greenace92 Posted November 20, 2015 Share Posted November 20, 2015 I usually set an ID to 13, does that mean 9999999999999 ? I say 9 as in 0 to 9, I read the manual saying INT 4 -2147483648 2147483647 I don't see how that relates, or is it like 2^13 when I specify 13?

Jacques1 Posted November 21, 2015 Share Posted November 21, 2015 The short version: The display width is irrelevant except for very special cases (like when you use ZEROFILL to pad your numbers with leading zeros). Quote Link to comment Share on other sites More sharing options...
greenace92 Posted November 21, 2015 Author Share Posted November 21, 2015 (edited) Ahh there it is second sentence: MySQL supports an extension for optionally specifying the display width of integer data types in parentheses following the base keyword for the type. For example, INT(4) specifies an INT with a display width of four digits. Assuming that Int(4) translates to Int length 4 as seen in phpmyadmin Edited November 21, 2015 by greenace92 Quote Link to comment Share on other sites More sharing options...
Jacques1 Posted November 21, 2015 Share Posted November 21, 2015 Yeah, but do you understand what “length” actually means in this context? It's irrelevant for you (if it was relevant, you'd know). Quote Link to comment Share on other sites More sharing options...
