SA0245 : Do not use ORDER BY to order the result set in view or inline table-valued function
The topic describes the SA0245 analysis rule.
Do not use ORDER BY to order the result set in view or inline table-valued function
The rule checks T-SQL code for usages of ORDER BY clause in view-s and single statement inline table valued functions.
If there are TOP or FOR XML clauses also specified, the ORDER BY clause is valid and a rule violation will not be reported.
When ORDER BY is used in the definition of a view, inline function, derived table, or subquery, the clause is used only to determine the rows returned by the TOP clause. The ORDER BY clause does not guarantee ordered results when these constructs are queried, unless ORDER BY is also specified in the query itself.
Remove the redundant ORDER BY clause.
The rule has a Batch scope and is applied only on the SQL script.
Rule has no parameters.
The rule does not need Analysis Context or SQL Connection.
