SQL查询不删除数据

Question

SQL is not deleting all the data in the query

SQL TABLE

BD int,
un  varchar(255),
branch varchar(255),
dates varchar(255),
morning_in varchar(5) default '{$time[0]->end}',
morning_out varchar(5) default '{$time[0]->end}',
afternoon_in varchar(5) default '{$time[1]->end}',
afternoon_out varchar(5) default '{$time[1]->end}'

I need it to delete between 05:00 to 07:10

$mssqldb->get_results("DELETE from tempUSERlog
        where morning_in BETWEEN '05:00' AND '07:10' AND
         afternoon_in BETWEEN '15:30' AND '16:10'");

I need it to delete between 07:00 to 12:10

$mssqldb->get_results("DELETE from tempUSERlog
where morning_in = '07:00' AND 
morning_out ='12:00' AND afternoon_in='16:00'
and afternoon_out='18:00'");

Im using this piece of class link

PDO have issues on my Windows server.

What am I doing wrong?

Answer 1

我认为您应该使用“或”运算符而不是“与”运算符。

Answer 2

I think you mean this:

DELETE from tempUSERlog
WHERE morning_in >= '07:00'
AND morning_out <= '12:00'
AND afternoon_in >= '16:00'
AND afternoon_out <= '18:00'

Probably you need to include your dates in your WHERE clause

Answer 3

You should use exec function in deleting data like the example in the link below. http://www.w3schools.com/php/php_mysql_delete.asp

The function get_results should be used to get data not to delete data
