Problem: I want to select row in MySql based on user supplied month value, checking should go through all the records and check each date coloum by month. I have a table lets say 

id int(4), date date

Now I want to retrieve this data using select statement, in the select statement i want to check the date by month not by the whole date because user has suppllied value in month ! whole date.

For example I want to make this kind of query: 

select * 
  from `Table` 
 where id=123 
   And date = "value in month"

Many thanks.

使用MONTH零件。

SELECT ...
WHERE MONTH(date) = 5

尝试

SELECT * 
  FROM Table1 
 WHERE id = 123 
   AND MONTH(date) = 3

如果你也关心一年

SELECT * 
  FROM Table1 
 WHERE id = 123 
   AND MONTH(date) = 3 -- March
   AND YEAR(date)  = 2013

SQLFiddle（对于两个查询）

请注意，date即使存在列，也不会在列上使用任何索引。
