Answer 2

您必须指定database name.

检查这个，

SHOW TABLES FROM `database-name` LIKE '%a%' 

请参阅此处的mysql 文档

要获取表名，

 $tables=$this->db->query("SELECT t.TABLE_NAME AS myTables FROM INFORMATION_SCHEMA.TABLES AS t WHERE t.TABLE_SCHEMA = 'database name' AND t.TABLE_NAME LIKE '%a%' ")->result_array();    
 foreach($tables as $key => $val) {
      echo $val['myTables']."<br>";// myTables is the alias used in query.
 }
