Para tornar o despejo em um sistema de controle de código-fonte um pouco mais rápido, você pode ver quais objetos foram alterados desde a última vez usando as informações da versão em sysobjects.
Configuração: crie uma tabela em cada banco de dados que você deseja verificar incrementalmente para reter as informações da versão da última vez que você as verificou (vazia na primeira execução). Limpe esta tabela se desejar verificar novamente toda a estrutura de dados.
IF ISNULL(OBJECT_ID('last_run_sysversions'), 0) <> 0 DROP TABLE last_run_sysversions
CREATE TABLE last_run_sysversions (
name varchar(128),
id int, base_schema_ver int,
schema_ver int,
type char(2)
)
Modo de execução normal: você pode pegar os resultados desse sql e gerar scripts sql apenas para os interessados, e colocá-los no controle de origem de sua escolha.

Nota: Se você usar um agrupamento não padrão em qualquer um dos seus bancos de dados, será necessário substituí-lo /* COLLATE */pelo agrupamento do banco de dados. ieCOLLATE Latin1_General_CI_AI
