我在php文件中有一个postgresql查询,它返回了一百多条记录。我想在使用相同查询时每页只查看10条记录。我使用的查询如下:
SELECT
to_char(a.CALLDATE,'yyyymm') AS month,
min(a.calldate) AS start_time,
max(a.calldate) AS end_time,
ceil(sum(a.CALLDURATION::integer) / 60) AS minutes,
count(DISTINCT a.IDENTIFIANT) AS distinct_callers,
a.zoneiddest AS country_code,
b.country
FROM cdr_data a,
COUNTRY_CODES b
WHERE
a.CALLSUBCLASS = '002'
AND
a.CALLCLASS = '008'
AND
a.zoneiddest::integer > 0
AND
substr(a.CALLEDNUMBER, 1, 2) NOT IN ('77', '78', '75', '70', '71', '41', '31', '39', '76','79')
AND
NOT substr(a.zoneiddest , 1 ,3) IN ('254','255','256','211','257','250','256')
AND
trim(a.zoneiddest) = trim(b.country_code)
GROUP BY
to_char(a.CALLDATE,'yyyymm'),
a.zoneiddest,
b.country
ORDER BY 1
我尝试过使用JavaScript,但它不起作用。有没有办法可以编辑这个查询或者在php中做些什么来实现我想要的东西?
如果有人在那里提供帮助,我将不胜感激,因为如果它与php和mysql的分页似乎有很多解决方案,但与php和postgresql没那么多。
答案 0 :(得分:1)
简单的解决方案是追加:
OFFSET 20
LIMIT 10
