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.
| 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 |
The table below represent the style values for datetime or smalldatetime conversion to character data:
| Value (century yy) |
Value (century yyyy) |
