An issue about create a function in Stored Procedures

Hello everyone:

I want to make a function in stored procedures as follows:

SET @update_stmt1320=CONCAT('CREATE FUNCTION ', db,".`getLearningCenterCategoryChildNodes`(rootId INT)
RETURNS varchar(1000)
BEGIN
DECLARE sTemp VARCHAR(1000);
DECLARE sTempChd VARCHAR(1000);

SET sTemp = '$';
SET sTempChd =cast(rootId as CHAR);

WHILE sTempChd is not null DO
SET sTemp = concat(sTemp,',',sTempChd);
SELECT group_concat(cid) INTO sTempChd FROM learning_center_category where FIND_IN_SET(parent_id, sTempChd)>0;
END WHILE;
RETURN sTemp;
END");
PREPARE stmt1320 FROM @update_stmt1320;
EXECUTE stmt1320;
DEALLOCATE PREPARE stmt1320;

It seems mysql prepare statement not support create function in stored procedures. But I really need to create function in stored procedures with user input database name.

So what can I do? Who can help me out?
Thanks in advance!
