MYSQL查询具有不同字段的两个表

Question

Here is my search query, which is putting out an argument error.
What do I need to do to correct it. Basically I need to put both of these tables together and pull out the next 5 events within the two tables by the start date. You will also notice that the last field in each table is different from one another.

$CEsql = mysql_query("
  SELECT id, title, start, end, allDay
  FROM calendar 
  WHERE mem_id='$logOptions_id' 
    AND start >= DATE_SUB( CURDATE( ) ,INTERVAL 0 MONTH ) 

  UNION ALL 

  SELECT id, title, start, end, allDay
  FROM team_calendar 
  WHERE team_id IN ($team_array) 
    AND start >= DATE_SUB( CURDATE( ) ,INTERVAL 0 MONTH ) 
  ORDER BY start ASC LIMIT 5");

I am using MYSQL 5.0 and PHP.

Update

mysql_error displays:

1267: Illegal mix of collations for operation 'UNION'

Answer 1

Run SHOW CREATE TABLE statements for both tables. Find differences between two tables, check charsets and collations as Leap Bun suggested. Then you may change field charset/collation, or just try to use COLLATE clause in your SELECT query. Something like this -

SELECT id, title, start, end, allDay
  FROM calendar 
  WHERE mem_id='$logOptions_id' 
    AND start >= DATE_SUB( CURDATE( ) ,INTERVAL 0 MONTH ) 

  UNION ALL 

  SELECT id, 
    title COLLATE collation_name AS title, -- write your collation here
    start, end, allDay
  FROM team_calendar 
  WHERE team_id IN (1,2) 
    AND start >= DATE_SUB( CURDATE( ) ,INTERVAL 0 MONTH ) 
  ORDER BY start ASC LIMIT 5
