Robot Framework data-driven automation testing: Can data derived from a database be used as a data source for a test template?

Question

I am familiar with using template keywords in data-driven Robot Framework testing and know that external sources of data such as text files and csv files can be used to provide test data. However, the organisation I work for wants to use data held in a database as a source for test case data. Does anybody know if this is possible? I have searched Stack Exchange and other resources but cannot find an answer or any examples.

Here is an example of the data-driven approach I am familiar just to give you an idea of where we are now.

Since this question was cross-posted to stackoverflow, I'll cross-post my answer:

Unfortunately, the use of test templates more-or-less require that the data is hard-coded in the test case. However, the test template is not much more than a wrapper around a for loop. You could do something like this:

| | ${database_rows}= | Run sql query
| | ... | Select * from the_database where ...
| | 
| | :FOR | ${row} | IN | @{database_rows}
| | | Suspend Region | @{row}

Of course, this requires that you write the "Run sql query" keyword or an equivalent to fetch the data.

The downside of this is that all of the permutations are considered a single test case with multiple keywords, versus multiple test cases with a single keyword.

If you want to have one test case per row in a database, you could write a script that does the query, generates a test suite file using the results of the query, and then runs pybot on the generated file.
