Remember the days of 640Kb of ram and 360k disks?
What did you lose by making your database not fit on a disk because you allowed 256chars for an email address and 32768 for a surname?
- callahad 17y agoThat's actually addressed by the original post: The memory used by a VARCHAR or VARCHAR2 data type is dependent on the actual size of the contents, not the maximum size specified. For example, one million email addresses defined using VARCHAR(255) will only take up approximately 23MB, not 255MB.
