ODBC conformance:\nDo ODBC conformance levels specify which SQL statements, expressions, functions, and data types a driver can process?

Introduction / Context:
ODBC drivers advertise conformance so application developers can predict which parts of the ODBC API and SQL grammar will work reliably. This question tests recognition of what conformance levels actually describe.

Given Data / Assumptions:

• Drivers vary in SQL grammar, scalar functions, and data type support.
• Conformance levels (historically Core, Level 1, Level 2, plus function/type sets) document supported features.
• Applications may adapt based on reported capabilities.

Concept / Approach:
ODBC conformance levels outline feature sets across APIs and SQL. They tell you whether a driver supports certain statements (e.g., outer joins via escape syntax), functions (string/date/math), and types (date/time/timestamp, Unicode). Therefore, they do specify statements, expressions, and data types a driver can process.

Step-by-Step Solution:
Query driver capabilities (SQLGetInfo/SQLGetFunctions).Match required features to the driver’s conformance level.Guard or adapt application code paths accordingly.

Verification / Alternative check:
Tools and drivers expose capability matrices; attempting unsupported features results in errors, confirming the practical meaning of conformance.

Why Other Options Are Wrong:
Limiting this to a single SQL edition or tying it to DSN type misconstrues conformance, which is driver/feature-based.

Common Pitfalls:
Assuming high conformance implies identical behavior across vendors; subtle differences may remain.

Final Answer:
Correct
