity is provided for migrations to Oracle only.
We have limited support for DB2 in the Data Modeler (which is part of SQL Developer), and you can compare models, but the generation of DDL synch scripts is reserved for Oracle data models only.
I have a db2 database on a device which does not have internect connectivity and would like to move this database to another place. I have taken a backup from my database, can I use the 'restore' command to create a clone of this database?
To move a Db2 database from on-premise to Db2 Warehouse on Cloud, one option is to use IBM Lift CLI. https://www.lift-cli.cloud.ibm.com/
You will need to have internet connectivity from the place your data resides on-premise - either a Db2 database, or failing that CSV files.
If all you have is a Db2 backup image, you would need to restore that into a local database, or use the (chargeable) utility High Performance Unload to extract table data as CSV files from the backup image. IBM Lift CLI does not support Db2 backup images as a source for migration to the cloud.
Note that if you use CSV files, you will need to extract the DDL from the source database and create the empty tables on the target.
Is there a way to backup or restore a specific schema or table on a Cloud SQL server? Backing up the entire set of data, but then being able to restore only certain schemas or tables would be very helpful for multi-tenant systems.
Not via backup/restore. You can export a specific schema or table to Google Cloud Storage, but that's probably not what you're looking for.
The Cloud SQL use MySQL database with some limitations. You can check out the unsupported features and functions at the following link:
https://cloud.google.com/sql/faq#supportmysqlfeatures
With this in mind any backup/restore tool that are being used for MySQL should work for Google Cloud SQL as well. Using mysqldump for import/export of Cloud SQL is covered at this document:
https://cloud.google.com/sql/docs/import-export
You can use mysqldump to backup specific table or backup entire database and restore only specific tables using the solutions offered in these links:
Can I restore a single table from a full mysql mysqldump file?
How to take backup of a single table in a MySQL database?
You can restore the backup to a different instance and then replace the data on the original instance with the data from the backup instance.
