我在 xampp 中使用 Laravel 5.4 和 PHP 7.2。我正在尝试截断临时表,然后从 MySQL View 插入新数据。代码执行并完全按照我想要的方式执行,但它说存在错误 -
SQLSTATE[HY000]: General error (SQL: Insert Into prod_joins_temp (date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id) Select date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id From prod_joins)
最初,在将两列插入到我的 View 中后,我遇到了以下错误一般错误:1615 准备好的语句需要重新准备
:time_start
和time_end
列。
我尝试删除这两列以查看这是否是问题所在,但现在我得到的只是可怕的一般错误。
我尝试过这个答案 Laravel: General error: 1615 Prepared statement needs to be re-prepared 。它不起作用,根据评论,它会导致 ak 验证出现问题。
我找到了这个答案PDO error: “ SQLSTATE[HY000]: General error ” When updating database这与我的问题完全相同,但它没有回答我的问题,因为我没有使用 fetchAll() ,也没有使用任何变量的任何重复变量。
我尝试了以下两种方法来实现我的目标。
截断表 prod_joins_temp
ProdJoinsTemp::truncate();
然后从 View prod_joins 填充表 prod_joins_temp
DB::select('Insert Into prod_joins_temp (date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id) Select date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id From prod_joins');
给我完全相同错误的另一种方法如下
删除表 prod_joins_temp(如果存在)
\Schema::dropIfExists('prod_joins_temp');
然后从 View prod_joins 创建表 prod_joins_temp
DB::select('CREATE TABLE prod_joins_temp AS SELECT * FROM prod_joins;');
这是制作 View 的代码
SELECT
`scorecard54`.`production`.`date` AS `date`,
`scorecard54`.`products`.`code` AS `code`,
`scorecard54`.`production`.`sid_production` AS `sid`,
`scorecard54`.`production`.`time_start` AS `time_start`,
`scorecard54`.`production`.`time_end` AS `time_end`,
`scorecard54`.`production`.`made` AS `made`,
`scorecard54`.`qcontrol`.`firsts` AS `firsts`,
`scorecard54`.`qcontrol`.`seconds` AS `seconds`,
`scorecard54`.`production`.`broken_production` AS `p_broken`,
`scorecard54`.`qcontrol`.`broken_qcontrol` AS `q_broken`,
`scorecard54`.`grinding`.`discarded` AS `g_broken`,
`scorecard54`.`products`.`prod_id` AS `prod_id`
FROM
(
(
(
`scorecard54`.`production`
LEFT JOIN `scorecard54`.`products` ON
(
(
`scorecard54`.`production`.`prod_code` = `scorecard54`.`products`.`prod_id`
)
)
)
LEFT JOIN `scorecard54`.`grinding` ON
(
(
`scorecard54`.`production`.`sid_production` = `scorecard54`.`grinding`.`sid_grinding`
)
)
)
LEFT JOIN `scorecard54`.`qcontrol` ON
(
(
`scorecard54`.`grinding`.`tray_id_grinding` = `scorecard54`.`qcontrol`.`tray_id_qcontrol`
)
)
)
WHERE
(
`scorecard54`.`grinding`.`have_qcontrol` = 1
)
这是从 View 中删除并创建表格的函数
public function generateTable(Request $request) {
// Drop temp table
\Schema::dropIfExists('prod_joins_temp');
// re create table with the new data
DB::select('CREATE TABLE prod_joins_temp AS SELECT * FROM prod_joins;');
$request->session()->flash('alert-success', 'Success: Reports table regenerated.');
return Redirect::to('/statistics/');
}
我也尝试过截断然后用这个函数重新填充
public function generateTable(Request $request) {
// Drop temp table
ProdJoinsTemp::truncate();
// re generate table with the new data
DB::select('Insert Into prod_joins_temp (date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id) Select date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id From prod_joins');
$request->session()->flash('alert-success', 'Success: Reports table regenerated.');
return Redirect::to('/statistics/');
}
我在这里做错了什么?是否有某种 View 缓存?
最佳答案
我已经通过这个答案解决了这个问题 SQLSTATE[HY000]: General error: 2053 error occurs at Laravel
之前我使用以下内容更新表格
DB::select('Insert Into prod_joins_temp (date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id) Select date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id From prod_joins');
我更改了要更新的查询的选择部分,一切正常。请看下面
DB::update('Insert Into prod_joins_temp (date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id) Select date,code,sid,time_start,time_end,made,firsts,seconds,p_broken,q_broken,g_broken,prod_id From prod_joins');
我不知道为什么在将字段添加到 View 之前以前的方法有效,但现在它要求我使用更新而不是选择
