我现在不知所措，因为即使是最简单的声明，

BEGIN 
        DECLARE rs1 CURSOR WITH RETURN FOR  
            select * from table1;
END

WITH RETURN正在生成一个

SQL Error [42613]: [SQL0628] Clauses not valid in same definition.

文档https://www.ibm.com/docs/en/i/7.3?topic=codes-listing-sql-messages指出：

Clauses specified to define the attributes of a column, a sourced function, a procedure, a trigger, or an index are not valid. One of the following has occurred:

WITH RETURN is specified for a cursor in a compound (dynamic) statement.

如果不将此Select语句视为动态语句，该如何为游标调用它？
