-- ============================================================
-- Class Alias 测试
-- ============================================================

-- class 创建时使用了 nickname='syntax_test'
-- 可以使用别名访问 class

-- 1. 使用全名访问
select s_name from /test/aaa/test_syntax where s_name='syntax_001'
/**
output()
**/
;

-- 2. 确保 class 存在后进行 alias 查询
select s_name from /test/aaa/test_syntax where s_name='syntax_002'
/**
output()
**/
;

-- 3. update alias class
update /test/aaa/test_syntax set s_Value=9999 where s_name='syntax_001'
;

select s_Value from /test/aaa/test_syntax where s_name='syntax_001'
/**
output()
**/
;
