How do I pass parameters properly? - powershell

Question

Please see my Function-to-be below:
Function Query {
param (
[string]$query
[string]$server
[string]$dbase
[string]$user
[string]$pass
)
if ($user) {
$connstr = "Server={0};Database={1};User ID={2};Password={3};Trusted_Connection=False;Connect Timeout=15" -f $server, $dbase, $user, $pass
}
else {
$connstr = "Server={0};Database={1};Integrated Security=True;Connect Timeout=15" -f $server, $dbase
}
$conn.ConnectionString = $connstr
switch ($query.Split()[0]) {
"SELECT" {
$cmd = New-Object System.Data.SqlClient.SqlCommand($query,$conn)
$adapter = New-Object System.Data.SqlClient.SqlDataAdapter($cmd)
$dataset = New-Object System.Data.DataSet
$adapter.Fill($dataset) | Out-Null
return $dataset
}
"UPDATE" {
$cmd = New-Object System.Data.SqlClient.SqlCommand($query,$conn)
return $cmd.ExecuteNonQuery()
}
"INSERT" {
$cmd = New-Object System.Data.SqlClient.SqlCommand($query,$conn)
return $cmd.ExecuteNonQuery()
}
}
}
Query -query "SELECT TOP 10 myField FROM myTable" -server "SQLEXPRESS" -dbase "TEST"
This doesn't work, Powershell ISE gives me red in the param section but I don't understand why. Because of the many different ways people seem to construct Powershell functions (I'm a beginner :)) I am somewhat confused.
How do I make this function work?

Answer 1

Put commas , between the parameters:
Function SomeName {
Param ($param1,$param2,$param3)
}
etc. You can use whitespace or line break after the comma for readability, which is what most people do:
Function SomeName {
param (
$param1,
$param2
)
}
