如何设置2选择查询的LIMIT？

Question

can you give a sample to how can i set the limit of my join query.. i used that code for pagination..

select a.last_name, a.first_name, a.middle_name, a.school_year,
a.student_no,a.year_level,DATE_FORMAT(date_register,'%M %d %Y/%r')date_register 
from dbo_student a 
inner join tbl_student_lc b on a.student_no = b.student_no 
order by a.last_name ASC;

Answer 1

Try this :

SELECT a.last_name, a.first_name, a.middle_name, a.school_year,
a.student_no,a.year_level,DATE_FORMAT(date_register,'%M %d %Y/%r')date_register 
FROM dbo_student a 
INNER JOIN tbl_student_lc b ON a.student_no = b.student_no 
ORDER BY a.last_name ASC LIMIT 0, 2;

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants (except when using prepared statements).

With two arguments , the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return. The offset of the initial row is 0 (not 1):

Answer 2

SELECT * FROM `your_table` LIMIT 0, 10 

这将显示数据库的前10个结果。

Answer 3

要添加限制，您可以尝试在查询结束时添加ORDER BY a.last_name ASC LIMIT 0,2 。

Answer 4

Simple add LIMIT 0,2 at the last of your query like

ORDER BY a.last_name ASC LIMIT 0,2   //OR LIMIT 2

This will display first 2 records(rows) from your DB
