Returning result sets from Transact-SQL procedures

SQL Anywhere uses a RESULT clause to specify returned result sets. In Transact-SQL procedures, the column names or alias names of the first query are returned to the calling environment.

Example of Transact-SQL procedure

The following Transact-SQL procedure illustrates how Transact-SQL stored procedures returns result sets:

CREATE PROCEDURE ShowDepartment (@deptname varchar(30))
AS
   SELECT Employees.Surname, Employees.GivenName
   FROM Departments, Employees
   WHERE Departments.DepartmentName = @deptname
   AND Departments.DepartmentID = Employees.DepartmentID;

Example of Watcom-SQL procedure

The following is the corresponding SQL Anywhere procedure:

CREATE PROCEDURE ShowDepartment(in deptname varchar(30))
RESULT ( LastName char(20), FirstName char(20))
BEGIN
   SELECT Employees.Surname, Employees.GivenName
   FROM Departments, Employees
   WHERE Departments.DepartmentName = deptname
   AND Departments.DepartmentID = Employees.DepartmentID
END;
