How to use this step

You can create an input step from a database of your choice and then create an input hop to this step.

You may choose to create inputs from two different databases which *should* have the same structure and use a "Merge rows (diff)" step to compare the structure.  If doing this, note that the case of field names are sometimes different and that the data types are also detected differently from different database engines.   It may help to sort the result by "position" to help identify where a column mismatch causes a "new" and "deleted" record.
