Redgate SQL Data Generator -> Reviewing sqlgen project -> What does “Same as mapped data” mean?

Question

I am reviewing a coworkers sqlgen job and I am unable to figure out what this means in the table generation settings.

Specify number of rows by: "Same as mapped data"

My coworker has this selected on each table, I just need to know what is meant by this I have looked through documentation and been unable to find a definition for this.

I am on version 2 at the moment. Probably not the best question but I need an answer and he is gone for a long period of time and our data is not working correctly with this tool.

Answer 1

The "Same as mapped data" option is only available when you're using an existing table or view as a data source - it just means that the generator will insert all the rows from the source table or view. The other options are:

• Numeric value - a set number of rows
• Proportion of table - a proportion of the source table/view
• Generation time - as much data as the tool can generate in a set time

There's a little more about using an existing table/view as a data source here on the website, but it doesn't have much else useful in it.
