Create statements dinamically using list methods

[lucasp0r]

Changelog

• Simplify thousands of grants to run.
• Example Terraform execution

Note: @aidanmelen The idea is to keep in a list of execution if you have a large environment in my case, I have had 1k grants to run. So that's why I'm using this method. It's working really well :). Thx for your support and help in this provider creation.

Thank you for you input. I think it is really cool what you have accomplished with the for loop here! However, I am going to close this in favor of the new update statements feature for in-place updates. Please see this discussion for more information.

Hopefully this new change with simplify your snowsql grant statements in terraform! I was thinking you could experiment with something like this:

locals {
  create_or_update_statements = join(
    "",
    flatten(
      [
        for id,db in snowflake_table_grant.update_db_future : formatlist("GRANT UPDATE, INSERT, DELETE, TRUNCATE ON ALL TABLES IN DATABASE ${db.database_name} TO ROLE %s;", db.roles)
      ]
    )
  )
  update_grant_all_schema = join(
    "",
    flatten(
      [
        for id,db in snowflake_table_grant.update_schema_future : formatlist("GRANT UPDATE, INSERT, DELETE, TRUNCATE ON ALL TABLES IN SCHEMA ${db.database_name}.${db.schema_name} TO ROLE %s;", db.roles)
      ]
    )
  )
}

resource "snowsql_exec" "my_grants" {
  name = "my_grants"

  create {
    statements = local.create_or_update_statements
  }

  update {
    statements = local.create_or_update_statements
  }

  delete {
    statements  = "REVOKE SELECT PRIVILEGES ON ALL MATERIALIZED VIEWS IN DATABASE TEST TO ROLE TEST;"
  }

  lifecycle {
    ignore_changes = [
      create,
    ]
  }
}
