powershell-如何获取日期

Question

I have the following

foreach($res in $result1)
    {
        $ed = $res.EVENT_DATE
    }

$ed is

29 September 2015 00:00:00

(It comes out of a MySQL Database as '2015-09-29' - but I'm assuming powershell is being 'clever' and converting it).

However, I need it to display as '

2015-09-27

I tried:

$ed = $res.EVENT_DATE
$ed = get-date -date $ed

With the intention of then formatting it accordingly, But this gives me

Get-Date : Cannot bind parameter 'Date' to the target. 
Exception setting "Date": "Object reference not set to an instance of an object."

What is the correct way of formatting this to display as required?

Answer 1

How Powershell displays it depends on your locale info. For example:

D:\> get-date "29 September 2015 00:00:00"

Tuesday, September 29, 2015 12:00:00 AM

D:\> get-date "29 September 2015 00:00:00" -Format yyyy-MM-dd
2015-09-29

so you might try this:

foreach($res in $result1)
    {
        $ed = get-date $res.EVENT_DATE -format yyyy-MM-dd
    }
