Hi,

I want to get the average of nvarchar.

Here is an example:

Date           Dir<br />
2011/04/19     ESE<br />
2011/04/19     WNE<br />
2011/04/19     ESE

Is possible to get the average of the column Dir in a SQL Proc?

Average of non-numeric characters? Im not aware of such thing. Do you mind explaining further what the scenario is?

I have data every 10 minutes. I want to get the average (once a month) to store in another table. But the data contain numeric and non-numerics values.

what do you mean by average? Average count of same Dir?

You need to break the column data into two columns and then use the average function by converting the date into float.

Following is the example:

SQL

DECLARE @test_date TABLE (dt datetime)

INSERT INTO @test_date VALUES (GETDATE() + 1)
INSERT INTO @test_date VALUES (GETDATE() + 2)
INSERT INTO @test_date VALUES (GETDATE() + 3)

SELECT CONVERT(char(8),CAST(AVG(CAST(dt AS FLOAT) - FLOOR(CAST(dt AS FLOAT))) AS datetime),108) FROM @test_date
