I've been setting the length field in MySQL for as long as I remember and I just realized I don't know why am I doing it...
For example setting an INT type, I always set 11 as length INT(11) and TINYINT(1)(to store Enable/Disable options) , until just now I wanted to use MEDIUMINT and I didn't know what is the max length for this type so I wondered...
I know it's about ZEROFILL, for example INT(4) would display 5 as 0005, but I still have the following questions
My questions are:
- Is it okay to always leave the length blank for Integers? even for Unique keys etc
- Is there any downside in leaving the length blank?
- If it is not important and possibly not even good, then why are most people I've seen and the ones who taught me always put length for
INT/MEDIUMINTetc?
P.S. I always use
UNSIGNEDneverUNSIGNED ZEROFILL
