Postgresql - 创建函数 - RAISE INFO不打印预期值

Question

在函数中，在以下行中

RAISE INFO 'MY TEST - Run - 25 - Now periodID is %', periodID;  

我期望变量periodID保存由查询返回的，但它正在显示，但是当我单独执行时，以下查询返回一个整数值，请帮助解决此问题

select distinct periodid into periodID 
                  from ccc_financialperiod fp 
                  where fp.periodtype = 'Year' 
                  and fp.periodfiscalyear = vsYear 
                  and fp.organizationid = oaPermID  
                  and fp.periodduration IN ('12M','P12M', '52W', 'P52W','53W','P53W','365D', 'P365D', 'P364D', 'P371D');
