Generate All scripts with Create and Alter statements for Table in SQL Server?

Question

I want to generate all scripts in my database. As you know, clicking "Generate Scripts", it outputs all tables, all stored procedures etc. with CREATE statements.

How can I get an ALTER statement for recently changed tables and CREATE statement for recently added tables, at the same time?

As an example, A, B, C, D tables were created before. Then I add a new table as E and I changed a column name in C. When I click "Generate Scripts", it must output:

IF NOT EXISTS ....
CREATE TABLE A
....

IF NOT EXISTS ....
CREATE TABLE B
....

IF NOT EXISTS ....
CREATE TABLE C
....

IF NOT EXISTS ....
CREATE TABLE D
....

IF NOT EXISTS ....
CREATE TABLE E
....

ALTER TABLE C
MODIFY COLUMN XX...

like this.

Answer 1

Generate Scripts will just give you the create statements for the various objects in your database. It sounds like you're looking for a source control system, which would be able to generate CREATE/ALTER statements depending on changes from what is in source control.

Answer 2

Use SSMS to generate your scripts into a new query window, then in SSMS in that new query window do a find and replace using a RegEx search.

So if your script contains Functions click Ctrl+H then:

Search item: (create.*function)

Replacement item: create or alter function

Then replace as needed
