Is there anything similar to global variable in SSIS? I have 4 variables (FromAddress, ToAddress,…) which will be used in all packages (32).
So if I can set them only once it will be very easy to use in all packages and will save my time.
Please advise.
SSIS has variables that can be global to a package, but to span multiple packages, I can think of the following options
Passsing Variables
Have Main Package define a variable and pass the value as a parameter to all packages that it calls. Call the variable the same name in all packages for easy identification.
Config File
Use the same SSIS configuration file across packages and store the value in there.
Environment Variable
Use a windows environment variable that is read from other packages
Registry Value
Store in Windows registry and read for each package – make sure you store under a tree that all packages can see otherwise you may run into permissions issues. Eg HKLM
Database Lookup
Store the value a table structure.
