Mysql column with null values - what are the space requirements? -


i have table quite lot entries. need additional column integer value or null. thing few rows have field populated.

so wonder whether better create seperate table link entries in 1:1 relation.

i know 1 integer entry takes 4 bytes in mysql/myisam. if have column set allow null values, , 100 of 100 000 rows have field populated, rest still consume 4 bytes every null value?

or mysql intelligent enough set value populated , regard null, nothing set?

this depends on row_format value give when create table.

before version 5.0.3, default format set "redundant" : fixed-length field use same space, if it's value null.

starting version 5.0.3, value set "compact" : null values never use space in database.

you can alter table sure use correct format :

alter table ... row_format=compact
