Fix SQLGetData retrieving data in parts

[trevorbonas]

Summary

Fix SQLGetData retrieving data in parts

Description

• SQLGetData now iterates through variable-length data, as it should.
• SQLGetData varchar tests have been changed to get data in much smaller parts and do a final comparison using a string reconstructed from parts with the full query result.
