Hi @sr.kancham While I am not sure what SSDT means and what is used for, with regard to how to use dynamically passed values to a changelog/changeset, here is something that could help: > **[Substituting Properties in Changelogs](https://docs.liquibase.com/concepts/changelogs/property-substitution.html?Highlight=token)** > > Liquibase allows dynamic substitution of properties in your changelog. The tokens to replace in your changelog are described using the ${property-name} syntax. Also, on the same topic, asked here: > [@Passing Runtime Variables to SQL files](https://forum.liquibase.org/t/passing-runtime-variables-to-sql-files/4331): > > Hello All, We have recently started using Liquibase, I would like to know if it is possible to pass runtime variables to SQL scripts in Liquibase. For examples I have &schema\_name in my script, can I store this value in the properties file and call it out during the script execution. So in few words, you would need to have the changelog/changeset contain the pattern ${databaseName} where needed, as a token (in your example, preceeding the dbo schema) and this token’s value can be set, as a parameter/value at runtime in the liquibase command: ` liquibase ... -DdatabaseName=` … Hope this helps, Eduard --- _[View the full topic](https://forum.liquibase.org/t/how-to-refer-objects-from-another-database/7017)._
