SELECT Statement Doesn't Get Records With Dates

I have a table which is populated with production data from our shop floor.  Part of what I'm trying to do is get all records from yesterday so we can output what has gone on the day before.


I have the following procedure:
CREATE PROCEDURE [dbo].[sGetRecords]
(
	@DateFrom CHAR(24)
)

AS
SELECT *
  FROM dbo.MyTable
WHERE
	MyTable.ProductionDate >= @DateFrom

Open in new window


However when I call this no records are returned for the previous day (format: 2012-04-10 12:24:13.000), the only way I can get records is if I change it to <= @DateFrom but this returns everything.

I am passing in the date paramter as: 2012-04-10 00:00:00

I have even tried doing a BETWEEN the date parameter and the result of GetDate() however this also brings back nothing.

I'm probably missing something completely obvious, but I've been looking at this for a while now.

First you should try to declare your variable as datetime

CREATE PROCEDURE [dbo].[sGetRecords]
(
	@DateFrom DATETIME
)

AS
SELECT *
  FROM dbo.MyTable
WHERE
	MyTable.ProductionDate >= @DateFrom

Open in new window


Will this give you a correct result?
SELECT *
  FROM dbo.MyTable
WHERE
	MyTable.ProductionDate >= GetDate() - 1

Open in new window

how is

MyTable.ProductionDate

defined?

What sort of data is in the field, is it a date field?

Fantastic that works like a charm.  Can't believe I didn't think of that myself!

Hi,

firstly, you are passing

@DateFrom char(24)

char datatype always takes extra blank.
e.g. if @DateFrom = '2012-04-01'

then with char datatype it will be '2012-04-01              '  extra spaces....

so either change datatype to datetime

or change ur query.

ProductionDate >= convert(datetime, RTRIM(CAST @DateFrom AS VARCHAR(30))), 103)

This will give result.
