Import CSV to localhost error on import - mysql

Question

I am having some issues with an error message that keeps coming up and I cannot locate why.
I am trying to build a process that utilises the database functionalities of WAMP on my PC to store and manipulate data rather than use MS Access.
The script below contains the current powershell script that I have been working on which is creating a new database and table to contain my CSV data however when I am trying to insert the CSV data into the newly created table it is presenting me with two repetitive errors.
The property 'CommandText' cannot be found on this object. Verify that the property exists and can be set.
And
Cannot convert value ",'" to type "System.Int32". Error: "Input string was not in a correct format."
I am simply at a loss to how to correct this and why it is throwing errors, is this obvious to anyone?

$cmd.ExecuteNonQuery()
}
Import-Csv $CL2Location ##Added to ensure that the data file was being reached it is
$mysqlConn.Close()
Link to example CSV data is here.
Trying to resolve this problem I have tried to write the data directly from the data table created via the initial sql query to reduce the amount of steps that I would require. The code below is the update, even utilising the result set directly I am still hitting the same errors when I try to upload the data to local host.
I have also edited the CREATE TABLE element to match the schema of the base database exactly to ensure there was nothing with this that was causing the issue.
I am still at a loss as to how I cannot pass the information from either CSV or script to a newly created table on localhost.

You can't wrap strings like this:
$ccmd.CommandText =
"INSERT INTO customers (cl2accountcode,cbalance,parname1) VALUES ("
+$i.cl2accountcode+"';'"+$i.cbalance+"';'"+$i.parname+"');"
PowerShell will interpret
$ccmd.CommandText =
"INSERT INTO customers (cl2accountcode,cbalance,parname1) VALUES ("
and
+$i.cl2accountcode+"';'"+$i.cbalance+"';'"+$i.parname+"');"
as separate statements, because the first two lines are a complete statement in and by themselves. The third line then throws an error, because +$i.cl2accountcode (i.e. $null + [int]) becomes an integer, and [int] + [string] is only valid if the string can be cast to an integer (which is not the case for the string ';').
To make string concatenation work across lines you need to either escape the line break
$ccmd.CommandText =
"INSERT INTO customers (cl2accountcode,cbalance,parname1) VALUES (" `
+$i.cl2accountcode+"';'"+$i.cbalance+"';'"+$i.parname+"');"
or put the concatenation operator at the end of the line (so PowerShell knows there is more to come)
$ccmd.CommandText =
"INSERT INTO customers (cl2accountcode,cbalance,parname1) VALUES (" +
$i.cl2accountcode+"';'"+$i.cbalance+"';'"+$i.parname+"');"
