PHP的mysql_query - 獲取本週的行與當前日期

Question

我有一個MySQL表如下：

week start_date end date 
1 2011-04-25 2011-05-01 
2 2011-05-02 2011-05-08 
3 2011-05-09 2011-05-15 

我想運行一個查詢來獲取週數在當前日期爲起始日期和之間指定周的end_date。

Answer 1

SELECT week 
FROM table_name 
WHERE CURRENT_DATE() BETWEEN start_date AND end_date 

CURRENT_DATE（）爲CURDATE（）同義詞。

Answer 2

相當簡單：

SELECT week FROM my_table WHERE CURRENT_DATE > start_date AND CURRENT_DATE <= end_date 

Answer 3

SELECT week FROM TABLE_NAME WHERE CURDATE() BETWEEN start_date AND end_date;
