adapters: use dataframes instead of sql strings#6245
Merged
Conversation
This was prompted by an errornous SQL injection report. While those arent really security vulnerabilities here because there is no point where this can get injected by an untrusted source, it still seemed more ergonomic to transform this into data-frame API calls when looking at it. I think it also enhances error reporting in some cases. Adds a few more tests. Signed-off-by: Gerd Zellweger <mail@gerdzellweger.com>

PR #6245 caused a regression for `cdc_order_by` which prevented parsing of order by clauses with multiple fields. That was because we didn't use the right DF function to parse it. This corrects the mistakes and adds a series of tests. Signed-off-by: Gerd Zellweger <mail@gerdzellweger.com>

This was prompted by some invalid SQL injection reporter.
While nothing here exposed a real "sql injection" (because there is no point where an untrusted source can write a connector config), it still seemed more ergonomic to transform this into the data-frame API when looking at it.
I think it also enhances error reporting in some cases. The PR adds a few more tests.
