1. Which information should accompany an AI request to translate a query between SQL dialects?
   • The source query alone, without either schema
   • Only the destination engine and the current row count
   • Both engines and versions, relevant schema and expected results
   • Only the source execution plan, without expected results
2. Why does a query working on a flexibly typed SQLite table not prove it will work under the destination schema?
   • The destination may enforce different type and conversion rules
   • SQLite column affinity guarantees identical type enforcement in every engine
   • A query accepting a value locally proves it is valid for the target column
   • Column type declarations eliminate all engine-specific conversions
3. A report returns the first ten rows without a defined order. What must be clarified before comparing its ordered results across engines?
   • Whether both queries specify the same limit, regardless of order
   • Whether the current storage layout happens to return matching rows
   • Whether the engines initially show the same first ten rows once
   • The intended deterministic ordering and top-set selection
4. In PostgreSQL, which distinction should a translator preserve between double and single quotes?
   • Both forms always denote ordinary string literals
   • Double quotes delimit identifiers; single quotes delimit ordinary string literals
   • Double quotes are only for numeric values
   • Single quotes preserve identifier case in every reference
5. Two translated queries display similar values. Which additional comparison can expose a meaningful difference?
   • Only whether both results contain the same total number of rows
   • Only whether a few sampled displayed cells match
   • Row membership, duplicate counts and resulting data types
   • Only whether both statements execute without a syntax error
6. Why should parameter placeholder syntax be checked against the target driver as well as the database?
   • Binding conventions also depend on the client API
   • Every database driver uses the same placeholder format
   • Parameterization must always be removed during migration
   • Placeholder names determine the query's output sort order
7. The converted SQL parses successfully. Which claim still requires execution evidence?
   • That the destination recognizes its syntax
   • That the statement was accepted by the parser
   • That the query can be examined in a test environment
   • That it preserves the source query's intended results
8. After establishing that source and destination results agree, which concern should be measured separately?
   • Whether result equivalence can be assumed without fixtures
   • Performance and the destination's execution strategy
   • Whether testing can replace the intended business meaning
   • Whether all destination indexes must match source index names
