what connection is taken at runtime in SSIS -


1) have ssis package , using package parameter configure connections point dev. db . if use environment variables pass different connection value pointing test, after deploy ssis catalog , further schedule using sql agent job. connection info. taken @ runtime , when job scheduled run. dev or test conn?? 2) have ssis package , using project parameter configure connections point dev. db . if use environment variables pass different connection value pointing test, after deploy ssis catalog , further schedule using sql agent job. connection info. taken @ runtime , when job scheduled run. dev or test conn??

answer on first question depends on whether using ssis package configurations or not. possibly not, since talking environment variables, if still , use environment variables - see microsoft article on that, , note behavior changes ssis 2008 version.
if using ssis catalog , package/project variables, mind simple rule - more specific wins. in case, following precedence take place, going next value if former missing:

  1. value specified @ package start, either execution or dtexec parameters.
  2. value mapped environment variable.
  3. vales specified @ package design time.

here microsoft article on package parameter value mapping.
