PowerShell SQL Query to Update Table - powershell

Question

I am using PowerShell to run a SQL query. I then want to update another table based on information pulled from the query. I have tested my SQL query and update statements directly in the SQL Server Management Studio so I know that they work. The results of those tests show that there are over 800 records that should be updated. However, when I run the same query and update from within PowerShell, it only updates one record. I have mostly copied this script from another much larger script that was written in a similar format. But it appears that I am missing a ForEach loop (or something similar) but cannot figure out where to place it or how. Here is my script:
# Set the database connection strings
$Conn02 = new-object System.Data.SqlClient.SqlConnection "SERVER_INFORMATION"
$mySQL02 = New-Object System.Data.SqlClient.SqlCommand
$mySQL02.Connection = $Conn02
$Conn03 = new-object System.Data.SqlClient.SqlConnection "SERVER_INFORMATION"
$mySQL03 = New-Object System.Data.SqlClient.SqlCommand
$mySQL03.Connection = $Conn03
#Connect to the database to perform the query
$Conn02.Open()
$mySQL02.CommandText = "SELECT IDNUM, FNAME, LNAME
FROM TABLE1
WHERE STATUS = 'C'"
$SQL02 = $mySQL02.ExecuteReader()
WHILE($SQL02.Read()){
$NEWID = $SQL02['ID_NUM']
$FNAME1 = $SQL02['FNAME']
$LNAME1 = $SQL02['LNAME']
}
#Run the update
$Conn03.Open()
$mySQL03.CommandText =
"INSERT INTO TABLE2 (user_id,firstname,lastname)
VALUES ('$NEWIDme','$FNAME1','$LNAME1')"
Thank you for your time

As #jeroen said, you need to move the Insert statement into the while loop. Here is the code should look like:
#Connect to the database to perform the query
$Conn02.Open()
$mySQL02.CommandText = "SELECT IDNUM, FNAME, LNAME
FROM TABLE1
WHERE STATUS = 'C'"
$SQL02 = $mySQL02.ExecuteReader()
#Save reader into datatable
$Datatable = New-Object System.Data.DataTable
$Datatable.Load($SQL02)
#Close the connection
$Conn02.Close()
#Run the update
$Conn03.Open()
foreach($row in $dt){
$NEWID = $row['ID_NUM']
$FNAME1 = $row['FNAME']
$LNAME1 = $row['LNAME']
$mySQL03.CommandText =
"INSERT INTO TABLE2 (user_id,firstname,lastname)
VALUES ('$NEWIDme','$FNAME1','$LNAME1')"
$mySQL03.ExecuteNonQuery()
}
$Conn03.Close()
To prevent SQL Injection I suggest using Parameters when assigning values
foreach($row in $dt){
$NEWID = $row['ID_NUM']
$FNAME1 = $row['FNAME']
$LNAME1 = $row['LNAME']
$mySQL03.CommandText =
"INSERT INTO TABLE2 (user_id,firstname,lastname)
VALUES (#NEWIDme,#FNAME1,#LNAME1)"
$mySQL03.Parameters.Clear()
$Command.Parameters.AddWithValue('#NEWIDme',$NEWID) | Out-Null
$Command.Parameters.AddWithValue('#FNAME1',$FNAME1) | Out-Null
$Command.Parameters.AddWithValue('#LNAME1',$LNAME1) | Out-Null
$mySQL03.ExecuteNonQuery()
}
