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 100 | mon dd yyyy hh:miAM (or PM) | Default |
| 1 | 101 | 1 = mm/dd/yy 101 = mm/dd/yyyy | USA |
| 2 | 102 | 2 = yy.mm.dd 102 = yyyy.mm.dd | ANSI |
| 3 | 103 | 3 = dd/mm/yy 103 = dd/mm/yyyy | British/French |
| 4 | 104 | 4 = dd.mm.yy 104 = dd.mm.yyyy | German |
| 5 | 105 | 5 = dd-mm-yy 105 = dd-mm-yyyy | Italian |
| 6 | 106 | 6 = dd mon yy 106 = dd mon yyyy | - |
| 7 | 107 | 7 = Mon dd, yy 107 = Mon dd, yyyy | - |
| 8 | 108 | hh:mm:ss | - |
| - | 9 or 109 | mon dd yyyy hh:mi:ss:mmmAM (or PM) | Default + millisec |
| 10 | 110 | 10 = mm-dd-yy 110 = mm-dd-yyyy | USA |
| 11 | 111 | 11 = yy/mm/dd 111 = yyyy/mm/dd | Japan |
| 12 | 112 | 12 = yymmdd 112 = yyyymmdd | ISO |
| - | 13 or 113 | dd mon yyyy hh:mi:ss:mmm (24h) | Europe default + millisec |
| 14 | 114 | hh:mi:ss:mmm (24h) | - |
| - | 20 or 120 | yyyy-mm-dd hh:mi:ss (24h) | ODBC canonical |
| - | 21 or 121 | yyyy-mm-dd hh:mi:ss.mmm (24h) | ODBC canonical (with milliseconds) default for time, date, datetime2, and datetimeoffset |
| - | 126 | yyyy-mm-ddThh:mi:ss.mmm (no spaces) | ISO8601 |
| - | 127 | yyyy-mm-ddThh:mi:ss.mmmZ (no spaces) | ISO8601 with time zone Z |
| - | 130 | dd mon yyyy hh:mi:ss:mmmAM | Hijiri |
| - | 131 | dd/mm/yy hh:mi:ss:mmmAM | Hijiri |
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
