试试这个

select tblPersonalInfo.companyname, tblJobBudget.title,tblJobBudget.lastmodifiedby,
tblJobAdv.advtitle, tblJobAdv.userId,       
tblApplication.advid, tblApplication.position
from tblJobAdv 
inner join tblApplication
ON tblJobAdv.advid = tblApplication.advid
inner join tblPersonalInfo
On tblJobBudget.lastmodifiedby = tblPersonalInfo.userid

给出错误

Msg 4104, Level 16, State 1, Line 8
The multi-part identifier "tblJobBudget.lastmodifiedby" could not be bound.
Msg 4104, Level 16, State 1, Line 2
The multi-part identifier "tblJobBudget.title" could not be bound.
Msg 4104, Level 16, State 1, Line 2

无法绑定多部分标识符“tblJobBudget.lastmodifiedby”。

嘿,我正在使用oracle sql来创建数据库.

我现在正在处理查询,我想出了两个单独的quires,我想合并以获得结果.

我创建的第一个查询是查找演出所产生的总金额:

    SELECT SUM(bookings * CategoryPrice )AS Total_Money_Made
    FROM ( SELECT CategoryPrice , count(*) AS bookings
       FROM Booking b
       JOIN performance per
         ON b.performanceid =  per.performanceid
       JOIN Production p
         ON per.productionid = p.productionid          
      WHERE per.performanceid IN (1, 2, 3, 4)
      GROUP BY CategoryPrice)

这给了我一个结果:

TOTAL_MONEY_MADE

       337.5 

然后我有另一个查询,计算出总的特许金:

              SELECT SUM(ConsessionAmount * 2) AS Total_Consession_Money
      FROM( SELECT COUNT (*) AS ConsessionAmount
FROM Booking 
WHERE 
Consession = 'Yes' AND PerformanceID = '1' OR 
Consession = 'Yes' AND PerformanceID = '2' OR …

使用 SO 上其他地方的示例来更好地捕获“隐藏”错误。虽然下面的代码将捕获并返回错误，但是否可以改进它以报告发生错误的查询？

使用下面的代码，输出是：

Columns: 18
Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FRO inventory' at line 1

正在测试的代码：

$query = "SELECT * FROM orders WHERE location = 'IN' ORDER BY orderNum DESC LIMIT 20;";
$query .= "SELECT * FRO inventory";             //  With error
$ord = array();
$invent = array();

if(mysqli_multi_query($link, $query)) {
    do {
        // fetch results
        if($result = mysqli_store_result($link)) …
