MySQL插入中的Powershell数组值输出整个数组

标签： mysql arrays powershell

首先，我是Powershell的新手，因为这是我的第一次尝试。我正在做我可以用其他语言编程，所以我可以破解这个项目。我现在花了几天时间试图解决这个问题，我知道这是愚蠢的。我只是卡住了。

# Insert into master table
$query = "INSERT INTO ``master``(``diff``, ``key``) VALUES ('$diff', '$key')"
Invoke-MySqlQuery -Query $query
$query

这样可以正常显示测试输出：

INSERT INTO `master`(`diff`, `key`) VALUES ('248', 'k000002143200000000000000680006080005500900030082670009461000500000091000000000000')

它也可以很好地输入MySQL数据库。

以下完全相同的格式对我不起作用。就像我在顶部说的那样，我知道这是一些我不知道的愚蠢格式。

# Insert into answers table
$query = "INSERT INTO ``puzzles``(``id``, ``p1``, ``p2``, ``p3``, ``p4``, ``p5``, ``p6``, ``p7``, ``p8``, ``p9``, ``p10``, ``p11``, ``p12``, ``p13``, ``p14``, ``p15``, ``p16``, ``p17``, ``p18``, ``p19``, ``p20``, ``p21``, ``p22``, ``p23``, ``p24``, ``p25``, ``p26``, ``p27``, ``p28``, ``p29``, ``p30``, ``p31``, ``p32``, ``p33``, ``p34``, ``p35``, ``p36``, ``p37``, ``p38``, ``p39``, ``p40``, ``p41``, ``p42``, ``p43``, ``p44``, ``p45``, ``p46``, ``p47``, ``p48``, ``p49``, ``p50``, ``p51``, ``p52``, ``p53``, ``p54``, ``p55``, ``p56``, ``p57``, ``p58``, ``p59``, ``p60``, ``p61``, ``p62``, ``p63``, ``p64``, ``p65``, ``p66``, ``p67``, ``p68``, ``p69``, ``p70``, ``p71``, ``p72``, ``p73``, ``p74``, ``p75``, ``p76``, ``p77``, ``p78``, ``p79``, ``p80``, ``p81``) VALUES ('$id', '$p[0]', '$p[1]', '$p[2]', '$p[3]', '$p[4]', '$p[5]', '$p[6]', '$p[7]', '$p[8]', '$p[9]', '$p[10]', '$p[11]', '$p[12]', '$p[13]', '$p[14]', '$p[15]', '$p[16]', '$p[17]', '$p[18]', '$p[19]', '$p[20]', '$p[21]', '$p[22]', '$p[23]', '$p[24]', '$p[25]', '$p[26]', '$p[27]', '$p[28]', '$p[29]', '$p[30]', '$p[31]', '$p[32]', '$p[33]', '$p[34]', '$p[35]', '$p[36]', '$p[37]', '$p[38]', '$p[39]', '$p[40]', '$p[41]', '$p[42]', '$p[43]', '$p[44]', '$p[45]', '$p[46]', '$p[47]', '$p[48]', '$p[49]', '$p[50]', '$p[51]', '$p[52]', '$p[53]', '$p[54]', '$p[55]', '$p[56]', '$p[57]', '$p[58]', '$p[59]', '$p[60]', '$p[61]', '$p[62]', '$p[63]', '$p[64]', '$p[65]', '$p[66]', '$p[67]', '$p[68]', '$p[69]', '$p[70]', '$p[71]', '$p[72]', '$p[73]', '$p[74]', '$p[75]', '$p[76]', '$p[77]', '$p[78]', '$p[79]', '$p[80]')"
$query
$p[0]
$p[1]
$p[2]
$p[3]
$p[4]
$p[5]
Invoke-MySqlQuery -Query $query

这是我在其中一个跑步中获得的输出：

在$ query变量中，$ p [X]不像下面的$ p [X]那样工作。它正在吐出整个阵列。显然它在将它发送到MySQL时不起作用，我得到了正确的ID，就是这样。

先谢谢大家的帮助，过了一会儿就把头撞在键盘上了！

奖金问题！关于这方面的任何提示都会很棒。任何0都不需要在那里，我实际上希望它们为NULL。任何有关干净方式的提示都会很精彩。完全披露我还没有看过这部分！

我删除了与$ p无关的所有其他代码，以便轻松实现目标。

答案 0 :(得分：1)

您需要使用subexpression operator $()在字符串插值期间评估该索引处的集合。如果没有此运算符，则会打印整个集合的内容以及文字索引语法。

您的第一个示例按预期工作，因为您只是插入简单变量，而不对它们进行任何额外的工作。

以下是命令行中的一个简单示例：

C:\> $arr = 1,2,3,4

字符串之外：

C:\> $arr[0]          
1

在字符串插值期间，没有子表达式运算符：

C:\> "$arr[0]"        
1 2 3 4[0]

在字符串插值期间，使用子表达式运算符：

C:\> "$($arr[0])"     
1

这意味着你的例子会变成这样：

...VALUES ('$id', '$($p[0])', '$($p[1])'...

请注意$id正常工作，因为它是一个简单的变量。您只需要使用子表达式运算符来执行其他工作，例如评估索引，属性等。

如果您想进一步研究，这个概念有时也被称为变量扩展。
