Thanks @etgarperets! The changes look good to me overall, left some minor comments

[ODBC escaping sequence]
Can we include a doc link referencing this part of the comment?

| let sql_d = "SELECT {d '2025-07-17'}, category_name FROM categories"; |

Could we include a negative test for an expression that doesn't use the expected character? e.g. SELECT {tt '14:12:01'} FROM foo

I think this branch could be simplified to something like above?

here's one example of how we do negative tests, can we rewrite to use that pattern instead of the should_panic macro? Also we can inline the scenario into the test_odbc_time_date_timestamp_support function since they belong to the same feature

@etgarperets could you take a look at resolving the conflicts on the branch when you get the chance? |
…timestamp literals. For this I modified TypedString by adding uses_odbc_syntax flag.
