  • And more combinations

2. Function Mapping

  • Date/time functions
  • String functions
  • Math functions
  • Custom function equivalents

3. Syntax Translation

  • String concatenation
  • NULL handling
  • Boolean expressions

4. Performance Hint Conversion

  • Index hints
  • Join hints
  • Optimizer directives
  • Execution plan guidance

5. Query Optimization Suggestions

  • Index recommendations
  • Query restructuring
  • Join optimization
  • Subquery refactoring
