In T-SQL, a rowversion is a binary data type that is automatically generated and assigned a new value every time a row is inserted or updated in a table. It is also known as timestamp in earlier versions of SQL Server.<\/p>\n

The rowversion data type is primarily used for versioning and tracking changes in tables. You can use it to determine the last time a row was updated or to identify changes to a row.<\/p>\n

To get the time from a rowversion value in T-SQL, you can convert it to a datetime data type using the CONVERT function.<\/p>\n

Here’s an example of how to get the time from a rowversion:<\/h3>\n

 <\/p>\n

DECLARE @rv rowversion = 0x00000000000123AB;<\/code><\/p>\n

SELECT CONVERT(DATETIME, @rv) AS TimeFromRowversion;<\/code><\/p>\n

 <\/p>\n

In this example, @rv is a rowversion value represented as a hexadecimal number. The CONVERT function is used to convert the rowversion value to a DATETIME value, which represents the time when the row was last updated.<\/p>\n

The result of this query will be a DATETIME value that represents the time when the row was last updated.<\/p>\n

It’s important to note that the rowversion value does not store the actual date and time of the row update. Instead, it stores a unique binary value that changes every time the row is updated.<\/p>\n

Therefore, the time obtained from a rowversion value is the time when the row was last updated, not the actual time of the update.<\/p>\n

In addition to using the CONVERT function, you can also use the DATEADD function to add the rowversion value to a base date to get the actual time of the update. For example:<\/p>\n

 <\/p>\n

DECLARE @rv rowversion = 0x00000000000123AB;<\/code><\/p>\n

DECLARE @baseDate DATETIME = '1970-01-01';<\/code>
\n
\nSELECT DATEADD(SECOND, CAST(@rv AS BIGINT), @baseDate) AS ActualUpdateTime;<\/code><\/p>\n

 <\/p>\n

In this example, the DATEADD function is used to add the rowversion value, which is cast to a BIGINT, to the @baseDate value. This gives you the actual time of the row update in DATETIME format.<\/p>\n

Conclusion\u00a0<\/strong><\/h4>\n

To get the time from a rowversion in T-SQL, you can convert it to a DATETIME data type using the CONVERT function, or use the DATEADD function to add it to a base date to get the actual time of the update.<\/p>\n
