Hi,

I am not sure if we can use CONVERT function in INSERT statement; but you can use CONVERT while retrieving Datetime data in the format you want. Check the link below for various formats.

Thank you

I think what I'm seeing is a fundamental misunderstanding of what happens when you store data in SQL. You cannot control the format it is stored as, you put a date/time value in and it stores them ALL the same, regardless of regional settings. If you want a specific format you have to do a CONVERT or CAST when you read the field out. The same is true for all other datatypes as well, for example you want an integer to contain commas at the thousands point (1,000), you can't insert the data that way and expect it to come out the same, it will ALWAYS be stored as 1000 in whatever the format is internally..

Don't fool yourself nor the engine and define the column using data type datetime !

Rule no 1: tell the system what you know !

Rule no 2: use the correct data type !

Sooner or later someone will write queries that will convert your int content to date and/or time trying to filter e.g. day of week, ....

With the date and time data types come a bunch of very useful date and time related functions !

Avoid conversions as much as you can !
