fix: invalid usage of IQueryBuilder::createNamedParameter()

[st3iny]

• Followup to: #47832

Summary

I'm sorry, I missed some issues during my code review.

1. Creating a parameter without a value is done via IQueryBuilder::createParameter().
2. Fixed a small typo.
3. Fixed inconsistent and missing types for parameters to improve compatibility with oci.

He, can we cancel the back ports of this? I was just going to adjust the original backports.

I'd say no. For consistency it is better to merge the other backports and then backport this PR.
