I have 4 source SQL queries which is pointing different db's in the same server. All 4 queries results need to stored in single SQLServer table of different server. which one is best approach mentioned in below ?
1) Writing SP using union all option with all four source queries and use this sp in single data flow task[single source and destination tasks].
2) 4 source tasks to execute the 4 sql queries and then use Union all transformation to club the result and then one destination.
3) 4 different data flow task. Each data flow task point the different souurce queries and the same destination.
Please suggest in all aspects.
