SQL Server Timestamp Conversion Methods

In SQL Server, a timestamp typically refers to the number of milliseconds or seconds since a specific date (such as January 1, 1970). To convert a timestamp to a datetime format, you can use the following methods:

1. Utilize the DATEADD function:

SELECT DATEADD(ms, your_timestamp_column, '1970-01-01') AS converted_date
FROM your_table;

1. Utilize the DATEADD and CONVERT functions.

SELECT DATEADD(s, your_timestamp_column, '1970-01-01') AS converted_date
FROM your_table;

1. You can utilize the DATEADD and CAST functions:

SELECT DATEADD(s, your_timestamp_column, '1970-01-01') AS converted_date
FROM your_table;

1. Use the CONVERT function and the DATEADD function:

SELECT DATEADD(s, your_timestamp_column, '1970-01-01') AS converted_date
FROM your_table;

Among these methods, the DATEADD function is used to convert timestamps into a date-time format, while the CONVERT and CAST functions are used to convert date-time formats into specific date-time string formats. You can choose the appropriate method based on your needs and data type.
