Fixed 3 H2 SQL Errors

Three different SQL queries were causing errors on a H2 database.

Found causes:
- [42001-199] Extra parentheses around subquery: '... FROM (subquery)'
- [HY004 not found] H2 performs query type checks at compile time and
  thus parametized  variables inside SELECT need to be implicitly cast
  to a type

Fixes:
- Removed extra parentheses around 2 queries
- Added a cast to CHAR to a query

Affects issues:
- Fixed #1183
