Inline user-defined functions are a subset of user-defined functions that return a table]

 

Inline functions cannot return any other data type than table.

Inline User-defined Function Rules

The RETURNS clause contains only the keyword table. You do not have to define the format of a return variable, because it is set by the format of the result set of the SELECT statement in the RETURN clause.

There is no function_body delimited by BEGIN and END.

The RETURN clause contains a single SELECT statement in parentheses. The result set of the SELECT statement forms the table returned by the function. The SELECT statement used in an inline function is subject to the same restrictions as SELECT statements used in views.

The table-valued function accepts only constants or @local_variable arguments

Inline user-defined functions are a subset of user-defined functions that return a table. Inline functions can be used to achieve the functionality of parameterized views.
