Question

Changing dates in SQL

Asked by: Tigg

I guess it's a simple one but I've tried everything I can think of and I've read about twenty sites. In table dbo.DATA I have a column called DATE_TEMP filled with UK style dates both with century and without eg 31/05/05 and 31/05/2005 and I want to import them into DATE in standard SQL format eg 2005-05-31.

What's the SQL syntax?

Sorry if this is anywhere else but I've spent about three hours on this and simply can't get it to work.

Hi,

Let me get this right...

You have a table called date_temp and in that table there is a SINGLE column containing dates in the form dd/mm/yy and dd/mm/yyyy, so

DATE_TEMP
31/05/05 31/05/2005

or do you have a table called date_temp with 2 columns with a date in each of the forms you mention stored as strings?

Cheers,

Lee

I have a table called DATA

I have two column in that table called DATE_TEMP and DATE

DATE_TEMP has multiple rows with dates in either in century mode ie 31/05/2005 or without the century ie 31/05/05.

I want to run a query that will import this data into column DATE

eg
TABLE dbo.DATA before query :

DATE_TEMP              DATE
31/05/05              
31/05/2005            
30/06/07              

After query:

DATE_TEMP              DATE
31/05/05                  2005-05-31
31/05/2005              2005-05-31
30/06/07                  2007-06-30

Ok, got it...

update date_temp set [date] = left(date_temp, 2) + '-' + right(left(date_temp, 5), 2) + '-' + right(date_temp, len(date_temp) - 6)
