这个是我创建的函数, 我吧返回值varchar改成了2W还是报字符串截断的错误
CREATE OR REPLACE FUNCTION “SYSDBA”.“QUERYCHILDRENAREAINFO”(“areaId” IN VARCHAR(64))
RETURN VARCHAR(20000)

AS
DECLARE
sTempChd VARCHAR(10000);
sTemp VARCHAR(20000);
BEGIN
sTemp = ‘$’;
sTempChd = CAST(areaId AS VARCHAR(10000));
WHILE sTempChd IS NOT NULL LOOP

	sTemp = CONCAT(sTemp, ',', sTempChd);
	print length(sTemp);
	SELECT WM_CONCAT(oid) INTO sTempChd
	FROM org_organization
	WHERE sys_isdeleted = '0'AND FIND_IN_SET(parent_Id, sTempChd) >0;
END LOOP;
RETURN sTemp;

END;
