fn select_single_rows(
results: Vec<SqlResult>,
) -> Result<Vec<Vec<Value>>, McpRequestError>Expand description
Returns the rows of the single row-returning statement in a response.
A read’s framing statements (BEGIN, SET, COMMIT) report Ok, so only
the user’s statement returns rows. Surfaces the first error, and a second
row-returning statement is an error rather than a dropped result.
