Definition and Usage

The CONVERT() function is a general function that converts an expression of one data type to another.

The CONVERT() function can be used to display date/time data in different formats.

Syntax

CONVERT(data_type(length),expression,style)

Value Description
data_type(length) Specifies the target data type (with an optional length)
expression Specifies the value to be converted
style Specifies the output format for the date/time (see table below)

The style value can be one of the following values:

Without century With century Input/Output Standard
-0 or 100mon dd yyyy hh:miAM (or PM)Default
11011 = mm/dd/yy

-130dd mon yyyy hh:mi:ss:mmmAMHijiri
-131dd/mm/yy hh:mi:ss:mmmAMHijiri

Example

The following script uses the CONVERT() function to display different formats. We will use the GETDATE() function to get the current date/time:

CONVERT(VARCHAR(19),GETDATE())
CONVERT(VARCHAR(10),GETDATE(),10)
CONVERT(VARCHAR(10),GETDATE(),110)
CONVERT(VARCHAR(11),GETDATE(),6)
CONVERT(VARCHAR(11),GETDATE(),106)
CONVERT(VARCHAR(24),GETDATE(),113)

The result would look something like this:

Nov 04 2014 11:45 PM
11-04-14
11-04-2014
04 Nov 14
04 Nov 2014
04 Nov 2014 11:45:34:243
