this is my first time posting a question here. I am complete new with Powershell scripting as I am doing new projects. The ERROR I get is Exception calling "ExecuteNonQuery" with "0" argument(s): No Function or Procedure in the Database. I've spent hours trying to figure this out with the help of the internet but can't solve it. The PROCEDURE does exist and I can use it properly with a MySql Query Browser.
Basically I am reading from a database table computer name rows. After reading it will ping each computer and get it's local hard drive information and insert the information in another table to their corresponding fields. Hopefully someone can help me solve this. Keep in mind that I am using MySql and NOT MSSQL. Also, for some reason my call procedure isn't working well when I do $command.CommandText = "nameOfProcedure(@var1,@var2)" Thank you in advance!
