Flyway and SSDT: Extracting a DACPAC from a Flyway-managed Database

When you are integrating Flyway into an existing SQL Server SSDT development, you don't necessarily have to change everything at once. The development team might continue to use the SSDT tools, but Flyway will soon take over the deployments. This means that any automated processes will need to be able to handle both DACPACs and Flyway migration scripts with equal grace. In this article, I'll demonstrate how to automatically extract a versioned DACPAC from each new Flyway version of a database.

Retrieving MySQL data from within Python

The approach you take when accessing MySQL will depend on the programming language you’re using and the connector you choose for interfacing with the database. Whatever approach you take, the same basic principles generally apply to each environment. You must establish a connection to the database and then issue the commands necessary to retrieve or modify the data.

Question of the Day

Comparing Images

I am building an ETL process between these tables in SQL Server 2022 set to 160 compatibility level:

CREATE TABLE Image_Staging
( imageid     INT NOT NULL CONSTRAINT Image_StagingPK PRIMARY KEY
, imagestatus TINYINT
, imagebinary IMAGE);
GO

CREATE TABLE Images
( imageid       INT NOT NULL CONSTRAINT ImagesPK PRIMARY KEY
, imagestatus   TINYINT
, imagemodified DATETIME
, imagebinary   IMAGE);
GO
I want to run this query to check if the images already loaded exist. This will help me decide if I need to insert or update an image. What happens with this query?
SELECT i.imageid
FROM
  dbo.Image_Staging AS ist
  INNER JOIN dbo.Images AS i
    ON ist.imagebinary = i.imagebinary;
