用mysql实现Codeigniter中的“create view”和"Other query“合并问题 、、、 在phpmyadmin中,我运行两个查询都在工作,我得到了我的值,但是当我想在codeigniter中执行这个查询时,我遇到了如何使用相同的function.In执行这两个查询的问题,下面是我的查询。查询: create view V_average_marks AS select student_id,avg...
不同的是query()方法中,普通ezsql类中(ez_sql_mysql.php query方法)采用的是: $this->rows_affected = @mysql_affected_rows($this->dbh); 1. 而集成到CI中ezsql库(libraries/ezsql_codeigniter.php query方法)采用的是: $this->rows_affected = $this->CI->db->affected_rows(); 1. 接着查看system/...
不过,我的UPDATE语句需要改进,而且我不确定语法是否正确。$query3 = "UPDATE `offices` SET `scash`="$total" WHERE `officename`="$office""; offices是表名。scash是要更新的行。$total是从post中提取的变量。$office是从同一数据库中提取的变量。我只想将scash设置为total,其中$office名称是$office。解析错...

你的update查询应在foreach循环开始时间quantity以及medicine两者都是一个数组。应该是这样的：
$sql.="END WHERE id IN ($ids)"; echo$sql; mysql_query($sql); 在这个例子中总共更新了8行数据,但是只执行了一次数据库查询,相比于循环执行8次UPDATE语句,以上例子所节约的时间可以说是微不足道的。但是想想,当你需要更新10,0000或者更多行记录时,你会发现这其中的好处!唯一要注意的问题是SQL语句的长度...
I found the reason is 'ORDER BY .<primary key>' is always appended to the end of the query. Emptying the $primaryKey does not fix the problem. Similiar problem with update(). It works fine with insert(). I'm using the query builder for workaround for now. CodeIgniter 4 version Code...
I was initially thrown by the delete part of things but can see where you're going with this. I work with joined updates and deletes all the time, but hadn't thought of using a nested select as the where clause in CI (was hoping CI could handle it within query builder). It's ...
