Returning multiple result sets from procedures

Before Interactive SQL can return multiple result sets, you need to enable this option on the Results tab of the Options window. By default, this option is disabled. If you change the setting, it takes effect in newly created connections (such as new windows).

To enable multiple result set functionality (Sybase Central)
  1. Connect to the database as a user with DBA authority.

  2. In the left pane, select the database and choose File » Open Interactive SQL.

  3. In Interactive SQL, choose Tools » Options.

  4. Click SQL Anywhere.

  5. On the Results tab, select Show All Result Sets.

  6. Click OK.

After you enable this option, a procedure can return more than one result set to the calling environment. If a RESULT clause is employed, the result sets must be compatible: they must have the same number of items in the SELECT lists, and the data types must all be of types that can be automatically converted to the data types listed in the RESULT list.


The following procedure lists the names of all employees, customers, and contacts listed in the database:

RESULT ( Surname CHAR(36), GivenName CHAR(36) )
   SELECT Surname, GivenName
   FROM Employees;
   SELECT Surname, GivenName
   FROM Customers;
   SELECT Surname, GivenName
   FROM Contacts;

To test this procedure and view multiple result sets in Interactive SQL, enter the following statement in the SQL Statements pane:

CALL ListPeople ();
