在导入时将CSV导入到本地主机错误

Question

我遇到了一些问题，一直出现错误消息，我找不到原因。

我正在尝试构建一个在我的PC上利用WAMP的数据库功能来存储和操作数据而不是使用MS Access的进程。

下面的脚本包含我一直在处理的当前powershell脚本，它创建一个新的数据库和表来包含我的CSV数据，但是当我试图将CSV数据插入新创建的表格时，有两个重复的错误。

The property 'CommandText' cannot be found on this object. Verify that the property exists and can be set.

而且

Cannot convert value ",'" to type "System.Int32". Error: "Input string was not in a correct format."

我只是茫然地如何纠正这一点，为什么它抛出的错误，这是有目共睹的人吗？

$dbnameone = "brokerreconciliation"

$mysqlConn = New-Object -TypeName MySql.Data.MySqlClient.MySqlConnection 
$mysqlConn.ConnectionString = "SERVER=localhost;DATABASE=brokerreconciliation;UID=root;PWD=''" 
$mysqlConn.Open() 

$ccmd = New-Object MySql.Data.MySqlClient.MySqlCommand 
$ccmd.Connection = $mysqlConn 
$ccmd.CommandText = "DROP DATABASE IF EXISTS " + $dbnameone 
$ccmd.ExecuteNonQuery()

    $cmd.CommandText = 
     "INSERT INTO customers (id,cl2accountcode,acbalance,parname1) VALUES (" 
     +$i.id+",'"+$i.cl2accountcode+"','"+$i.acbalance+"','"+$i.parname+"');" 
    $cmd.ExecuteNonQuery() 
} 

Import-Csv $CL2Location ##Added to ensure that the data file was being reached it is 

$mysqlConn.Close() 

示例CSV数据的链接是here。

试图解决此问题我试图直接从通过初始SQL查询创建的数据表中写入数据，以减少我需要的步骤数量。下面的代码是更新，即使直接使用结果集，当我尝试将数据上载到本地主机时，我仍然遇到相同的错误。

我也编辑了CREATE TABLE元素来完全匹配基础数据库的模式，以确保没有任何问题导致此问题。

对于我如何无法将信息从CSV或脚本传递到本地主机上新创建的表，我仍然感到不知所措。

Answer 1

你不能完成的字符串是这样的：

$ccmd.CommandText = 
    "INSERT INTO customers (cl2accountcode,cbalance,parname1) VALUES (" 
    +$i.cl2accountcode+"';'"+$i.cbalance+"';'"+$i.parname+"');" 

的PowerShell将解释

$ccmd.CommandText = 
    "INSERT INTO customers (cl2accountcode,cbalance,parname1) VALUES (" 

和

+$i.cl2accountcode+"';'"+$i.cbalance+"';'"+$i.parname+"');" 

单独的语句，因为前两行是一个完整的声明d自己。因为+$i.cl2accountcode（即$null + [int]）变成了一个整数，并且[int] + [string]仅在字符串可以转换为整数（对于字符串​​3210不是这种情况）时才有效，所以第三行会抛出错误。

为了使字符串连接工作跨越你需要或者逃避线的线条打破

$ccmd.CommandText = 
    "INSERT INTO customers (cl2accountcode,cbalance,parname1) VALUES (" ` 
    +$i.cl2accountcode+"';'"+$i.cbalance+"';'"+$i.parname+"');" 

或将连接符在该行的末尾（这样的PowerShell知道有更多的惊喜）

$ccmd.CommandText = 
    "INSERT INTO customers (cl2accountcode,cbalance,parname1) VALUES (" + 
    $i.cl2accountcode+"';'"+$i.cbalance+"';'"+$i.parname+"');"
