In Microsoft SQL Server, the clause FOR XML RAW in a SELECT statement instructs the engine to produce XML in what structure?

Difficulty: Easy

Correct Answer: Place the values of the columns as attributes in each XML row element.

Explanation:


Introduction / Context:
SQL Server supports several FOR XML modes (RAW, AUTO, PATH) to serialize result sets into XML. Understanding their output shape is important for integration and APIs.



Given Data / Assumptions:

  • We are using FOR XML RAW.
  • Default behavior (without additional options) is considered.


Concept / Approach:
FOR XML RAW returns each row as a generic element (often ) with each column serialized as an attribute on that element, unless directives alter behavior.



Step-by-Step Solution:

Recall RAW mode: one element per row; columns as attributes.Match this to the choices provided.Select option (a).


Verification / Alternative check:
Run a simple query like SELECT 1 AS A, 'X' AS B FOR XML RAW; the output resembles .



Why Other Options Are Wrong:

  • (b): Elements (child elements) behavior aligns more with PATH when configured that way.
  • (c): Mixing columns into elements vs. attributes requires PATH or EXPLICIT constructs, not RAW by default.


Common Pitfalls:
Assuming RAW provides nested hierarchies; RAW is flat and generic unless combined with additional directives.



Final Answer:
Place the values of the columns as attributes in each XML row element.
