如何筛选INNER JOIN SQL命令结果

Question

我有一个记录表单提交的表。对于具有以下形式的每个提交有下列变量：

userid 
record 
accountName 
accountNumber 

当用户提交的形式，该表被填充有每行项record值。换句话说，这些值通常都由record值链接。我正在尝试用户INNER JOIN将结果过滤到将userid，accountName和accountNumber显示为列的表上。我非常接近这个命令：

SELECT t1.value AS number, t2.value AS name, t3.value AS userid 
FROM mytable AS t1 
INNER JOIN mytable AS t3 
INNER JOIN mytable AS t2 ON t1.record = t2.record 
WHERE t1.name = 'addAccountNumber' 
AND t2.name = 'addAccountName' 
AND t3.name = 'userid' 

唯一的问题是结果不限于每个条目。看起来多个实例正在桌面上显示。

我相信需要对声明的WHERE部分进行一些编辑。在我看来，结果并没有考虑名称值和过滤结果。有关如何解决这个问题的任何建议？

更新：

我要补充一点，我得到了适当的过滤结果时，我只包括在通话两行，在这里看到：

SELECT t1.value AS accountNumber, t2.value AS accountName 
FROM mytable AS t1 
INNER JOIN mytable AS t2 
ON t1.record=t2.record WHERE t1.name='addAccountNumber' AND t2.name='addAccountName' 

思想，可以帮助显示什么我来自。所以，总的来说，这与添加userid变量给我带来的麻烦有关

Answer 1

我很难理解你需要什么，但也许就是这样。

SELECT t1.value AS number, t2.value AS name, t3.value AS userid 

FROM mytable AS t1 

INNER JOIN mytable AS t3 ON t1.record = t3.record 

INNER JOIN mytable AS t2 ON t1.record = t2.record 

WHERE t1.name = 'addAccountNumber' 

AND t2.name = 'addAccountName' 

AND t3.name = 'userid'
