I have a sql table where the app is writing. A unix timestamp value to the field. I would like to iterate thru the table and pull from a specific datetime but not sure how to code that in PS that also would export to csv file.
I just pulled the latest record from table --
t_stamp=1711065382576
My Current datetime 3/21/2024 07:56PM
Data Record
7384, , 57.3080520629883 ,, , 192, 1711065382576
```
CREATE TABLE [dbo].[plc_data_4_2024_03](
[tagid] [int] NOT NULL,
[intvalue] [bigint] NULL,
[floatvalue] [float] NULL,
[stringvalue] [nvarchar](255) NULL,
[datevalue] [datetime] NULL,
[dataintegrity] [int] NULL,
[t_stamp] [bigint] NOT NULL,
PRIMARY KEY CLUSTERED 
(
[tagid] ASC,
[t_stamp] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
```
Thanks.

you can start by reading the manual - https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/get-date?view=powershell-7.4

and as alternative, you pass your desired date in date format to your sql, and within the sql itself you convert to your unixtimestamp - which you have already been told many times how to do.

Why on Earth would you use PoSh to do this? You have the data in a table already.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
