在同一转换 ETL 中更改数据源

Question

I have a transformation to extract data for a database but the database source has many tables with different names. The database does have a structure consistent with my transformation, eg: Events_1, Events_2, Events_3.

It possible change the connection parameters for the extraction of all tables dynamically? I want to extract all data with just one job that will still work when there is a new insert or a new table like Events_600.

You can use variables in the transformation and use them to set the connection and even to change the source table.

You will need a job to run through the list of variable values, then once for each row pass those values as parameters to the transformation, for example.
