Question

I have this query that runs fine:

SELECT 
Value
    FROM data
    WHERE MetaDataID = 'f249819e-817f-4be5-bee9-21aa3d7f72e6'

which returns:

27/6/2011 19:12:28
11/7/2011 19:18:54
10/7/2011 11:49:35
3/7/2011 17:41:53

if I Alter the query to:

SELECT 
VALUE,
MONTH(Value)
    FROM data  
    WHERE MetaDataID = 'f249819e-817f-4be5-bee9-21aa3d7f72e6'

I get the error: The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.

Info that might help:

1) The Value Column is VARCHAR type.

2) WHEN I specify the MetaDataId, I make sure the result is “date”. to make sure, I’ve used WHERE IsDate(Value) = 1 too and also I’ve used ISDATe(Value) on the select to see if every result was a date and it was…

I don’t known why this is hapenning… Anybody have a clue?

Answer 1

You have to perform an explicit conversion to a datetime datatype.

SELECT 
VALUE,
MONTH(Convert(DateTime, Value,103)) as [Month]
    FROM data  
    WHERE MetaDataID = 'f249819e-817f-4be5-bee9-21aa3d7f72e6'
