统计数量标签是不是不支持like查询

{count action=sql sql='SELECT * FROM dr_1_share_category WHERE  `dr_1_share_category`.`pid` IN (532)  '  } {$debug_count}

这种的where条件就可以

{count action=sql sql='SELECT * FROM dr_1_share_category WHERE `dr_1_share_category`.`name` LIKE '%关键词%'  '  } {$debug_count}

或者

{count action=sql sql='SELECT * FROM dr_1_share_category WHERE name LIKE '%关键词%'  '  } {$debug_count}

这样的where条件就报错了 ,好像 '%关键词%'   没传递过去一样

 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

#SQL：SELECT count(*) as ct FROM dr_1_share_category where `dr_1_share_category`.`name` LIKE

是不是要添加转意符，怎么弄？指点下
