To a table that looks like: create table a(id int, another_column varchar(12)) ![]() The SSDT way (and redgate sql compare way) to do a deloyment is to declare what you want so if you want to change a table that looks like: create table a(id int) With SSDT you have the development environment so you get things like go to definition, find references and intelli-sense as well as the ability to compile a project into a dacpac and then deploy that dacpac to a database. SSDT is comparable to Liquibase/Flyway as it does what they do but by taking a different approach.
