如何使用“BETWEEN”同一列或不同列在一个 sql 语句中使用两次条件

发布于 2024-11-05 17:48:42 字数 250 浏览 4 评论 0原文

这是sql语句只给出一个值

SELECT count(pn1) FROM pledges
WHERE date1
BETWEEN '2011-05-05' AND '2011-06-06'

我想对同一列或同一表中的不同列多次使用“之间”

例如我想在date1中使用它多次或者我想将它用于date1和date2不同范围

注意：我正在使用 java DB Derpy(JDBC-Derby)

原文

this is sql statement give only one value

SELECT count(pn1) FROM pledges
WHERE date1
BETWEEN '2011-05-05' AND '2011-06-06'

i want use "between" more than one time for same column or for different columns in same table

for example i want use it in date1 more than one time or i want use it for date1 and date2 with different range

NOTE:I'm using java DB Derpy(JDBC-Derby)

同一列不止一次：

SELECT count(pn1) 
    FROM pledges
    WHERE date1 BETWEEN '2011-05-05' AND '2011-06-06'
       OR date1 BETWEEN '2011-07-05' AND '2011-08-06'

两个不同的列：

SELECT count(pn1) 
    FROM pledges
    WHERE date1 BETWEEN '2011-05-05' AND '2011-06-06'
      AND date2 BETWEEN '2011-05-05' AND '2011-06-06'

编辑：根据评论，也许您正在寻找类似的东西？

SELECT SUM(CASE WHEN date1 BETWEEN '2011-05-05' AND '2011-06-06' THEN 1 ELSE 0) END AS Count1,
       SUM(CASE WHEN date1 BETWEEN '2011-07-05' AND '2011-08-06' THEN 1 ELSE 0) END AS Count2
    FROM pledges
    WHERE date1 BETWEEN '2011-05-05' AND '2011-06-06'
       OR date1 BETWEEN '2011-07-05' AND '2011-08-06'

More than once for the same column:

SELECT count(pn1) 
    FROM pledges
    WHERE date1 BETWEEN '2011-05-05' AND '2011-06-06'
       OR date1 BETWEEN '2011-07-05' AND '2011-08-06'

Two different columns:

SELECT count(pn1) 
    FROM pledges
    WHERE date1 BETWEEN '2011-05-05' AND '2011-06-06'
      AND date2 BETWEEN '2011-05-05' AND '2011-06-06'

EDIT: Based on comment, perhaps you're looking for something like this instead?

SELECT SUM(CASE WHEN date1 BETWEEN '2011-05-05' AND '2011-06-06' THEN 1 ELSE 0) END AS Count1,
       SUM(CASE WHEN date1 BETWEEN '2011-07-05' AND '2011-08-06' THEN 1 ELSE 0) END AS Count2
    FROM pledges
    WHERE date1 BETWEEN '2011-05-05' AND '2011-06-06'
       OR date1 BETWEEN '2011-07-05' AND '2011-08-06'
