我在打开我的旧网站时遇到了一些问题。我的数据表显示：

DataTables warning: JSON data from server could not be parsed. This is caused by a JSON formatting error.

之后，我试图调试我的脚本，发现错误在mysql：

Error occuered during query execution: 
(<small>SELECT SQL_CALC_FOUND_ROWS ID,name,remark,avrusepmonth 
        , CONCAT('&lt;input type=''checkbox''id=''cb' , ID ,''' name=''check[]''                
        value=''',ID,''' &gt;','&lt;label class=''lbcb'' for=''cb', 
        ID,'''&gt;&lt;=update=&lt;/label&gt;') as checkb 
        ,monthavrage(ID,12) as latestavr , moq, leadtime 
        FROM test_media  WHERE nowuse=1 and monthavrage(ID,12)  &gt; 0  ORDER BY  name
        desc, ID
        LIMIT 0, 10</small>):
 execute command denied to user 'jeinqa'@'localhost' for routine 'TestMediaControl.monthavrage'

然后我试着在谷歌上搜索execute command denied to user 'jeinqa'@'localhost' for routine 'TestMediaControl.monthavrage'，一些网站说我必须做一些GRANT：

GRANT EXECUTE ON PROCEDURE TestMediaControl.monthavrage TO 'jeinqa'@'localhost'

但我得到了

#1370 - execute command denied to user 'jeinqa'@'localhost' for routine 'TestMediaControl.monthavrage'

你能告诉我怎么解决这个问题吗？
