How to Convert Integer Time Values to HH:MM:SS::00 Format in SQL Server 2008?

Converting Integer Time Values to HH:MM:SS::00 Format in SQL Server 2008

SQL Server offers a time data type that stores time values in a format similar to 'HH:MM:SS.nnnnn'. However, in certain scenarios, you may encounter time values stored as integers. Fortunately, converting these integer values to the HH:MM:SS::00 format is straightforward in SQL Server 2008.

To convert an integer time value to HH:MM:SS::00, follow these steps:

1. Isolate the Hour: Calculate the hour by dividing the integer value by 1000000 and extracting the remainder by using the modulo operator (%).
2. Isolate the Minute: Calculate the minute by dividing the integer value by 10000 and extracting the remainder by using the modulo operator (%).
3. Isolate the Second: Calculate the second by dividing the integer value by 100 and extracting the remainder by using the modulo operator (%).
4. Isolate the Millisecond: Calculate the millisecond by extracting the remainder of the integer value after dividing by 100 and multiplying it by 10.

For example, if the integer time value is 23421155, the conversion would yield:

• Hour: (23421155 / 1000000) % 100 = 23
• Minute: (23421155 / 10000) % 100 = 42
• Second: (23421155 / 100) % 100 = 11
• Millisecond: (23421155 % 100) * 10 = 55

Therefore, the integer time value 23421155 represents the time '23:42:11:55'.

Clarification on Time Format

In the HH:MM:SS::00 format, the double colon (::) indicates the milliseconds component. It's important to note that this component is always two digits wide, even if the milliseconds value is less than 100. For instance, in the converted time above, '55' represents 55 milliseconds, and if it were only 5 milliseconds, it would still be represented as '05'.

By following the steps and understanding the time format, you can easily convert integer time values to the HH:MM:SS::00 format in SQL Server 2008.
