Date/Time Formatting
Hello:
Are there Derby built-in functions which can allow me to extract current date/time as integers as:
Time HHmmss: 103152
Date yyyyMMdd: 20111108
I could get as far as:
cast(current_time as VARCHAR(8)),
cast(current_date as VARCHAR(10)),
but I was unable to find a function similar to str_replace in Sybase to remove “:” and “-“
Thank you,
Pavel.

Thank you, Rick, for your prompt response.
I was able to solve it in the meantime with:
year(current_date) * 10000 + month(current_date) * 100 + day(current_date) as "InsertDate",
hour(current_time) * 10000 + minute(current_time) * 100 + second(current_time) as "InsertTime",
But I was certainly hoping for a more elegant solution (wished there was a format date/time function)...

Hi Pavel,
I don't see a builtin function which does what you want. You might be able to cobble together what you need using the LOCATE and SUBSTR functions, but the statement would probably look ugly. Alternatively, you can register your own user defined formatting function using the CREATE FUNCTION statement:

Hope this helps,
