如何用小数点将秒转换为分钟

Question

I have column that presents number of seconds that took to complete scanning. However I need to translate to minutes and remaining seconds, example if we have 65 seconds I need function to convert to 1.5. I have used datediff() function to retract minutes from start and end datetime stamp but it rounds to nearest minutes.

Answer 1

That is really strange, but you can use strings:

select floor(65 / 60) || '.' || (65 % 60)

Note: This uses standard operators but databases may have their own conventions for string concatenation and modulo arithmetic.
