使用一个mysql语句作为另一个mysql语句的变量
我有2个mysql语句,一个从工作人员的4个链接表中获取所有信息.我试图获取另一个表中的每个工作人员的标题,但我不能添加到1个语句,因为它与所选的主表无关.我在mysql语句中尝试了大约20种变体但没有成功.我确实得到了它来拉取标题并通过第二个语句中的变量输出它,但是它给每个人提供了相同的标题,当它再次循环时似乎没有更新变量.
第一个mysql语句读取(简化版本很长)
SELECT staff_tbl.titleID FROM staff_tbl
第二个mysql语句读取
SELECT titles_tbl.titleID, titles_tbl.titleName FROM titles_tbl WHERE titles_tbl.titleID = '" . $getTitle . "'"
变量设置为($ row_rsOfficeLocation是第一个mysql语句的结果)
$getTitle = $row_rsOfficeLocation['titleID'];
每次在第一个语句中更新时,是否有人知道如何在第二个语句中请求时更新$ getTitle变量？

Sample Output would be like so:
It is working except for the fact that all the titles it outputs are the same for every staff member. The code I am using is the one I posted earlier for the second select statement. I don't know if it would be easier if I could just figure out how to join the titles_tbl to the main sql statement. I have tried several variations from a Union to just the second select within the first one and none of them seem to work or they throw an error.
This is the first sql statement I have been using including all aliases for my joins

Sorry for the long section of code but it would take me an hour to indent it all.
EDIT: Ok so I reworked my mysql statement and got it to pull all the information from the database now. but I have a minor issue with it. On every 3rd iteration of the loop I have it switches the place of my contact 1 and partner in the lists. It only seems to be switching two of them out of order. So if I have 3 contacts it switches the contact1 and contact2 and on the ones where I only have 2 contacts it is switching the order of them.
Here is my new mysql statement I'm using.
SELECT staff_tbl.staffID, staff_tbl.firstName, staff_tbl.middleInitial, staff_tbl.lastName,
staff_tbl.suffix, staff_tbl.accredations, staff_tbl.email, staff_tbl.phone,
staff_tbl.mobilePhone, staff_tbl.officePhone, staff_tbl.faxNumber, staff_tbl.titleID,
staff_tbl.locationID, titles_tbl.titleID, titles_tbl.titleName,
officelocations_tbl.locationID, officelocations_tbl.officeName, officelocations_tbl.address1,
officelocations_tbl.address2, officelocations_tbl.cityID, officelocations_tbl.stateID,
officelocations_tbl.zipCode, officelocations_tbl.officePhone, officelocations_tbl.contact1,
officelocations_tbl.contact2, officelocations_tbl.partner, state_tbl.stateID,
state_tbl.state_abreviation, state_tbl.state_name, city_tbl.cityID, city_tbl.cityName,
officelocations_tbl.contact1 AS c1Contact, officelocations_tbl.contact2 AS c2Contact,
officelocations_tbl.partner AS c3Contact FROM staff_tbl INNER JOIN titles_tbl ON
titles_tbl.titleID = staff_tbl.titleID INNER JOIN officelocations_tbl ON officelocations_tbl.contact1 = staff_tbl.staffID OR officelocations_tbl.contact2 = staff_tbl.staffID
OR officelocations_tbl.partner = staff_tbl.staffID
OR staff_tbl.locationID = officelocations_tbl.locationID
INNER JOIN state_tbl ON state_tbl.stateID = officelocations_tbl.stateID
INNER JOIN city_tbl ON city_tbl.cityID = officelocations_tbl.cityID
For my display I have an if statement to check whether there is a contact1, contact2 and partner. If the contact 2 is empty it will only display contact 1 and partner, while if contact 2 is present it will show all 3 contacts, and an else statement that will show only the partner if there is no contact1 or contact2. The php looping through this works perfectly so there is no error in that. It is the reference to and/or the sql statement that isn't quite right yet that is causing my error. For each loop through I allow the statement to run and when it hits the second (if there is one) contact to fetch the row again. I set a variable equal to the staff_id so that I can have it pull the correct people associated with each location. Before I have it fetch the row I set the staff id to the particular contact example:
$staff_ID == $row_rsOfficeLocation['c3Contact'];
It reads the assignment correct but for some reason it seems to be hitting the fetch assoc call before it reads the assignment to the staff id. Effectively setting the staff id to the second name in the list rather than the first.
Any ideas?

这是一个基本的INNER JOIN:
SELECT
titles_tbl.titleID,
titles_tbl.titleName
FROM
titles_tbl
JOIN staff_tbl ON titles_tbl.titleID = staff_tbl.titleID
WHERE
staff_tbl.titleID = 'some value from your long query'
它也可以使用WHERE子句中的子查询来完成:
SELECT
titles_tbl.titleID,
titles_tbl.titleName
FROM
titles_tbl
WHERE
titleID = (SELECT titleID FROM staff_tbl WHERE <whatever from your long query>)
或者,如果第一个查询旨在返回多行而不是一行,则需要使用IN()子查询
/* Replace the WHERE clause above with */
WHERE
titleID IN(SELECT titleID FROM staff_tbl WHERE <whatever from your long query>)
