I've got to say - when the OP was asking for an example I was also hoping to see an example as a respondent. The StringUtils page doesn't have a very good demonstration of read/write/store - just an example of the syntax. It's quite difficult to understand as someone entering programming.
Dim table1 As List
table1 = DBUtils.ExecuteMemoryTable(SQL1, "SELECT * FROM yourtable", Null, 0)
Dim si As StringUtils
si.SaveCSV(yourdir, "yourfilename.csv", ";", table1)
table1.Clear
