在SQL Server 2012中将TEXT转换为日期

Question

I have a TEXT in this format 31/10/15 .

How do I convert this into a DATE format?

As I need to let the user search from data using a date range.

example: From 15/7/13 to 31/10/15

Or is there a way to so without converting to date?

Answer 1

You can use CONVERT() for this:

DECLARE @d VARCHAR(50) = '31/10/50'
SELECT CONVERT(DATE, @d,3)

Note that with a 2-digit year SQL Server will make the year start with '19' for 50 and up, and 49 and below will be '20'

Storing as a DATE field will allow easier comparisons, otherwise you'll have to perform this conversion at each step.

Answer 2

Use CONVERT ; example:

SELECT [Date] = CONVERT(date, '31/10/15', 3);

And yes, it's possible to search dates in the same format as the examples you provide, but don't do that – use the proper data types in both your queries and your table columns.
