Can't call PowerShell script for database access (MYSQL) - mysql

Question

Using this database connection script I have found here. I have modified it and did the proper setting to let the script run but don't understand the error I am getting.
The script code is here:
Param(
[Parameter(
Mandatory = $true,
ParameterSetName = '',
ValueFromPipeline = $true)]
[string]$Query
)
$MySQLAdminUserName = 'myName'
$MySQLAdminPassword = 'myPass'
$MySQLDatabase = 'myDatabase'
$MySQLHost = 'HostingServerForMyDatabase'
$ConnectionString = server= + $MySQLHost + ;port=3306;uid= + $MySQLAdminUserName + ;pwd= + $MySQLAdminPassword + ;database=+$MySQLDatabase+
Try {
[void][System.Reflection.Assembly]LoadWithPartialName(MySql.Data)
$Connection = New-Object MySql.Data.MySqlClient.MySqlConnection
$Connection.ConnectionString = $ConnectionString
$Connection.Open()
$Command = New-Object MySql.Data.MySqlClient.MySqlCommand($Query, $Connection)
$DataAdapter = New-Object MySql.Data.MySqlClient.MySqlDataAdapter($Command)
$DataSet = New-Object System.Data.DataSet
$RecordCount = $dataAdapter.Fill($dataSet, data)
$DataSet.Tables[0]
}
Catch {
Write-Host ERROR Unable to run query $query `n$Error[0]
}
Finally {
$Connection.Close()
}
And so, this is the error I recieve with the following command -
COMMAND: .\MySQL.ps1 -Query "select GUID FROM MYTABLE"
ERROR:Parameter declerations are a comma-serperated list of variable names with optional initializer expressions. At (my script file path)\MySQL.ps1:5 char:30 + ValueFromPipeline = $true)] <<<<

Answer 1

Apparently the error is not from running the script as in shown in the question nor in the link, but some unknown other script.
The error message shows you are missing the closing parentheses.
Parameter declerations are a comma-serperated list of variable names
with optional initializer expressions. At (my script file
path)\MySQL.ps1:5 char:30 + ValueFromPipeline = $true>] <<<<
The code you posted here and in the link does have it correct.
Param(
[Parameter(
Mandatory = $true,
ParameterSetName = '',
ValueFromPipeline = $true)]
[string]$Query
)
Notice $true)]
Correct MySQL.ps1 so it is exactly the same as in your link.
